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
Answer:
individuals do not evolve, as each individual's genes do not change, and evolution is defined as the change in allele frequencies over time.
Explanation:
Sentence Correction: In which part of the cell is the majority of the energy released from the breakdown of glucose?
nucleus
mitochondrion
cytoplasm
plasma membrane
Answer: <em>The answer is mitochondrion.</em>
Explanation: <em>The reason the is the correct answer is because, there are the Locations of Cellular Respiration which occurs in two stages.</em>
<em>First stange - cytoplasm</em>
<em>Second stage - mitochondrion</em>
<em>So as we can see, mitochondrion is the Second stage which is the correct answer because the majority of the energy released from the breakdown of glucose.</em>

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!
Answer:
Abnormal BRCA1 and BRCA2 genes are found in 5% to 10% of all breast cancer cases in the United States. A study found that women with an abnormal BRCA1 gene had a worse prognosis than women with an abnormal BRCA2 gene 5 years after diagnosis.
