Answer:
The song Sparrow can be best classified as R-strategist and generalist
Explanation:
A generalist is an organism that can adapt to different habitats and can consume different resources.
As written in the description, the song Sparrow show are able to survive in a number of different habitats and they can feed on many preys hence, they are generalists.
R- strategist organisms can be described as the organisms which produce wide number of offsprings and have a short life span. They might produce enormous number of eggs but very little of them will be able to survive.
As the song Sparrow can produce several broods in a year hence, it is an R-strategist.
Answer:
Phenotypes of offsprings: Type A, Type B
Explanation:
This question involves a single gene for blood group in humans. The ABO blood group system consist of three alleles: A, B, and O. A and B are dominant over O but co-dominant to one another.
If a woman with type O blood (OO) has a child with a male with type AB blood (AB) i.e OO × AB, the following gametes will be produced by each parent:
OO - O
AB - A and B
Using these gametes in a punnet square (see attached image), the offsprings with the following genotyoes will be produced: AO (2), BO (2)
AO - phenotypically type A
BO - phenotypically type B
Hence, a type A and type B blood group offsprings will be produced.
Answer:
b
Explanation:
<em>Let the wild type trait, the silver-white, be represented by </em><em>A</em><em> allele and the mutant trait, the golden color, be represented by </em><em>a</em><em> allele.</em>
Heterozygous wild-type male fish would be Aa
Golden female fish would be aa
Aa x aa
Aa Aa aa aa
2/4 Aa = silver-white
2/4 aa = golden color
<em>Hence, the percent likelihood of golden offspring is </em><em>2/4 or 50%.</em>
The correct option is b.
Answer;
-Skin cells do not need crystallin for their function.
-Skin cells have the crystallin gene but do not express it.
Explanation;
-The crystallin proteins are water-soluble structural proteins that occur in high concentration in the cytoplasm of eye lens fibre cells. It has also been identified in other places such as the heart, and in aggressive breast cancer tumors.
-The main function of crystallins at least in the lens of the eye is probably to increase the refractive index while not obstructing light. The skin cell does not make crystallin protein because the skin cells do not need crystallin for their function and also they have the crystallin gene but do not express it.
An undersea volcanic formation that does not rise at least 1000 meters above surrounding sea floor is called a <span>seamount.</span>
