Answer:

B: Psychology

Answer: C -Leaves contain cells that absorb sunlight and water during photosynthesis.

Explanation:

Leaves contain cells that absorb sunlight and water during photosynthesis. That's why after three hours the amount of water decreases as the number of leaves increases. Option (C) is correct.

Water is taken up by roots from the soil and moved as a liquid by xylem to the leaves. Small holes in the leaves allow CO2 to enter the leaf for photosynthesis and water to escape as a vapor.

The rate of gas exchange is regulated by stomata, which are pores present in the epidermis of leaves, stems, and other organs. A pair of specialized parenchyma cells called guard cells surrounds the pore, controlling the size of the stomatal opening.

They are essential to photosynthesis because they allow carbon dioxide to enter the leaf and oxygen to leave. Additionally, the stomata aid in transpiration, the process of releasing water vapor through a plant's leaves.

Thus, option (C) is correct about leaves.

B)Fusion reactions do not produce harmful radiation and transuranium nuclides.

Explanation:

___________

The benefit of utilizing fusion reactions instead of fission reactions is that the fusion reaction does not produce harmful radiation and transuranium nuclides. Thus, the correct option for this question is B.

Fusion may be defined as a type of process that significantly involves the combination of two or more atoms or molecules in order to form one larger molecule. This type of reaction normally occurred in nature as compared to fission.

The process of fission involves the disintegration of numerous smaller molecules or atoms from a larger one. This creates a lot of long-lived radioactive substances in nature that are harmful to live organisms. These types of reactions are not favored by nature.

Therefore, fusion reactions do not produce harmful radiation and transuranium nuclides are the benefit of utilizing fusion reactions instead of fission reactions. Thus, the correct option for this question is B.

Allele frequency- the percentage with which a specific allele is found in a population. Gene Pool- the sum total of all alleles present in all populations of a particular species. ... evolution involved a change in allele frequency in a population's gene pool over a number of generations.

Explanation:

I hope this helps :)

A gene pool is defined as the number of alleles. and the allele frequency is defined as the  genes that appear in a population. Therefore, option B is correct.

A gene pool is the collection of all the genes (including alleles) found in a population or species that is capable of reproduction. A big gene pool has a wide range of genetic diversity and is more resilient to environmental stresses.

A gene pool is the collection of all the genes, including all the various alleles, in any population that mates with other individuals from the same or different species. The percentage of an allele within a population is known as the allele frequency.

A population's gene pool will include a high number of genes with a wide range of frequencies. Gene frequencies are proportions of various alleles within a population, and in any given generation, these frequencies will rely on those of the previous generation.

50% roan

25% white

Explanation:

When RR (red) is crossed with WW (white), it results in roan color.

       RR (red)   x    WW (white)

              RW (roan)

Two roan individuals are then mated.

          RW    x    RW

       RR    RW    RW    WW

The function of the vacuole is to maintain the turgid pressure that is to maintain the cell turgidity. It stores water along with the dissolved salts in it. The answer is option B.

There are various enzymes that are present in the vacuoles and it is just like the pool of the plant cell which stores the various enzymes along with the water molecules and the dissolved salts.

With its roles that perform or help  in the  plant cell function that are  the central vacuole which stores salts, minerals as well as  nutrients,  along with proteins and  pigments that  helps in the  plant growth and plays important structural  kind of role for plant. The  organelle that is the central vacuole of plant cells that  helps it to just  maintain the volume along with the structure.

Vacuoles store the  materials like water along with  salts and  proteins as well as the carbohydrates.  Most of the plant cells that are  having  a single or the large central vacuole.
