Answer:
Step 1. 1:100
Step 2. 1:1000
Step 3. 1:100,000
Explanation:
At first step, 0.1 ml is diluted in 9.9 ml of saline. Multiple both with 10 you will get 1 ml in 99 ml suggesting total dilution at first step as 1:100.
At second step, 1 ml of 100x dilution will be taken and further dissolved in the 9 ml of B3. Here, the dilution factor is further 10 times therefore the total dilution would be 1:1000.
At third step, 0.01 ml would be taken from 1000x dilution and further diluted in 9.99 ml. Therefore, the dilution factor here is 100 times. Hence the final dilution at this stage would be 1:100,000.
This is the simplest explanation I can give.
Hope it helps.
Answer:
Emergency Action Plan is necessary because- EAPs reduce the likelihood you will be sued if a student is injured. And EAPs let everyone on your staff know and practice what to do in case of an emergency.
Explanation:
Emergency Action Plan is a plan which addresses emergencies in a schools, workplace, or any institution. If any emergency situation like fire, floods occurs then EAP helps to lessen a trouble.
EAP is necessary because it makes the staff members aware about the preventive measures in an emergency situation. Apart from this, god forbid if any student is injured despite having an EAP, then chances are that the person in authority will not be sued mainly because the incident occurred despite having EAP and not without EAP.
The correct answer is C.
In the aquarium, the water plants would provide the O2 molecules necessary for the snail's metabolism and the snail would release the CO2 molecules that are a byproduct of his metabolism into the container. The CO2 would later be used by plants to make sugar in the process of photosynthesis, releasing more O2 and the cycle of two gases would be completed.
