C. protein. Nitrogen is a component of amino acids which are the building blocks of protein.
There are two types of cell division: mitosis and meiosis. Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells.
Mitosis is a fundamental process for life. During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells. Because this process is so critical, the steps of mitosis are carefully controlled by a number of genes. When mitosis is not regulated correctly, health problems such as cancer can result.
The other type of cell division, meiosis, ensures that humans have the same number of chromosomes in each generation. It is a two-step process that reduces the chromosome number by half—from 46 to 23—to form sperm and egg cells. When the sperm and egg cells unite at conception, each contributes 23 chromosomes so the resulting embryo will have the usual 46. Meiosis also allows genetic variation through a process of DNA shuffling while the cells are dividing.
Cattle can see at night because they have light-reflecting surface called tapetum lucidum. This area allows the light that enters the eyeball to reflect within the eye, amplifying the low levels of light

Explanation:
First, think about which base pairs arise in complementary strands of DNA:
DNA → DNA
adenine → thymine (A → T)
thymine → adenine (T → A)
cytosine → guanine (C → G)
guanine → cytosine (G → C)
However, mRNA does not consist of the same four bases as DNA. While DNA has the ATCG nitrogenous bases, RNA replaces thymine with uracil, making its bases AUCG.
So, that means that whenever DNA has adenine, instead of pairing this with thymine, RNA will use uracil instead.
DNA → RNA
adenine → uracil (A → U)
thymine → adenine (T → A)
cytosine → guanine (C → G)
guanine → cytosine (G → C)
Giving us the corresponding sequence:
