Answer: Enviroment
Explanation: Environmental factors or conditions influences growth, health
(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%.
Answer:
Natural Gas
Petroleum
Coal
Explanation:
1) Ethanol is not a fossil fuel
2) 94% of ethanol is produced from the starch in corn grain
3) fossil fuel definition: a natural fuel such as coal or gas, formed in the geological past from the remains of living organisms.
4) fossil fuels are usually found in the earth's crust... not made from corn grain
Answer:
The correct answer is D its loss causes retinoblastoma a rare childhood cancer of the eye.
Explanation:
p53 is one of the most important tumor suppressor protein.It is named so because it has a molecular weight of 53 kd.p53 is encodes by TP53 gene.p53 play a significant role during apoptosis or programmed cell death.
But the mutation in p53 does not cause retinoblastoma.Retinoblastoma is caused due to mutation in Retinoblastoma tumor suppressor protein.This disease is formed when both the allele of the retinoblatoma gene gets mutated.
