Answer: Eight (8) different kinds of gametes can be produced by an individual with the genotype AABbCCddEeFf.
Explanation: Total number of gametes that can be formed can be determined by the formula 2^n where n is the number of heterozygous loci.
The heterozygous loci in the genotype AABbCCddEeFf are Bb Ee and Ff; n = 3
Therefore, 2^n = 2^3 = 2 x 2 x 2 = 8.
Answer:
The correct answer is - Take blood samples and use DNA evidence to determine a more complete phylogenetic tree
.
Explanation:
Scientists could not use DNA evidences to make a complete phylogenetic tree of Icthyosaur as there are no blood samples or other DNA molecules to create DNA printing or mapping to create phylogeny with the modern dolphins. They only can be make similarities based on the morphological characteristics of these two groups.
Thus, the correct answer is - Take blood samples and use DNA evidence to determine a more complete phylogenetic tree
.
Answer: enable them to imprint on the facility
Explanation:
The addition of the chemicals to the river will help the fishes to recognize that this was their native habitat where they got birth and grew. This will act as a imprint formed by the facility which will help the fishes to recognize the water of the facility. This will help in increasing the number of fishes which return back to the facility.
Answer:
Car pollutants cause immediate and long-term effects on the environment.
Explanation:
Car exhausts emit a wide range of gases and solid matter, causing global warming, acid rain, and harming the environment and the health of living organisms, like humans.
Long-term exposure to polluted air can have permanent health effects such as:
- Accelerated aging of the lungs.
- Loss of lung capacity and decreased lung function.
- Development of diseases such as asthma, bronchitis, emphysema, and possibly cancer.
