This is the answer hope it helps, have a good day
Answer:
adenosine triphosphate
Explanation:
Your energy does come from food, but not directly. All cells, like that in Figure 1.1, use chemical energy carried by ATP— adenosine triphosphate. ATP is a molecule that transfers energy from the breakdown of food molecules to cell processes.
(a) very frequent use of something so that it stops being effective; an over-use.
Answer:
1.Continuous diffusion of negatively charged ions into the postsynaptic neurons , <u>which leads to continuous reversal of charges (hyperpolarization) and therefore continuous firing of action potential</u>
2. Inhibition of hydrolytic enzymes e.g (acetycholinesterase) that metabolize activities of cholinergic neurotransmitters e,g acetycholine at post synaptic cleft. leading to firing of action potential.
Explanation:
Neuron whose dendrites transmits action potential to the neuromuscular junction is called presynaptic neuron. While neuron that transmit action potential away from the neuronal synaptic junction, or from the neuromuscular junction to the cell body of adjacent neuron or to effectors (gland and muscles) are called post synaptic neuron.
The more negatively charged ions that diffused into the post synsptic neuron, the more depolarization, and the greater the frequency of action potential produced
The inhibition of activities of hydrolytic enzyme which metabolize cholinergic neurotransmitter leads to continuous excitatory activities of cholinergic neurotransmitters on the receptors at the postsynaptic neuron, and the more action potential
Answer:
Ocean circulation patterns is directly linked with the marine ecosystem. El Nino event hinders the climate interaction of ocean.
Explanation:
- The disturbance in the ocean climate interaction transfers the essential nutrients into the deep down ocean leaving very tiny amount at the surface. It lacks the support to plankton growth.
- Ocean circulation patterns can sometime make the ocean food ecosystem less productive.
- El Nino event reverses the ocean current. Surface waters in the central and eastern Pacific Ocean become significantly warmer than usual during this event. So the drifting starts towards east direction (normally driven west).
