Answer:

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.

Answer:

Hypertonic: cell with shrivel

Hypotonic: cell will lyse (expand)

Isotonic: cell with not change

Explanation:

Hypertonic has a higher concentration outside the cell so there will be a net flow of water out of the cell

Hypotonic has a lower concentration outside the cell so there will be a net flow of water into the cell

Isotonic is when the concentration is the same so there will be no net flow of water

An hypertonic solution has a higher concentration than the inside of the cell's cytoplasm, a hypotonic solution has a lower concentration that the cell's cytoplasm an isotonic solution has the same concentration as the cell's cytoplasm. When placed in a hypertonic solution the cell will lose water through osmosis and will shrink. When placed in a hypotonic solution the cell will absorb water through osmosis and it will increase in size untill it bursts. This proces is called cytosis. When placed in an isotonic solution the cell will keep it's initial size.

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.

A structure within a cell that performs a specific function is an organelle.

Explanation:

An organelle is a structure inside the cell that preforms functions that are necessary for the cell.

Examples of organelles are the ER, the Golgi Apparatus, and the Mitochondria.

Hope this helps.

A structure within a cell that performs a specific function is an organelle. An organelle is a subcomponent of a cell.

Cell organelles are the ultrastructure's present in the cell and they show division of labor.

These organelles perform specific function for the cell and thus constitute the framework of all living organisms.

The basic structure of cell contains a plasma membrane, nucleus and cytoplasm. However, ultra-microscopic structures are embedded in the cell cytoplasm and they are designated as organelles in a cell.

Endoplasmic reticulum, Golgi apparatus, mitochondria, ribosomes, microtubules, lysosomes etc. are the specialized organelles present in cell.

Each of these organelles perform specific function. For instance, mitochondria help in energy production, Golgi helps in protein modification and packaging.

Cell organelles are thus important structural and functional elements of a cell.

Science is a branch of study that deals with answering questions and solving problems. However, there are different scientific principles used to tackle the problems in science. One of them is a THEORY, which is a detailed and well explained fact about a natural phenomena. A theory is said to be an hypothesis that has been subjected to series of experimental testing and found to be accurate or consistent.

In this question, a series of experiments was designed and conducted by several science teachers around the world. The results were found to be consistent that students who stayed up all night playing before their finals did -40% worse than students who didn't. This comprehensive and well explained observation using repeated experiments depicts a THEORY.

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.

B. in order to maintain healthy skin, your dead cells must be replenished

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.

1. Ingestion

2. Propulsion

3. Mechanical or physical digestion

4. Chemical digestion

5. Absorption
