Answer:
D. Lipids
Explanation:
Lipids include any of a class of organic compounds that are fatty acids or their derivatives and are insoluble in water but soluble in organic solvents. They include many natural oils, waxes, and steroids.
Answer:
Dissolve 47.025 grams of sucrose in enough water to produce 250 ml of solution.
Explanation:
You need to prepare 250. mL of a 0.550 M aqueous solution of sucrose, C12H22O11 (aq),
which is used frequently in biological experiments.
Based on your answer above, what is the value of x?
Solution:
A 0.550 M aqueous solution contains 0.550 mole of sucrose per liter of solution.
250 ml = 0.250 liter
Thus a 0.250 liter of a 0.550 M aqueous solution of sucrose contains 0.250 * 0.550 = 0.1375 mole of sucrose
Recall:
Mass = number of moles * mass of 1 mole
mass of 1 mole of C12H22O11
= 12(12) + 1(22) + 16(11)
= 144 + 22 + 176
= 342 grams
Mass = 0.1375 * 342 = 47.025 grams of sucrose.
Dissolve 47.025 grams of sucrose in enough water to produce 250 ml of solution.
Answer;
Terminal capillaries lacks the three layers.
Explanation;
-All arteries and veins contain three layers, namely; the tunica intima, tunica media and the tunica adventitia. However, Terminal capillaries lacks the three layers, because they are only one cell layer thick, they instead have only tunica intima.
-Tunica intima is the innermost layer of endothelium and associated connective tissue. The middle layer is the tunica media and it is made of smooth muscle cells. It extends from the internal elastic lamina to the external elastic lamina and it varies the most of the three tunics and is diagnostic for classifying vessels.
-The last layer is the tunica adventitia with the outermost collagen rich connective tissue layer that blends with the loose connective tissue of surrounding organs helping to attach the vessels to surrounding tissue.
