The cardiac muscle is only in the heart because it has special characteristics such as being able to make sustained contractions, coordinated movement, and rapid conduction. Hope this helps!
Skeletal muscle or striated muscles is an important part of the human motion system. These muscles will contract and relax so as to move the bones in the body movement.<span>Bones as a means of passive motion was not able to move without the muscle as a tool motion.</span>
At room temperature and normal atmospheric pressure, covalent compounds may exist as a solid, a liquid, or a gas, whereas ionic compounds exist only as solids, Ionic compounds exist in stable crystalline structures. Therefore, they have higher melting and boiling points compared to covalent compounds.
It is called Commensalism.
The shark is neither harmed or benefited but the remoras get the benefit of this relationship without harming the shark.
Answer:
exposure to ultraviolet radiation is a correct answer.
Explanation:
Ultraviolet light exposure results in the formation of pyrimidine dimers. Ultraviolet radiation damage the DNA by resulting in chemical changes.
Ultraviolet radiation is absorbed by the pyrimidine bases( cytosine and thymine in DNA) and result in the formation of covalent bonds between the succeeding bases.
The formation of the pyrimidine dimers results in the distortions of DNA helix and disrupt the base-pairing during the replication of DNA which results in a mutation.
