grandymaker [24]

Answer:

The correct answer is c) are plant cells.

Explanation:

The cells cannot be animal cells, because they have not wall (this kind of cells has only plasma membrane). In addition, eukaryotic cells have membrane-bound organelles (which are surrounded by a phospholipids membrane, such as endoplasmatic reticulum, Golgi apparatus, lysosomes, etc.), whereas prokaryotic cells lack them. Since plant cells are eukaryotic and bacterial cells are prokaryotic, the cells you are looking are plant cells.

If a sample of air contains 1 g/kg of water vapor and has a relative humidity of 25 percent at -5 degrees Celsius how much water
guapka [62]

Answer:

Option C

Explanation:

As we know that

Relative humidity (RH) is defined as the ratio of amount of water vapor present in a given sample of air to the maximum amount of water that can be  absorbed by the same sample of air to attain saturation  at a particular temperature .

Thus,

RH = \frac{X}{Y} \\

Where X represents the current amount of water vapor present in a given sample of air

and Y represents the maximum amount of water that can be  absorbed by the same sample of air to attain saturation  at a particular temperature

Substituting the given values in above equation we get -

0.25 = \frac{1 g/Kg}{Y} \\Y = \frac{1 g/Kg}{0.25} \\Y = 4 g/Kg

Hence, option C is the correct answer
