After Frida stops exercising, she continues to breathe heavily. What is most likely occurring in her body?A. Heavy breathing during exercise has produced an oxygen surplus in her muscles. This oxygen is being transported to her lungs. This is a result of aerobic respiration.

B. Heavy breathing during exercise has produced a carbon dioxide surplus in her muscles. Lactate is being transported to her liver. This is a result of aerobic respiration.

C.Strenuous exercise has caused her body to be in carbon dioxide debt, and she is breathing hard while lactate is transported to the liver. This is a result of anaerobic respiration.

D. Strenuous exercise has caused her body to be in oxygen debt, and she is breathing hard while lactate is transported to the liver. This is a result of anaerobic respiration.

Answers

Answer 1

Answer:

The correct answer is option D. Strenuous exercise has caused her body to be in oxygen debt, and she is breathing hard while lactate is transported to the liver. This is a result of anaerobic respiration.

During exercise, the muscles use the oxygen present there and become deprived of oxygen. Due to less oxygen, the anaerobic respiration occur in the muscles, to overcome this, the heavy breathing takes place. heavy breathing brings the oxygen to the muscles.

During anaerobic respiration, the glucose is broken down into the lactate and the lactate is transferred to the liver for the gluconeogenesis and to maintain the constant supply of the glucose to the muscles.

A simple diagram of Cori cycle (lactic acid cycle) is given below:

Answer 2

Answer: Out of the choices given, what is most likely occurring in her body is the strenuous exercise has caused her body to be in oxygen debt, and she is breathing hard while lactate is transported to the liver. This is a result of anaerobic respiration. The correct answer is D.

A mutation in a man’s gametes would MOST LIKELY result in which outcome?A) shortening his life
B) intellectual disability
C) a mutation in his offspring
D) a change in his somatic cells

Answers

The answer is C) a mutation in his offspring

The germline mutation is heritable variation in the lineage of germ cells. Germ cells are cells that give rise to the gametes, so a mutation in germ cell will be seen in a sperm cell (man's gamete) but not in a body cell. If present in the sperm cell, after fertilization with an egg cell, the mutation will be present in formed zygote. So, man's offspring will have the mutation

A protein has been used by comparative molecular biologist to show the evolutionary path of how organisms did what things in regards to energy?

Answers

Answer:

Cytochrome C; it provides evidences that there is similarities in the respiratory pathways for producing ATPs by all living organisms especially mammals.

Explanation:

Cytochrome c is located in the intermembranes of mitochondria, and it functions in the transfer of of one electron in electron transport chain,(ETC) needed for generation of proton motive force; for generation of energy in the synthesis of ATPs by ATPase synthase during chemiosmosis. Its allows oxdation-reduction by the switching of its iron ii to iron iii. during electron transports.However its iron atoms does not undergo oxidation with oxygen. This feature makes it stable and an ideal carrier of electrons.

Its amino acid sequences is very similar in all living organisms especially between mammals(e.g man and chimpanzees)with little variation in few amino acid residues due to mutation.This similarity in its amino acids sequences in all living organism together with small molecular size makes it ideal molecular evidence for studying comparative molecular evidence of evolution.

This is because it can be used to trace the pathways of respiration to synthesize energy, and therefore to conclude that most organisms share common ancestry, since a very similar protein sequence in a structure(Cytochrome c) participated in unique ETC mechanisms in all, needed for energy synthesis .

A company estimates its total profit (profit = total revenue minus total cost) as P(x) = 2x5 − 3x4 − 5x2 − 2, where P is in thousands of dollars and x is the number of years elapsed since the company was founded.Solve for the number of times the total profit become exactly zero. Hint: Use Descartes's rule of signs.

Answers

Using the Descartes` rule of signs, we have to recognize how many times the signs change from positive to negative, or from negative to positive from one term to the next. There is only 1 change of signs: from +2 x5 to -3 x4. So we have only 1 real zero.
Answer: There is only one time that the total profit become exactly zero.

The classification levels of a human are listed below from largest to smallest. Eukarya
Animalia
Chordata
Mammalia
Primates
Hominidae
Homo
sapiens
Which level of biological classification do Mammalia and Hominidae represent, respectively?

A)class and family

B)order and class

C)family and species

D)species and kingdom

Answers

Ans.

Biological classification of a species, there are eight levels from largest to smallest, which include domain, kingdom, phylum, class, order, family, genus, and species.

According to this classification system, modern humans can be classified as:

Domain (Eukarya), Kingdom (Animalia), Phylum (Chordata), Class (Mammalia), Order (Primates), Family (Hominidae), Genus (Homo), Species (sapiens).

Thus, levels of biological classification, represented by Mammalia and Hominidae are class and family, respectively.

Class and Family is the answer
