Answer:
Ciliary muscle
Explanation:
Muscle that changes the thickness of the eye lens through contractions and relaxations
Answer:
Explanation:
Reproductive isolation must occur so that the gene pools are isolated. When the gene pools are isolated, changes that occur in one gene pool will not be carried over to the other gene pool. Thus, over time, accumulated gene pool changes can produce a new species.

Answer: If this pump quits working (as happens under anoxic conditions when ATP is lost), or if the action of the pump is hindered (as happens with heart glycosides, for example, digoxin), Na+ aggregates inside the cell and intracellular K+ falls.
Explanation:
The way toward moving sodium and potassium particles over the cell layer is a functioning vehicle procedure including the hydrolysis of ATP to give the necessary energy. It achieves the vehicle of three Na+ to the outside of the cell and the vehicle of two K+ particles ions to the inside. In this manner, if the sodium-potassium siphon quits working both Na+ aggregates inside the cell and intracellular K+ falls.
The major organ that you would find in the lymphatic system would be the spleen.
A force of 8 N will be required.
<h3><u>Explanation:</u></h3>
Mechanical advantage is defined as the ratio of output force from a system to the input force into the system. A machine which has the mechanical advantage more than 1 means it requires less force to give more force as output. Similarly, when the mechanical advantage for the machine is less than 1,it means more force is required to give to achieve a less one.
Here in the question, the mechanical advantage of the pulley is 2.
Output force required to pull the sack of potatoes upto kitchen is 16N.
Mechanical advantage = Output force / input force.
Or, 2= 16 / input force.
So input force = ![16 / 2 =8.](https://tex.z-dn.net/?f=16%20%2F%202%20%20%3D8.)
So a force of 8 N will be required to pull the pulley.
