The negative membrane potential in a resting neuron is primarily due to :___________

a. high levels of chloride ions in the cell. diffusion of potassium out of the cell.
b. a higher permeability of the membrane for potassium compared to sodium.
c. both diffusion of potassium out of the cell and a higher permeability of the membrane for potassium compared to sodium are correct.

Answers

Answer 1

Answer:

c

Explanation:

Answer 2

When the membrane of the neuron is in a state of rest, the interior of the cell has a more negative charge in relation to the exterior, therefore option "c" is correct.

What is the membrane potential in a resting neuron?

It is a phenomenon that occurs when the nerve cell membrane is not altered by action potentials.

Characteristics of a resting neuron

The resting potential is determined by the concentration gradients of the ions, both inside and outside the neuron, and by the permeability of the membrane.

When a cell is at rest, the potassium channels are open, the potassium will tend to flow outwards (K ions), they are positive charges, therefore the cell interior will be negative with respect to the cell exterior.

Therefore, we can conclude that the resting potential of a membrane occurs when they are not transmitting signals.

scientist have hypotheses about dark matter but need more data to test ideas
Scientists throughly understand what dark matter is and what it does
Scientists are not convinced that dark matter exists
New data could cause scientist to change their hypotheses about dark matter

Answers

The statements that accurately describe the views of scientists about dark matter are;

Scientists have hypotheses about dark matter but need more data to test ideas.New data could cause scientist to change their hypotheses about dark matter.

Scientists do not really understand what dark matter is but they have ideas about the things it is not.

For instance, scientists know that dark matter is not bright like our planet and the stars. This can be deduced from its name, "dark matter."  

Scientists also believe that dark matter is not composed of antimatter. If it were, they would be able to detect this through the emission of gamma rays.

Scientists have other speculations but if new data comes with convincing proofs, they may have to change their present hypotheses.

Explanation:

To solve this we must be knowing each and every concept related to ecosystem. Therefore,  an environment with a large variety of plant and animal species is the correct option.

What is ecosystem?

An ecosystem is generated through the interaction of all life forms with each other as well as with the chemical and physical features of their surroundings, all of which are linked by the energy flow. It includes all of the living organisms in a given region in addition to their non - living things surroundings such as air, water, and sunshine.

Humans depend on ecosystems to meet their fundamental requirements. Ecosystems sustain us by providing safe drinking water as well as nutritious food. They supply raw materials for our clothes, housing, transportation, and energy needs.  An environment with a large variety of plant and animal species is more sustainable ecosystem.

of the two cells represented in the figure, which would likely be more efficient at exchanging substances with the surrounding environment?

Answers

Cell A is more efficient at exchanging substances due to larger surface area to volume ratio.

Cell A is more efficient at exchanging substances with the surrounding environment than cell B because it has the larger surface-area-to-volume ratio. Larger surface area of the cell exchanges more substances with the surrounding environment.

While on the other hand, lower surface area of the cell exchanges less materials with the environment so we can conclude that cell A is more efficient at exchanging substances due to larger surface area to volume ratio.
