Explanation:

Putting the plant in dark for 48 hours would stop the process of photosynthesis as light is required for it. Photosynthesis produces organic sugars which are stored in form of starch in plants. The absence of photosynthesis would lead to consumption of all stored starch making the leaf starchless.

Scientist are studying an 500g. Sample of a radioactive element. Which has an annual decay rate of 11%. How many grams of the sa

gtnhenbr [62]

Nothing

Explanation:

Mass of the sample = 500g

Decay rate per anum = 11%

Unknown:

Mass of sample remaining after 10yrs = ?

Solution:

This is a simple percentages problem;

The radioactive sample loses $\frac{11}{100 }$ x 500g of sample per year;

this is a loss of 55g per year;

In 10years time, the sample would have lost 10 x 55g = 550g of element.

Since our sample is not up to 550g, then no amount of sample will remain after 10yrs.
