The five main external factors that must be present or provided t sustain life are:
1. Water
2. Oxygen
3. Food
4. Atmospheric temperature
5. Atmospheric pressure
<span>The human body needs water, food and oxygen in order the body functions to work properly.
</span>Not every temperature is temperature at which the human can live. For example: we can not stay alive long period of time at temperature of 60 degrees Celsius.
The endocrine system<span> refers to the collection of </span>glands<span> of an organism that </span>secrete hormones<span> directly into the </span>circulatory system<span> to be carried towards distant target organs. The major </span>endocrine glands<span> include the </span>pineal gland<span>, </span>pituitary gland<span>, </span>pancreas<span>, </span>ovaries,testes<span>, </span>thyroid gland<span>, </span>parathyroid gland<span>, </span>hypothalamus<span>, </span>gastrointestinal tract<span> and </span>adrenal glands<span>. </span>
The answer that would best complete the given statement above is the term NICHE. Each specie has a role in an ecosystem to make it balanced. And an example of this is when s<span>mall monkeys and squirrels both eat nuts and live in tree tops. Hope this answers your question.</span>
My guess:
I do not know the options to the blanks, but I'd say that the answer to the first one is "strongly linked". Think of a chromosome as a phylogenic chart → 2 species that are beside each other are strongly linked, if compared to 2 species 3 spots apart form each other. So, 2 genes that are close to each other are strongly linked.
I do not know the options to the blanks, but I'd say the answer to the second one is epistasis → which is the interaction between two different genes (different means they're not linked alleles).
Hope it helped,
