<span>The main reasons why cell division is important in organisms are reproduction, repair and growth. Cell division is necessary in order for life to continue.
</span><span>
The length of the cell cycle is important because it determines how quickly an organism can multiply. For single-celled organisms, this rate determines how quickly the organism can reproduce new, independent organisms. </span><span>Most of the differences in cell cycle duration between species and cells are found in the duration of specific cell cycle phases. DNA replication, for example, generally proceeds faster the simpler the organisms. One reason for this trend is simply that prokaryotic have smaller genomes and not as much DNA to be replicated.</span>

1. An underdeveloped DNA molecule would result in mutations. On the genetic level, this could mean entire traits are deleted or that an early stop occurs in transcription, which could cut off parts of instructions.

2. Genetic code is the nucleotide sequence of a gene while the gene expression is how these sequences are used to make functioning amino acids and proteins to create DNA.

3. In each cell itself there are roughly 42 million proteins.

Capsular hydrostatic pressure is the chief force pushing water and solutes out of the blood and across the filtration membrane.
frozen [14]

Answer:

False

Explanation:

Capsular hydrostatic pressure is not the main force that pushes water and solutes out of the blood and through the filtration membrane.  On the contrary, this pressure acts against the filtration membrane, making it difficult for water and solutes to escape from the blood.

Increasing this pressure decreases the infiltration rate and causes obstruction of the urinary tract that tends to accumulate urine, causing a lot of pain to the patient with  Renal Failure.

What is the most likely explanation for the results in the graph?
Delicious77 [7]

Answer:

B. The apple orchard releases toxic chemicals into the water of the  bay.

Explanation:

Option B is the correct answer. It is the most likely explanation for the results in the graph.

From the graph, we can see that the population of the fishes sharply dropped. Since the fertilizer is applied to the apple orchard and the orchard was planted beside the bay, during the rain it is possible that the water has washed some of the fertilizers into the bay. The chemicals used in making fertilizer are harmful and toxic.

This reveals that the toxic chemicals released from the apple orchard are responsible for the decline in the population of the fish.

A student added a solution to the plant cell shown in image 1 which resulted in the plant cell undergoing changes, as shown in i
Ymorist [56]

Answer:

Plasmolysis

Explanation:

In the image 1 the cell is having sufficient quantity of water leading to a turgid cell.

The image 1 plant cell is in a dilute solution in which water enters into cell from external medium.

The image 2 plant cell is exposed to a solution which is high concentrated solution.

Due to this high concentrated  solution the water present in  the cell is send out by exosmosis.

Due to loss of water from plant cells the protoplasm in plant cell shrinks in which cell membrane gets separated from  cell wall.

This shrinkage of protoplasm by loss of water is called plasmolysis.
