When a nerve impulse reaches the end of an axon of a neuromuscular junction, calcium flows ______ the synaptic knob.
Answer: flows INTO the synaptic knob.
When a nerve impulse reaches the end of an axon of a neuromuscular junction, calcium flows into the synaptic knob.
In a neuromuscular junction, there are three parts. They are the presynaptic terminal or synaptic knob, the synaptic cleft and the postsynaptic terminal. The calcium ions will work in the synaptic knob when the nerve impulse arrives.
Once that the nerve impulse reaches the end of the axon, it will affect the presynaptic terminal. In there, it causes the opening of voltage-gated calcium channels. As a result:
Calcium flows into the presynaptic terminal.The calcium makes the vesicles (with neurotransmitters) descend and fuse with the terminal membrane to release the neurotransmitters to the synaptic cleft.In conclusion, the nerve impulse causes the opening of voltage-gated calcium channels, and calcium flows into the synaptic knob.

which hormone released from the hypothalamus regulates gonad function?
the type of reproduction by which offspring arise from a single organism, and inherit the genes of that parent only.
Explanation:
A single parent reproduction is called Asexual reproduction
Asexual reproduction is a form of reproduction in which the number of chromosomes or the fusion of gametes is not altered.
What is asexual reproduction?The whole gene pool of their single parent is inherited by the children that are produced by asexual reproduction from either unicellular or multicellular organisms.
With asexual reproduction, just one parent is necessary, two parents participate in sexual reproduction, which results in children with distinct genetic makeup.
A diploid zygote is created during sexual reproduction when two haploid gametes combine during fertilization, budding is an example of asexual reproduction.
Therefore, with asexual reproduction, just one parent is necessary.

compared to parasympathetic ganglia, sympathetic ganglia are __________.
Compared to parasympathetic ganglia, sympathetic ganglia are autonomic ganglia of the sympathetic nervous system that prepare the body for emergency situations, such as: defense or flight reactions to a dangerous situation.
In the parasympathetic ganglia, the axons of neurons are characterized by being very long and reach the very structure of the target organ before making contact with the second neuron.On the other hand, these ganglia activate the parasympathetic system that has to do with energy recovery situations such as: activating digestive secretions, reducing blood flow to the brain, which causes drowsiness.In the sympathetic ganglia, axons originate from neurons located in the lateral horns of the spinal cord and exit through the anterior roots of the spinal nerves, along with those of the motor neurons.These ganglia activate the sympathetic system that prepares the body for dangerous situations causing: increased heart rate, blood pressure, respiratory rate, etc.Therefore, we can conclude that compared to parasympathetic ganglia, sympathetic ganglia are autonomic ganglia of the sympathetic nervous system that prepare the body for emergency situations.

The sympathetic nervous system's stimulation response is balanced by the parasympathetic nervous system's ________ response.
Answer: akinesia
Explanation:because it’s a nervous system
The sympathetic nervous system stimulation response is balanced by the parasympathetic REST and DIGEST response.
The autonomic nervous system (ANS) is divided into the parasympathetic nervous system and the sympathetic nervous system.The parasympathetic nervous system is responsible for normal body functioning and homeostasis, whereas the sympathetic nervous system deals with the fight, flight, or freeze responses.The parasympathetic system promotes rest-and-digest activities when the body is at rest.In conclusion, the sympathetic nervous system stimulation response is balanced by the parasympathetic REST and DIGEST response.

What Endangered Species Act, as a vulnerable species?A species that is endangered is one that is in danger of going extinct. The two main factors that cause a species to become endangered are habitat loss and genetic diversity loss.
Natural occurrences may result in habitat loss. For instance, dinosaurs had their home removed some 65 million years ago.
A species that has been designated as vulnerable by the IUCN is one that is predicted to go extinct unless the conditions that jeopardize its existence and reproduction change.
