Answer:
This statement is not correct because the Na+ equilibrium potential remains the same, it is only depends on concentration gradient.
Explanation:
Na+ influx will increase, but Na+ equilibrium potential will not change because the concentration of K+ ions are high inside the membrane and that of Na+ ions are high too outside the membrane. Membrane potential will be generated that helps in the diffusion of the ions through the pore in both in and outside of the cell. When the concentration of Na+ ions increase, Na+ ions diffuse from outside to the inside of the cell therefore increase the influx
Answer:
A watershed – the land area that drains to a stream, lake or river – affects the water quality in the water body that it surrounds. ... They are influenced by naturally varying lake levels, water movement to and from groundwater, and amount of stream flow.
Explanation:
Double fertilization happens when one sperm cell wires with the egg to create a zygote, and the other sperm cell wires with the two polar cores to make the endosperm.
To answer the above:
Once double fertilization occurs in plants, the zygote is diploid and the endosperm is <span>triploid.</span>
Hello
The pH range of tolerance for humans is well defined and very small for a number of reasons.
First, we must understand that all biological reactions in our body are carried out by biological catalysts called enzymes. These enzymes operate under specific pH and and temperature conditions. Deviation from these conditions will result in inefficiency of the enzymes' functions. This may be observed macroscopic-ally as poor digestion among other things.
Next, an equilibrium is necessary for the movement of CO2 in red blood cells. CO2 is kept in equilibrium in the form of carbonic acid. This equilibrium may be disturbed by the change in pH; resulting in a difficulty to breathe.
Other effects such as fatigue, headaches and nausea may also be observed as the blood circulates throughout your body and its functions will be impaired by the changed pH.
Accretion is a process by which material is added to a tectonic plate or a landmass. This material may be sediment, volcanic arcs, seamounts or other igneous features. There are two types of geologic accretion—plate accretion and landmass accretion. The Plate accretion involves the addition of material to a tectonic plate. The Landmass accretion involves the addition of sediment to a coastline or riverbank, increasing land area.
