Proteins scan chromosomes for damage during the G1 checkpoint. beginning of the synthesis phase. apoptosis phase. G2 checkpoint.
Gwar [14]

I assume that this is your question with the options:

Proteins scan chromosomes for damage during:

A) the G1 checkpoint

B) Beginning of the synthesis phase

C) Apoptosis phase

D) G2 checkpoint

E) Metaphase checkpoint.

Answer:

The answer is option A): G1 checkpoint.

Explanation:

During the internal checkpoints for regulation of a cell cycle, proteins usually scan chromosomes for damage to DNA and evaluate other external factors at the G1 checkpoint in order to ascertain whether conditions are inadequate. If conditions are inadequate and damages exist, cells will not be allowed to continue to the next phase.

Plasticity is most adaptive when the environment changes __________ throughout an organism's life.
Alexxandr [17]

Plasticity is most adaptive when the environment change <u>Slowly and predictably </u>throughout an organism's life.

The ability of individual genotypes to create various phenotypes when exposed to various environmental situations is known as phenotypic plasticity. Here, the emphasis is on the role of plasticity in evolution rather than the evolution of plasticity itself, i.e., the evolution of phenotypic traits and organismal variety through plasticity. Phenotypic plasticity is a crucial characteristic of developmental systems that enables the organism to deal with environmental variability and/or unpredictability, although its significance for adaptive evolution is still debated.

Round seeds are dominant over wrinkled seeds in
antoniya [11.8K]

Genotype - RR - 25%, Rr - 50%, rr - 25% (1:2:1)

Phenotype - Round seeds - 75%, Wrinkled seeds - 25% (3:1)

<h3>How explain your answer?</h3>

Let the letter "r" stand for the alleles, where R is round seeds and r is wrinkled seeds. A genotype is an individual's genes represented through alleles. Phenotypes are how the genes express themselves. In other words, genotypes will be written using letters, the alleles, and phenotypes will be the possible outcomes of the alleles.

Both of the parent seeds have the genotypes Rr and the phenotype of round seeds.

If you create punnet square (which had four boxes in total) 1 will have RR, 2 will have Rr, and 1 will have rr. These are the ratios for the genotypes. Each box represents 25%, so the percentages will be 25, 50, and 25. Finally, 3 of these boxes (RR and Rr) will result in round seeds because those are dominant. Only the genotype rr will result in wrinkled phenotype. Therefore, the ratio is 3:1 or 75% to 25%.

Thus, this could be the answer.
