Answer:
Answer : Depolarized
Explanation:
Sodium and Potassium ions tend to move inside of the axin when the membrane is depolarized.
A change in polarity occurs in the axon membrane when a nerve impulse travels across it. At the beginning of an action potential or nerve impulse , the ions of sodium tend to move inside of axon causing depolarization. As a result potassium ions tend to move outside of the axon causing re polarization. Hence, this effect causes the nerve impulse to travel in one direction only inside the axon.
Answer:
According to the theory of evolution by natural selection wolves with mutations will outgrow the wolves without mutation.
Explanation:
Nature always poses challenges to the living organisms in various forms like climate change, food scarcity, natural disasters, etc. If an organism has a characteristic to survive better than the other, then they will be selected by the nature. We can also use the term fitness for this. Darwin also referred about this as reproductive fitness which means only those organisms which are fit in their environment produce more progeny and increase in number. s we can see that the introduction of mutation has added the advantage of being faster and stronger, so when it comes to competition for food the wolves with mutation can easily catch the predator than wolves without mutation. Since mutation has resulted in better adaptation to their environment they will outgrow in number.
There should be options for this question. I manged to find them elsewhere. They are:
A) the period during which tremendous growth occurs and the organs continue to develop and become functional
B) the period during which the umbilical cord develops
C) the period during which the major organs and structures of the organism first develop
D) the period during which the zygote moves down to the uterus and begins to implant in the lining
The correct answer is C. The embryonic period is the period during which the major organs and structures of the organism first develop. The embryonic period lasts from implantation of the egg in the uterus until about 8 weeks from the time of conception. It is the second major stage of prenatal development, prior to embryonic is the germinal stage and lastly is the fetal stage.
