Answer to *This is the generation that produces the offspring.*
Parent
Answer:
membrane potential reaches threshold
many voltage-gated Na+ channels open
Na+ ions rush into the cell
membrane potential rises
Explanation:
During resting condition, the axon membrane is polarized and has a voltage of -70mV. However, when action potential occurs after reaching the threshold level (voltage is equal to -55mV) after which the axon membrane first depolarizes and then polarizes again to reach the initial resting state. The threshold potential open the sodium voltage gates channels thereby allowing sodium ions to enter into the cell. As the sodium ion enters the cell, the membrane potential become less negative. When the membrane potential reaches the mark of +30mV, the sodium gated channels closes and potassium voltage gated channel opens.
Answer:
Plants go through a process called photosynthesis that allows them to take carbon dioxide out of the air and turn it into oxygen and energy. The oxygen will later be breathed in by an animal and go through cellular respiration where it will become CO2 again.
Answer:
<em>The correct options are B and C</em>
Explanation:
Option A is false because bacteria fix nitrogen by converting it into ammonia. The ammonia is used by the plants for different functions like development etc.
Option B is correct because plants can take up both ammonium ions and nitrate ions from the soil. They use these ions to make amino acids which are required by the plant for different activities.
Option C is correct because nitrifying bacteria are the bacteria which convert ammonia into nitrites and then nitrates in a process which is termed as nitrification.
Option D is false because herbivores eat plants to make amino acids and proteins.
