Answer: '' any of the answers are correct'' . In cells, genes are segments of DNA that code for proteins; not sugars or complex carbohydrates, or lipids, but proteins. The code in the sequence of nucleotides in a gene specifies the sequence of nucleotides in messenger RNA which in turn specifies the sequence of amino acids in a protein. The sequence is variable because of mutations which can change the sequence of amino acids in the protein coded for by that gene. Therefore, in evolution, a change in a single code for a single amino acid may have an effect on individual survival. Proteins carry out many functions in a cell such as any of the answers are correct. ♡ hope this helps ♡.
Answer:
The correct answer is option d) age of either or both parents.
Explanation:
Genetic variation is the difference in nucleotide sequences between individuals organisms within a particular population. Variation can occur either in germ cells that are sperm and egg or in somatic cells or in both.
Random fertilization of egg and sperm can lead to genetic variation is every germ cell has a different set of chromosomes. Independent assortment of chromosomes is also the same as random fertilization as it is also random. Crossing over of homologous chromosomes is one of a major source of the genetic variation as it forms a new set of chromosomes.
Thus, the correct answer is option D) age of either or both parents.

Answer;
Husk.
Whole-grain flour contains all parts of the grain with the exception of the husk.
Explanation;
Whole grain foods contains the following parts; Bran, Endosperm and Germ, originally present before processing.
Refined grains on the other hand are mainly composed of only endosperm portion of the grain. Milling process removes bran and some also removes germ, along with the majority of fiber, vitamins, minerals, antioxidants and phytochemicals.
