Answer:
Their nephron loop is closely wrapped with vasa recta.
Explanation:
Cortical nephrons are located in the cortex.
They form 85% of all the nephrons in the kidney. They are located mostly within superficial cortex of kidney. The loop of henle of a cortical nephron is relatively short and hence not closely wrapped with vasa recta. Efferent arteriole delivers blood to a network of peritubular capillaries.
Answer:
"...for many of our white brothers, as evidenced by their presence here today, have come to realize that their destiny is tied up with our destiny."
(A)
Remember that a controlled variable is a variable that stays the same thoughout the experiment.
it wouldn't be a. because two different wires were used
the final length of the wax would be your dependent variable, so it wouldn't be c.
the thermal conductivity is the independent variable so it isn't d.
the original length of the wax was the same for both.
So B is your answer.
The correct option is A.
Living organisms depend on their environment to survive, when there are changes in the environment which are not favorable to the living organisms, it will eventually leads to the wiping out of the living organisms. As time goes on and the environment recover, the living organisms that will be found in the new environment are those who will be able to survive in it.
Some of these can easily be eliminated by knowing that both nitrogen 14 and nitrogen 15 are isotopes ( same element, with the same amount of protons, but with different numbers of neutrons) of nitrogen. So if the only difference between nitrogen 14, 15 , and regular nitrogen is the amount of neutrons...how many protons and electrons should both nitrogen 14 and 15 have? After thinking, you should be able to eliminate A, B,and C.
