7 0

SEM and TEM are electron microscopes whereas the SEM uses reflected electrons and TEM uses transmitted electrons to form an image

Explanation:

SEM is the scanning electron microscopes and TEM is the Transmission electron microscope

SEM works by detecting the scattered electrons to create an image of the sample whereas the TEM detects the transmitted electrons to create the image of the sample

SEM will only be analysing the surface of the sample whereas TEM collects data vertically also

TEM sample needs to cut thinner than SEM and TEM will give high-resolution images than SEM

Which emergency condition requires the immediate use of cardiopulmonary resuscitation (cpr)? quizlety

Emergency condition like Myocardial Infarction requires the immediate use of cardiopulmonary resuscitation (cpr).

<h3>What is Myocardial Infarction?</h3>

Myocardial infarction, another name for a heart attack, is an extremely serious condition caused by inadequate blood flow to your heart muscle. Although there are several potential causes, the most frequent one is a blockage in one or more of the arteries leading to your heart. Without blood supply, the damaged heart muscle will start to degenerate. If blood flow isn't quickly restored after a heart attack, there could be permanent cardiac damage and even death.

A heart attack is an emergency that puts your life in danger. If you think you or someone you're with is having a heart attack, dial 911 immediately (or your local emergency services phone number).

Explain how using renewable and recyclable materials can benefit the environment.

Ierofanga [76]

Instead of burning coal to power our country we could use solar panels. As long as we have the sun we will have "free" energy.

Instead of continuing to mine for metals, we could recycle metals and then less greenhouse gases would be released into Earth's atmosphere.
