The uniqueness of individual offspring for many animals and plants is the result of a process called Meiosis.
During meiosis , the number of chromosomes in parent cell are reduced by half and produces four gamete cells.
Later
on, these chromosomes are mixed into the new offspring, causing it
carried out some characteristic from its parents and became a new unique
individual.

Answer:
Trapezius.
Explanation:
Sternocleidomastoid muscles may be defined as one of the largest superficial cervical muscle. The main function of this muscle is the neck flexion and the head rotation.
Trapezius muscle is the large muscle that extend from the occipital bone. The main function of the trapezius muscle is the scapula movement and support of the arm. Trapezium muscle resist the neck flexion and works as the antagonist to the trapezius muscle.
Thus, the answer is trapezius.
Answer:
The correct answer is - per gram, the marathon runner's muscles would contain more myoglobin than the sprinter's muscles.
Explanation:
Marathon runners have smaller leg muscles and thinner quads and calves as marathon runners require slow-twitch muscles while in sprinters the fast-twitch muscle requires. Slow-twitch muscles of marathon runners have more amount of myoglobin, per gram than fast-twitch muscles.
Myoglobin acts as local oxygen storage that provides oxygen to the muscles in case of less oxygen supply than required temporarily and a marathon race is an intense exercise or activity that requires more oxygen.
