Potential evapotranspiration is higher in the summer, on less cloudy days, and closer to the equator, because of the higher levels of solar radiation that provides the energy for evaporation. Evapotranspiration is the sum of evaporation and plant transpiration from the Earth's land and ocean surface to the atmosphere. Evaporation accounts for the movement of water to the air from sources such as the soil, canopy interception, and water bodies. Transpiration accounts for the movement of water within a plant and the subsequent loss of water as vapor through stomata in its leaves.

Answer:
The correct answer is - operation of reflex arc.
Explanation:
The reflex arc is a unique and special type of neural pathway that starts with a sensory neuron and ends with a motor neuron. In this operation sensory neuron acts as the receptor and motor neuron is effector. This type of neural circuit helps in faster response.
Voluntary muscles like quadriceps muscle are normally in control voluntarily however, such muscle may contract involuntary due to reflex arc. This type of contraction takes place before the signal has even reached the brain.
In this response the sensory neuron takes the signal to the spinal cord and then motor neuron to the effector muscle for faster response.
Thus, the correct answer is - operation of reflex arc.
The statement which is true about the scientific method is that "it is important to follow each step in order so the results are valid." Thus, the correct option is C.
<h3>What is the Scientific method?</h3>
The scientific method may be characterized as an approach to investigation in which a problem is determined, appropriate data are collected, an assumption is composed of these data, and the hypothesis has been empirically experimented with.
Scientific methods always deal with a scripted format of identifying the problem, making a hypothesis, collecting the data associated with a hypothesis, synthesizing a methodology, observing it, and making a conclusion.
Therefore, the correct option for this question is C.
