Y-linked genes are linked to the Y chromosome. They are not as usual as the X-linked genes and can only be expressed by men or males. Sons' phenotype: 100% hairy ears. Daughters' phenotype: 100% not hairy ears.

<h3>What are sex-liked genes?</h3>

When talking about sex-linked genes, we refer to genes located in one of the sex chromosomes.

Being linked to one of the sex chromosomes means that these genes, and their corresponding alleles, will only be inherited together with the chromosome.

In general, genes are linked to the X chromosome. These are X-linked genes. In these cases, a male that inherits the X chromosome from a heterozygous female can express either the dominant or the recessive trait, depending on which allele it got from the mother.

However, some genes are linked to the Y chromosome and hence, inherited only by males or men. Traits coded by Y-linked genes will only be inherited by males.

In the exposed example, we are referring to an Y-linked gene, so it will only be inherited by sons and not daughters.

  • Expected phenotypes of the man's sons ⇒ 100% haired ears
  • Expected phenotypes of the man's daughter ⇒ 100% not haired ears

Which reactant of photosynthesis is also involved in climate change?
choli [55]

Answer:

B. Carbon dioxide

Explanation:

First of all, let’s write out the photosynthesis equation to identify the products and reactants.

6CO2 + 6H2O + energy —> C6H12O6 + 6H2O

In a chemical equation with the arrow pointing right, the reactants are on the left and the products on the right.

In photosynthesis, the reactants, carbon dioxide, water, and energy, react to form the products of glucose (sugar) and oxygen.

Now, let’s look at the answer choices. We can automatically eliminate choices A (oxygen) and D (sugar) because they are products.

We are left with B (carbon dioxide) and C (water). Water isn’t really considered a major contributor to climate change. Carbon dioxide is a greenhouse gas that traps heat in the atmosphere, causing climate change.

Therefore, the best answer choice is B. Carbon dioxide

List 3 ways muscle action may be determined.
In-s [12.5K]

Answer:

The muscle action can be determined by:

* Prime Movers and antagonist: Prime movers are also called the agonist, it is the muscle that provides the force that drives the action. Regarding to the antagonist muscle, it is the opposite to a prime mover as it provides resistance or reverse in a given movement. They are paired up on opposite sides of a joint.

* Synergists: There are one (or more) synergists involved in an action, the are muscles that help the prime mover when it is playing its role.

* Stabilizers: Their fuction is to keep bones immobile when it is needed. For example, the muscle of your back, they are stabilizers when the keep your posture sturdy.

Carl Woese distinguished between the members of the archaea and the bacteria using studies of their ribosomal RNA.

What is ribosomal RNA?

Ribosomal RNA (rRNA), a particle in cells that are sent out to the cytoplasm and is a part of the protein-creating organelle known as a ribosome, supports the change of courier RNA (mRNA) into protein. Moreover, ribosomal ribonucleic corrosive is a type of non-coding RNA that fills in as the primary structure block of ribosomes, which are essential for all cells. Protein combination is done by rRNA, a ribozyme, in ribosomes. In spite of never being converted into proteins, it makes up around 80% of cell RNA.

LET'S CHECK
Daniel [21]

Answer:

I.

4) The deoxygenated blood then travels through the veins and enters the right side of the heart.

1) The blood leaves the heart through the aorta.

2) The blood travels throughout the body via the arteries to the capillaries.

3) In the capillaries, the exchange of nutrients and gases occurs. Oxygen is absorbed by the cells while carbon dioxide is released into the blood.

II.

2) Exchange of gases happens as oxygen is received by the blood and carbon dioxide is released.

1) The deoxygenated blood flows from the right side of the heart to go to the lungs.

3) The oxygenated blood then returns to the left side of the heart.
