Answer: A. ancestral trait
Explanation:
Bipedalism can be define as a form of terrestrial locomotion, in which the organism moves with the help of two rear limbs or legs. Typical bipedal movements includes the hoping, running and walking. The evolution of the human bipedalism occurred in primates in about 4 million years ago with Sahelanthropus (oldest human ancestors or African Apes). The human ancestor Sahelanthropus led to the morphological alterations in the human skeleton including changes in the bones such as size of the bones of the foot, knee size, shape and orientation of the vertebral column, and leg length. All these changes contributed to the bipedalism.
Answer:
Answer of the question is explaine dbelow.
Explanation:
Rho GTPases interact with a variety of effectors to control actin cytoskeleton
reorganization, cell shape, and cell polarity. RhoA regulates cell shape and adhesion by
the assembly of contractile actin microfilaments into stress fibres. Rho GTPases also
regulate proliferation and cell-cycle progression, especially GuS transition.
All the cells are about to enter mitosis means they cross GuS transition, a drug that is a
potent inhibitor of RhoA activity has no affect on the cell because these cells already in
G2 phase. So, all the cells appear to be in telophase.
So, the correct choice is A. all the cells appear to be in telophase.
Answer:
D) Endocrine system
Explanation:
In some cases, the nervous system directly stimulates endocrine glands to release hormones, which is referred to as neural stimuli.
