Organism X existed for a short period of time. I really like geology so trust me, I am 100% sure about this question.
(Mark me as the brainiest if this answer helps you!)
The answer would be genes.
A. It acknowledges the correct amount of decimal points and could be a reasonable measurement.
B is incorrect because we don’t have measurements down to the hundredth place on the ruler.
C is incorrect because it doesn’t acknowledge the amount of decimal places available, only stating it as a whole number.
D is incorrect for the same reason as C.
I think it’s B
I hope this is helpful
Explanation:
Starting off, the conditions required for a seed to germinate are:
- warm temperatures, so that enzymes can act efficiently.
- water, for chemical reactions to place.
- oxygen, for respiration.
<u>Observations</u>:
Dry cotton wool: Seeds placed here will not germinate. They will not show any changes since not all the the conditions are met. (There's no water)
Wet cotton wool: Seeds placed here will germinate since all the conditions required for germinations to take place are met.
Covered with water: The seeds will gradually start to expand. The oxygen which is dissolved in water does not enter the seed due to excess water thus preventing germination.
