Answer:

My guess would be H₂O/ water, since osmosis is a form of passive transport and I can't see the model the question references. Gases like O₂/ oxygen, CO₂/ carbon dioxide, and simple sugars like glucose can also pass through a cell membrane with passive transport though.

Why did Bill Nye pressurize the giant "cloud bottle"? What purpose did this serve?
zubka84 [21]

Answer:

Water molecule is present in air these airborne water molecule are called water vapor, when the molecules are present in air they don't normally stick together as the space is too much.

Bill Nye took a giant bottle and covered it with a stopper and started pressurizing it with a pump to make the molecules come closer and become compressed also it increase the temperature even slightly and that warmth will cause the liquid stick with the smoke particles to go back to forming as vapor.

After that he removed the lid then the air inside the bottle is spread out and it will eventually cool also the kinetically energy is also reduced and that cooled air sticks with dust particle which now forms cloud.

This experiment shows how the clouds are formed and the science associated with it.

In humans, what gamete determined the sex of an offspring?
kari74 [83]

In humans, the "male gamete determines the sex of an offspring because it may contribute either an X or a Y chromosome"

<u>Answer:</u> Option C

<u>Explanation:</u>

Human sex gets decided by the function of SRY gene which possessed by with or without of Y chromosome. The hormone of anti-mullerian and testosterone produced from cells when activating the SRY gene. It generally confirms the development of single-male reproductive systems.

The scenario in humans, the sex ration gets affected by the male parent's hormone level. Also, in XY sex evaluation system, the sperm of male takes part in X or Y chromosome whereas the ovum from female contributes to X chromosome. This greatly results in offspring - either male (XX) or female (XY).
