Answer:
Nitrogen is an essential nutrient for plants and a significant component of proteins, which all animals need to grow, reproduce and survive. The nitrogen cycle converts nitrogen into compounds that plants and animals can use. Humans and Animals Need Nitrogen All human tissue – muscles, skin, hair, nails and blood – contains protein.
Answer:
When gametes combine to form a zygote, the chromosomes number of the zygote is now referred to as <u>diploid</u>.
Explanation:
The term diploid refers to the complete chromosome charge of a cell, in this case a somatic cell. Sex cells, or gametes, contain only half of the chromosome charge that each parent confers on their offspring, and are called haploid cells.
<em>Two gametes, haploids, each contribute their half of the chromosome charge to form a </em><em>diploid</em><em> cell, the </em><em>zygote</em><em>.</em>

Answer:
1:4
Explanation:
30%= 
18%= 
<em>Rewrite the given information:</em>

<em>Multiply by 100 throughout:</em>
30(B -A)= 18(B+A)
<em>Divide by 6 throughout,</em>
5(B -A)= 3(B +A)
<em>Expand</em>
5B -5A= 3B +3A
<em>Bring</em><em> </em><em>A</em><em> </em><em>terms</em><em> </em><em>to</em><em> </em><em>1</em><em> </em><em>side</em><em> </em><em>and</em><em> </em><em>B</em><em> </em><em>terms</em><em> </em><em>to</em><em> </em><em>another</em><em>:</em>
5B -3B= 5A +3A
<em>Simplify</em>
2B= 8A
<em>Divide by 2 throughout:</em>
B= 4A
Now, we have to find the ratio of A to B.
B= 4A
<em>Divide by 4 throughout:</em>
A = 
<em>Divide by B on both sides:</em>

Thus, A:B= 1:4
<u>Answer</u>: There are numerous factors that influence the behavior and physiology of an individual animal/plant etc. By doing the study in their natural environment, you remove any possible bias caused by this.
Furthermore, an individual's behavior will differ in an artificial experimental setup compared to that observed in a natural setting. When possible, studying the subject in its natural environment is the best experimental method.
