Answer:
is primarily responsible for a movement
Explanation:
Working muscles are called agonists or prime movers because to complete a movement they produce major force. These muscles are primarily responsible for the occurrence of a movement. By contracting they make a range of motion for example during the up phase of push up the triceps brachii contracts which produce a shortening contraction.
The muscles that oppose the action of agonists are called antagonists. So antagonists are responsible for the returning of arm or leg in its original position. So the correct answer is- is primarily responsible for a movement.
Complete question:
A student is working on a lab where they are trying to identify an unknown substance. The student decides to smell the solution by taking a big breath over the test tube. They immediately start to cough and their lungs are burning.
Answer and Explanation:
Many chemicals might be recognized by their smell. Some of them might be inoffensive, some others might cause slight damage and some others might be very harmful to the person that inhales them.
In the exposed example, the solution probably damaged the respiratory tract, causing inflammation and irritation.
There are some issues to take into account to avoid an accident by inhaling a chemical:
<u>Precaution</u>:
- Study the security rules of the laboratory
- Always read the label of the substance
- Ask the teacher or the person in charge, about the correct procedure
- Proceed in the correct way, by driving the smelly vapors with your hand toward your nose. Never breathe directly over the test tube.
In case of accidents by inhaling you should:
<u>Response:</u>
- Take the affected person out of the laboratory
- Look for an airy place where the affected person might breath
- Call an emergency service
- Explain exactly what the affected person did and the chemicals that the person inhaled.
