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.

What percentage of body water loss can impact athletic performance?
the small bones in the middle ear that transmit vibrations to the inner ear
Answer:
, yes..............
Explanation:
because the vibrations are transmitted to the inner ear after the bones amplify it
Ossicles are the body's tiniest bones. the malleus (hammer), incus (anvil), and stapes (stirrup). Ossicles amplify sound.
What are ossicles?Ossicles are very little bones; in fact, they are the tiniest bones in the entire human body. The malleus (hammer), the incus (anvil), and the stapes are the names of the three bones because of the forms they make (stirrup). The sound is amplified even further by the ossicles.
In order to reach the eardrum, sound waves must first enter the outer ear and then proceed via the ear canal, which is a very short conduit. The incoming sound waves cause the eardrum to vibrate, and the eardrum in turn transmits these vibrations to three very small bones located in the middle ear. The malleus, incus, and stapes are the names given to these three bones.
Hearing is dependent on a series of intricate steps that convert sound waves in the air into electrical impulses. These steps are necessary for hearing.

Each nucleosome is composed of a little less than two turns of DNA wrapped around a set of eight proteins called histones, which are known as a histone octamer. Each histone octamer is composed of two copies each of the histone proteins H2A, H2B, H3, and H4.
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.

True/False: In a neuron at rest, the concentration of sodium ions is 14 times higher outside the cell than inside the cell.
Answer:
true
Explanation:
The sodium and chloride ion concentrations are lower inside the cell than outside, and the potassium concentration is greater inside the cell. These concentration differences for sodium and potassium are due to the action of a membrane active transport system which pumps sodium out of the cell and potassium into it.

in the gel electrophoresis lab, you determined the ________ of three different dna samples.
In the gel electrophoresis lab, you determined the genotype of three different DNA samples.
Gel electrophoresis is a process that allows you to separate fragments of DNA based on size. You place different size fragments of DNA into a gel, then apply current to the buffer surrounding the gel, the DNA will travel through the gel but move at different speeds based on the different fragment sizes. Larger fragments of DNA will move slower than smaller fragment sizes.
Let consider two different alleles:
the bigger allele -- Athe smaller allele -- aThe bigger allele happens to contain a restriction site that is allowed to be cleaved by a restriction enzyme while the smaller allele has a mutation in the restriction site that means that it will not be recognized and cleaved by that same restriction enzyme.
Let us remember that the person will have two copies of this gene and can be:
H0m0zygous dominant AAh0m0zygous recessive aaheterozygous AaAn individual with h0m0zyg0us AA only have versions of the gene that will be cut by the restriction enzymes, each allele producing a small fragment of DNA and a medium-size fragment of DNA
An individual with the genotype aa only has the version of the gene that does not have the restriction site and therefore does not get cut by the restriction enzyme. The DNA sample from this individual will have a single larger fragment of DNA.
When you isolate DNA from heterozygous Aa, half of the DNA isolated has the allele with the restriction site that gets cut into two fragments while the other half will have the allele that does not have the restriction site and remains whole when a restriction enzyme is added.
Therefore, we can conclude that in the gel electrophoresis lab, you determined the genotype of three different DNA samples.
