What initiates an action potential on a muscle cell?

Plants contain the carbohydrates starch and cellulose. In the spring when stem growth is at its fastest rate, cellulose producti

Alexandra [31]

Answer:

B. Two functions of carbohydrates are structural support and transferring genetic information

Explanation:

Carbohydrates are synthesized in green plants, thanks to photosynthesis, in which carbon dioxide (CO2) and water are converted into glycides, with energy provided by light. The energy stored in the glucose molecule during photosynthesis is released in the degradation (catabolism) of glucose, producing water and CO2.

From the point of view of metabolism, the main function of carbohydrates in plant organisms is to provide energy and provide structural support. This can be seen in the question above, because we can see that in spring, when stem growth is at its fastest pace, cellulose production rates increase in some plants, while in months with less sunlight, the level of starch decreases in some plants.

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.

Is a waste product that uses the most energy to produce

viktelen [127]

A waste product is a product that is made but isn’t necessarily needed eg. A lightbulb will make light energy but it also makes a waste product heat.

(c) find the longest interval during which no tree-cutting samples occurred. what is the first year that no tree-cutting samples

MaRussiya [10]

Answer:

Longest interval during which no tree-cutting sample occurred: 9 years (1203 AD - 1212 AD)

First year in that interval: 1203 AD

Explanation:

Lets complete the question first.

Q) A study uses tree rings to determine the year in which a tree was cut. The data is shown in the leaf and stem diagram in the ATTACHMENT.

The three digits number in the left column represents centuries and decades AD. The numbers on the right represents the years.

For example, consider the first input in the diagram

119 | 5 6

which means it represents 2 samples.

1195 AD, 1196 AD.

The longest interval with no tree-cutting samples is found from 1203 AD to 1212 AD.

A client underwent a mastectomy 24 hours ago. which information will the nurse include in the plan of care?

Ainat [17]

I think the nurse should include, the hand and elbow of the affected arm will be elevated above the shoulder. Mastectomy is the medical term for the surgical removal of one or both breasts, partially or completely, normally carried out to treat breast cancer. It is also usually used for women at high risk who have prophylactic mastectomy.
