Answer:
E... 126
Explanation:
The appendicular skeleton includes all bones of the upper and lower limbs, plus the bones that attach each limb to the axial skeleton. There are 126 bones in the appendicular skeleton of an adult
Because the organism is distributed across the world, and isn't seen anymore, scientists can conclude tat they must have evolved. They can compare one species to the fossils they may have found, and determine that they were related. Then by looking at the species on another part of the world compare the same fossils to other animals and determine that they are similar, sharing a common ancestor.
According to the research, decomposers are organisms responsible for returning nutrients back to the soil.
<h3>What are decomposers?</h3>
They are different organisms such as bacteria and fungi whose main function is to break down the waste of plants and animals.
With the decomposition process where organic matter is processed into inorganic, simple elements (nutrients) reappear in the soil that are used as food by plants.
Therefore, we can conclude that according to the research, decomposers are organisms responsible for returning nutrients back to the soil.

Answer:
The region where the end of an axon from a neuron comes into close contact with a muscle fiber is called a motor end plate/neuromuscular junctions.
Explanation:
Neuromuscular junction is the connection between end of the axon terminal and the muscle fiber. It is the site of transfer of signal from the neuron to the target muscle. The action potential is generated at the axon terminal which causes the calcium channel to open releasing the neurotransmitters into the synaptic cleft. The acetylcholine which is the neurotransmitter then bind to the receptors on the muscle which opens the sodium channels and it is released into the muscle which causes the depolarization of the muscles. The calcium ions then enters the cells and the muscles contract.
