General Remark
The amount of energy transferred from the sun to the wood and steel is determined by m*c*deltaT. [So far, you really only have 2 choices for heat energy transfer. One is the one you are using m*c*deltaT and the other one is Mass * heat. This latter is for phase changes].
Solution
What causes the temperature to be higher in one part of the sample than on the other part? If they both receive the same amount of heat (as in getting their energy from the sun) then why does one deltaT exceed the other? Look around at the parts of the formula. That's very important in science. The mass (m) is not going to affect the different temperatures. The mass is the same in both cases.
It won't be deltaT either. DeltaT has already done it's job. It's recorded that there is a temperature difference. Steel has a larger deltaT than the wood.
What's left?
It must be the c. What are the units on c? If you check it out it is joules / (oC * grams) or something that means grams and deltaT. So c must be lower than steel than for wood. Why? Because it takes less energy to heat up the steel. Small c means large deltaT if the temperature is greater in the iron.
Answers
<em><u>Blank One </u></em>absorbed more energy from. c is small.
<em><u>Blank Two</u></em> Less than.
This is an extremely important question to get a handle on. More and Less are very important key words in Science.

The movements of the substance across the dialysis membrane are as following: water: Moves in both directions.
Glucose: Moves into the blood.
Urea: Moves out of the blood.
Na, K, and Ca ions: Moves in both directions.
<h3>What is dialysis?</h3>
Dialysis is a process of filtration and purification of blood by a machine. This machine helped those people whose kidney stop working and doesn't purify the blood.
Thus, the correct options are: water: Moves in both directions.
Glucose: Moves into the blood.
Urea: Moves out of the blood.
Na, K, and Ca ions: Moves in both directions.
