What is the main difference between the intertidal zone and the neritic zone?

the amount of exposure to sunlight
the amount of salt in the water
the amount of time covered by water
the presence of plants and animals

Answers

Answer:

intertidal zone is the area of shore between the high tide and low tide lines whereas neritic zone is the area of the ocean from the low tide line out to the continental shelf.

The main difference between the intertidal zone and the neritic zone is the amount of time covered by water.

What is intertidal zone and the neritic zone?

The intertidal zone is the area of the shoreline that is regularly exposed to air at low tide and submerged at high tide. This area is characterized by its exposure to fluctuations in water level, temperature, and salinity, and is home to a diverse range of organisms that have adapted to these conditions.

The neritic zone, on the other hand, is the shallow ocean water over the continental shelf, extending from the low tide mark to a depth of about 200 meters. Unlike the intertidal zone, the neritic zone is always covered by water and is characterized by relatively stable physical conditions, including a relatively constant temperature and salinity.

While the amount of exposure to sunlight can vary in both the intertidal and neritic zones, the main difference between these two habitats is the amount of time covered by water and the resulting stability of environmental conditions.

Answers

Answer:

419 Falcons

Explanation:

P= Poe^rt

P= population at time t = ?

Po = initial population = 300

The figure above depicts the DNA-protein complex that is assembled at the transcriptional start site of gene X when the expression of gene X is activated in liver cells. Previous studies have shown th gene X is never expressed in nerve cells. Based on the diagram, which of the following most likely contributes to the specific expression pattern of gene X?
A.Expression of gene X produces large amounts of tRNA but undetectable amounts of mRNA.
B The general transcription factors inhibit the activation of gene X in liver cells by blocking the activator from binding to RNA polymerase II.
С The activator is a sequence-specific DNA-binding protein that is present in some tissues but not in other tissues.
D The enhancer is a unique DNA segment that is added to the nuclear DNA of some cells of an organism during the process of mitotic cell division but not other cells.​

What is gene expression?

Gene expression is the process through which a gene's information is used to create a functioning gene product, allowing it to produce end products like proteins or non-coding RNA and ultimately have an impact on phenotypes.

Because a particular protein can only be made when its gene is turned on, gene expression is significant.

However, there are several steps involved in translating a gene into a protein, and one of these steps—the creation of proteins—is crucial in the gene expression pathway that can be changed in cancer.

According to the diagram, the activator is a DNA-binding protein that only binds to certain sequences in select tissues.

Thus, the correct option is C.

Answers

Answer:

Explanation:

Due to drought condition, the level of ground water decreases because of pumping of water for the irrigation purpose. Huge amount of water is required to irrigate a large area of California and in the drought conditions ground water is the only solution for this problem. The diversion system will be useful California by diverging river into these drought affected areas in order to fulfill the need of water for growing crops so we can conclude that this diversion system helps to fulfill the necessity of water during drought situation.
