Answer:
The lids of the Petri dishes were inadvertently left on while being sterilized
Explanation:
- The process of eliminating any microbe from a particular object to achieve a sterile aseptic environment is termed as sterilization.
- Sterilization mainly aims to either remove, kill or make any microbe inactive by using various means such as irradiation, heat, pressure, etc.
- In the given question radiation is used to sterilize the Petri dishes and thus, if sterilization is successful there should not be any contamination.
- However, since there is contamination present amongst the bacterial colonies growing on agar plated in the Petri dishes this shows that the sterilization has not been done successfully and a possible reason for this could be that while sterilizing the<em> lids of the Petri dishes were kept on. </em>
Answer:
No, I don't reckon that water is alive. I don't think that it is "dead" either. It simply just... exists. However, it DOES hold life within it. But the water itself is not alive, because for something to be considered "alive", it must meet the requirements of responding to stimuli, reproducing and growing, and must be dependent on its environment. Water itself cannot be dependent on an environment, because it IS an environment.
This is just my opinion though :)
Answer:
The correct answer is - 3 hours 15 minutes.
Explanation:
Given:
Speed = 768 km/h
distance = 2496
Solution:
Converting speed in km/minutes:
768/60 = 12.8
Now by the formula,
Time = distance/speed
time = 2496/12.8
=195 minutes
converting in hour = 195/60
= 3 hour 15 minutes.
The mother of the bunnies is white while their father is black. The independent assortment of the genes during the formation of gametes ensures that each parent contributes same amount of the genetic information to the offspring. The more number of black bunnies than white is because of the dominance of the gene coding for the black fur trait over the white fur trait.
Hence, the correct answer is 'Option F'.
