The answer is Na + is entering the cell and the K + is leaving, during the depolarization phase of the action potential open Na + channels allow Na + ions to diffuse into the cell. This inward movement of positive charge makes the membrane potential more positive. The depolarization phase is a positive response sequence where open Na + channels cause depolarization which in re-occurrence causes more voltage gated Na+ channels to open.
I believe it is a combination of polygenic inheritance and environmental factors. Several genes control the height in humans, giving an overall normal distribution. Environmental factors on the other hand such as nutrition smooth out the curve. It is therefore important to note that Human height is a quantitative, or metric trait, that is, a characteristic that is measured in quantity, and is controlled by multiple genes and environmental factors.
NITROGEN FIXING BACTERIA processes nitrogen in the atmosphere and make it available to other living forms in a usable form. Nitrogen fixing bacteria are micro organisms which are capable of transforming atmospheric nitrogen into fixed nitrogen. An example of a nitrogen fixing bacteria are bacteria in the genera azotobacter.
The main goal of ecological succession is "development of new species".
<u>Option:</u> A
<u>Explanation:</u>
The mechanism of transformation of an ecological community's species structure over time is understood as "Ecological succession". The timeframe can be decades like a wildfire after a mass extinction, or even millions of years.
Succession can either be caused by the development of new, unused habitat, perhaps from a lava flow or a severe landslide, or through some form of community disruption, such as from a fire, extreme windthrow, or deforestation. It is not in equilibrium as a group undergoes numerous changes across each stage of succession.
Livestock candidates should be chosen based on the patient's preference as there could be organ rejection is an unbiased argument.
<h3>What is an Unbiased argument?</h3>
This type of argument shows the reader both sides and bids the reader decide.
The other options tends to support an animal which makes them biased but option D doesn't and has a credible reason which is why it's the most appropriate choice.
