Answer:
3 long tails : 1 short tail
Explanation:
This question involves a single gene coding for tail length in mice. The allele for long tail (T) is dominant over the allele for short tail (t). This means that an heterozygous mice will possess the long tail length.
According to this question, in a cross between two hybrid or heterozygote mice i.e. Tt × Tt, the following gametes will be produced by each parent:
Tt - T and t
Using these gametes in a punnet square (see attached image), the following will be produced: TT, Tt, Tt and tt.
Offsprings with genotype TT, Tt and Tt will have a LONG TAIL while genotype tt will have a SHORT TAIL. Hence, the phenotypic ratio will be 3 long tails : 1 short tail.
The first stage of cellular respiration is most commonly referred to as glycolysis!
Protozoa are Eukaryotic organisms, they show animal/plant like behaviors. Bacteria are prokaryotic, very tiny simple single celled organisms with no nucleus or mitochondria.
Answer:
Option B, It's complicated; we evolved from living apes but not specifically chimpanzees
Explanation:
Humans resembles very closely with the Apes and thus it is believed that the closest ancestors to humans is ape. Humans have not originated from chimpanzees, gorillas or even apes. There are several controversies associated with the evolution of humans. There have been several geological time gaps during the evolution of humans. Also though humans have not evolved from the Apes , they share several primate characteristics with them.
Hence, option B is correct
The correct answer is C. <span>a density-independent limiting factor
When bird populations sometimes decrease in areas due to wind farms, this occurrence is known as a density-independent limiting factor because it is not related so much to density.</span>
