Answer: soil tests are most useful during the growing season to monitor plant nutrient uptake.
Explanation:
Answer:
A presynaptic neuron knows when and how much of a certain neurotransmitter it has to release into the synapse by the frequency of the action potential.
Explanation:
Two nuerons connect to each other through synapse. When an action potential, or nerve impulse, arrives at the axon terminal, it activates voltage-gated calcium channels in the cell membrane, then the calcium which is present in hi highconcentration outside the neuron than inside, rushes into the cell. The Calcium then allows synaptic vesicles to fuse with the axon terminal membrane, releasing neurotransmitter into the synaptic cleft.
The nuerotransmitter than binds to the receptors at the post-synaptic cleft and causes the opening or closing of the channels, hence, depolarizing or hyperpolarizing the cells.This can produce a change in the membrane potential—voltage across the membrane of the receiving cell.
Answer:
All living organisms are made up of one or more cells, which are considered the fundamental units of life. Even unicellular organisms are complex! Inside each cell, atoms make up molecules, which make up cell organelles and structures. In multicellular organisms, similar cells form tissues.
Explanation:
Answer:
Those individuals survive which are the best ones and are adapted to their environment. Their survival is due to the possession Of adaptations.
Explanation:
Those organisms which are survive in the harsh environment, it is mainly due to some adaptations which helps them to survive in an environmental condition which are not suitable for them and those organisms are removed from the environment which have no adaptations capabilities.
Answer:
because cell B has more energy demand that Cell A so it will have more mitochondria
