Mutation is a source but it is not the main source after it comes recombination in which 2 chromosomes with “normal” survival are taken from natural population of Drosophila and combined. Then comes immigration of genes in which the new chromosome mix in with different gene frequencies.
If you were to look at the age structure of a population of an endangered species and determine that there are mostly older individuals you could say that the population is declining and could be in danger of extinction.
<h3>What are
endangered species?</h3>
An organism that faces extinction is referred to as an endangered species. The two main factors that cause a species to become endangered are habitat loss and genetic diversity loss.
Because it prevents our native fish, plants, and other animals from going extinct, the Endangered Species Act is crucial. There is no turning back once they are gone they are lost forever.
Endangered species are those that are at risk of going extinct and must therefore be safeguarded and conserved. Extinct species are those that no longer exist on the planet.
It's Important to Save Endangered Species because:
- From antibiotics to anti-cancer medications, they are the sources of those substances.
- They are the earliest indication of significant environmental problems.
- They support the well-being of crops (and, indirectly, people).
- They help the economy grow.

Answer:
I don't know correct answer but I think it is <em>night time</em> in b point.
Answer:
<u>
Essential</u> nutrients cannot be synthesized by the human body but are required for optimal functioning. Therefore. They must be obtained from food. Omega-3 fatty acids are prime examples.
You consume macronutrients (water. proteins, carbohydrates, and fats) in large quantities as opposed to <u>micronutrients</u> which you consume in small quantities
<u>Dehydration</u> can develop very quickly when exercising in hot/humid weather conditions.
<u>Proteins</u> are also called 'bodybuilders" due to their function within the body. <u>Amino acids</u> are the building blocks of proteins.
Explanation:
Essential nutrients are those nutrients that are required for the proper functioning of the body but cannot be synthesized by the body. They are obtained from external sources such as vegetables or synthesized artificially in the laboratories. Micronutrients as the name implies are taken in small amounts. Examples are the different types of vitamins.
Dehydration occurs when a person loses a good amount of water through sweating or urination. It can easily occur while exercising in hot weather conditions. Proteins repair the cells in our body and are, therefore, rightfully referred to as bodybuilders. Amino acids form proteins.
Answer:
Multicellular organisms are made of more than one cell and are complex organisms.
They are visible to the naked eye.
They possess distinct organs and organ systems.
They are eukaryotes, i.e., they contain membrane-bound structures.
Their cells exhibit division of labor.
Their size increases with the number of cells in an organism
Explanation:
