Natural selection acts by taking advantage of natural variations in the traits of organisms within a population what is the ultimate source of this variation

Answers

Answer 1
Answer: The answer is the mutations within the genetic code. 

Natural selection is one of the basic mechanisms of evolution by which species adapt to their environment in order to increase their chance of survival and reproduction. In natural selection, genotype variations that will increase the chance of survival and reproduction of some organism are preserved and will be inherited. But, the sources of this genotype variations are not changes in the environment, nor response to the stress, but the mutations in the genome of the organism. If a mutation is not lethal, it could remain in the population, increasing the variation is some traits.

Answers

The highest point of a wave is called the crest (option B)

What is the crest?

The crest is the highest point of a wave. It is the point where the wave is moving upwards. The lowest point of a wave is called the trough. The word "crest" comes from the Latin word "crista", which means "comb". This is because the crest of a wave resembles the teeth of a comb.

The wavelength is the distance between two consecutive crests or troughs. The height is the vertical distance between a crest and a trough.

What stage of cellular respiration produces pyruvate as a product? Glycolysis
Electron transport chain
Krebs cycle
Fermentation

Answers

glycolysis :) I hope this helped

Final answer:

Pyruvate is produced in the glycolysis stage of cellular respiration, where a glucose molecule is split into two pyruvate molecules. This process occurs in the cell's cytoplasm.

Explanation:

The stage of cellular respiration that produces pyruvate as a product is glycolysis. Cellular respiration is a series of metabolic processes by which living cells produce energy through the oxidation of organic substances. The glycolysis pathway is a 10-step biochemical pathway where a glucose molecule is split into two pyruvate molecules. This process occurs in the cell's cytoplasm. Electron transport chain, Krebs cycle and fermentation are all stages of cellular respiration, but they do not produce pyruvate.

What do aerobic respiration and anaerobic respiration have in common?

Answers

Answer:

Glycolysis.

Explanation:

Aerobic respiration involves complete breakdown of glucose molecule in the presence of oxygen to release 36 molecules of ATP.  On the other hand, anaerobic respiration involves partial breakdown of glucose molecule, when oxygen is absent to release only two molecules of ATP.

Glycolysis is a universal process as it is common in both aerobic and anaerobic respiration. It does not require oxygen and can occur in both presence or absence of oxygen. Glycolysis forms two [pyruvate molecules, two ATP molecules. along with two NADH molecules from one glucose molecule.

Thus, the correct answer is 'glycolysis.'

Both aerobic and anaerobic respiration involve the breakdown of glucose for energy, but aerobic respiration requires oxygen and produces carbon dioxide and water, while anaerobic respiration occurs without oxygen and produces either ethanol or lactic acid.

Aerobic respiration and anaerobic respiration are two different processes that cells use to generate energy, but they share some similarities. Both processes involve the breakdown of glucose molecules to release energy in the form of ATP (adenosine triphosphate). Additionally, both processes occur in the cytoplasm of cells and involve the initial step of glycolysis, where glucose is converted into pyruvate.

However, the key difference between aerobic and anaerobic respiration lies in the final steps. Aerobic respiration requires oxygen and proceeds with the conversion of pyruvate into carbon dioxide and water through the Krebs cycle and the electron transport chain in the mitochondria. In contrast, anaerobic respiration occurs in the absence of oxygen and follows either alcoholic fermentation or lactic acid fermentation, where pyruvate is converted into either ethanol or lactic acid, respectively.

Answers

Answer:

The correct answer is: common ancestor

Explanation:

Hello! Let's solve this!

According to the evolution of living beings, we all have an ancestor.

Depending on the branch in which the living being is, it unites with the ancestor of another.

Two different branches that never join, do not have a common ancestor. In this case, they have a characteristic that unites them, so whales and pythons have a common ancestor.

The correct answer is: common ancestor
