I believe the answer is photon
Answer:
See below for answer
Explanation:
<u>A. 200 mOsM NaCl</u>
This solution is hypotonic to the red blood cell (RBC) with penetrating solute. The RBCs will swell up and burst because the water will move into the cells.
<u>B. 400 mOsM urea</u>
This solution is hypertonic to the RBCs with non-penetrating solutes. Water will leave the cells via osmosis and the cells will shrink and appear shriveled.
<u>C. 100 mOsM urea plus 200 mOsM NaCl</u>
This time both penetrating and non-penetrating solute is present. The solution is isotonic to the RBCs and although there will be movement of water between the cells and the solution, there will be no overall change in the concentration of water for each and no change in appearance of the cells.
<u>D. 300 mOsM urea</u>
The RBCs will not lyse nor shrivel as again the solution is isotonic to the RBCs.
Answer:
Unlike inbreeding, hybridization is more likely to cause genetic abnormalities.
It refers to the idea the prehistoric oceans combined with lightning formed the building blocks of life.
Explanation:
The primordial soup refers to the idea that prehistoric oceans combined with lightning to form the building blocks of life.
The soup can be regarded as the soup of life through which the first nuclei acids were synthesized.
- It was a hypothesized set of conditions available when the earth was initially formed about 4.5 billion years ago.
- The miller-urey experiment was set up in 1930's to demonstrated this soup of life.

Answer:
-1.9mL/min
Explanation:
The rate of O₂ production can be calculated by the formula
= ( Final volume - initial volume)/time(min).
From the graph provided and attached below, the rate of O₂ production or rate of photosynthesis at light intensity of 8 is about 3.75 mL/min.
The rate of O₂ production is taken as the rate of photosynthesis. It is expected to progressively increase from light intensity 0 as light intensity increases. However, at very high light intensity, the rate slows down as water becomes limiting and the stomata closes in order to conserve water.

Experiment 2: Respiration in the Dark
Calculate the volume change for respiration in the dark. As you already saw from earlier questions,
oxygen production is fairly constant. You will not need to calculate the individual volume changes.
Just subtract the original volume at 00:00:00 from the final reading at 00:02:00. Record your answer
for use in a later question.
