Group 1 receives 1 ounce of fertilizer, Group 2 receives 2 ounces, Group 3 receives 3 ounces and Group 4 receives no fertlizer. The plants receive the same amount of water, sunlight and humidity. She counts the number of flowers on each plant at the end of one month. What is the independent variable in the study?

a. number of flowers
b. height of plant
c. amount of water
d. amount of fertilizer

2. Think about an animal like a rhinoceros, a deer, or an antelope. What parts of their body other than their hair must be composed of quite similar material to your nails and hair

Answers

Answer:

horns and hooves

Explanation:

horns and hooves are made of kerotin, just like nails and hair.

Keratin is the protein that composes the external layers of the epidermis. It can be found in elements like feathers, nails, and hair. Other parts of the body that might be composed of keratin are horns and hooves.

-------------------------------------

Keratin is a fibrous protein that can be found in epithelial cells that cover internal and external surfaces.

Keratin is the main component of horns, hooves, feathers, hair, and nails.

Horns are hollow and pointed structures that emerge from the skull of the animal.

Animals get born hornless. As they grow they develop these structures. Most of them complete the development near the reproductive stage of the animal.

At sexual maturity age, competitive interaction increases, and animals use them to defend themselves and hurt the opponent. Males of some species also use them to attract females.

Hooves are very developed nails that cover the ugunaltes' fingers. These animals only use the extreme of the fingers to walk.

Like all nails, hooves grow continuously and wears out as the animal walks or runs.

a. osteons, canaliculi
b. lamellae, canaliculi
c. osteons, lamellae
d. Haversian canals, lamellae
e. none of the above

Answers

Answer:

The correct answer is c. osteons, lamellae

Explanation:

An osteon is the basic functional unit of the cortical bone of a tubular bone. An osteon consists of a central canal that contains two vessels of Havers. Concentric bony laminae are arranged around this canal. These lamellae consist of bone cells and the surrounding base substance. Between the Havers canals there are Volkmann canals that connect the Havers canals. The construction of the cortical bone in these functional units has not yet been fully clarified. In general, it is assumed that these structures serve primarily to deliver tissue and signal transduction. This structure is also supposed to serve the stability and adaptability of the bone.

If 100 grams of vinegar and 5 grams of baking soda are poured in a container, a small amount of gas will be produced. What will the final mass of the products be if the gas is trapped in the
container?

Answers

Answer: I think it is 105 grams

Explanation: Because classic chem and math states 100+5= 105

The final mass of the products if the gas is trapped in the container will be 105 g

From the law of conservation of matter, we understood that mass can neither be created nor destroyed during a chemical reaction but can be transferred from one form to the other.

This implies that the total mass of  reactants must be equal to the total mass of products i.e

Total mass of reactants = Total mass of products

Considering the question given above, the following data were obtained:

Mass of vinegar = 100 g

Mass of baking soda = 5 g

Total mass of reactant = 100 + 5 = 105 g

From the question given above, we also discovered that the gas produced were trapped in the container.

This simply means that the total mass of reactants (i.e 105 g) will also be equal to the total mass of the products.

Thus, the total mass of the products is 105 g.

What is a Chemical reaction?

A chemical reaction may be defined as a mechanism that significantly directs the chemical transformation of one set of chemical substances or molecules to another. This process of chemical transformation utilizes numerous catalysts to enhance the rate of reaction.

The amount or number of chemical substances or molecules that are present before the progression of reaction are known as reactants.

While after the successful progression or completion of a specific chemical reaction such reactants are performed into another, these substances or molecules are known as products.

Both the molecules of reactants and products possess some sorts of chemical identity in order to distinguisg from each other.

Explanation:

The most common methodologies used to determine protein 3D structure are nuclear magnetic resonance (NMR) and X-ray crystallography. Although both methods are efficient, the determination of 3D protein structures in physiological conditions is a time and cost-consuming task. Moreover, due to recent advances in bioinformatics and sequencing methodologies, the amount of protein Open Reading Frames predicted from sequencing data (especially obtained from Next Sequencing Generation studies) is many times higher.

c: a cycle if processes by which water circulates the earth's oceans , atmosphere , and land.

Answers

Answer:

C. A cycle of processes by which water circulates the earth's oceans, atmosphere, and land.

Explanation:

The term water cycle (also called the hydrologic cycle or the hydrological cycle) refers to the way water moves on, above, and below the surface of the Earth.

As the sun heats up the surface of our planet, water evaporates from it, rises up into the atmosphere, cools, and turns into rain or snow in clouds. Then, in this form, it falls on the surface again. This cycle constantly repeats itself, which means that water moves all the time.

Farmers have selected for increased oil content from corn. For a long time, the plants responded with steadily increasing oil content, but recently the response slowed and then stopped. When this line of corn is crossed to another line and the hybrids are selected, the oil content resumed its climb. What is a plausible reason for the lack of response?
A. The environmental conditions improved.
B. The genetic variation for the trait was exhausted.
C. There was too much genetic variation for the trait.
D. The environmental conditions deteriorated.
E. Artificial selection is different than natural selection.

Answers

Answer:

B. The genetic variation for the trait was exhausted.

Explanation:

Oil content is a quantitative trait, ie., a phenotypic feature that depends on the accumulative effects of many genes and the interaction of a genotype with its environment. During crop improvement, the plants (i.e., lines) containing desired alleles involved in the variation of this trait will be selected, thereby increasing oil content but simultaneously decreasing the genetic variation of the population. In consequence, after successive rounds of artificial selection, lines will not have sufficient genetic diversity to be again selected for this trait.

Approximately how many molecules of ATP are produced by substrate-level phosphorylation during the complete oxidation of a molecule of glucose (C6H12O6) in aerobic cellular respiration?

Answers

The answer is believe is (4)

Approximately, there are four molecules of ATP are produced by substrate-level phosphorylation during the complete oxidation of a molecule of glucose (C6H12O6) in aerobic cellular respiration.

What is Cellular respiration?

Cellular respiration may be defined as a type of biological process that significantly involves the breakdown of food in the cell with the liberation of energy.

In a more simple sense, it is a process of transforming glucose into a form of energy that is known as ATP which is utilized by cells in order to accomplish metabolic and cellular activities.

Two molecules of glyceraldehyde-3-phosphate are formed from one molecule of glucose. Each molecule of G-3-P is responsible for the formation of 2 ATP during the process of substrate-level-phosphorylation.

Hence, a total of four ATPs are produced via the reaction that is known as substrate-level phosphorylation.

Therefore, the number of ATPs that are produced by substrate-level phosphorylation during the complete oxidation of a molecule of glucose is four.
