Answer:
D. astigmatism
Explanation:
Astigmatism is an imperfection in the curvature of the eye. Most of the focusing power in the eye occurs along the frontal surface called the cornea. The next structure involved in focusing is the lens, which lies behind the iris inside the eye.
The ideal cornea has a symmetrically curved surface, like a basketball. Astigmatism is caused by a cornea or lens with a curve that is not symmetrical. As a result, people with astigmatism may have distorted or blurred vision.
Astigmatism can occur in families and in most cases is associated with other refractive problems such as nearsightedness or farsightedness. It may also increase over time due to age.
Answer:
La energía del organismo vivo no se puede perder ni ganar del entorno externo.
Explanation:
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.
