Answer:

During the prophase of meiosis I, the double-chromatid homologous pairs of chromosomes cross over with each other and often exchange chromosome segments. This recombination creates genetic diversity by allowing genes from each parent to intermix, resulting in chromosomes with a different genetic complement.

Explanation:

Through a process known as crossing over, which enables new combinations of variants to appear in the gene pool, meiosis promotes genetic diversity.

During the prophase of meiosis I, homozygous chromosomes are next to one another and exchange genetic material.

There could be a heterozygous state for a gene if two distinct alleles are present on the same genetic locus on homologous chromosomes. (For instance, an allele for antigen A on one chromosome and an allele for antigen B on another; both are used to determine the ABO blood group.)

Numerous genes are linearly ordered on chromosomes; as a result, some of them may still be heterozygous. (The same person may be heterozygous for the ABO blood group, iris color, and sickle cell anemia).

Therefore, Through a process known as crossing over, which enables new combinations of variants to appear in the gene pool, meiosis promotes genetic diversity.

Answer:

the air

Explanation:

Plants get the carbon from the air which are needed to make the glucose molecules during the process of photosynthesis in plants. Thus, the correct option is B.

Photosynthesis is the process of formation of carbohydrate (sugar) in the green leaves of plants. This process takes place in the presence of light. In this process, the light energy (solar radiation) is trapped in the chlorophyll pigment present in the green leaves of plants, this energy is converted into chemical energy in the form of glucose (carbohydrate) which is used by the plants in various processes.

The reaction includes the reaction between carbon dioxide and water molecules which are present in the air to produce glucose and oxygen gas which are consumed as food and in the process of respiration.

Therefore, the correct option is B.

Answer: rough endoplasmic reticulum

Explanation:

Answer:

Plants need water, so that their guard cells can fill up and become turgid which would allow the stomata to open and gas to exchange. If there is not much water, not much gas exchange can occur hence not much Carbon dioxide can be taken in.

Explanation:

Plants require water for the process of photosynthesis. Plants need water so that their guard cells can fill up and become turgid. This allows the exchange of gases in the stomata.

During photosynthesis, the plants take in carbon dioxide and water molecules from the air and soil particles. Within the plant cell, this water is oxidized to generate oxygen gas, meaning that it loses electrons, while the carbon dioxide gas is reduced in the chloroplast of the plant cell by gain of electrons to produce carbohydrates. This process transforms the water into oxygen gas and the carbon dioxide gas into glucose molecules (carbohydrates).

Plants need water, so that the guard cells in the plant can fill up and become turgid which would allow the stomata to open and exchange of gases. If there is not much water present in the guard cells, not much gas exchange can occur hence not much of the carbon dioxide can be taken in from the atmosphere.

Answer:

32 chromosomes (16 pair)

Explanation:

Gametes or sex cells of sexually reproducing organisms are produced via a process called MEIOSIS, which is a type of cell division that reduces the chromosomal number of the parent cell by half. Hence, a mice that produces a sperm cell (gametes) via meiosis with 16 chromosomes will have double that amount in somatic cells of that mouse.

That is, the expected number of chromosomes in an adult mouse of this species with 16 chromosome in its sperm cell is 32 since half of this number makes up the chromosomal number in gametes

For example, two animal predators may consume different prey items, so they are less likely to compete with one another, allowing higher total biomass of predators in the system. In the case of plants, all species may utilize the same suite of resources (space, light, water, soil nutrients, etc.)

Explanation:

The presence of large biodiversity can reduce one species dependence on another species as it provides resources such as food which will reduce the chances of a species to become threatened.

Biodiversity can be defined as the variety of all the different kinds of organisms such as the plants, animals, insects and microorganisms which live on the planet.

A large biodiversity is helpful for the species as it increases the stability of the ecosystems. This is possible because it reduces the dependence of one species on another, for the instance for food. For example, if a species has only one food source, it may be easily threatened by the environmental changes. However, if many species similar to it are present in the ecosystem then the chances of the species to become threatened are very low.

Explanation: Plankton tend to hang around surface waters which coral reefs also grow in. And most of that Plankton are plants that need more sunlight. So the sun would be brighter in shallower waters rather than open ocean.

Water can only evaporate when it is heated. When water is under heat, the water molecules vibrate and move around so quickly that the molecules escape into the atmosphere. The molecules become less and less dense as they float into the air.

Incomplete dominance

Explanation:

The inheritance pattern described here is called incomplete dominance (sometimes also referred to as semi-dominance or partial dominance). This occurs when the dominant allele doesn't fully prevent the effects of the recessive allele from being expressed. This results in the trait of the offspring being equivalent to the mix of both alleles. If the rooster's feathers are black and the hen's are white, the chicks' will be grey.
