A root of a cotton plant must
overcome various potential forces such as gravitational forces that pulls water
downward, matric forces where there is an adhesion of water molecules from a soil and osmotic forces where attracting water in the presence of large amount of soluble salts in the mixture of soil.
If the soil were compacted by
a heavy vehicle, the matric forces would be mostly affected for compaction will
result to increase matric forces due to reduced size of pores of the soil
making it more difficult to draw water from a solid surface.
<h2>Membrane potential </h2>
Explanation:
- Membrane potential represents charge difference across the membrane, all biological cells are negative inside (cytoplasm) and positive outside (due to difference in ionic distribution)
- In a typical neuron cell membrane potential of cytoplasm is negative at rest (when no stimulus is applied) hence called resting membrane potential
- Resting membrane potential of excitable cells is established by Na+ and K+pump
- Repolarization starts with the efflux of K+ by the opening of voltage gated K+ channels
- Voltage gated K+ channels starts to open when voltage gated Na+ channels becomes inactive
- Hyperpolarization occurs due to excessive efflux of K+ by voltage gated K+ channels
- Additional efflux of K+ occurs due to slow inactivation of voltage gated K+ channels
Blue light bends more.
The laser would miss and you would need to aim below the fish.
The answer is 0.11. I just did the quiz on Apex.
