Aleksandr [31]

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

Algae are important in the formation of coral reefs.<br> Brown<br> Red<br> Fire<br> Golden-brown
Sliva [168]

Answer:

Red algae

Explanation:

Coral reefs are the structure which are one of the some most important underwater ecosystems of the world. They are characterized by the formation of roof-building corals which are basically the colonies of dead or living polyps(corals) attached together through deposition of calcium carbonate.

Red algae has an important role in the formation of coral reefs  because their thread like structure traps the particles present in the sand of water which ultimately gives the algae a mechanical support for their growth as well as the formation of coral reefs.

Hope it helps!
