URGENT PLEASE HURRY ​

Answer: The process is called EUTROPHICATION. The correct option is C.

Explanation:

Eutrophication is a type of environmental pollution where by there is an increase in nutrient salts of a water body which can lead to structural changes in the affected aquatic ecosystem. These changes includes:

--> Increase in production of algae: this effect causes algae blooms which makes the water murky, greenish and unpleasant for certain activities such as swimming.

--> Decrease in aquatic life: the presence of excessive growth of algae which are often degraded by microorganisms. When the rate of degradation of the algae by microorganisms is greater than that of oxygen regeneration a hypoxic state occurs which is harmful to aquatic life example fishes.

Answer:

Mutations are errors in codons caused by changes in nucleotide bases. Some mutations may not have much effect. For example, if the codon GAA becomes the codon GAG, because the genetic code is degenerate, the codon will still code for the amino acid glutamate. Such ineffectual mutations are called silent mutations. Some mutations, however, can have a huge affect on coding for amino acids, which can in turn affect what proteins are produced, which can have a profound effect on cellular and organismal function.

Answer:

Cancer cells differ from normal cells in many ways that allow them to grow out of control and become invasive. One important difference is that cancer cells are less specialized than normal cells. That is, whereas normal cells mature into very distinct cell types with specific functions, cancer cells do not.

Explanation:

Answer:

The correct answer is option D.  Light and some other factors are necessary for chlorophyll production

Explanation:

By this experiment, it is clear that light is the major factor that helps in the production of chlorophyll in seedlings or plants. In this study, placing the seeds in the light turns 75 seedlings green which is possible by the production of the green pigment, chlorophyll only. So, it is proved that light is a key factor in the production of chlorophyll.

Besides light, there must be some other factors (mineral nutrition and chemical metabolites) that also play role in the production of chlorophyll or increase or decrease of the chlorophyll production as few seedlings did not turn green in the study.

Explanation:

Answer:

I think its, option b) Viruses are not living organisms, but bacteria are living.

Explanation:

The other options don't fit "summarize the differences b/w bacteria and virus", or simply don't make sense...  

Bacteria can replicate as well, not only virus, so that cannot be a difference

The virus is often the one being more dangerous, there is something called "good bacteria"

A virus isn't  living, (for the sake of this answer), and we all know for sure that bacteria is living

So, that's how option b is correct

Answer:

Infiltrate rate decreases and also water quality.

Explanation:

There is adverse effect of erecting buildings and concrete pavement on the recharge of aquifers and the quality of the water because the water is unable to infiltrate inside the soil due to concrete floor and the recharging of aquifers is not possible. These buildings and concrete pavements also reduces the quality of water due to degradation of sediments present in the building with the passage of time.

Answer:

There will be 7 neutrons in a carbon isotope with an atomic mass of 13.

Explanation:

The number of protons in the carbon isotope will be the same as the atomic number, 6, so if we need an atomic mass of 13 there will be 7 neutrons, as 6+7=13.

If the atomic number of an element is 6 and its mass number is 13, there will be 7 neutrons. Therefore, the correct statement is option C.

Atomic number is the number of protons found in the nucleus of an atom of a specific chemical element. The atomic number is also equal to the number of electrons orbiting around the nucleus in a neutral atom.

Mass number is the total number of protons and neutrons found in the nucleus of an atom and is represented by the symbol A. The mass number is used to determine the atomic mass of the atom.

The atomic number of an element is the number of protons present in its nucleus, which is 6. The mass number of an element is the total number of protons and neutrons in its nucleus, which is 13. So, the number of neutrons in the nucleus can be calculated by subtraction of the atomic number from the mass number.

The formula is number of neutrons = Mass number - Atomic number.

Therefore, there are 7 neutrons in the nucleus of the given element.

The fertilizers show a significant impact on the nitrogen cycle as the fertilizers kill off the important nitrogen fixing bacteria which are present in the soil. Thus, the correct option is C.

Nitrogen Cycle is a biogeochemical process through which the nitrogen present in the environment is converted into many different forms, consecutively passing from the atmosphere to the soil to the living organisms and back into the atmosphere after decomposition. It involves several processes including the nitrogen fixation, nitrification, denitrification, decay and putrefaction of the nitrogen compounds.

Intensive fertilization of the agricultural soils of normal soil can increase the rates at which nitrogen in the form of ammonia is volatilized in the environment and lost to the air. It can also speed the microbial breakdown of ammonium and nitrates in the soil which results into enhancing the release of nitrous oxide. In addition to this, excessive use of fertilizers also kills the nitrogen fixing bacteria present in the soil.

Therefore, the correct option is C.
