It was believed that the magnetic field to be generated deep down in the Earth's core. But the truth is the flow of liquid iron generates electric currents, which produces magnetic fields.
But the truth is no one really knows for certain so the only thing we know is that the spin of the earth is the cause of its magnetic field
Hope this helped :)
Have a great day
I believe it would be an observation
Observation in scientific process refers to gathering facts and information. In this particular context, we could see that the microbiologist is simply stating what he/she saw on the mold on the agar plate. The microbiologist simply writing down all the facts without making any explanation or assumption.
Answer:
stronger and longer organ are able to mate more with females, whereas the shorter one didn't stand a chance.
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.
It is - Many scientific observations, related to biogeography and comparative anatomy were made, documented, and shared.
