Answer:

Digestion works by moving food through the GI tract. Digestion begins in the mouth with chewing and ends in the small intestine. As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules. The body then absorbs these smaller molecules through the walls of the small intestine into the bloodstream, which delivers them to the rest of the body. Waste products of digestion pass through the large intestine and out of the body as a solid matter called stool.

Table below shows the parts of the digestive process performed by each digestive organ, including movement of food, type of digestive juice used, and food particles broken down by that organ.

Explain what terms in the Hardy-Weinberg equation give: allele frequencies (dominant allele, recessive allele, etc.) each genoty

zysi [14]

Answer:

Explanation:

Hardy Weinberg equation is presented below and describes that in a population the frequency of alleles ad genotypes will remain static or the same in the absence of evolutionary disturbances such as mutation, migration ( gene flow), natural selection and with the population large and random mating

p² +2pq + q²

where p represents the frequency of the dominant alleles

q represent the frequency of the recessive alleles

p² represent the frequency of the dominant homozygous genotype

q² represent the frequency of the recessive homozygous genotype

2pq represent the frequency of the heterozygous genotype

q² also represent the frequency of the recessive phenotype

(p² + 2pq) represent the frequency of the dominant phenotype

A researcher was performing a test to check the effect of induced point mutation. But the experimental mouse could not survive.

miv72 [106K]

A researcher was performing a test to check the effect of induced point mutation. But the experimental mouse could not survive. The reason for this is a lethal mutation. This is a mutation in which the effects can result in the death of an organism carrying the mutation. It is also known as lethal factor or lethal gene.

I hope it helps, Regards.

Explain how conversion of a normal somatic cell into a malignant one requires multiple mutations.

MAXImum [283]

Answer:

Mutation is the alteration in the DNA base sequence in an organism.it may be due to chemical or environmental effect on the somatic cells..

Generally ,most cancers are caused by mutation in DNA components of abnormal cells.

Basically proto-oncogene is responsible for cell growth and cell division before mitosis in normal healthy cells;thus its codes for the main protein specific for cellular functions in normal cells. Therefore for mutation to occur mutations in mutiple genes is important. .

Basically 2 p53 alleles must be mutated,

2 BRCA1 allele must be mutated,

and 1 mutated allele of HER2 mus be mutated.

All these multiple mutations in these genes are needed.
