Huntington's disease, which causes degeneration of neurons, runs in Mark's family. Huntington's is a heritable, autosomal dominant genetic disease. In an autosomal dominant disease, only one abnormal allele is required to cause the disease in offspring. However, it is possible that not all offspring will receive the abnormal allele from an affected heterozygous parent. Family members that have the disease include Mark's maternal grandfather and Mark's maternal aunts. Mark's maternal grandmother does not have the disease. Because symptoms of Huntington's disease do not appear until later in life, genetic testing is necessary to determine whether a younger individual possesses the allele for the disease. These tests determined that Mark's mother does not carry the allele for Huntington's disease. Mark's paternal aunt suggested that Mark create a pedigree to track the disease in his family. Use the symbols provided to complete the pedigree. Each symbol may be used more than once.
Answer:
The correct answer is - maternal grandmother unaffected, maternal father affected, two maternal aunts affected, mother not affected and paternal side not affected so Mark is also not affected. (check the image)
Explanation:
As we know Mark's paternal grandparents do not have Huntington's disease. If the grandparents are normal the father and paternal aunt of Mark does not carry the disease allele therefore the symbols on the right represent Mark's paternal family.
We also know that the grandfather from the maternal side is affected and maternal aunts also have Huntington's disease, it is found out by the genetic testing that the mother is unaffected which means Mark will be unaffected as well as mother and father both are normal.

In 6 sentences, Cellular & Physical Comparison. Tell me the differences between plants and animals.
Answer:
Plants have either no or very basic ability to sense. Animals have a much more highly developed sensory and nervous system. Animals give off carbon dioxide which plants need to make food and take in oxygen which they need to breathe. Plants cells have cell walls and other structures differ from those of animals.

How many stops can you potentially make on your trip? Why?
The island spotted skunk and the island fox are both predators of the island
deer mouse (the prey). How could these two predators establish different
niches and still prey upon island deer mice? *
A. the island spotted skunk hunts at different times than the island fox
B. the island spotted skunk hunts in the same area as the island fox
C. the island fox eats only cherries instead of deer mice
D. the island deer mice swim to a different island to avoid predators
Answer:
I think the answer is A because if they hunt at the same time they will kill themselves

I put a picture does anyone know the answer to that
Answer:
C- All members of the population are genetically similar and are less likely to survive environmental change.
Explanation:
In asexual reproduction, there is no diversity since the offspring gets all their genes from their parent. That being said, they won't be able to inherit traits that would help them survive in a changing environment since there is no diversity of traits that would help them in other environments.

does coal releases carbon dioxide into the atmosphere?
Answer:
yes
Explanation:

If a flower is wilting, which structure inside its cells lacks water?
vacuole
cell wall
carpel
chloroplast
Answer:
Vacuole
Explanation:
The central vacuole stores water in the cell and helps maintain water pressure, or turgor pressure, within the cell. The plant wilts because the central vacuole is empty and the cell is partially collapsed. Once the plant is watered and the central vacuole is full again, the plant will return to its normal position and appearance.
