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
There are two events,
A: the selection belongs to the specific species, or
A' : the selection does not belong to the specific species.
c proteins .. most used cuz it provides energy and builds muscle
Global warming affects the spread of animals because different areas will become suitable for different species, so they spread out. This can cause diseases to spread, as the animals may bring them with them. This can also happen in the opposite direction, where the climate change causes less habitats to be suitable for animals, so they become more sparse
Eugene is running and needs more energy. He drinks a sports drink with sugar, but that sugar needs to be converted to another form of chemical energy forhis leg muscles to be able to use it. The process that will convert the sugar to energy that his cells can use is cellular respiration
hope it helps
