Questions 5-8: The most likely mode of inheritance for each pedigree cannot be determined without reviewing the attached powerpoint presentation.

Explanation:

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:

Why has groundwater use increased?a.the total amount of freshwater has decreased
b.more of the available freshwater is stored in glaciers and icecaps
c.governments have banned the use of freshwater in rivers and springs
d.the demand for freshwater has increased due to population growth

Answers

Groundwater use has increased because D. the demand for freshwater has increased due to population growth. Obviously, the more people there are, the more water is going to be used, because all people in the world need water in order to survive. So they need to find ways to obtain more water, which is where groundwater comes into play.

Forces of attraction between particles is the SMALLEST in gas
solid and liquid
solid

Answers

Answer:

gas

Explanation:

In gas there are weak attraction forces present between the particles.

Properties of gases:

Molecule of gases randomly move everywhere and occupy all available space.

Gases don't have definite volume and shape and take the shape and volume of container in which it present.

Their densities are very low as compared to the liquid and solids.

Gas molecules are at long distance from each other therefore by applying pressure gases can be compressed.

The very weak inter molecular forces are present between gas molecules.

Properties of Liquid:

Liquid have definite volume but don,t have definite shape.

Their densities are high as compared to the gases but low as compared to the solids.

In liquid, molecules are close to each other and have greater inter molecular forces as compared to the gas molecules.

Properties of solids:

Solids have definite volume and shape.

In solids molecules are tightly pack and very close to each other.

Their melting and boiling point are every high.

The densities of solids are also very high as compared to the liquid and gas.

There are very strong inter molecular forces are present between solid molecules.
