3 0

Ethical issues that may arise include the not using antibiotics in the correct manner, such as a patient note taken the correct dosages or giving some to family members for things such as a cold. This worst bit is that these actually predispose patients to antibiotic resistant bacteria like Methicilin Resistant Staphylococcus Bacteria which can lead to amputation, severe injury and illness, coma, and death.

Answer:

Light waves can travel with and without mediums.

Explanation:

Light waves are a type of electromagnetic wave. Some of the characteristics (properties) of light waves include;

I. The wavelengths of light range from 400 nm to 700 nm.

II. Light waves are transverse waves.

III. The speed of light is 3 x 10^8 m/s.

<em>Therefore, from the aforementioned characteristics it can be inferred that light waves can travel with and without mediums.</em>

This ultimately implies that, light wave is an electromagnetic wave that do not require a medium of propagation for it to travel through a vacuum of space where no particles exist.

Explain two ways in which scientists use fossils to determine environmental change

drek231 [11]

Hello. Happy to help.

1) Coast Lines: The location of marine fossils can help determine where and when ancient coast lines were in the past.2) Climates: Fossils can be used to determine the past climates. (Was an area cooler or wetter than the present.)

The presence of marine or land fossils indicates whether the land at one time was at the bottom of the ocean or not.

Also, you could mention radioactive dating and relative dating. I am sure that is mentioned in your curriculum.

Hope that helps.
