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.
The principle of joint operations that entails expending minimum essential combat power on secondary efforts in order to allocate the maximum possible combat power on primary efforts is called the economy of force. It is one of the principles of war that is based on Clausewitz's approach. The economy of force is the principle where we employ all of the available combat power in a way that is the most effective as much as possible, attempting to allocate a least amount of important combat power to any efforts. It is closely associated to the idea of force concentration. According to this principle, any part of the whole effort should not be left idle.
it's Also called aerobic exercise, endurance exercise includes activities that increase your breathing and heart rate such as walking, jogging, swimming, and biking. Endurance activity keeps your heart, lungs and circulatory system healthy and improves your overall fitness.
