it allows for nutrients to come into the cell using passive tranport aka moving anything on a gradient without the use of energy (ATP).
Answer: B
Condensation is a process via which a liquid directly converts to a gaseous state, skipping the liquid state altogether. Therefore, a very cloudy sky is an example of water being converted to gaseous state directly.
A motor unit consists of <u>a single motor neuron</u>.
<h3>What is a motor unit?</h3>
Most mature extrafusal skeletal muscle fibers in mammals are innervated by only a single alpha motor neuron. Since there are more muscle fibers by far than motor neurons, individual motor axons branch within muscles to synapse on many different fibers that are typically distributed over a relatively wide area within the muscle, presumably to ensure that the contractile force of the motor unit is spread evenly .
In addition, this arrangement reduces the chance that damage to one or a few alpha motor neurons will significantly alter a muscle's action. Because an action potential generated by a motor neuron normally brings to threshold all of the muscle fibers it contacts, a single alpha motor neuron and its associated muscle fibers together constitute the smallest unit of force that can be activated to produce movement.
Sherrington was the first to recognize this fundamental relationship between an alpha motor neuron and the muscle fibers it innervates, for which he coined the term motor unit.

Answer down below:
During mitosis, the cells duplicate by also duplicating DNA. In this instance, cells A and F are in the process of prophase, in which the chromosomes starts to form. Hope this helps!
Answer: Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions.
