B, cold with a high salt content, I believe. Since density is mass divided by volume, adding salt would increase mass. Temperature is related to kinetic energy and the distance between molecules/atoms of a substance. The hotter the substance, the more distance there is between particles. Generally cold water is more dense. Hope i helped :D
True
Science is often tainted by biases in the science community.
Viewing a cell's mitochondria
Seeing animal tissue that is visible to the naked eye
Studying the structures of a live paramecium
I think it might be the first one
Answer: Viewing a cell's mitochondria.
A transmission electron microscopy is a microscopic technique in which a beam of electron is transmitted through a specimen to form an image. It magnifies the structure of the specimen with high resolution as compared to light microscopes. It can be used to examine the internal structure of the cell. Transmission electron microscopy can be used to study the organelles in the cells. Hence, it can be used to view a cell's mitochondria.
Answer:
Viewing a cell's mitochondria
Explanation:
Can't be the live specimen one because electron microscopes can't view living things.
It's best for looking at things in detail!
