Answer: blood calcium level
Explanation:
There are several factors affecting the rate of kidney filtrate formation including filtration membrane integrity
, systemic blood pressure, and renal artery/arteriole diameters.
Filtration membrane integrity
: It regulates the filtration of small fitrates and large filtrates. It is very important to handle the osmotic pressure of salts, if it will get damage the filtration will not take place properly.
Systemic blood pressure: systemic blood pressure is very important factor as it affects the Glomerular Filtration Rate (GFR). Low blood pressure or volume due to dehydration can result in decreased GFR.
Renal artery/arteriole diameters: The filtrate move through the renal artery and if it's diameter will increase or decrease it will affect the movement of filtrate. if diameter will decrease it can block the renal artery and can cause a huge damage.
Blood calcium level do not have any role in the kidney filterate formation or renal regulation.
Hence, the correct option is blood calcium level.
Answer:
The difference in the given case indicates that the results are reliable but not accurate. Precision is the tendency of an apparatus to provide repeatable quantities, that is, inaccuracies are minor. The application of standard deviation is generally used as a precision error.
Accuracy refers to the part of an apparatus that provides measures whose average is nearer to the accurate value. It is the reproducibility of an apparatus.
Answer:
Make sure all tested rats are the same age.
Offer the same type of food to the rats in each trial.
Explanation:
<em>In order to be able to isolate the effects of one particular variable during a research, all the subjects in each trial must be subjected to the same conditions except the variable whose effects is being isolated.</em>
Hence, Kate must offer the same type of food to the rats in each trial as well as make sure that all tested rats are the same age.
The largest biome according to land in the world is Taiga,
also known as boreal. It covers almost 30% of the world’s forest and by country
it covers the land of North America, Canada and Russia. There are many
categories of biomes according to their specific quality or reason like dessert,
rainfall etc.
Acid rain is an example of chemical weathering
