Albinism is a recessive trait. A man and woman are both of normal pigmentation, but both have one parent who is albino (without melanin pigmentation). What is the probability that their first child will be an albino

Answers

Answer 1

Answer:

use the generation tree starting by the grandparents as first generation and the parents as second generation until the child as third generation

Answer 2
The man and woman both have albino parents (aa) so one of their alleles will be for the albino trait (a). But since they both have normal pigmentation, their other allele must be for the dominant pigmented trait (A), making their genotypes heterozygous (Aa). If you make a quick punnet square with each of their genotypes on a side, there is a 1/4 or 25% chance that the combination of their alleles will result in an albino (aa) child.

Identify and name the cell organelle:
M- It allows transportation of materials in and out of plant cell.
Isn't the correct answer supposed to be cell membrane? Even though they mentioned in a plant cell.. Because the cell wall is completely permeable.. so it lets anything pass through.. but the cell membrane decides and allows materials to enter and exit the cell..
The teacher said the correct answer is cell wall though.. I would like to know your thoughts!

Answers

I believe that the correct answer would be cell wall. You said that the question referred to the cell organelle within a plant cell, which is why the cell wall is correct. The cell membrane is found in animal cells while the cell wall is found in plant cells.

Fish populations in some areas of the ocean have been exhausted by overfishing. This has caused ecosystems to become imbalanced and species to become endangered. The diagram below breaks the ocean's total fish population into three categories—species declining in population (overfished), species growing in population (moderately fished), and species with stable population (fully fished). The graph shows the percentage of the total fish population represented by each category for various years between 1974 to 2000. For example, in 1974, 51% of the population was fully fished, 39% was moderately fished, and 10% was overfished. What can be said about the trend in fish populations between 1974 and 2000? A. The percentage of the total fish population that is fully fished decreased by 18%. B. The percentage of the total fish population that is overfished increased by 18%. C.
