Answer:

The best definition for biogeochemical cycles is the pathway by which mattress transferred between organism and their environment.

Therefore, the correct answer to the question is option b.

Explanation:

Biogeochemical cycles are the continuous cycle which occur between environment and organisms. In this cycle both the environment and the organism are benefited. The matter which is essential for the organism is taken by them to live their life. And in return they release the materials back into the environment.

The release material is consumed by the the plants, trees, Earth and converted back into the material which is important for the organisms. While converting back the environment is benefited in its various ways.

(b) No. HIV can only be caught by another person of they come in contact with your blood or through sexual intercourse. So it is not possible for others to become infected if they didn't come in contact with the person's blood or have unprotected intercourse. There is no reason for a HIV+ve person to isolate themself from the outside world. They are people just as we are but they only have something that can cause them to be really sick.

Until the , only one-celled organisms lived on land, but during this period, plants became abundant.

Anestetic [448]

The answer is Silurian period (443 million to 416 million years ago). This was the era when life in the seas and oceans began to conquer land. This is associated with a period of warm climate, rising sea and ocean levels hence giving shallow-water grounds where reefs developed. Plants like bryophyte began to develop including the emergence of terrestrial arthropods

Rosa drew a diagram to compare substitution mutations and insertion mutations.

djverab [1.8K]

<h2>Hey There!</h2><h2>_____________________________________</h2><h2>Answer:</h2>

$\huge\boxed{Option A}$

<h2>_____________________________________</h2><h2>Mutations:</h2>

Mutations are the changes produced in the nucleotide sequence of the genome.

There are four main types of mutations

Substitution

Insertion

Deletion

Duplication.

<h2>_____________________________________</h2><h3>DELETION:</h3>

A small segment of chromosome mat be missing. This condition is known as deletion.

For example, Normal chromosome has A B C D E F G. If deletion mutation occurs then mutated chromosome has A D E F G and B C got deleted.

<h2>_____________________________________</h2><h3>DUPLICATION:</h3>

In this condition, a part of chromosome present in exec ess to the normal chromosome.

For example, Normal Chromosome has A B C D E F G. If duplication mutation occurs, then mutated chromosome had A B C B C D E F G and B C is duplicated.

<h2>_____________________________________</h2><h3>SUBSTITUTION MUTATION:</h3>

Substitution is a type of mutation where one base pair is replaced by a different base pair.

For example, in the sequence CAAGT, if C replaces G, it is a substitution mutation.

<h3>INSERTION MUTATION:</h3>

In genetics, an insertion is the addition of one or more nucleotide base pairs into a DNA sequence.

For example, in the sequence CAAGT, if extra base G gets inserted after C, the new sequence would be CGAAGT.

Both substitution and insertion mutations change the position of nucleotide thus, the type of amino acid.

Starches help give you an extra boost of energy during your workout. Starches, as well as sugars, eventually break down into glucose -- your body's main fuel source.

Explanation:

When you eat starchy foods, you'll have a supported energy level over a period of numerous hours. This is separate from sugars, which are simple polysaccharides that give you a quick surge of energy but do blank to keep your energy levels running.

Which statements could be categorized in the "Asexual" section of the Venn diagram? Check all that apply

EastWind [94]

Answer:

The right answer are : mitosis, diploid cells, and identical DNA.

Explanation:

The answers "two cell divisions" and "gametes" refers to a division by meiosis which is a sexual reproduction.

Asexual reproduction or asexual reproduction is a mode of reproduction, which - as opposed to sexual reproduction - corresponds to the capacity of living organisms to multiply alone, without a partner, without involving the fusion of two gametes of opposite sexes. Asexual reproduction is observed in multicellular (animal and plant) and unicellular organisms. In botany, the term often used for the asexual multiplication of plants is vegetative multiplication. In all cases of asexual reproduction, the result is identical to the mother.
