Answer:

Cytochrome c is an enzyme found in bacteria, fungi, plants and animals. Here it is given that the human amino acid sequence for cytochrome c differs at 12 locations from the sequence in horses and pigeons. This information might be useful for inferring in preliminary stages that horses and pigeons are closely related to each other since they both show similar amount of difference from humans.

However, this hypothesis is being made with respect to the the comparison between "humans and horses" and "humans and pigeons". To further test this hypothesis pigeons and horses should be directly compared to each other without the use of a third species like humans. Hence, the sequence for cytochrome c in horse and pigeon should be compared with each other rather than comparing to humans.

when matter i’m plants and animals decay, microorganisms responsible for the decomposition process are doing cellular respiratio
uysha [10]

Answer:

Yes, when the plants and animals die, decomposers such as bacteria and fungi etc which are microorganisms feed on these dead bodies of plants and animals and broken down their bodies into simpler substances. This decomposition occurs both with oxygen and without oxygen. When energy is released with the addition of oxygen, this process is called aerobic respiration while when energy is released without the use of oxygen, this process is called anaerobic respiration.

Which of the following is NOT an example of a selection pressure?
Lena [83]

Answer:

B. Surgery

Explanation:

I am not entirely sure but based on the definition of selection pressure (which talks about how external agents affect the survival of an organism) surgery is does not meet the definition.

A tiger hunting a prey affects the survival of prey. Beginning of ice age is an environmental agent that can affect survival of organism that cant tolerate cold. Antibiotics are drugs that can kill bacteria thus lower their survival. Surgery can actually increase survival if some form of disease is being treated.

Previous research shows that, in humans, the pelvic opening tends to be wider in females than males
Natalka [10]

Answer:

1. Pelvis is wider in females due to it is an anatomical feature that allows the childbirth

2. A study aimed at determining if the size of the pelvis shows association with problems during childbirth

3. Females with smaller pelvis frequently have problems during childbirth

4. Populational biases in the data regarding ethnicity, age, etc

Explanation:  

A hypothesis is a proposed explanation for a given phenomenon from the real world. A scientific hypothesis needs to be tested by experimentation or observational procedures. A good hypothesis must fulfill two key requirements  1- it must be-testable, i.e., capable of being proved by using the scientific method, and 2-falsifiable, i.e., it must have a possible negative answer.
