The different blood vessels; First, Arteries that carry the blood from the heart. Then, the Capillaries which allow an exchange of water and chemicals throughout the blood and the tissues. Finally, Veins that carry blood from the capillaries to the heart.
The correct answer is option B, 50%
Let us take the following case:
Genotype of heterozygous parent - (Aa)
Genotype of homozygous parent – (aa)
Allele I - (Aa)
Allele II – (aa)
The cross between the two is shown below:
Aa X aa
Aa, Aa, aa, aa
There are 50 % Aa, and 50 % aa allele.
Thus, the allele I (Aa) is 50 %.
D. Genetic Engineering
Doesn’t matter if it takes hundreds of years or a couple weeks, if there is an intent to alter the genes of an organism to select for desired traits, it is genetic engineering.
The two processes are similar in that they both produce energy, albeit in two different forms. They are different in that photosynthesis assembles the glucose molecule, while cellular respiration takes it apart
