Answer:
the time that cell spend in prophase is 30 minutes
Explanation:
The computation is shown below:
= Number of cell ÷ sample
= 25 ÷ 100
= 1 ÷ 4
Now it takes two hours
So,
= 1 ÷ 4 × 2 hours
= 0.5
This 0.5 represent the 30 minutes
Hence, the time that cell spend in prophase is 30 minutes

Answer:
a discovery by a human being
Explanation:
The correct answer would be a discovery by human being.
Penicillin existed in nature and was only discovered, albeit accidentally, by Alexander Fleming.
It is different from<u> technological innovation because the latter requires the synthesis of products that are not in existence already or improvement on a product that has been created before</u>.
Discovery is also different from advancement in technology. <u>The latter refers to the process of inventing, innovating, and spreading technological processes in society.</u>
Discoveries are usually natural and are not in any way an invention. However, advancement in technology can aid discoveries.
Answer:
The correct answer would be carrying a box.
Work is done only when force is able to cause a displacement.
It can be calculated by multiplying the force applied (F) and the displacement (S) caused.
W = FxS
If the force applied and displacement are in the same direction then the value of work done is taken as positive.
In contrast, when the force and displacement are in opposite directions the value of the work done is taken as negative.
Lastly, when there is no displacement then the work done is zero.
In carrying the box, there is no displacement occur due to which work done is zero.
