Answer:

The transfer of pollen to a stigma, ovule, flower, or plant to allow fertilization. It can be transferred by things that feed from what has pollen. Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species.

True or False: The oxidation process occurring in the liver rids the bloodstream of 32% of the alcohol present.

murzikaleks [220]

Answer:

False

Explanation:

Oxidation process occurring in liver rids bloodstream of not 32% of alcohol present.

Once the alcohol enters the body, 5 percent of it is excreted in the form of the urine and another 5 percent is eliminated from the body by exhaling and the rest of the alcohol is converted to acetic acid by oxidation.

Thus,

Oxidation process occurring in liver rids bloodstream of 90% of alcohol present.

Analyze the result of a cross between two organisms that are both heterozygous for two different genes (AaBb) use a Punnett squa

krok68 [10]

(1) All the genotypes are as follows: AABB, AaBB, AABb, AaBb, aaBB, aaBb, AAbb, Aabb, aabb.

(2) Assuming that Aa is dominant and Bb is recessive, there will be 9 phenotypes with both A and B allele dominant (i.e. AaBb, AABb); there will be 3 phenotypes with just the A allele dominant (i.e. Aabb, AAbb); there will be 3 phenotypes with just the B allele dominant (i.e. aaBb, aaBB); and there will be 1 phenotype with both alleles recessive (i.e. aabb). The phenotypic ratio in this case is 9:3:3:1.

(3) The probability of producing an offspring with the aabb genotype is 1/16 or 6%.
