Answer:

d. response to stimuli

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.

To prevent a fire hazard, ethylene oxide should only be used in an area without sparks or flames. Thus, the correct option for this question is D.

Ethylene oxide may be defined as a type of highly flammable gas that is significantly utilized in order to sterilize medical equipment. It is a colorless gas with a sweet odor.

It is used primarily to produce other chemicals, including antifreeze. In smaller amounts, ethylene oxide is used as a pesticide and a sterilizing agent.

As this ethylene oxide is a highly flammable gas one must be required to keep this in a place or an area that is free from sparks or any other kinds of flames.

Therefore, to prevent a fire hazard, ethylene oxide should only be used in an area without sparks or flames. Thus, the correct option for this question is D.

On February 21, a student observes that the Moon cannot be seen in the clear night sky. The date when the student is not able to see the Moon again is on March 21. The correct option is D.

The moon is the only natural satellite of the earth. It is white and gray and visible from the earth on nights only. It is the fifth-largest satellite in the solar system.

The moon has different phases seen from the earth because the moon revolves around the sun. The four phases have been named full moon, no moon, C moon, and half moon.

In 28 days, the moon is not visible for one day, then the other day it is visible and C-shaped. The student was seen on February 21.

21 + 27 day means 21 march.

Thus, the correct option is D. March 21.

The statement about the relationship between the ocean and atmosphere which is most accurate is that the ocean can hold heat more efficiently than the air and is denoted as option C.

This is referred to as the layer of gases which envelop the planet and the gases which are present include oxygen, nitrogen etc. The atmosphere ensures that there are gases available for different life forms in the planet as they are required for various types of metabolism and activities.

Ocean on the other hand is referred to as an area which has water present and we know that it has a much higher heat capacity than air which is why it is able to hold heat more efficiently even when it undergoes a slight change in temperature as a result of this property.

This is therefore the reason why option C was chosen as the most appropriate choice.

Explanation:

Sperm fertilizes the egg, the egg turns into a zygote, the zygote then goes through the process of cell division and turns into an embryo.  

• Post ejaculation, the sperm cells meet the egg, and fusion between both the cells takes place.  

• The fusion results in the formation of a single cell, which comprises the genetic material from both the egg cell and the sperm cell, this is called a zygote.  

• The zygote further divides into sixteen cells stage called the morula.  

• Post three days after the formation of morula, formation of the embryo takes place. The embryo attaches to the wall of the mother's uterus.  

Thus, egg and sperm fuse and give rise to the zygote, this zygote further undergoes several divisions and eventually results in the formation of an embryo.

because from muscle cell ,muscle tissue arise and then after development  of muscle tissues organs are formed.

The parts from least complex to most complex is muscle cell, muscle tissue, stomach. So, the correct option is (B).

The human digestive system consists of the gastrointestinal tract with the accessory organs of digestion which involve breaking down food into smaller and smaller components until they can be absorbed and assimilated into the body.

The GI tract consists of series of hollow organs which is joined in a long, twisting tube from the mouth to the anus. The processes of digestion consists of six processes:-

1. Ingestion

2. Propulsion

3. Mechanical or physical digestion

4. Chemical digestion

5. Absorption

6. Defecation.

The complexity of the digestive system involves muscle cell, muscle tissue, stomach and organ system from least complex to most complex.

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.

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.
