Answer:
See the answer below
Explanation:
When skin cells are damaged by ultraviolet radiation from the sun, the cells present in the tissue of the skin are triggered to start dividing by mitosis in order to produce new cells that replace the damaged cells. Thus, new cells are produced from the old cell.
This phenomenon agrees with the part of the cell theory that says that cells can only arise from preexisting cells. More specifically, cells are only able to arise from preexisting cells through the process of cell division.
The damaged skin cells are replaced by the new cells, which are formed of the cells that preexists, that is, present already, this supports one of the cell theory that all cells originate from the preexisting cells.
• The three prime points of the cell theory are that all the living things are formed of cells. The cells are the fundamental units of life, and all the cells comes from the preexisting cells by the process of cell division.
• The cells are always formed from the cells already present.
• In case, if the skin cells gets damaged by UV rays from the Sun, they get replaced by the help of cells, which are already present underneath the dead cells.
• These new cells do not come from thin air, the cells underneath get triggered and by the process of mitosis give rise to novel cells.
Thus, the replacement of the damaged skin cells by the new cells proves theory that all the cells comes from the preexisting cells by the process of cell division.

If a person in the northern hemisphere observes a full moon, what moon phase would a person in the southern hemisphere observe on the same night? Be detailed in your explanation.
(SCIENCE)
Answer:
nooo
Explanation:
because the earth rotates changing the hemispheres
An increasing waxing moon's phase is seen from the Northern Hemisphere as it moves from right to left. Meanwhile, a waxing moon increases its phase from left to right as seen from the Southern Hemisphere.
What is Hemisphere?Hemisphere is defined as the Earth is evenly divided into two half by any circle that is drawn around it. The atmosphere is one of the fundamental elements of Earth's interrelated physical systems. The layers of gases that envelop a planet or other celestial body are its atmosphere. About 78% of the gases in the Earth's atmosphere are nitrogen, 21% are oxygen, and 1% are other gases.
In comparison to the northern hemisphere, the Moon does appear to be "upside down" in the southern hemisphere. It's only an issue of orientation here. Imagine that the equator and the Moon's orbital plane are the same.
Thus, an increasing waxing moon's phase is seen from the Northern Hemisphere as it moves from right to left. Meanwhile, a waxing moon increases its phase from left to right as seen from the Southern Hemisphere.

sweat acts as a cooling agent on the body because of water high heat of vaporization or high specific heat capacity?
Explanation:
Large amounts of heat are needed to evaporate water, because H-bonds need to be broken. Sweating is an example of using water as d coolant. As the sweat evaporates it pulls heat away from the body. Application 'Water's thermal properties, its high specific heat, means that it can cool us.

Suppose you created a set of Instruments using water and drinking glasses. You need a note with a very low pitch to complete a certain song-what should you do? Pour out some of the water in the glass with the most water. Add more water to the glass with the most water. Pour out some of the water in the glass with the least water. Add more water to the glass with the least water.
Answer:
Add more water to the glass with the most water.
Explanation:
The glasses with more water have lower pitches and the glasses with less water have higher pitches. To create a lower pitch you need to add more water to the glass with the most water. If there is no room to add water, you need a larger glass!

1. What is the scientific method? Is there just one universal scientific method? Why or why not?
Answer:
There is no such unique standard method—scientific progress requires many methods—but students in introductory science courses are taught that `The Scientific Method' is a straightforward procedure, involving testing hypotheses derived from theories in order to test those theories.
Explanation:
There is not a specific method. There are either 20 or 30 different ways you can do it.. I believe.
Make an observation, ask a question, form a hypothesis, make a prediction based on the hypothesis, test the prediction, make a new hypothesis based on the results.

The following occurs in meiosis but not in mitosis: pairs of homologous chromosomes are separated. This is present in the third option, and in the process, the homologous pair of chromosomes is separated in meiosis I.
What does the meiosis process carry out in the cell?Meiosis and mitosis share many similarities, such as replicated DNA separation, spindle fiber formation, and nuclear membrane fusion, but the difference between the two is that meiosis has homologous chromosome separation, whereas mitosis does not. The meiosis in this process makes four haploid cells, and the mitosis makes two diploid cells from a single daughter cell.
Hence, the following occurs in meiosis but not in mitosis: pairs of homologous chromosomes are separated. This is present in the third option, and in the process, the homologous pair of chromosomes is separated in meiosis I.

acid precipitation results when___and____ compounds react with water in the atomsphere
Answer:
Sulfur; nitrogen.
Explanation:
Acid precipitation results when sulfur and nitrogen compounds react with water in the atmosphere.
This acid precipitation is also known as acid rain and it is typically caused by the chemical reaction between sulfur oxide and nitrogen oxide which are released into the air as a result of burning fossil fuels, with water and other chemical elements present in the atmosphere.
Generally, acid precipitation (acid rain) usually have a pH of about 5.1 or below and as such, it is very acidic nature i.e possessing a large amount of hydrogen ions.
Hence, acid precipitation (acid rain) when washed to the earth has negative or harmful effects on various living and non-living organisms such as animals, plants, cars, buildings etc.
