1. The percent probability that the first child of the couple will have Huntington's disease is 50%
2. The percent probability that four of the seven children will have Huntington's disease is 6.25%
<h3>Genetical probabilities</h3>
The disease is autosomal dominant. Only one dominant allele is needed for the disease to be manifested.
The husband is Hh and the wife is hh.
Hh x hh
Hh Hh hh hh
Hh (affected) = 1/2
hh (unaffected) = 1/2
1. Probability that the first child of this couple will have Huntington's disease is the same as the probability of having the disease. Thus, it is 1/2 (50%)
2. Probability that four of the seven children will have Huntington's disease is the same as the probability of having the disease in 4 places.
1/2 x 1/2 x 1/2 x 1/2 = 1/16 or 6.25%

Answer:
Same number of neutrons.
Explanation:
What defines an atom as a certain element is the number of neutros in its nucleus. Some atoms have a different number of neutrons, but are still the same element, we call these variants "isotopes".

Answer:
The frequency would be stable.
Explanation:
Based on the most common symptoms of cystic fibrosis, the disease only appears on adults and elderly. This feature means that the frequency of the disease would not drop or raise because they would still reproduce and pass the allele from generation to the next, maintaining the frequency stable.
The four main biological macromolecules are lipids, proteins, nucleic acids, and carbohydrates. The term "macronutrient" particularly refers to the macromolecules that give the organism its nutritional energy.
<h3>What are biological macromolecules?</h3>
Large, naturally occurring cellular components known as biological macromolecules perform a variety of vital tasks for the development and survival of living things. There are four significant categories of biological macromolecules: lipids, proteins, nucleic acids, and carbohydrates.
Proteins, nucleic acids, and polysaccharides are typical examples of macromolecules.
Macromolecules are enormous molecules that fill a cell and give it vital life-sustaining activities. Macromolecules, for instance, offer structural support, serve as a reservoir for stored energy, have the capacity to store and retrieve genetic information, and can speed up biological operations.
