<span>The (a) resting membrane potential is a result of different concentrations of Na+ and K+ ions inside and outside the cell. A nerve impulse causes Na+ to enter the cell, resulting in (b) depolarization. At the peak action potential, K+ channels open and the cell becomes (c) hyperpolarized.</span>
I think the correct answer is F.
Explanation: Not all ladybugs are born with spots, the dots are a warning to predators that they are toxic. They get the spots when they need them to protect themselves.
The variation that involves contracting each muscle group repeatedly with progressively less tension with each contraction is incremental muscle relaxation.
<h3>What is incremental muscle relaxation?</h3>
Incremental muscle relaxation is a type of variation during a physical exercise aimed at relaxing the muscles.
Incremental muscle relaxation is a fundamental component in any training exercise program.
Incremental muscle relaxation consists of relaxing certain groups of muscle fibers that have undergone rhythmic contractions.

Answer:(B) decrease protein production
Explanation: nitrogen gas in the atmosphere is the source of nitrogen which is useful to plants.
In the nitrogen cycle, nitrogen gas is converted to it's compounds and then back to it's gas form.
The nitrogenous cycle involves fixation, mineralization, nitrification and denitrification .
In the first three states, nitrogen undergoes changes into a state where it can be absorbed by plants.
In denitrification,nitrates (useful form of nitrogen) are converted into gaseous nitrogen.organisms involved in this process are called denitrifying bacteria eg Pseudomonads sp.
Nitrogen is an important element.
It is useful for the production of protein, DNA, RNA and chlorophyll.
When it is deficient in the soil,it affects the synthesis of proteins and yellowing of leaves due to decrease in chlorophyll
