Answer:
Generation of ATP in muscle cells.
Explanation:
Mitochonria is the power house of the cells, in this organelle of cell the biochemical process of respiration and generation of energy occurs. Energy produces in the form of ATP.
Mitochonrial DNA coded for specific protein complexes which are responsible for the process of electron transport chain and ATP synthase. If in the mitochondrial genes mutation occurs it will affect the production of ATP (energy) in muscle cells.
Answer:
a. nails are a scalelike modification of the stratum corneum layer of the epidermis
b. nails form on the dorsal edges of the fingers and toes
c. fingernails do protect the digits from damage
Explanation:
The stratum corneum consists of the top layer of the epidermis (i.e., skin). Nails represent a modification of the epidermis and they are composed of densely packed dead skin cells (keratinocytes), which are rich in a protective protein called alpha-keratin. The nail plate is the hard keratinized part of the nail. The nail bed is the skin underneath the nail plate. The nails grow from the proximal portion of the nail bed, which is known as the nail matrix. The main function of the nails is to protect the tips of fingers and toes from injury.
Answer:
Decreases
Explanation:
When the energy decreases, the agent of erosion does not nave the power to carry large sediments. It drops them off based on their weight (heaviest first),
They both have seasons caused by a tilted axis
