because the sperm fertilizes the egg and creates the zygote thing
The body doesnt make iodine so its a essential part of your diet
Explanation:
In amoeba respiration takes place through its cell membrane also called the plasma membrane. Amoeba gets oxygen gas dissolved in surrounding water through its plasma membrane by the process of diffusion. The oxygen gas diffused inside the body is used up by the amoeba. In the body, the oxygen gas absorbed is used to break down the complex food material into simple molecules. During these metabolic reactions in the body of amoeba, the oxygen gas is converted into carbon dioxide gas. The carbon dioxide gas is also liberated in the surrounding water through the same process of diffusion.
Since amoeba needs oxygen for respiration, the type of respiration is aerobic respiration.
A. i think its this because they get their energy from gravity. its originally potential energy as a cloud but as the water droplets condense and collect into rain drops they get heavy and that potential energy is turned into kinetic energy. this isnt up there so A.
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.
