Answer:
Trait
Explanation:
We call a specific variant of a character a phenotypic trait.
The answer is A- double carbon bond
Answer:
The membrane potential of a nerve cell will depolarize if there is an increase in the positive ions inside the cell.
Explanation:
When nerves are in resting potential it is -70mV. In this stage interior of the cell is negatively charged and outside is more positive. When depolarization occurs the inside cell becomes positive.
This is due to the rush of sodium ions into the cell by voltage-gated channels. Now the inside charge is more positive and the chloride ions move out of the cell. Thus outside becomes more negative.
After some time of depolarization stage, potassium ions move out of the cell making the nerve cell again negative. Now the depolarized stage becomes repolarized by the entry of potassium ions.
During depolarization, the potential of the cell is -55mV. When repolarization occurs, it is again -70mV. But the potassium channels are open and some of the potassium ions move out of the cell making the inside environment more negative. This is known as hyperpolarization condition.
This hyperpolarization remains for a short period where action potential can't occur. This period is called the refractory period. Again potassium ions enter into the cell. This results in the resting potential of the neuron again.
Well one thing u could do is to reduce the amount of fossil fuels burning (idk how, maybe finding a better alternative to burning them) another way would be planting more trees, or buy energy efficient products. Basically these things just reduce the carbon footprint by reducing the amount of fossil fuels (because we only have a limited amount) i hope this helped
Development. there is a branch in biology called Developmental biology<span> is the study of the process by which organisms grow and </span>develop. Moderndevelopmental biology<span> studies the genetic control of cell growth, differentiation and "morphogenesis," which is the process that gives rise to tissues, organs and anatomy.</span>
