Why should you have an Emergency Action Plan? Select all that apply. a. Seconds can mean the difference between life and death f
Maurinko [17]

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.

Do you think humans will be able to genetically engineer future humans in your life time?
Vlad1618 [11]

✯Hello✯

↪  In our life time, I dont think so

↪  They will be making some robots but I think before any of this happens they will have to find a way to modify genes

↪  By modifying genes this could change people's hair and eye colour build etc

↪  This hasnt had any progress, but is sure to come in the future but I dont think unless there is a scientific revolution that humans will be engineered this way in our life span
