what are the hetrotypes

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.

Some advantages of the sexual reproduction include genetic variation. Genetic variation results into changes in the genetic material (DNA). Thus, the correct option is A.

Genetic variation is the difference in the DNA (deoxyribonucleic acid) among individuals or the difference between different populations. The multiple sources of genetic variation include mutations and genetic recombination. Mutation is the changes in the genetic material of an organism which are the ultimate sources of genetic variation, however other mechanisms, such as genetic drift, contribute to it, as well.

Genetic diversity is important because it gives the species a better chance of survival through variations. However, the genetic diversity can be lost from the species when the populations get smaller and isolated from each other, which decreases a species' ability to adapt and survive better in the condition.

Therefore, the correct option is A.

Answer:

Eblow is a terrible thing.

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: 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.
