The expected percent of offspring of the Scottish fold with folded ears is 75%.

The Scottish Fold is a breed of domestic cat with a natural dominant gene mutation that affects cartilage throughout the body, causing the ears to "fold", bending forward and down towards the front of the head, which gives the cat what is often described as an "owl-like" appearance.

The fold is inherited as an autosomal dominant trait. This means that a cat with folded ears may have either one (heterozygous) or two copies (homozygous) of the dominant fold gene (Fd). A cat with normal ears should have two copies of the normal gene (fd).

If a cat that is heterozygous for the fold allele mates with a cat that is homozygous for the fold allele, the expected percent of offspring that will have each characteristic are:

Therefore, the expected percent of offspring with folded ears is 75%.

Answer:

B. It stores glucose in the body of animals.

The main role of the carbohydrate glycogen is that it stores glucose in the body of animals. So the correct option is B.

Most of the carbohydrates that are consumed by a person from the foods are broken down. After being broken down, it gets converted to a sugar called glucose which is a monosaccharide.

The main source of fuel for our cells is glucose. But, sometimes, some extra glucose is present in our blood Which doesn't need to be used for the production of energy at the time.

Thus, it is stored in the liver and muscles in the form of glycogen. Glycogen is the stored form of glucose and is made up of many connected molecules of glucose molecules.

It is utilized by when a quick boost of energy is required or when enough glucose is not being produced from the food. In this case, glycogen is broken down to glucose which is released into the bloodstream and utilized as fuel for the cells.

Therefore the correct option is B.

These changes had a major impact on the Galapagos Islands. The increased temperatures led to more frequent and intense droughts, causing a decrease in vegetation and an increase in the spread of invasive species.

What is temperatures ?

Temperatures refer to a measure of the amount of heat energy in a given environment. It is measured in degrees Celsius (°C) or Fahrenheit (°F). Temperature can affect many factors in an environment,

such as the rate at which reactions occur, the rate of evaporation, and the ability of organisms to survive. Changes in temperature can affect weather patterns, ocean currents, and the growth of plants and animals.

Answer:

A

Explanation:

because fuels are used to produce electricity from solar energy

The frequency of the recessive allele would be 0.55, that of the dominant allele would be 0.45, and that of the heterozygous individuals would be 0.495

Recall that for a population in Hardy-Weinberg equilibrium:

p2 + 2pq + q2 = 1

Also, p + q = 1

Where:

p = frequency of the dominant allele in the population

q = frequency of the recessive allele in the population

p2 = percentage of homzygous dominant individuals

q2 = percentage of homzygous recessive individuals

2pq = percentage of heterozygous individuals

In this case, the percentage of homzygous recessive individuals can be calculated as:

Homzygous recessive = those that could not taste PTC = 65/215

q2 = 65/215 = 0.302

    q = 0.55

Since p + q = 1

           p = 1 - 0.55

                   = 0.45

The frequency of the heterozygous individuals = 2pq

                      = 2 x 0.45 x 0.55

                        = 0.495

Explanation:

Answer:

The water vapor content in the atmosphere is typically recorded using a measurement called relative humidity, which represents the amount of water vapor present in the air relative to the maximum amount the air could hold at a given temperature. Therefore, if two locations have different water vapor content in the atmosphere, it is likely that they would have different relative humidity readings.

For example, if one location has a higher water vapor content in the air, it would have a higher relative humidity measurement than a location with a lower water vapor content. Conversely, if one location has a lower water vapor content in the air, it would have a lower relative humidity measurement than a location with a higher water vapor content.

It is important to note that other factors can also influence relative humidity measurements, such as temperature and atmospheric pressure, so a direct comparison of relative humidity readings between two locations should take these factors into account.

An oxidation-reduction (redox) is a form of chemical reaction during which electrons are swapped among three varieties. Any chemical process when the oxidation state of a molecule, atom, or ion shifts by transferring or losing an electron is an oxidation-reduction reaction.

Any formed from the reaction under which the oxidation percentage of an able to participate chemical species variations is known to as an oxidation-reduction reaction. Oxidation is a chemical process. It is viewed as the technique through which particles or atom groups end up losing electrons. Another meaning of oxidation is that when a substance absorbs or releases hydrogen. Whenever these events happen, oxidation occurs. A substance gains one or more electrons during the reduction process. An oxygen atom or electronegative atoms are lost. A hydrogen atom or electrophilic atoms are obtained.

Answer:

A)Como Juan nació normal (aa) la única posibilidad para que Santiago su hijo naciera con polidactilia era que su madre lo fuera también.

Explanation:

La polidactilia es una malformación causada por un alelo dominante asociada con al aparición de más de 5 dedos en cada pie o más de 5 dedos cada mano. Un alelo dominante es una variante génica capaz de enmascarar la expresión de un alelo recesivo en individuos heterocigotos, es decir, en individuos portadores de una copia del alelo dominante y una copia del alelo recesivo para un gen en particular. De este modo, un alelo dominante es por definición aquel que será expresado en el fenotipo, con lo cual el único modo en el cual Santiago sea portador del alelo dominante causante del rasgo "polidactilia" es que él lo haya heredado, ya sea del padre o de la madre (es importante aclarar que también el alelo dominante puede haber surgido por mutación en la línea germinal). En este caso sabemos de acuerdo al enunciado que el padre de Santiago no tiene polidactilia y por lo tanto no es portador del alelo dominante, con lo cual se espera que Santiago haya heredado esta condición de su madre.
