Answer:

Xylem transports water, stomata take in carbon dioxide, and chlorophyll absorbs sunlight.

Explanation:

Photosynthesis is a vital process for the plant and is carried out thanks to xylem (it transports water), stomata (it captures CO2) and chlorophyll (it captures sunlight).

The transport of water in the plants is done mainly by the xylem route, this route is simpler when compared to the root, having less resistance, thus it has less pressure gradient necessary to transport water from the soil to the leaves. Xylem transport is much more efficient than cell-to-cell water transport. As we know, water is very important in the process of photosynthesis, so we can emphasize the importance of the xylem.

The main function of a stoma is to control the entry and exit of gases, so we can conclude that they are directly related to the performance of the photosynthesis process since CO2 is captured (important for photosynthesis to occur) and the release of oxygen. Stomata are found mainly in leaves and stems, being absent in roots.

Chlorophyll is the pigment responsible for capturing light and ensuring that photosynthetic organisms are able to produce their food through the process of photosynthesis, because it is able to capture sunlight. Therefore, it is essential for the maintenance of oxygen available on the planet. It is worth mentioning that, in addition, this pigment has commercial importance, being used, for example, as an antioxidant and coloring agent in foods.

OverLord2011 [107]

Answer:

1. Nucleotides

2. Amino acids

3. Amino acids

4. Glucose

Explanation:

All the above substance described are biomolecules. They are all polymers i.e. complex molecule bond together in a long repeating chain, made up of simpler subunits called monomers. The monomers of the different biomolecules outlined above are:

1. The nucleic acids, DNA and RNA carry genetic information and are made up of many NUCELEOTIDES. A nuceleotide is a chemical combination of a five carbon sugar (pentose), phosphate group and nitrogenous base. These nucleotides are arranged sequentially to form nucleic acids (RNA and DNA).

2. Myoglobin is a protein that binds oxygen molecules and is a polymer of AMINO ACIDS. Amino acids are the building blocks of proteins. They are arranged to form a 3D structure that determines the function of the protein.

3. Insulin is a protein hormone that regulates blood glucose levels and is a polymer of AMINO ACIDS. All proteins are made up of the amino acid but the protein's function is dependent on the 3D structure formed by the amino acid sequence.

4. Animals store energy in the form of glycogen, a carbohydrate made up of thousands of monosaccharide (GLUCOSE). Glycogen is a polysaccharide made up of many monosaccharide units. These units are glucose molecules that are multibranched to form the glycogen that stores mainly in the liver and muscles of animals.

The patient is receiving succinylcholine or commercially called anectine. 
Succinylcholine is a medication often used in the context of general anaesthesia and its main effect is general paralysis. The drug's mechanism of action includes the inhibition of the acetylcholine's action on skeletal muscles. This inhibition is caused by the binding of the drug on the nicotinic acetylcholine receptor and the depolarization of the muscle cell.

Una mujer lleva en uno de sus cromosomas X un gen letal recesivo (l), y en el otro alelo dominante normal (L). ¿Cuál es la propo
nlexa [21]

Question in English:

A female carries a recessive lethal gene (l) on one of her X chromosomes, and a normal dominant allele (L) on the other. What is the sex ratio to be expected in this woman's dependency if she marries a normal man?

Answer:

2/3 females

1/3 males

Explanation:

Females have two X chromosomes (XX) and males have an X and a Y chromosome (XY).

The genotype of the female is XLXl. The genotype of the male is XLY, since he is normal.

The possible genotypes are:

<u>                            XL                  Xl</u>

<u>XL</u>                     <em>XLXL             XLXl</em>

<u>Y</u>                       <em>XLY               </em><em>XlY</em>

<em />

All female offspring will be normal as they will always have one normal copy of the X chromosome from their father.

50% of the male offspring will be normal, but 50% will inherit the lethal gene from their mother.

Because the allele is lethal, that means XlY males will not be born.

That means 2/3 of the children will be females, and 1/3 will be males.
