Answer:
to help and determine the exact age of the rocks
Explanation:
The study of rocks strata is known as stratigraphy. It is useful and helps the scientist and the researcher to study the earth's crust and its past.
Scientist could age the rock using two methods. They are :
Relative ages
Absolute ages
Early scientist could determine the exact age of the rock of the earth's crust. They use to find the relative ages of the layers of the rocks and then determine how one rock layer is older or younger than the other. But with advancement and development of carbon dating, scientist could tell the exact age of the rocks found on the earth's crust.
The Scientists uses the relative as well as the absolute dating technique to date the rock layers. They organize the rock layers based on their age and scale from the oldest to the youngest on a geologic time scale. So an exact date of the rocks can be determine by using the two methods of relative age and the absolute age.

Explanation:
Answer: Homocystine
Explanation:
Homo cysteine is the amino acid which is found in the cheddar cheese, eggs, chicken and beef it is also been linked to cardiovascular disease.
It helps in promoting the blood clotting, damage the inner linking of blood vessels and promote the thickening and loss of flexibility in the blood vessels.
So, the amino acid Homocystine is found in beef, chicken and has been linked with the cardiovascular diseases and Alzheimer disease.
Human cells do not have cell walls is the statement which best describes antimicrobial drugs that affect cell wall synthesis
Explanation:
Human cell is very different from the bacteria and foreign materials which enters into the body. There are many bacteria and virus which tends to cause disease in the human body.
There are many medicines such as antibacterial, antimicrobial drugs which are helpful for dealing with these bacteria and viruses. Human cells do not have cell wall.
Some of the bacteria and virus too have cell walls. The antimicrobial and antibacterial which we take, takes action on the cell walls and try to destroy it.
