During depolarization, which of the following statements about voltage-gated ion channels is TRUE

Biology
1 answer:
Wewaii [24]3 years ago
5 0

Answer:

In relation to voltage-gated ion channels, when depolarization occurs, Na⁺ gates open while K⁺ gates remain closed.

Explanation:

Depolarization is a phenomenon that occurs in cells like neurons, and depends on the distribution of ions in extracellular spaces and intraceluar.

  • Na⁺  is a predominantly extracellular cation.
  • K⁺ has a high intracellular concentration.

This distribution occurs when the membrane potential is at rest, with a negative intracellular value.

Depolarization involves opening the Na⁺ channels, so that this cation enters the intracellular space, causing a change in cell voltage. Increasing Na⁺ concentration in intracellular space progressively produces an action potential, resulting in an electrical signal.

While depolarization occurs, K⁺ channels remain closed, limiting the output of this cation to extracellular space, which would prevent the action potential from occurring.

PLEASE HELP ASAP!
Vlad [161]

Answer: Maybe if you knew the def's you could answer it.

Initial Decay – Bacteria located mainly in the lower intestine begin decomposition, giving a greenish color to the lower abdomen. Stage 2: Putrefaction – Bacteria grow throughout the body, releasing gases, including cadaverine, which in turn bloat the body and cause unpleasant odor.

putrefaction

the process of decay or rotting in a body or other organic matter.

Black putrefaction occurs, which is when noxious odors are released from the body and the parts of the body undergo a black discoloration. 2 weeks: The abdomen is bloated; internal gas pressure nears maximum capacity. 3 weeks: Tissues have softened. Organs and cavities are bursting.

Fermentation occurring in putrefaction and apparently in the digestion of herbivorous mammals in which butyric acid is produced by certain chiefly anaerobic bacteria acting upon various organic substances (such as lactic acid or butter)

A dry body will not decompose efficiently. Moisture helps the growth of microorganisms that decompose the organic matter, but too much moisture could lead to anaerobic conditions slowing down the decomposition process

Wich of the following describes a mendelian trait?
baherus [9]

Answer:

Option C

Explanation:

A Mendelian trait is a dominant allele a offspring can receive from it's parents. Dimples or freckles are main examples of mendelian trait's because it's a dominant phenotype you can receive from your parents. Therefore the answer is option C or "humans can have dimples or not have dimples."

Hope this helps.

Which of the following is the most powerful evolutionary force in large populations over time?
DanielleElmas [232]
There is no answer that is right except for C. Natural Selection.

Genetic Recombination doesn't change gene frequency;nor does migration. (Unless it's local)

Mutation could be the answer, but since mutations are too rare to really power Evolution, the only logical answer is Natural Selection.
