<span>Wide variety of fish species.  It always includes this intertidal zone and is sometimes used to mean the same as the intertidal zone. Though, the meaning of "littoral zone" can be overall well beyond the intertidal zone. The littoral zone is the same as a sea, lake or river that is close to the shore. In coastal environments the littoral zone extends from the high water mark, which is very rare inundated, to shoreline areas that are permanently submerged.</span>

Which of the following statements about the import of protein to the nucleus is correct? Choose all that apply.
dem82 [27]

The correct statements are:

•An NLS can be a monopartite or bipartite signal which includes a significant number of basic amino acids.

• The recycling of importins back to their original conformation requires GTP hydrolysis in the cytoplasm.

The other answers are incorrect because GTP is not required for an importin to bind to an NLS but for the release of importin and an NES or nuclear export signal  is the sequence  in a protein for export from the cell nucleus to the cytoplasm, not to the nucleolus.

Ronch [10]

Answer:

Zika virus and West Nile virus are the two pathogens which causes more diseases due to increase the population of mosquito.

Explanation:

Zika virus belongs to the family of Flaviviridae. Aedes mosquitoes which are active at day time are the carrier of this virus. West Nile virus is also spread through the bite of mosquito. The infected mosquito is the main cause of spreading of this disease. This virus is spreading too fast in the United States of America in the summer season where the population of mosquitoes increases.

In humans, the hormone testosterone enters cells and binds to specific proteins, which in turn bind to specific sites on the cel
Crank

Answer:

They act to regulate the expression of specific genes (androgen-responsive)

Explanation:

Testosterone is a reproductive hormone in male humans. Testosterone as well as its closely related hormones e.g dihydrotestosterone, all belong to a class of hormones called "Androgens".

Androgens operate by entering into a cell and binds with specific androgen-receptor proteins (AR proteins). This contact activates the AR proteins, forming an androgen-receptor complex.

This complex then translocates into the nucleus of specific cells to bind to the DNA. Once it binds, it either inhibits or promotes the expression of specific genes (androgen-responsive). Hence, AR proteins are transcription factors because they play a significant role in regulating transcription of specific genes i.e. turning 'on' or 'off' of specific genes.

This process helps to direct the development of male sexual characteristics.

What type of chromosomal abnormality can lead to multiple copies of a gene, some of which can incur mutations that can lead to t
koban [17]

A trisomy is a chromosomal condition characterized by an additional chromosome. A person with a trisomy has 47 chromosomes instead of 46.

Trisomy means the presence of an extra chromosome in some or all of the body's cells. This results in a total of three copies of that chromosome instead of the normal two copies. For example, Down syndrome (trisomy 21) is caused by having three copies of chromosome 21 instead of the usual two copies.

This genetic condition is the result of a genetic mutation where your cells don't divide as they should. You can't prevent this abnormality from happening during cell division.
