Answer:

217.3ml

Explanation:

In order to answer this question, we apply Charles' law, which states that at a constant pressure, the volume of a fixed mass of gas (V) is directly proportional to the temperature (T).

That is, V = KT

K = V/T

Hence, V1/T1 = V2/T2

Where; V1 = initial volume

V2 = final volume

T1 = initial temperature

T2 = final temperature

The unit of temperature must be in Kelvin (K), which is the unit for absolute temperature.

To convert Celsius (°C) to Kelvin (K), we use; K = C + 273

Hence, T1 = 273 + 20 = 293K

T2 = 273 + 10 = 283K

V1 = 225ml

V2 = ?

Using the formula; V1/T1 = V2/T2

225/293 = V2/283

We cross multipy;

293 × V2 = 283 × 225

293V2 = 63675

We divide both sides by 293

V2 = 63675/293

V2 = 217.32

Hence, the new volume (V2) is 217.3ml

How do the chromosomes in most cells of an organism, such as the leaf cells of a plant, compare to the chromosomes in its reprod
Lunna [17]

Answer:

Reproductive cells have half the amount of chromosomes than body cells

Explanation:

I think that you are talking about body cells when you say "most cells in an organism." If that is the case, then the reproductive cells, sperm and egg cells, have half the amount of chromosome than body cells.

For example: Human body cells have 46 chromosomes. Human reproductive cells has 23 chromosomes.

In sexual reproduction, each parent gives 1/2 of a full set of chromosomes to create the full set needed for an organism.
