Answer:
These group of muscles called erector spinae muscles arises from a tendon in the sacral area and pelvis, it extends up to the occipital bone.
Erector spinae muscles originates from the SPINOUS PROCESSES of T9-T12 of the thoracic vertebrae and inserts into the SPINOUS PROCESSES of T1-T2 of the cervical vertebrae
They therefore run vertically on either side of the spine (medially and laterally).
Answer:
my best guess would be d. genetic
Explanation:
because genetic diversity measures genetic variation within species.
Lasting genetic similarities make the two bears biological sister species, more closely related to one another than to any others. ... But Ursus maritimus has also evolved to match its polar environment, growing a longer snout than brown bears' and larger, paddle-like paws, both of which aid polar bears in hunting seals.
The reproductive isolating mechanism most likely responsible for the divergence of bonobos and chimpanzees is ECOLOGICAL ISOLATION.
The ecological mechanism of reproductive isolation is also known as TEMPORAL ISOLATION or HABITAT ISOLATION. This includes the barrier for reproduction that leads to isolation such as different habitats or any physical barriers.
(D) The gene that controls production of white blood cells.
