Answer:
A.Testable hypotheses
it makes the most sense out of the rest
In some skeletal muscles, the
fascicles form a common angle with the tendon. These skeletal muscles are known
as Pennate muscles (also called pinnate muscles or penniform muscles). Generally,
these types of muscles allow higher force production but smaller range of
motion.
They adapt because they can replicate quickly (have many generations within short period of time) and accumulate mutations. Mutations in their genetic information allows them to bypass the host's immune system or resist to antibiotics. These mutations are successfully carried to the next generations of bacteria and allows them to thrive in their new environments. <span />
