Answer:
B. physics and engineering
Explanation:
Biomechanics is the study of mechanical laws and living organisms. Hence, it comprises of the interrelationships between physics and engineering.
CORRECT ANSWER:
a- Cell-surface receptors bind polar signaling molecules; intracellular receptors bind nonpolar signaling molecules.
STEP-BY-STEP EXPLANATION:
The complete question from book is
According to Figure 9.6, what is a key difference between cell signaling by a cell-surface receptor and cell signaling by an intracellular receptor?
a- Cell-surface receptors bind polar signaling molecules; intracellular receptors bind nonpolar signaling molecules.
b- Signaling molecules that bind to cell-surface receptors lead to cellular responses restricted to the cytoplasm; signaling molecules that bind to intracellular receptors lead to cellular responses restricted to the nucleus.
c- Cell-surface receptors bind to specific signaling molecules; intracellular receptors bind any signaling molecule.
d- Cell-surface receptors typically bind to signaling molecules that are smaller than those bound by intracellular receptors.
e- None of the other answer options is correct.
Explanation:
Since it is mentioned that the block is in equilibrium, this means the resultant force is zero, and all the forces cancel out each other.
You have to think it in a way so that, the forward force cancel out the backward force. Check the picture attached, on the forward side,
3N + 5N = 8N which cancel out the backward force of 8N
