A.P.E.X
The element that is highly reactive nonmetal is Chlorine. The correct option is C.
What are non-metals?
Nonmetals are elements that lack metallic properties. They contain colorless gases and some solid.
Chlorine is a non-metal gas, and it is highly reactive because it is a halogen.
Thus, the correct option is C, chlorine.

How can a person's muscle cells have the same exact DNA sequences as their nerve cells even though they look and perform completely
A. The two different cells become mutated.
B. The genes expressed in each cell are different.
C. They actually have different DNA in the two types of cells.
D. The genome of the different cells changes
Answers
A person's muscle cells have the same exact DNA sequences as their nerve cells even though they look and perform completely differently due to the expression of different genes in each cell. Thus, the correct option for this question is B.
What are Muscle cells?Muscle cells may be defined as those cells that have the capability to shorten or contract in order to produce movement of the body parts. These types of cells typically facilitate the momentum of the whole body.
Each cell of the living organism including humans has the ability to turn on or off the functions of those genes which are required for their function or not. Due to this mechanism, the nerve cell synthesizes different genes with respect to the muscle cells irrespective of the DNA sequence.
Therefore, the genes expressed in each cell are different is a correct option with respect to this question. Thus, the correct option for this question is B.

What do the phase changes (condensation, evaporation, crystallization) in the water cycle have in common?
Answers
Change in thermal energy from the Sun is the common factor during the phase changes ( condensation, evaporation, crystallization) in the water cycle.
What is Water Cycle ?Water cycle is the continuous movement of water between Earth and atmosphere. It is also known as Hydrological cycle. Water Cycle occurs in three phases i.e. Solid , Liquid and Gas. This cycle never stops, it doesn't have a beginning or an end. It's like a big circle.
Liquid water evaporates into water vapour which condense to form cloud and precipitates back to earth in the form of rain or snow. It is a simple circular cycle of evaporation, condensation and precipitation.
Water vapour is the primary form of atmospheric moisture. Its storage is small, water vapour is extremely important in forming the moisture supply for dew, frost, fog,etc.
There are Five parts of the water cycle. They are
1. Evaporation
2. Transpiration
3. Condensation
4. Precipitation
5. Runoff.
Thus, change in thermal energy from the Sun is the common factor during the phase changes ( condensation, evaporation, crystallization) in the water cycle.

If you breathed in a lot of chlorine at the pool, which of your cells would be affected? If an embryo were exposed to chlorine, which of his cells would be affected?
Answers
Answer:
I HATE KEYONNN\
Explanation:
If a lot of chlorine is breathed in, then it would harm the lungs' cells, especially the cells of the airways, the pseudostratified epithelial cells. It harms the different organs of developing embryos as it depends on the mother.
What is breathing?Breathing is the process of taking the oxygen inside the lungs from the atmosphere and releasing the carbon dioxide into the atmosphere. If a large amount of chlorine is taken, it will affect the cells in the airways.
Long-term inhalation of such gases causes lung problems such as acute lung disorder, asthma, pulmonary pneumonia, and so on. If such a condition arises, then it would be very difficult to provide proper oxygen to the body, and many other cellular activities would be affected.
In the case of developing embryos, it depends on the maternal supply. If the maternal blood is toxicated with chlorine, then it will supply the baby, and the developing baby organs will be affected. There are many disorders such as improper development of the brain, lungs, bones, etc. It will affect the embryo's cognitive capacity too.
Hence, a lot of chlorine affects the lungs the most when breathed.
