C)temperature and rainfall
Explanation:
Temperature and rainfall are the most important physical factors that shapes the characteristics of an ecosystem. 
Temperature is the degree of hotness or coldness of a place. It is mostly as a result of the solar radiation it receives. 
Rainfall is a form of precipitation in which water falls under gravity in liquid form. 
They are both by far the most important factors that shapes ecosystems.

If the results of an experiment have different conclusions, something must have changed. these are called **variables**. if more than one variable is changed, the result would be different. because the total conclusion is different, it is a hypothesis, because it is not universally true.

In an experimental animal model, total renal plasma flow is 100 ml/min. You would estimate glomerular filtration rate to be 20 ml/min.
<h3>What is renal blood flow?</h3>
Renal blood flow is the amount of blood delivered to the kidneys per unit of time in kidney physiology. In a 70-kg adult male, the kidneys receive 1.2 to 1.3 L/min, or about 25% of the cardiac output in humans. 94% of it makes it to the cortex.
<h3>Renal plasma flow V/S Renal blood flow </h3>
Renal blood flow is the measure of blood passing through the kidneys in a given length of time, whereas renal plasma flow is the quantity of plasma passing through the kidneys in a given amount of time. As a result, this is the primary distinction between renal blood flow and renal plasma flow.
<h3>What is glomerular filtration rate ?</h3>
A test called the glomerular filtration rate (GFR) measures how efficiently the kidneys are functioning. It specifically determines the amount of blood that is pumped through the glomeruli per minute. The kidneys' globuli are microscopic filters that remove waste from the blood.
