The sodium channel possesses an inactivation gate that temporarily closes after the channel is active.
In neurons, sodium channels are responsible for the ascending phase of the action potential (depolarization).
Characteristically, this channel has two transmembrane voltage-dependent gates.When the membrane is depolarized to the threshold, both gates are activated, but since one of them opens rapidly while the other closes slowly, the channel remains open for less than 2-5 milliseconds.Therefore, we can conclude that the sodium channel is responsible for the depolarization and possesses two gates which one temporarily closes after the channel is active.

Severe combined immune deficiency (SCID) describes a condition in which neither _____ nor _____ are functional. Question 1 options: innate; acquired immune responses MHC class I; MHC class II molecules T-cell-dependent antibody responses; cell-mediated immune responses classical; alternative pathways of complement
Answer: Cell dependent antibody responses; cell-mediated immune responses
Explanation: We know that this is an immune deficiency, so it has to do with something in the immune system and its immune cells. The cells of the immune system help to make sure things travel safely as well as the antibodies they produce.
What arctic animals will climate change affect? How will it affect these animals? (Site 1).
Answer: Narwhals, polar bears, and walruses will be affected the most.
Explanation:
Polar bears: The Arctic is warming about twice as fast as the global average, causing the ice that polar bears depend on to melt away. Loss of sea ice also threatens the bear's main prey, seals, which need the ice to raise their young.
Narwhals: The Narwhal's Arctic habitat is highly sensitive to climatic changes that result in increased atmospheric and ocean water temperatures. The Narwhal's annual migration from the north in summer to more southerly overwintering habitats exposes them to sea ice which is constantly expanding and receding. Because of the sea ice rapidly decreasing, narwhals could be exposed to new threats and noises.
Walruses: Habitat loss will be exacerbated for walruses by additional climate-change related factors such as ocean acidification, increased shipping and increasing development in the North, including oil and gas extraction, as well as increased disease and contaminant risks. biggest threat facing walruses is the loss of stable sea ice due to climate change. As a result of less sea ice, walrus are changing their behavior. Walruses feed on the ocean floor in the relatively shallow waters of the continental shelf, where the sea ice itself sustains a rich food web.

What type of shock occurs when bacterial toxins trigger vasodilation and increase capillary permeability
Septic shock occurs when bacterial toxins trigger vasodilation and increase capillary permeability.
Vasodilation occurs during inflammatory processes thereby leading to an increase in blood flow. Septic shock cause the release of numerous vasodilatory chemicals thereby leading to lethal hypotension.
Septic shock is caused by changes in hemodynamic profile as a result of endothelial dysfunction with increased capillary permeability thereby leading to hypotension.

when the lac repressor protein binds to lactose, why does it fall off its binding site at the operator?
Answer:
English is not my native language so sry if there's any grammaticaly mistake
Explanation:
cuz it changes its shape and forme u got that?!
Lactose falls off its binding site at the operator because the allolactose binds to the repressor causing it to fall off the operator side.
What do you mean by Lac repressor?Lac repressor prevents the transcription of genes involved in lactose utilization in E. coli, such as lac genes.
When lactose becomes available a small amount of it is taken up by lactose permease and converted to allolactose by the enzyme beta-galactosidase.
Therefore, Lactose falls off its binding site at the operator because the allolactose binds to the repressor causing it to fall off the operator side.

During photosynthesis, plants produce _____________ and oxygen from the _____________________________ of solar energy, water, and carbon dioxide
Answer:
During photosynthesis, plants produce glucose from simple inorganic molecules - carbon dioxide and water - using light.
Explanation:
Most life on Earth depends on photosynthesis.The process is carried out by plants, algae, and some types of bacteria, which capture energy from sunlight to produce oxygen (O2) and chemical energy stored in glucose (a sugar). Herbivores then obtain this energy by eating plants, and carnivores obtain it by eating herbivores.
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.

Which of the following is a binocular cue for depth perception?.
A binocular cue used to assess depth between two nearby objects is called retinal disparity.
What is the binocular cue for depth perception?The pictures that both eyes focus on to create stereopsis, or the feeling of depth, is known as binocular depth cues. Using binoculars, one may see the world in three dimensions.
Binocular depth signals can be classified as either retinal disparity or convergence. Convergence centers on a single object while using both eyes.
A binocular cue used to assess depth between two nearby objects is called retinal disparity. It accomplishes this by contrasting the various pictures from the two retinas. Because the distance between each eye is typically around two and a half inches, each eye sees different pictures.
Therefore, the retinal disparity is a binocular cue for depth perception.
