Answer:
Because DNA molecules are extremely long.
Explanation:
DNA molecule is made up of only four types of nucleotides that are adenine, guanine, cytosine, and thymine. These four types of nucleotide encode all the information necessary for the formation and working of the entire organism because each DNA strand is as long as 2 meter which contains millions of base pairs.
The four nucleotides are arranged in the DNA strand with many different combinations which results in the formation of codons sequence that contains all the information about the cell. This long DNA is compressed several times to fit in the nucleus.
Living things cannot live without eachother due to the food chain, if an animal loses it's food so will his predator and so on. Soon they will end up extinct, this is why it's important to take care of animals.
Mastication is the process by which food is crushed and ground by teeth. It increases the surface area of foods to allow a more efficient break down by enzymes.
Answer:
Explanation:
Number 1: The answer is A; Ariginase is responsible for the release of urea as product.
Number 2: The answer is B; Argininosuccinate synthetase requires ATP.
Number 3: The answer is D; Arginase is located in the mitochondrion
Number 4: The answer is B; Ornithine produced in the cytosol must first cross the inner mitochondrial membrane into the mitochondrial matrix where it is carbamylated
