Lesechka [4]

Answer: Methylene blue can be used to stain DNA of a cell because it (forms ionic bonds with DNA).

Explanation:

To examine the components of a cell usually under a microscope, a stain or dye is being used to provide a clear and defined view of the area under study.

The deoxyribonucleic acid (DNA) of a cell which contains the hereditary information of the cell is located in the nucleus.

Methylene blue is a type of stain used by biologists which helps them view microscopic life in brilliant color. It is a cationic stain (positively charged blue dye); and binds to negatively charged parts of the cells, such as nucleus (DNA) and RNA in the cytoplasm (with lower affinity).

When DNA of a cell comes in contact with methylene blue on a slide, their opposite charges attract, causing methylene blue's "rings" to slide in between the "rungs" of the DNA "ladder." As a result, a rich blue stain that identifies the location of the cell nucleus can be observed. This produces a photosensitive reaction which can then be viewed under the microscope.

Therefore is can be used to stain the DNA of cell because it forms ionic bonds with DNA.

Explain how the cell cycle is regulated.
irina1246 [14]

Solution:

Cell-division control affects many aspects of development. Caenorhabditis elegans cell-cycle genes have been identified over the past decade, including at least two distinct Cyclin-Dependent Kinases (CDKs), their cyclin partners, positive and negative regulators, and downstream targets. The balance between CDK activation and inactivation determines whether cells proceed through G1 into S phase, and from G2 to M, through regulatory mechanisms that are conserved in more complex eukaryotes.  

This is the required process through phosphorylation, Cdks signal the cell that it is ready to pass into the next stage of the cell cycle. As their name suggests, Cyclin-Dependent Protein Kinases are dependent on cyclins, another class of regulatory proteins. Cyclins bind to Cdks, activating the Cdks to phosphorylate other molecules.

If a person moved from boston to miami, how would the normal pattern of adh secretion be altered? Could a person prepare to move
Softa [21]

Boston is colder than Miami.

Therefore, more water is lost in the form of sweat in summer than in winter. In the summer, your body becomes dehydrated, releasing more ADH in your body.

ADH Syndrome of antidiuretic hormone or vasopressin is synthesized by the hypothalamus and released from the posterior pituitary gland to maintain blood osmolality. It increases the reabsorption of water from the kidney nephrons.

Therefore, in a cold environment like Boston, ADH will be low and will increase significantly in Miami.

Several chemicals change ADH levels.

Drugs that raise ADH levels include vasotrict and vasopressin.

Drugs that lower ADH includes alcohol.

Therefore, some chemicals can affect ADH levels in the blood.
