b. It is based on the size of seismic waves

Explanation:

just did the test

The statement that describes one aspect of an earthquake's magnitude is: "It is based on the size of seismic waves."

An earthquake's magnitude is a measure of the amount of energy released by the earthquake, and it is determined by measuring the amplitude (height) of the seismic waves generated by the earthquake. The size of the seismic waves is directly related to the amount of energy released by the earthquake, and this is used to calculate the earthquake's magnitude.

The most commonly used scale for measuring earthquake magnitude is the Richter scale, which is based on the amplitude of the largest seismic wave recorded on a seismogram. Other scales, such as the moment magnitude scale, are based on the seismic moment, which takes into account the size of the fault rupture and the amount of slip on the fault.

Answer:

Those capillaries that have endothelial cells tightly attached have an increase in cell-to-cell junctions, such as desmosomal junctions that are poorly permeable to substances.

These capillaries generally function as conductors or collectors and not as permeabilizers like the pulmonary capillaries that are fenestrated and allow a high passage of substances and gases.

The capillaries are waterproof and prevent the passage of substances or fluids such as in the blood-brain barrier that is very selective

Explanation:

The blood-brain barrier is too selective since it is not favorable for the organism that many fluids, drugs, substances or chemical compounds enter the brain space.

This is the reason why the vessels are waterproof and why pharmacology was challenged to invent drugs that could cross this barrier since it was considered impossible.

An example is dopamine, which in parkynson's disease the levo group is added to dopamine, thus forming levodopamine as a product, this is the only way that the drug crosses the blood-brain barrier and can pass the impermeable barrier generated by capillaries with endothelial cells that are close to each other or closely linked

Answer:

Perennation brings adaptive advantages to the plant under unfavorable seasonal conditions

Explanation:

Perennation can be defined as the potential of plants for surviving in unfavorable seasonal periods including, for example, drought or extreme seasonal temperatures. Perennation is a process associated to the evolution of adapted 'perennating organs' capable of storing nutrients, which will be subsequently used during unfavorable conditions. Examples of such perennating organs include bulbs, rhizomes, and tubers, which are usually related to the asexual reproduction processes of plants.

Answer:

Option C is the correct choice.

Explanation:

Some other choices provided do not correspond to the circumstance in question. And the correct response will be Option C.

The statement 'diploid sporophytes that produce spores by meiosis alternate with haploid gametophytes that produce gametes by mitosis' correctly describes the alternation of generations in a plant life cycle (Option C).

In plants, the diploid (2n) sporophyte undergoes meiosis to generate haploid (n) spores.

Subsequently, plant spores undergo successive mitosis to produce multicellular haploid (n) gametophytes.

In the gametophyte phase, a plant produces male and female haploid (n) gametes by mitosis in organs known as gametangia.

The diploid (2n) sporophyte is the zygote produced from the fusion of two (one male and one female) plant gametes. This zygote first develops into an embryo which will give rise to the adult sporophyte by successive mitosis.

In conclusion, the statement 'diploid sporophytes that produce spores by meiosis alternate with haploid gametophytes that produce gametes by mitosis' correctly describes the alternation of generations in a plant life cycle (Option C).

Explanation:

Conditions:

Because the replicated DNA is created, and the cell has twice as much genetic material, cells in the G2 phase have twice as much DNA.

A diploid cell's G1 phase marks the start of the cell cycle (DNA content = 2 N; N is the number of chromosomes).

The cell enters the G2 phase with twice as much DNA (4 N) as the starting cell after DNA replication is finished in the S phase.

DNA replication happens in the S phase, when DNA synthesis happens and the amount of DNA doubles. Once the G1 phase is over, each chromosome contains one chromatid.

Each chromosome will have two chromatids following the S phase, though. The two chromatids here are exact duplicates of one another.

Therefore, When a cell is in the G1 phase, it physically expands and produces more protein and organelles.

Explanation:

Answer: Low.

Explanation:

Lipoprotein lipase or LPL is an enzyme that hydrolyzes triglycerides of low density lipoproteins found in food, and breaks them down to free fatty acids and glycerol. Then they are released into muscle and fat tissue. Without this enzyme, the fat particles would accumulate in the blood. Particularly, lipoprotein particles called chylomicron transport dietary lipids from the intestines to other locations in the body. So these complex, lipids and chylomicron, accumulate in blood.

Fats are a type of nutrient obtained from food. It is essential to eat some fats, although it is also harmful to eat too much. The fats in food give the body the energy it needs to work properly. And, during exercise, the body uses the calories from the carbohydrates that have recently been eaten, but after 20 minutes, exercise then depends on the calories from fat to continue.

So, if the activity of this enzyme is high, the fat in the food is broken down and the person would not gain weight (always considering that there is a correct diet and exercise) On the other hand, if the activity of the protein is low, large amounts of fat accumulate in the blood.

Answer:

The expectations of the bands will be more on the gels.

Explanation:

One sample provides several sizes and thickness bands in the gel electrophoresis according to the size of fragments that run in it. An individual would expect more bands due to the increase in the number of samples which is 20 samples now.

An increase in the number of samples produces more bands. So one can easily expect more bands from the 20 samples. Scientists would get more bands on the gels.

Thus, the expectations of the bands will be more on the gels.

If the scientist collects 20 dung samples ; we should expect more band on the gel

Given that each dung sample has varying sizes and varying thickness of bands in the gel electrophoresis which depends on the size of fragments contained in it. Therefore when a number of dung samples ( 20 ) are collected  it is only logical that the number of bands on the gel will increase ( i.e. you should expect more band on the gel ).

Hence we can conclude that If the scientist collects 20 dung samples we should expect more band on the gel .

Sodium Potassium Adenosine Triphosphatase is in the membrane of cells.  Its function is to create a difference of charges between the inside and the outside of the cell. The enzyme pumps 3 Na+ ions outside the cell for every 2 K+ ions that pumps inside the cell producing a resting potential. As this process is against their concentration gradient, the protein needs the energy to do it. This energy comes from the ATP  that attaches to the transport protein.

Part C: Using the Punnett square to make predictions

Use the completed Punnett square in Part B to answer the questions below about the F2 generation.

Note: You will find the Punnet square in the attached files.  

Note that questions 3 and 4 require a more advanced evaluation of probabilities than do questions 1 and 2 because you have to consider all possible groupings and orders of three F2 seeds. If you need help with these calculations, use Hint 3.

1) What is the probability that an F2 seed chosen at random will be yellow?

2)  What is the probability that an F2 seed chosen at random from along the yellow seeds will breed true when selfed?

3) What is the probability that three F2 seeds chosen at random will include at least one yellow seed?

4) What is the probability that three F2 seeds chosen at random will include one green seed and two yellow seeds?  

Answer:

1) 3/4              

2) 1/3

3) 63/64

4) 27/64

Explanation:

Parental) Yy   x   Yy

Gametes) Y   y   Y   y

Punnet Square)

                      (1/2) Y            (1/2) y

      (1/2) Y    (1/4) YY         (1/4) Yy

      (1/2) y     (1/4) yY          (1/4) yy  

F2)  1/4 YY

      2/4 = 1/2 Yy

      1/4 yy

1) There will be 3/4 of probabilities of getting a yellow F2 seed

   1/4 YY + 2/4 Yy = 3/4 Y-

   The symbol "-" means that in its position there might be either a Y or y allele.

2) As there are only three yellow possible genotypes for yellow seeds, the fourth genotype for green seeds is not considered. Our pool now is only yellow seeds. So the probability of getting a pure breeding yellow seed among all yellow seeds is 1/3.  

   1/3 YY

   1/3 Yy

   1/3 yY

In the pool of yellow seeds, there are three genotypes, and only one of them corresponds to pure breeding yellow seed.

3) To calculate the probability of getting at least one yellow seed among the three seeds randomly chosen, we need to multiply and then perform addition. This is, when we take three seeds from the pool, we have different possibilities of getting seeds with different genotypes. So:

There might also be one green sees and two yellow seed, so we multiply their probabilities in the order in which we might get them. This is:

And we could also get two green seeds and only one yellow seed:

Now, having all the possibilities, we just need to add all the possibilities:

27/64 + 9/64 + 9/64 + 9/64 + 3/64 + 3/64 + 3/64= 63/64.

Note that we did not include the possibility of getting three green seeds (1/4 x 1/4 x 1/4). This is because we were asked to calculate the probabilities of getting AT LEAST one yellow seed.

4) To calculate the probability of getting two yellow seeds and one green seed among the three seeds randomly chosen, we should multiply probabilities and then sum them up.

The orders in which we could get the seeds are:

Now, having all the possibilities, we just need to add all the possibilities:

6/64 + 9/64 + 9/64 = 27/64.

Answer:

1) 3/4

2) 1/3

3) 63/64

4) 27/64

Explanation:

1) yellow seed could either be GG, Gg or Gg from Punnett square, therefore, there is a 3/4 probability

2) true-breeding = either GG or gg. Therefore, out of the 3 yellow seed options, only 1 is true-breeding, therefore, it's a 1/3 probability

3) "there are 7 possible groupings that have at least 1 yellow seed; the sum of their individual probabilities yields the final answer of 63/64. Note that you could have also calculated this answer by subtracting the probability of the one category that doesn’t fit the criterion (Green, Green, Green) from the total probability (1 – 1/64 = 63/64)"

4) "there are 3 possible groupings that have 1 green and 2 yellow seeds; the sum of their individual probabilities yields the final answer of 27/64"

Answer:

A carbon footprint is the total greenhouse gas (GHG) emissions caused by an individual, event, organization, service, or product, expressed as carbon dioxide equivalent.[1] Greenhouse gases, including the carbon-containing gases carbon dioxide and methane, can be emitted through the burning of fossil fuels, land clearance and the production and consumption of food, manufactured goods, materials, wood, roads, buildings, transportation and other services.[2]

In most cases, the total carbon footprint cannot be calculated exactly because of inadequate knowledge of and data about the complex interactions between contributing processes, including the influence of natural processes that store or release carbon dioxide. For this reason, Wright, Kemp, and Williams proposed the following definition of a carbon footprint:

Specifications that reduce carbon dioxide expenditure and promote biodiversity are as follows:

1. Provide tree plantation through urban afforestation.

2. It has low concentration of carbon dioxide as plants absorb this gas and release oxygen

3. By promoting fruits and shade for the neighborhood.

Carbon dioxide is defined as the chemical compound which is made up of molecules each containing a carbon atom bonded twice to two oxygen atoms and is found in the gaseous state at room temperature. In air, carbon dioxide is transparent to visible light but absorbs infrared radiation which acts as a greenhouse gas.

This is a minor component of the Earth's atmosphere at about 3 volumes in 10,000 employed by plants in the combustion of carbon-containing material, in fermentation, and in the respiration of animals and in the photosynthesis of carbohydrates.

Thus, specifications that reduce carbon dioxide expenditure and promote biodiversity are as follows:

1. Provide tree plantation through urban afforestation.

2. It has low concentration of carbon dioxide as plants absorb this gas and release oxygen

3. By promoting fruits and shade for the neighborhood.
