Answer:
Option B, Rr pp × rr Pp
Explanation:
Given
Walnut Comb is produces when one dominant allele R is present at one gene locus and at least one dominant allele P is present at a second gene locus - R* P*
Rose Comb - at least one dominant allele is present at the first locus and two recessive alleles are present at the second locus - R* pp
Pea comb - two recessive alleles are present at the first locus and at least one dominant allele is present at the second - rr P*
Single comb - two recessive alleles are present at the first and the second locus - rrpp
Parent are rose combed and pea combed
For being rose genotype must be R* pp
and for being pea combed genotype must be rr P*
Rr pp x rr Pp
will produce
Walnut comb with genotype Rr Pp
Single comb with genotype rrpp
and pea comb with genotype rrPp
Hence, option B is correct
A small town is located near a body of water and enjoys cooler temperatures than other areas in the same climate zone. This is an example of a microclimate
Explanation:
- The microclimate is nothing but experiencing a different temperature, which is restricted to a certain area only. It might be experiencing a lower temperature in comparison with the surrounding regions.
- The dry climate is experiencing a very high temperature and polar climate is nothing but a region where there are no warm summers and the temperature would be less than 10 degree Celsius.
- Climate zones are characterized by distinct parameters and these are found near the poles
The answer is C. Organelles
Food web stability is most dependent on the number of connections among species.
