Answer 2

Answer:

Final answer:

The most likely mode of inheritance for each pedigree is:

Autosomal dominantAutosomal recessiveAutosomal recessiveX-linked recessiveAutosomal dominantAutosomal recessiveAutosomal dominantAutosomal recessive

Explanation:

Question 1:

The genetic disorder that exhibits reduced penetrance is Familial hypercholesterolemia. Reduced penetrance refers to the situation where individuals with the disease-causing mutation do not show any symptoms or have a milder form of the disorder. In Familial hypercholesterolemia, individuals with the mutation may have varying levels of high cholesterol, but not all of them will develop severe cardiovascular problems.

Question 2:

The true statement about X-linked dominantgenetic disorders is that affected fathers have 100 percent affected daughters. This means that if a father has an X-linked dominant disorder, all of his daughters will inherit the disorder.

Question 3:

In the case of a hemophilia carrier being married to a person with hemophilia, the expected outcome for their offspring is that all sons are affected and 50 percent of daughters are unaffected. Hemophilia is an X-linked recessive disorder, which means that it is more commonly seen in males. Sons inherit the affected X chromosome from their mother, while daughters have a 50% chance of inheriting the affected X chromosome.

Question 4:

In the case of autosomal recessive disorders, the true statement is that if both parents are affected, all children will be affected. Autosomal recessive disorders require both copies of a gene to be mutated in order for the disorder to be present. If both parents are carriers of the mutated gene, there is a 25% chance that each child will inherit two copies of the mutated gene and therefore be affected by the disorder.

Questions 5-8:

For each pedigree, the most likely mode of inheritance can be determined by analyzing the pattern of affected individuals in the family. The options are:

When blood supplies oxygen and food to a cell surface and these molecules diffuse across, we might expect some "resting time." However, if we inspected most cell membranes in a living human body, we would find a nearly continuous flow of substances back-and-forth across the plasma membrane. Which of the following is not a reason why? a) Cell metabolism is constantly using up oxygen and raw materials; this lowers their concentration so more will diffuse into the cell. b) Cell metabolism is constantly producing waste molecules; this increases their concentration so more will diffuse out of the cell. c) Cells produce useful secretions; this increases their concentration and more will diffuse out of the cell. d) Cell metabolism constantly produces carbon dioxide in respiration; this increases its concentration so more will diffuse out of the cell. e) Cells are living entities and in order to live can never "rest".

Horses and zebras can be bred to produce a zorse, which is sterile. Which is most likely the reason zebras and horses are considered separate species?

Answers

For an organism to be considered as same species, it is important that their progeny can mate and produce viable offspring for generations. In this case, the mating of zebra and horse does not produce a fertile offspring, hence, their offspring cannot produce future generation, so, they cannot considered to be in same species.

Moreover, there are difference in the number of chromosome in between zebra and horse, and the zorse's number of chromosome is also different from the zebra and horse. In a species, the number of chromosomes must be same, so, this is also a factor, why they are not considered as a same species.

Because they cannot breed together to provide fertile offspring. (If their children cannot have children they are most likely to be considered separate species)

Why is homeostasis important for survival

Answers

Homeostasis is maintaining an equilibrium or balance. Human bodies only function under very specific conditions, so it is important to maintain them through homeostasis. Otherwise, the proper conditions to function will be missing and we won't be able to function at all.
