Choose any electromagnetic wave we have discussed and write ONE PARAGRAPH telling me about the uses/benefits of that electromagn
uysha [10]

Answer:

A gamma-ray, or gamma radiation, is a penetrating form of electromagnetic radiation arising from the radioactive decay of atomic nuclei. It consists of the shortest wavelength electromagnetic waves and so imparts the highest photon energy. Paul Villard, a French chemist, and physicist discovered gamma radiation in 1900 while studying radiation emitted by radium. In 1903, Ernest Rutherford named this radiation gamma rays based on their relatively strong penetration of matter; in 1900 he had already named two less penetrating types of decay radiation alpha rays and beta rays in ascending order of penetrating power.

Explanation: hope this helps :)

​rich sources of polyunsaturated fatty acids are found in ____. ​lamb ​sunflower oil ​milk ​egg yolk ​fish eggs
mihalych1998 [28]
Fatty acids are mostly composed of chains of carbon and hydrogen. Fatty acids without double bonds are "saturated" with hydrogen. When a fatty acid has one double bond, hydrogen is released therefore the fatty acid is "monounsaturated". When a fatty acid has two or more double bonds, then the fatty acid is "polyunsaturated". Unsaturated fatty acids are usually takes in the form of oils as they are liquid in room temperature (in contrast to saturated fatty acids which are solid in room temperature). Unsaturated fatty acids are usually found in plant based fats such as oils. Therefore the answer to this question is sunflower oil.

Due to a genetic modification, a mouse has no horizontal cells in its retinas. What impact will this have on the mouse’s vision?
Karolina [17]

Due to a genetic modification, a mouse has no horizontal cells in its retinas and it does not expresses the connexin26.

What is  horizontal cells?

The horizontal cells has receptive field with the neurobiotin and controlled by the electrical coupling.

Horizontal cells are the laterally interconnecting neurons having cell our bodies withinside the internal nuclear layer of the retina of vertebrate eyes. They assist combine and alter the enter from a couple of photoreceptor cells.
