Answer:
The muscle's insertion
Explanation:
The moveable end of the muscle that attaches to the bone being pulled is called the muscle's insertion, and the end of the muscle attaches to a fixed (stabilized) bone is called the origin.
Answer: D. Contractility of the heart muscle refers to the force of contraction that this muscle can exert.
Explanation:
The myocardial contractility is ability of the heart muscles to contract. This is achieved by the forces which develop between the contracting muscles caused by the filaments of actin and myosin.
The degree of binding of the muscle filaments dependents upon the calcium ion concentration. These actions are controlled in vivo by the sympathetic nervous system. It is driven by the release of the catecholamine, which is a process which determines the calcium ion concentration inside the cytosol of the muscles of the heart.

Answer:
A) bind to receptors in the nucleus of their target cells.
Explanation:
Steroid hormones are synthesized from cholesterol and are lipids, therefore they cannot be transported in the blood dissolved in the plasma. They are associated with transport proteins to travel in blood.
Because they are lipids, they can diffuse through cell membranes, and once inside the target cell they bind to receptors in the cytoplasm or the nucleus and alter gene expression.
