meriva

Answer:

Explanation:

motor neuron is the neuron that have it's connection to a muscle at the neuromuscular junction,. At his junction, a synaptic cleft that has a motor end plate is formed by the activity of the terminal called "synaptic terminal". Diffusion of the acetylcholine across the synaptic cleft then occur which result to the sarcolemma been depolarized, as a result of the depolarization there is a output of Ca2+ and muscle contraction

The effect that botox have on the neuromuscular junction and its function is that there is interaction between Botox and neural transmission which obstruct the acetylcholine to be released, which result to paralysis of muscle.

Which statements describe the effects of the solar wind on Earth? Check all that apply. The solar wind produces the northern and
Andrei [34K]

The correct answers are:

• The solar wind produces the northern and southern lights

• The solar wind disrupts communication systems.  

• The solar wind distorts Earth's magnetic field.

Solar winds are geomagnetic stream of charged particles radiated from the outer atmosphere of the sun. All planets are protected from solar winds via magnetic fields but planets that are positioned closer to the sun can experience degeneration of the magnetic field.

Solar winds are capable to distort and even destroy the functioning of communication satellites  in outer space, such as radio and tv communication and satellite based internet services.

The effects of solar winds that are visible to naked eye are the Aurora Borealis (the Northern lights) and the Aurora Australis (the Southern Lights).

the genes stc1 and stc2, which share a common ancestor, are found in both zebrafish and humans. all four stc genes display simil
Temka [501]

Based on these facts, we can state that the genes of the two organisms had a eukaryotic origin.

We can arrive at this answer because:

  • Despite having exons, prokaryotes do not have introns in their genomes.
  • This means that if two organisms have the same sequence of introns and exons, they have a common ancestor, in addition to having their genes originated in a eukaryotic organism, which explains the sequence of introns.

This means that the genetic expression of these two organisms has similarities, even if they are organisms with different biological processes.
