Answer:

they have a 25% chance of having a son with hemophilia and a 25% chance of having a daughter with it.

Explanation:

Hemophilia is an linked gene so when you create a punnet square those are the result you should receive.

When not enough oxygen is available to cells during rigorous exercise, muscle cells must convert pyruvate to __________ to gener

Kipish [7]

The correct answer is: A) lactic acid.

During the exercise, muscle cells use anaerobic respiration in order to make enough energy in the form of ATP. Anaerobic respiration doesn’t require oxygen, but glucose is broken down to produce energy. Glucose is broken down to pyruvate in the process called glycolysis. Next step is convert of pyruvate into lactic acid (or lactate).

During the exercise, the oxygen level in muscle cells decreases, which results in anaerobic respiration of the cells.

The pedigree below tracks the presence of dimples through a family's generation. Having dimples is an autosomal dominant trait.

yulyashka [42]

A pedigree is a representation of a family history tracking a trait. The graph shows the inheritance pattern of the trait and its expression through several generations.

<h3>What is an autosomal dominant trait?</h3>

The autosomal dominant trait is the characteristic that is coded by a gene located in an autosomal chromosome (this is, not a sexual chromosome).

This trait is dominant because it is coded by the dominant allele, meaning that the recessive allele codes for the absence of dimples. The presence of only one dominant allele in the genotype is enough for the idividual to express dimples.

<u> Genotype Phenotype </u>

DD, Homozygous dominant Dimples

Dd, Heterozygous Dimples

dd, Homozygous recessive No Dimples

<h3>What is a pedigree?</h3>

The pedigree is the representation of a family history conserning a certain trait. In this case, dimples.

The pedigree shows the expression -and inheritance pattern- of the trait through several generations.

To correctly interpret a pedigree, we need to know that

Family members

→ Individuals are represented with geometrical figures.

→ Males are squares

→ Females are circles

Trait/Phenotype

→ Healthy/normal/not affected individuals are represented with empty figures

→ Affected/mutated individuals are represented with solid black figures

Generations

→ Each file is represented with a roman number, indicating the Generation.

Here we will assume that

Individuals represented with solid figures express dimples -shaded individuals-. They can be either DD or Dd. This is because dimples is not usuall.

Individuals with no dimples are represented with empty figures and are dd.

According to the provided pedigree,

I-1 ⇒ man DD or Dd

I-2 ⇒ woman dd

II-1 ⇒ man Dd or DD

II-2 ⇒ woman dd

II - 5 ⇒ woman dd

III - 1 ⇒ man Dd

III- 2 ⇒ woman dd

III - 6 ⇒ woman dd

Since this pedigree does not specify the relationship between individuals, I can not answer the question based on it. So, I will attach another tree to specify genotypes.

I advise you study this new example, and then follow the same reasoning to choose the correct individual according to you pedigree.

As a mollusk the animal probably has

andrezito [222]

As a mollusc, the animal probably has a mantle and a radula.

Molluscs are aquatic species that belong to the phylum of Mollusca. Mollusca is one of the biggest and most diverse phyla of the sea.

A mantle is a term that describes the fold in their body which secretes the hard protective shell of their body. A radula is a toothed structure (similar to the tongue) used to collect food.

2.The death of individuals reduces population size. If births outnumber deaths, the population grows.

valentinak56 [21]

Answer:

True

Explanation:

This would be like a birth to death ratio. If you have more deaths than births your population would decrease. See a similarity?

Which of the following is not a function of the skeletal system? (a) (a) production of blood cells, (b) storage minerals, (c) st

brilliants [131]

Answer:

C is the correct option. Storage of carbohydrates is not a function of the skeletal system.

Explanation:

Option A is correct because the skeletal system has parts like the red bone marrow in which red blood cells and white blood cells are produced.

Option B is correct because the bones store minerals like calcium and phosphorus.

Option D is correct because the major function of the skeletal system is to provide support and protect the vital organs of the body.

The skeletal system is not involved in storing carbohydrates. Hence, all statements are true except for statement C.
