The answer is A

Explanation:

You can tell because the way that it is

Answer:

Yes.

Explanation:

Yes, cloning is a form of asexual reproduction because there is no fusion of sperm and eggs takes place. the animal which is formed from this process is identical of that organism because it is produced from the tissue of that single animal. in 1996, first mammal is produced from cloning was sheep named dolly at the Roslin Institute in Scotland. In cloning, the egg is taken from female organism and remove the nucleus from the egg then the desired organism cell is taken and fuse with the nucleus with the help of electricity. Then implant this embryo in the body of first organism from where egg is taken and after that the embryo turns into a baby, this process is called cloning.

Answer:

Yes, cloning is a form of asexual reproduction. The diagram shows that new plants form from a single parent plant, which means that the offspring are genetically identical to the parent.

Answer:Experiment 1084-04: lodine Clock Reaction Purpose Determine the rate law for an iodine clock reaction and study the influence of st on that reaction abruptly that it can be as startling as the sudden sound of an alarm clock, hence the clock reaction Background Information chemical equations can be written for chemical reactions, only some will proceed while others do not. Among the ones that do proceed some reactions occur as soon as reactants are mixed, while others occur over minutes, hours, or n over several years. What are the controlling in predicting if a reaction will take place and the speed at which it will? Thermodynamics can answer the question, "Will the reaction take place?" Once the reaction is capable of proceeding kinetics can answer the other question, "How fast You will study the rate of the reduction of potassium persulfate, KoS Os, with sodium iodide, Nal. The net ionic equation for the reaction is eve The rate law for this reaction is in the form of And you will need to determine the reaction orders a and b, as well as the rate constant, k. Keep in mind that exponents can not be determined by jus looking at the chemical equation the reaction will take place? The rate of a reaction is defined as the increase in molar concentration of product of a reaction per unit time or the decrease in molar concentration of reectant per unit time. The usual unit for the rate is moles per liter per sec (mol/L s or M/s). Experimentally, it has been found that a reaction rate depends on the concentrations of the reactants. Usually a higher reactant concentration increases chance of collision among the reactants per unit time causing a faster reaction rate. An equation describing the relationship between the reaction rate and the concentration of the reactants You will need a way to determine how much of the reactants were spent over the given time period. Preferably, the concentrations of the reactants should not change too much; therefore the reaction rate can be represented by the initial concentrations of reactants (the initial-rate method). In this experiment, we will couple another reaction that consumes the product, 12 very quickly. The new reaction is the reduction of is called a rate law. For the elementary reaction Note that l2, which was produced in reaction (1) is consumed as fast as it is produced by reaction (2) to regenerate two l. i.e. [门is kept constant. By keeping [S203-9 much smaller than the initial concentration of S,0, we can assure [S20,1 is also kept nearly constant when S203 is completely consumed. At this point, the 12 is no longer eliminated by the reaction and starts to accumulate. This point is signaled by sudden appearance of the dark color from the interaction of l2 with starch indicator. We can measure the time elapsed till the color appears Rate k [AIB] The proportionality constant, k, is called the ate constant in the relationship between the rate nd concentrations. The rate constant has a fixed alue as long as the reaction temperature is held nstant. The exponents, a and b, are called the action order, and are frequently, but not always, egers. More importantly, they must be termined experimentally In this experiment you will determine the rate an iodine clock reaction, and study the effects of perature and a catalyst to the reaction rate ugh there are several versions of an iodine k reaction, all of them share a common feature: completion of the reaction is signaled by the en appearance of a dark purple color. This is characteristic of the interaction between cular iodine and starch. When the reaction is ed out correctly, this color will appear so According to the reaction stoichiometries of reactions (1) and (2), two molecules of S203 are required to counteract the consumption of one molecule of S20a2. Since S2032 would have been completely consumed when the dark purple color appeared, the Δ[SO ] should be % of the initial concentration of S203 15-08-2] = ½ initial [S,03-21

Answer:

D, the fossil in the Cambrian period

Explanation:

there are time periods on the left side that go from youngest on the top and oldest on the bottom

In the labeled diagram the fossils comes from the oldest organism an index fossil from the Cambrian period is labeled at the point D. Thus, option D is correct.

Index fossils, which is also known as the key fossils or the guide fossils, are fossils of the organisms that are used to help determine the age of rock formations and sedimentary strata. Index fossils are typically chosen because they are easily recognizable, widespread, and existed for a relatively short period of time.

They are used as "markers" for specific time periods, and the presence or absence of certain index fossils can help scientists determine the relative age of rock formations.

In this scenario, the index fossil labeled A is from the Jurassic period, which lasted from about 201 to 145 million years ago. The index fossil labeled B is from the Permian period, which lasted from about 299 to 251 million years ago.

Therefore, In the labeled diagram the fossils comes from the oldest organism an index fossil from the Cambrian period is labeled at the point D. Thus, option D is correct.

Complete Question:

Part A: Identifying Variables

Read the following hypotheses and identify the variables.

If the number of cigarettes smoked increases, then the risk for lung cancer increases.

Independent variable: _______

Dependent variable: _______

If the number of sharks swimming in a coastal region increases, then the number of shark attacks on humans will also increase.

Independent variable: _______

Dependent variable: _______

If the amount of milk a person drinks increases, the strength of his or her bones will stay the same.

Independent variable: _______

Dependent variable: _______

Answer/Explanation:

Dependent variables are variables that is dependent on the independent variables. That is, it is the variable that changes as the independent variable changes.

Depedent variable is the main interest if a researcher. It is the variable that is measured in a research work.

In the above given hypotheses, the dependent and independent variables are shown below:

1. "risk for lung cancer" is dependent on the "number of cigarettes smoked".

"Risk for lung cancer" => dependent variable

Number of cigarettes => independent variable

2. "number of shark attacks on humans" is dependent on "number of sharks swimming".

Dependent variable => number of shark attacks on humans

Independent variable => number of sharks swimming

3. Dependent variable => strength of bone

Independent variable => amount of milk a person drinks

Answer:

Lab: Heart Rate  

Part A: Identifying Variables

The dependent variable happens as a result of values/changes associated with the independent variable.

Independent variable: number of cigarettes smoked

Dependent variable: risk for lung cancer

Independent variable: number of sharks swimming in a coastal region

Dependent variable: number of shark attacks on humans

Independent variable: amount of milk a person drinks

Dependent variable: the strength of his or her bones

Part B: Heart Rate

Hypothesis: If I hold my breath for 30 seconds, then my heart rate will

(choose 1) increase/decrease.

Independent variable: holding my breath

Dependent variable: heart rate

Part C:

The heart rate decreases because oxygen exchange in the lungs decreases.

This depends on what you chose for heart rate in the hypothesis. If you said the heart rate decreases after holding your breath, and the results showed the heart rate decreased, then the hypothesis is supported. If you said the heart rate decreases after holding your breath, and the results showed the heart rate increased, then you refuted the hypothesis.

Heart rate can change due to an increase or decrease in activity, moving positions such as sitting and standing, and emotions.

Example: Increase in activity—jumping jacks

Hypothesis: If I do five jumping jacks, then my heart rate will increase.

Test hypothesis. You can use the average resting heart rate from the previous experiment. If you do an experiment with an increase in physical activity like jumping jacks, then your data will reflect an increase in heart rate because the body requires more energy, which requires more oxygen, increasing the overall flow of blood in the body.

Support or refute the hypothesis based on the results. The hypothesis is supported if it aligns with the observed results. The hypothesis is refuted if the results don’t match the statement based on the variables.

Testing more than one variable at a time makes it difficult to interpret the results and support or refute the hypothesis. With one variable, the results can be associated with changes to that variable. To get the most reliable data to support or refute a hypothesis, an experiment should be completed several times to see if the results show the same trends.

Answer:

Weathering:

2. Cracks form in a sandstone wall surrounding a house.

3.A marble statue near the science museum is changing color due to rainfall.

Erosion:

1. The Colorado River carves land in Arizona to form the Grand Canyon.

4. After a rainstorm, soil and rock pieces litter the roadways.

5. The sand dunes in the Sahara Desert are changing shape.

Explanation:

Weathering and erosion, in both the processes rocks are broken down into particles but both the processes are different from each other. Weathering can be physical, chemical or biological process in which rock particles degrade without any movement while erosion is purely a movement of sediments in which particles move from one place to another under the influence of water and wind.

So, on the basis of this difference we can classify each label to the correct location:

Weathering (no movement of particles after degradation):

2. Cracks in a sandstone wall of a house.

3. Changing color of marble statue due to rainfall.

Erosion (Movement of particles from one place to another):

1. Formation of Grand Canyon, when the Colorado River carves land in Arizona.

4. Soil and rock pieces litter on roadways after rainstorms.

5. Changing shape of dunes in sahara desert.

Answer:

weathering - colorado river carves land in arizona to form the grand canyon. cracks form in a sandstone wall surrounding a house. a marble statue near the science museum is changing color due to rainfall

erosion - after a rainstorm, soil and rock piees litter the roadways. the sand dunes in the sahara desert are changing shape.

Answer:

Objective Lens Magnification = ×100

Explanation:

In a microscope, the ocular (eyepiece) lenses are usually to a magnification of ×10, meaning that it magnifies the image 10 times. While the standard objective lenses have magnifications of ×4, ×10, ×40, and ×100.

In order to work out the total magnification, the individual magnifications of the ocular and objective lenses have to be known, after which a simple multiplication of both magnifications will give the total magnification used.

Total Magnification = (eyepiece lens magnification) × (objective lens magnification)

1000 = 10 × obejcetive lens magnification

Dividing both sides by 10

Objective lens magnification = 1000 ÷ 10 = 10

∴ Objective lens magnification = ×100

Answer:

If we do not reduce our carbon emissions and instead allow global temperatures to rise by 4.5˚C, up to half the animals and plants in some of the world’s most biodiverse areas could go extinct by 2100, according to a new study. In fact, even if we are able to limit global warming to the Paris climate agreement goal of 2˚ C, areas such as the Amazon and the Galapagos could still lose one quarter of their species, say the researchers, who studied the effects of climate change on 80,000 plants and animals in 35 areas. Another study found that local extinctions (when a species goes extinct in a particular area, but still exists elsewhere) are already occurring in 47 percent of the 976 species studied, in every kind of habitat and climatic zone.

With temperatures rising, precipitation patterns changing, and the weather getting less predictable and more extreme, a 2016 study determined that climate change is already significantly disrupting organisms and ecosystems on land and in water. Animals are not only shifting their range and altering the timing of key life stages— they are also exhibiting differences in their sex ratios, tolerance to heat, and in their bodies. Some of these changes may help a species adapt, while others could speed its demise.

Move, Adapt or Die

Animals can react to climate change in only three ways: They can move, adapt or die.

According to climate change If carbon emission can't reduced and instead allow global temperatures to rise by 4.5˚C, up to half the animals and plants in some of the world’s most biodiverse areas could go extinct by 2100.

Climate change refers to long-term shifts in temperatures and weather patterns. These shifts may be natural, but since the 1800s, human activities have been the main driver of climate change, primarily due to the burning of fossil fuels (like coal, oil, and gas) which produces heat-trapping gases.

More frequent and intense drought, storms, heat waves, rising sea levels, melting glaciers and warming oceans can directly harm animals, destroy the places they live, and wreak havoc on people's livelihoods and communities.

The potential future effects of global climate change include more frequent wildfires, longer periods of drought in some regions, and an increase in the duration and intensity of tropical storms.

According to google your answer's are as follows

I} Parasitism means the relationship between two species of plants or animals in which one benefits at the expense of the other, sometimes without killing the host organism.

II} Photosynthesis is a biological process utilized by all green plants to synthesize their own nutrients. The process of photosynthesis requires solar energy, water and carbon dioxide.

Answer:

Root hairs are where most water absorption happens. ... The function of root hairs is to collect water and mineral nutrients that are present in the soil and take this solution up through the roots to the rest of the plant. As root hair cells do not carry out photosynthesis they do not contain chloroplasts.

Explanation:

The cell walls, chloroplasts, and mitochondria play important roles in plant cells, they are not directly involved in building protein molecules under the control of the nucleus. D

Ribosomes are the structures in plant cells that build protein molecules under the control of the nucleus.

Ribosomes are tiny, complex molecular machines composed of RNA and protein molecules.

They are involved in the process of protein synthesis, where they facilitate the translation of genetic information from the DNA in the nucleus into functional proteins.

The nucleus of a cell contains the DNA, which serves as the blueprint for building proteins.

However, the actual synthesis of proteins occurs in the cytoplasm, outside the nucleus.

Ribosomes are responsible for this task.

Ribosomes can be found both freely floating in the cytoplasm and attached to the endoplasmic reticulum (ER).

The ones attached to the ER are called rough endoplasmic reticulum (rough ER) due to the presence of ribosomes on their surface.

These ribosomes associated with the rough ER are involved in the synthesis of proteins that are destined for secretion or for integration into the cell membrane.

The process of protein synthesis involves the decoding of the genetic information stored in messenger RNA (mRNA) by ribosomes.

Ribosomes read the mRNA sequence and assemble amino acids into a growing polypeptide chain, forming a functional protein.

Cell walls provide structural support, chloroplasts are responsible for photosynthesis, and mitochondria are involved in cellular respiration. However, the primary site for protein synthesis in plant cells is the ribosomes.

Therefore, the ribosomes (option d) are the structures in plant cells that build protein molecules under the control of the nucleus.
