What causes genetic variation to be preserved or eliminated how does that affect evolution?

Biology
1 answer:
kkurt [141]3 years ago
3 0

Answer: genetic variation is a mutation or a change in the sequence of DNA. It can be preserved if that sequence is needed for a species to survive ( evolution). It can also be preserved if that sequence is strong enough to be passed down from mother to child. The mutation can be eliminated if it causes distress to the animal or if it makes the animals chances of survival smaller. If an extra fin on a dolphin helped it to better escape its predator and better obtain food then this trait may stick around because it is beneficial to the species. If the fin cause the dolphin to swim slower then the dolphin may not survive to reproduce or the trait will not pass on.

Luden [163]

According to the research, the correct option is photosynthesis. The process of <u>photosynthesis</u> generates the oxygen that we breathe and the food that we eat.

<h3>What is photosynthesis?</h3>

It is the process of obtaining energy from plants, algae and certain bacteria to synthesize organic substances from other inorganic ones.

This metabolic process carried out by some cells of autotrophic organisms is essential for life since, starting from light and inorganic matter, it manages to synthesize organic matter and allows carbon dioxide (CO2) to be fixed from the atmosphere and oxygen to be released.

Therefore, we can conclude that according to the research, the correct option is photosynthesis. The process of <u>photosynthesis</u> generates the oxygen that we breathe and the food that we eat.

What is the basic unit of structure and function in protists and monerans?
Alex787 [66]
I believe that the basic unit of structure and function in protists and monerans is the cell. This is because cells are basic unit of structure and function of all living things. A  cell is the smallest unit of life, it is the basic membrane-bound unit that contains the fundamental molecules of life and of which all living things are composed.

Sladkaya [172]

Answer:a. Draw Punnett squares for each couple (you may need to do more than 1 square/ couple)

Baby 2 MUST belong to the Browns because Mr. Brown is the only parent with an A allele to

contribute… then the rest works out as follows:

b. To which parents does baby #1 belong? Why? Hint you may want to refer to your Punnett

squares.

Baby 1 must belong to the Smiths, because they are the only ones with the possibility of EACH

having a recessive allele to pass down to the baby, Mr. Brown has type AB blood and therefore

only has the dominant A and dominant B alleles – no recessive allele possible.

How does human evolution relate to the sensibility of disease
igomit [66]
Human evolution known to be a process in which species adapt to certain conditions of life, and in the battle of life and death, they are forced to become stronger in order to survive in the world. Diseases have always been present during the evolution, acting themselves as a natural selector-the weaker organisms get sick and die.
