Which of these transport processes is the major means by which Na+ is transported across the membrane of neurons? Why?

A) both II and III because the activity of the neuron varies
B) I because Na+ is so small it can freely diffuse into the cell
C) III because Na+ is actively transported out of a neuron to maintain extracellular concentration
D) II because Na+ is charged and cannot cross the hydrophobic interior space of the cell membrane

Genes and amino acid sequences.

Explanation:

The ancestor of whales and hippos are the same because of the same gene and amino acid sequence. The genes and amino acid sequences of living whales were the evidence that shows ancestry of whales and hippos. This evidence indicates that million of years ago both whales and hippos were split from a same ancestor due to evolution.

A forest ecosystem is more stable than a potato field.

Explanation:

The forest ecosystem is a natural one and all the elements are balanced, they are managed by the nature itself.

The forest ecosystem is a natural one, and all the components are in harmony since nature herself manages the ecosystem.

Thus, A forest ecosystem, or simply a forest, is a community of plants, animals, microorganisms, and other species that interact with the chemical and physical elements of their environment.

The species in a forest ecosystem are depending on one another in order to survive, and they can be roughly categorized as producers, consumers, and decomposers based on their ecological roles.

The boreal forest that surrounds the Earth in northern latitudes is an example of a vast forest ecosystem. A forest ecosystem can also be as small as a microsite on a tree limb where mosses, insects, and microscopic species coexist.

Thus, The forest ecosystem is a natural one, and all the components are in harmony since nature herself manages the ecosystem.

Stream , Tributary, River, and Lake

Explanation:

Stream tributary River and Lake is the path for gravity causes water to move.

Evaporation, condensation, and precipitation are typically taught as three separate but interconnected stages of the water cycle. Although this is a useful model, the actual situation is far more nuanced.

Water moves through ecosystems on Earth in a variety of ways that are incredibly complicated and still not fully understood.

For better weather, climate, water resource, and ecosystem health forecasting, NOAA is working to increase understanding of the water cycle at all sizes, from the global to the local.

Evaporation, condensation, and precipitation are frequently taught as three basic, circular processes that make up the water cycle. This is a good paradigm, but in practice things are much more nuanced.

Therefore, Stream tributary River and Lake is the path for gravity causes water to move.

yy is green (recessive)

with Yy and yy, you could only get 50% Yy(yellow) and 50% yy(green).  There is no way to make only yy or YY, and in order to make 100% Yy you would need one yy and one Yy

The cross between parent plants if one is heterozygous and has yellow-colored pods and the other is homzygous and has green-colored pods -  Yy yy

Purebred genotype:
