The question lacks the pedigree information. The pedigree has been attached below.

Answer:

AA/Aa.

Explanation:

The albino is a autosomal recessive trait means this trait will only be visible when the individual is homozygous recessive for the trait. The heterozygous individual acts as a carrier.

In the given, pedigree the parents are unaffected but one of their child is affected means that the parents are heterozygous for the trait. The croos between the parent Aa × Aa results in the progeny with genotype AA, Aa, Aa ( normal ) and aa (affected). The individual B-3 is unaffected and can have either genotype AA or Aa.

Thus, the answer is AA or Aa.

zhuklara [117]

Answer:

<em>It would cause a decrease in the carrying capacity of the owl population.</em>

Explanation:

The relationship between a predator and prey is unique. Both the population of a predator and prey gets affected if changes in one of them occur.

If mice migrated from the ecosystem, this will mean that there will b little food available for the owls on that ecosystem. As a result, they will compete for food. Some of them would get killed due to lack of food. Others will migrate to places where they can find food. Hence, the carrying capacity of the owl population would decrease.

The hypothalamus regulates the ________.
Tresset [83]

Answer:

c. pituitary gland

Explanation:

The hypo(below) thalamus is an almond size structure located superiorly to the brainstem. it is located below the thalamus. Hence the name hypothalamus.

It is primary function is is to control the body homeostatic functions of sleeping and waking up, sex, thirst and hunger etc.

It performs these roles by serving as the primary link of the nervous system with the endocrine system. Pituitary gland is an example of  endocrine gland that secrets many hormones. (they are called endocrine because the hormones are secreted directly into the blood streams.

<u>Its activities are controlled by the nervous stimulation from hypothalamus. Therefore the instructions to secretes certain hormones to the post and anterior part of the pituitary gland depends on the hypothalamus.</u>

Growth hormones, oestrogen, and thyroid are examples of hormones of the pituitary glands.

You add polynucleotide phosphorylase to a solution of ATP, GTP, and UTP. How many artificial mRNA 3 nucleotide codons would be p
zavuch27 [327]

Answer:

The correct answer is option D, that is, 27.

Explanation:

27 three-nucleotide codons would be possible when polynucleotide phosphorylase is supplemented to a solution of GTP, ATP, and UTP. As there are three nucleotides available, that is, guanine, adenine, and uracil and each codon comprise three nucleotides, thus, there would be a probability of (3)^3 codons, that is, 27.
