What responses it takes to open or close ion channels

Biology

Depolarization and Hyperpolarization occurs when ion channels open and close.

Explanation:

In some specific part of the membrane of neuron, the potential of the membrane becomes less positive it is that results in Hyperpolarization. Depolarization is in contrast with this, since the potential of the membrane will become less negative in this type. these two types occurs during the opening and closing of ion channels that are present in the membrane. This will result making the ions either entering the cell or exiting the cell.

hyperpolarization occurs when the channels opens and resulting in letting the ions that are positive to exit out of the cell. When the channel opening results in letting the positively charged ions to get into the cell, then depolarization occurs. The channel opening and closing highly depends on the binding nature of the molecules that are signalling.

Recall that two hydrogen bonds bind A and T, but three hydrogen bonds bind G and C. Because the stability of DNA is affected by
IrinaK [193]

Answer:

A molecule with 32 percent or more amount of Cytosine.

Explanation:

DNA is the genetic material of all the living organism but in few viruses, RNA can also acts as the genetic material. DNA contain nitrogenous bases ( adenine, guanine, thymine and cytosine), deoxyribose pentose sugar and the phosphate bond.

The triple bond is more stable than the double bond. Since, cytosine and guanine shows triple hydrogen bonding and shows more stability. The DNA molecule that contains more residues of guanine and cytosine is stable than the molecule containing adenine and thymine residues.

Thus, the answer is molecule with 32 percent or more amount of Cytosine.

Prescribe how mountains change in abiotic conditions with an increase in elevations
olga55 [171]
The first famous natural scientist to determine how plants change with altitude on tall mountains was Alexander Von Humboldt and Aime Bonpland when climbing some very high volcanoes in South America like Chimborazo at well ove 20,000 feet high and they observed that different plants grow at different altitudes as altitude increases so that as the mountain was ascended the new environments of temperature, moisture,etc would become abiotic for the lower plants but acceptable for the higher elevation plants. In these cases in South America, the lower elevations had very warm temperatures and high humidity so would grow tropical plants with probably large leaves like palm trees etc. On the other hand at high elevations the temperature would be significantly decreased and probably humidity decreased too so only rugged plants like say lichens could grow. At intermediate elevations, most likely say pine trees could grow as I know they do at moderate elevations in Honduras for example.

What happens during cellular respiration
Vera_Pavlovna [14]

Answer:

in cellular respiration food is oxidized to CO2 while O2 is reduced into H2O Cellular respiration takes in food and uses it to create ATP, a chemical which the cell uses for energy. Usually, this process uses oxygen, and is called aerobic respiration.Aerobic respiration, the process that does use oxygen, produces much more energy and doesn’t produce lactic acid. It also produces carbon dioxide as a waste product, which then enters the circulatory system
