Answers

Answer of the following questions is given below.

Radiant energy is called EMR or electromagnetic energy. This is energy that is transmitted without the movement of mass. This energy is found in waves and is also called light energy. The light is made by the individual particles called protons. Hence the option B is correct. Aerobic respiration is the form of respiration that requires O² in order to generate energy. The full oxidation of nutrients. It produces large amounts of energy. Hence the option D is correct. The anaerobic oxidation glucose is broken down without the presence of oxygen. Instead of carbon dioxide water, lactic acid is made that leads to muscular cramps. Hence the option D is correct. A fungus is an example of a decomposer as the fungus derives nutrients b decomposing the matter. Hence the option C is correct. Producers play an important part in the recycling of matter as they convert the light energy into organic molecules. Hence the option A is correct.

How does pressure change as you move from earths surface to inner core?

Answers

Answer:

The outer core lies under the mantle, and is 1,400 miles thick. Temperatures within the outer core range from 7,200 to 9,000 F. Pressure also increases in the outer core due in part to the weight of the crust and mantle above

Explanation:

Answer:

The inner core at the center of the Earth consists mostly of iron. This layer is less than 800 miles thick. Even though the inner-core temperature is now thought to be hotter than the Sun's surface, the tremendous pressure this deep inside the Earth overrides the effects of temperature and prevents the iron from being liquefied. Instead, the iron at the core is a solid and has a spherical shape. also the other person looked this up on the internet

In the sample of water, there are 100 atoms of oxygen and 200 atoms of hydrogen. How will the mass of oxygen compare to the mass of hydrogen?

Answers

Answer:

The ratio of the mass of an oxygen atom to the mass of a hydrogen atom is therefore approximately 16:1. If we have 2 atoms of each element, the ratio of their masses is approximately 32:2, which reduces to 16:1—the same ratio.

The mass of oxygen compared to the mass of hydrogen is approximately 16:1.

What is a chemical reaction?

There are several types of chemical reactions depending on the reaction mechanisms: combination, single-displacement, double-displacement, combustion, decomposition, combustion and redox reactions.

Thus, 16:1 is the answer.

A nonnative species of fish is introduced into a lake. Which would most likely prevent this fish from becoming a invasive species?

Answers

Answer:

B

Explanation:

A- The lake ecosystem has no other larger fish

B- The fish shares a niche with another species

C- There are no organisms that would eat this fish

D- The fish can thrive in the temperature of the week

The correct answer would be option B.

One of the factors that promote invasiveness in exotic species is if such species lack natural predators or competitors. In other words, the invasiveness of a nonnative species can be promoted when they occupy a previously unoccupied niche, resulting in a lack of competition. The presence of a competitor will either results in a competitive exclusion that might not favor the newly introduced species or resource partitioning that sort of limits their growth.

Hence, in the case of the nonnative fish introduced into a lake, sharing a niche with another species can prevent it from becoming an invasive species.

The second option: meiosis and fertilization

process A is meiosis, you can see that the gamete(haploid cell) results from the diploid cell. The gamete has n chromosomes(39), whereas the diploid cell has 2n(78)

process B is fertilization the two gametes(haploid) fuse together to form the zygote(diploid)

Explanation:

Process A allows the chromosome number in the dog cells to be reduced by half. This is only possible due to meiosis as it undergoes 2 phases of meiosis/cell division which is meiosis I and II. (From 2n to 4n to 2n to n)

(After mitosis, the chromosome number will remain constant even though DNA replication occured in S phase, as there is only 1 phase of mitosis/cell division, so from 2n to 4n back to 2n)

Process B allows the dog gamete cells to undergo fertilization and produce a zygote, therefore the chromosome number returns back to 2n.

(Pollination only occurs in plants, not in animals such as dogs and humans)

The correct answer is Meiosis and Fertilization.

When skin cells are damaged by ultraviolet radiation from the sun, they are replaced by new ones. Explain how this fact provides evidence that supports one or more parts of cell theory?

Answers

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.
