Answer:
Option. A) 12
Explanation:
An organism with 24 chromosomes in each body cell will produce sex cells with 12 chromosomes. The chromosome number is half because meiosis occurs in sex cells in which parent cell is divided into four daughter cells having half number of chromosome i. e. haploid. So the parent cell has 24 chromosome when division occurs, the number of chromosome becomes half i. e. 12.
Explanation:
In the given question, the digestion of monosaccharides has been discussed and the steps of digestion in the digestive system are:
1. The digestion of carbohydrates begins in the mouth where amylase breaks down the starch.
2. The sugars are not completely digested in the mouth therefore they travel from mouth to the stomach.
3. In the stomach, there are no enzymes to digest the sugars.
4. Then, food enters the intestine where intestinal secretions breakdown the sugars.
5. The intestinal juice breaks down the oligosaccharides into diassacharides and these disaccharides are further broken down by maltase, sucrase and lactase.
6. After this, the monosaccharides are formed and these are easily absorbed into the bloodstream.
7. Pancreatic amylase breaks down starch into monosaccharides.
This completes the digestion of the carbohydrates.
During diffusion molecules move from a higher concentration to a lower concentration. It is how the molecules move in and out of cells. (D)

Answer:
B)TAT becomes TAC
Explanation:
since thymine(T) pairs with adenine(A), thymine(T) is replaced with uracil(U) in the RNA and guanine(G) pairs with cytosine(C)
we can find the complementary codons for each strand
the codon for TAT is AUA which codes for methionine
the codon for TAC is AUG which also codes for methionine
that means the phenotype (methionine)remains unchanged for different genotypes(TAT and TAC)
