Answer:

The correct statements are that the Curiosity rover found sulfur compound in rocks, and detected carbon in organic molecules.

Explanation:

The Curiosity rover detected methane gas in the atmosphere of Mars as well as organic substances from shallow-soil samples from Gale crater. Both the soil compounds and methane gas are organic matter. The organic matter is chemically illustrated as combinations of hydrogen, carbon, and other elements basically witnessed in biology like oxygen and sulfur, that is, usually related to life.

At certain times, the rocks can get produced on their own via the geological procedures. However, discovering organic matter in such large concentration indicates that it potentially exhibit biological origins, either from bacteria or other life forms, which prevailed long ago.

The Curiosity rover found sulfur compounds in rocks and carbon in organic compounds like propane, butene, benzene, toluene and thiophene.

It detected methane, not in soil samples, but in the Martian atmosphere.

It did not discover helium in underground pockets. The hole it can drill is only 5 cm deep.

If you have studied the chemistry of fats can you identify the end arrangement found in fatty acids as well as amino acids? What

White raven [17]

Answers:
1) - COOH
2) carboxyl group

The organic acids contain the carboxyl group: - COOH.

Fats are structures composed by fatty acids. Fatty acids are long aliphatic chains with a carboxyl group at the end.

Aminoacids are chains that contains amine group (NH2) at one end and the carboxyl group at the other end.

Then both aminoacids and fatty acids contain the carboxyl group (-COOH) at one end.

A rod measures 17.2 inches.<br> How many centimeters is<br> this?<br> [ ? ] cm

Rufina [12.5K]

This problem is providing the length in inches of a rod and it is being required to convert it to centimeters. According to the following, the answer will be 43.7 cm:

<h3>Units conversion:</h3><h3 />

In science, we use units conversion to represent measurements in different types of units depending on a specific requirement. To do so, we use conversion factors based on equivalence statements, relating the required unit with the given one.

In this case, the equivalence statement between inches and centimeters is 2.54 cm = 1 in and we can use it to get the answer as shown below:

$17.2in*\frac{2.54cm}{1in} \\\\=43.7 cm$
