Answer:
B) mitochondria
Explanation:
Muscle cells require energy in very high amount because most of the time they are involved in mechanical work i.e. movement and for movement we require large amount of energy. Also, we know that mitochondria are the 'powerhouse of the cell' because they are involved in ATP production which serves as energy source in our body. They are able to produce ATPs with the help of ATPase pump which are located in inner mitochondrial membrane. So, cells found in the active muscles of animals must have large amount of mitochondria so as to perform their function efficiently.
The answer is squamous cell carcinoma. This is a type of
cancer where in one cause of this for it to occur is due to exposure of the sun

Most organisms,
including humans, need to maintain a certain pH within a fairly, narrow range
in order to sustain life. This is achieved through a compound called buffer
that can resist changes in pH, which is key to maintaining stable hydrogen
ions. For instance, human blood needs to keep its pH at around 7.4 so human can
survive.
