Focus on the evolution of horn size in the Bighorn sheep population from 1950 to present. What would you predict would happen if hunting were discontinued for bighorn sheep in a large population?

a) Genotype frequency of H2H2 and H1H2 would increase.
b) We would only see genetic drift, but not evolution by natural selection on horn size.
c) There would be a new mutation for large horns because the females would prefer to mate with males with large horns.
d) There would be a large amount of gene flow between the population where hunting was not allowed and nearby populations where hunting was still allowed.
e) Over time, we could see an increase in the H1 allele frequency.

The correct answer is option e) "Over time, we could see an increase in the H1 allele frequency".

Explanation:

The bighorn sheep (Ovis canadensis) is a species that is a very attractive for hunters because of its long horns. This negative human influence has make that bighorn sheep with long horns struggle to survive and reproduce. Horn size in bighorn sheep is determined primarly by a gene called HRN, which has two alleles H1 (for long horns) and H2 (for smaller horns). if hunting were discontinued for bighorn sheep in a large population we can predict that over time, we could see an increase in the H1 allele frequency, because in this population bighorn sheep with long horns will have better chances of surviving.

The correct option is "Over time, we could see a rise in the H1 allele frequency"

Explanation:

Normally, bighorn sheep populace had a higher recurrence of individual with bigger horns because of sexual choice. Nonetheless, later on, illicit trophy chasing diminished the quantity of bighorn sheep with huge horns as bigger horn yields higher money related advantages. Development implies that a change in allelic frequencies has occurred.  On the off chance that chasing isn't permitted, on the other hand we can anticipate an ascent in the recurrence of sheep's with huge horns (encoded by H1 allele) because of sexual determination (guys with bigger horns can discover female mates and leave offsprings).

question#1

ans:

cell is the basic unit of organization of all living things. cells are often called the building block of life and it is the smallest unit of life. the study of cell is called cell biology. cell consists of cytoplasm enclosed within membrane, which contain bio-molecules such as proteins and nucleic acid.

two third of cell is water, which means that two-third of your whole body is water. the rest is the mixture of molecules, mainly proteins, lipids and carbohydrates.

question#2

ans:

organ:

an organ is a group of tissues specialized to form a functional unit. an example is the heart in animals.

organ system:

an organ system is a group of several organs whose functions are synchronized to release an effective action in a living organism. an example is digestive system.

question#3

different systems perform different function at tissue level. for example, the respiratory system facilitates breathing. in the alveoli tissue of the lungs, the exchange of oxygen and carbon dioxide molecules between the air and the bloodstream occurs by passive transport, so that oxygen is taken in and carbon dioxide and water are removed. different systems of the body carry out different functions. for example, your digestive system is responsible for taking in and processing food, while your respiratory system working with your circulatory system is responsible for taking up oxygen and getting rid of carbon dioxide.

question#5

our body works because of the interactions that happen between organs and organ systems.  

for example:  

the heart to regulate blood flow throughout the body. the blood carries oxygen and nutrients to the cells and carries carbon dioxide and waste away from the cells. body systems work together in maintaining a constant internal environment. when this balance is disrupted, the body systems may not function properly, and human health can suffer.   you start to feel bad.
