How do biologists model changes in a population?

Answers

Answer 1

Answer:

When the per capita rate of increase ( r) takes the same positive value regardless of the population size, then we get exponential growth. When the per capita rate of increase ( r) decreases as the population increases towards a maximum limit, then we get logistic growth.

Why is it difficult for your body to return blood from your feet when you sit for too long?. Single choice. a. Blood has to travel a greater distance. B. Skeletal muscles are not squeezing the veins. c. Gravity makes the blood flow backward. d. The heart does not beat fast enough at rest.

Answers

Answer: Option C.

Gravity makes the blood flow backward

Explanation:

it difficult for your body to return blood from your feet when you sit for too long because gravity makes blood flow backward and this is because when you sit for long , it weakens the keg muscles because it is necessary for body movement so that blood will circulate or flow well. When the keg muscles becomes weak, it will slow blood flow in the leg and the force of gravity acting will make the blood flow backward and thus can cause a blood clot.

a Glycolysis
b. Krebs cycle
c Electron transport chain
d. Fermentation

Answers

a. glycolysis thats it

stage of aerobic respiration produces ATP and NADH and releases CO2, which is the electron transport chain that is in option c, as the ETC has a role in the production of ATP in cellular respiration.

What is the significance of respiration in ATP synthesis?

It plays an important role in respiration because it is formed by the oxidation of glucose or other organic molecules in the mitochondria of eukaryotic cells and in the cytoplasm. During respiration, glucose and oxygen are consumed, and carbon dioxide and water are produced, and then the mitochondria make ATP by taking the products of glucose.

Hence, aerobic respiration produces ATP and NADH and releases CO2, which is the electron transport chain that is in option c, as the ETC has a role in the production of ATP in cellular respiration.

I feel like you just answered your own question but I'm going to help you out anyway, active transport utilizes energy from ATP molecules.

Explanation:

The most accurate statement about active transport is active transport utilizes energy from ATP molecules.

Transport active is a type of transport used by cells to move substances against a concentration gradient across cell membranes.

Active transport Is mediated by different membrane proteins known as carrier proteins coupled to an energy source such as, for example, ATP.

During this process (active transport), hydrolysis of ATP provides the energy required to move molecules/ions against a concentration gradient.

In conclusion, the most accurate statement about active transport is active transport utilizes energy from ATP molecules.

Carrying the genetic message from DNA to the ribosomes

The function of mRNA in the diagram given above is carrying the genetic message from DNA to the ribosomes.

What is the function of mRNA?

The main function of mRNA has to work as the immedieter between the protein and DNA which has been  utilised by the ribosome for the process of the direct synthesis of protein, and the function of tRNA has to carry the accurate amino acid to the proteins synthesis site which takes place in ribosome.

RNA has backbone and it has to made up of phosphate group which has been arranged in alternating form and the sugar known as ribose other than the deoxyribose  present in DNA. There are four bases found in RNA and these are adenine, uracil, guanine, and cytosine.

Liquid consist of small range of order and the reason behind this is intermolecular attractive force which is very strong and due to this reason molecules are packed together tightly.
