Answer:
A <u><em>receptor</em></u> is a protein that recognizes and responds to a signal.
Explanation:
A receptor is a protein molecule present on the cells on which the signalling molecules can bind and generate a physiological response. Some receptor molecules can also respond to Sun and light. Each type of cell has specific receptors molecules and hence can respond to specific signals. The receptor molecules hence tend to receive signals for a cell. Molecules such as hormones bind to the receptors.
Answer:
The bicondylar angle positions the center of mass above the base of support during the single-support phase of bipedal locomotion.
A. True
Explanation:
The bicondylar angle is the functional angle between the diaphysis of the femur, perpendicular to the intercondylar plane. Very unique to humans, this angle places the knee and the foot under the body's center of gravity during a single support phase of locomotion or gait. With hip joints set lateral to the body's midline, the bicondylar angle aligns the lower limb with the center of gravity, thereby facilitating human movement.
