Electron microscopes use
Pavel [41]

Electron microscopes use _beam of electrons___ in order to allow for higher magnification and more detail when viewing specimens.

Explanation:

A beam of electrons has a shorter wavelength than normal light used in light microscopes, by approximately a factor of X 100000. Therefore, electrons microscope have the inherent attribute of having a very high resolution. They have been used to discover very small organelles in cells such as the ribosomes and mitochondria that cannot be clearly viewed even with the highest resolution in light microscopes.

A gene on a chromosome lies close to another gene controlling a different trait. This indicates that the genes are _. The first
umka2103 [35]

My guess:

I do not know the options to the blanks, but I'd say that the answer to the first one is "strongly linked". Think of a chromosome as a phylogenic chart → 2 species that are beside each other are strongly linked, if compared to 2 species 3 spots apart form each other. So, 2 genes that are close to each other are strongly linked.

I do not know the options to the blanks, but I'd say the answer to the second one is epistasis → which is the interaction between two different genes (different means they're not linked alleles).

Hope it helped,
