Answer:
<em>The correct option is B) the total variety of organisms on Earth</em>
Explanation:
Biodiversity can be described as the diversity or variety of life present on Earth. The variety of plants and animals which are located in different habitats make up the biodiversity. Biodiversity is the reason that different variety exist between members of a species. Biodiversity tends to favour those organisms which are better adapted to live in an environment. These organisms tend to pass on their characteristics to their offsprings and become more in number.
Answer:
The parent with black fur had genotype Bb.
Explanation:
White fur is recessive in mice, so a mouse with white fur has to have two alleles of the white fur gene (bb). Black fur is dominant to white fur, so a mouse with black fur only needs one allele of the black fur gene (BB or Bb). In order for a black mouse and a white mouse to produce white offspring, the black parent has to have an allele for the white fur gene (Bb).
ANSWER:
Dark coloured fish living in lake B while bright colored fish living in lake A, each group of fush have same gene fool where random mating is possible and chances of speciation is null. However, when migration of one group of fish occur toward another group of fish then gene flow also occured. This result into breeding amongst members of two different groups. So the chances for speciation increase, and it is possible that with the passage of time new species may develop.
The method to creating flowers would be a matter of sexual reproduction.
Answer:
A. Antibodies to A and B are present in the red cells.
Explanation:
AB positive is a blood type with the presence of A and B antibodies in the red blood cells, with the absence of A and B antigens. This blood type is referred to as the “universal recipient” because individuals who are AB positive can receive from all blood types including O, A and B. AB positive is only able to donate blood to patients who are AB positive AB is referred to the rarest blood type.
Therefore Fred's red blood cells have A and B antibodies.
