When river water<span> meets </span>sea water<span>, the lighter </span>fresh water<span> rises up and over the denser </span>salt water<span>. </span>Sea water<span> noses into the estuary beneath the outflowing </span>river water<span>, pushing its way upstream along the bottom. Often, as in the Fraser </span>River<span>, this occurs at an abrupt </span>salt<span> front</span>
The answer is <span>C) mosses, lichen, grasses, and small shrubs.
This is because mosses don't have roots and are very simple plants, therefore they don't have to "root" themselves into a permanently frozen ground that can't support them.

Answer:
True
Explanation:
When the resting potential of the membrane is changed, the membrane becomes either more negative inside or less negative. This small deviation from the resting potential is called graded potential. A graded potential occurs when a stimulus triggers opening or closing of the mechanically gated or ligand-gated channels present in the plasma membrane.
For example, the presynaptic neuron releases neurotransmitters in response to a nerve impulse. The neurotransmitter binds to receptors present in the plasma membrane of the postsynaptic neuron and triggers the opening of the ion channels to allow the inflow of particular ions to flow. The flow of ions changes the voltage across the membrane. This change in membrane voltage is a postsynaptic potential and is a type of graded potential.
Answer:
The amount would certainly be higher because with blood doping or in other words blood transfusion, there will be more red blood cells which means more oxygen carrying cells, more exchange of oxygen in the alveoli, more oxygen dilivery to muscles for them to use for ATP productiona.
