It helps move wastes out of the cell and allows water and nutrients to move into the cell
The choice that isn’t an adaption is choice D because although having a moisture-rich diet is essential for birds, it isn’t required for them to obtain this adaptation when living in the chaparral biome. I hope this helps.
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 = 
So a force of 8 N will be required to pull the pulley.
<span>The answer is osteoid. It begins with unmineralized collagen fibers
and ground substance. Later it becomes a calcified matrix. The matrix is mainly
made of collagen and calcium ions. When not well mineralized, osteoblasts proliferates
hence the bone will not have the desired strength. This results to deformation
of bone causing rickets</span>
Answer:
It speeds up the reaction rate
Explanation:
Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.
