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 1
Answer:

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 .

Explanation:

Hat is most likely to result immediately after a rainforest in Brazil is clear-cut?

Answers

Clear-cutting a rainforest will result to deforestation. It will result in the suffering of the animals in the rainforest and eventually death of the animals. It will destroy the ecosystem in the forest. Some animals will also be extinct because their natural habitat is destroyed. The deforestation rate in Brazil was once the highest in the world. Destroying large areas of rainforest per year. About 600,000 km^2 of the Amazon rainforest was deforested. 

Answer:

Secondary succession.

Explanation:

Clear cutting factors are most likely responsible  for  secondary succession.

which of the following types of mutations would be advantageous for the survival of a cancer cell? a) An inactivating mutation in an oncogene Advantageous: b) An inactivating mutation in a tumor suppressor gene c) An inactivating mutation in a gene that promotes apoptosis d) Methylation of the promoter of a tumor suppressor gene

Answers

Answer choice C is correct. Apoptosis is a programmed death within a cell. What allows cancer cells to rapidly spread so fast is the face that they do not undergo apoptosis, so a mutation that prevents apoptosis will allow the cancer cells to thrive and multiply.

d)the guard cells lose pressure and the stomates close

please helpppppp

Answers

Answer:

1. b. homeostasis: The internal balance of heat within an organism is maintained by the process of homeostasis. It is the ability of the organism to maintain the internal body temperature with respect to the changes that occur in the external environment.

2.d) human: The human beings are capable for maintaining the internal temperature due to homeostasis because they exhibit fat which allows them to maintain the internal heat.

3.c) the guard cell lose pressure and the stomata open: The stomata are small pores present on the underside of the leaf surface these are important for exchange of gases and water to the external environment. The water is lost by the stomata of the leaf during transpiration. When the plant requires to remove excess of water from the plant body it is evaporated from the stomata through transpiration.  

1. Homeostasis
2.Human ( a mammal)
3. B- it should be this, they swell and the stomates close, making the leaf bigger and letting it get more sunlight

Which process breaks down sugars to make atp when oxygen is present

Answers

I'd check this answer but it's between Cellular Respiration and Aerobic Respiration.

Final answer:

Aerobic respiration is the process that breaks down sugars to make ATP when oxygen is present. It occurs in the mitochondria and provides most of the ATP needed for resting or moderately active muscles.

Explanation:

Aerobic respiration is the process that breaks down sugars to make ATP when oxygen is present. This process occurs in the mitochondria and is responsible for approximately 95% of the ATP required for resting or moderately active muscles. Glycolysis is another process that can generate ATP, but it is an anaerobic process that does not require oxygen.
