Considering the definition of density, you obtain that:

Part A: the density of gold is 19.3 g/cm³.
Part B: the density of iron is 7.8 g/cm³.

<h3>Definition of density</h3>

Density is defined as the property that allows to measure the amount of mass in a certain volume of a substance.

The expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:

density= mass÷ volume

It can be deduced that density is inversely proportional to volume: the smaller the volume occupied by a given mass, the higher the density.

<h3>Density in this case</h3>

In this case, you know that:

A sample of gold has mass of 38.6 grams and a volume of 2 cm³.
A sample of iron has a mass of 46.8 grams and a volume of 6 cm³.

Replacing in the definition of density:

Gold: density= 38.6 g÷ 2 cm³
Iron: density= 46.8 g÷ 6 cm³

Solving:

<u><em>Gold: density= 19.3 g/cm³</em></u>
<u><em>Iron: density= 7.8 g/cm³</em></u>

In summary, the density of gold is 19.3 g/cm³ and the density of iron is 7.8 g/cm³.

If the environment experiences a drought which adaption would most likely help an organism survive?

Ivahew [28]

If a drought were to occur, an organism who has an adaptation for moisture retainment would be the most likely to survive. This is because they will be able to survive the lack of water during the drought and still stay hydrated.

A good situation similar to this would be succulents in the desert. Each of them have the ability to retain high amounts of water when there is precipitation, which allows them to perform all of their needed functions in order to survive.

I hope I helped!

Which revision changes the dependent clause into an independent clause?

Lunna [17]

The given question is incomplete. However, the complete question is given below:

Read the dependent clause.

after the conversation with her publisher, when she decided to write an autobiography

Which revision changes the dependent clause into an independent clause?

After the conversation with her publisher, because she decided to write an autobiography.

Since the conversation with her publisher, when she decided to write an autobiography.

After having the conversation with her publisher, when she decided to write an autobiography.

After the conversation with her publisher, she decided to write an autobiography.

Answer:

The correct answer is - After the conversation with her publisher, she decided to write an autobiography.

Explanation:

The revision that alters the dependent clause (incomplete thought) into an independent clause (a complete thought) is the following one:

"After the conversation with her publisher, she decided to write an autobiography."

The reason behind this is that an independent clause is a clause that expresses a complete thought and no need for other clauses to be associated.

The other options (a and b) are grammatically incorrect when presented as independent clauses, whereas D is completely okay.

Why was the discovery of organisms, such as archaeopteryx, that have a mix of traits usually associated with two different group

Jlenok [28]

The answer would be transitional forms like Archaeopteryx make available DNA confirmation that demonstrates how organisms are related. Transitional fossils establish the middle forms that happened over the evolutionary trail taken by a single genus. A case in point of a transitional fossil is archaeopteryx, which relates the evolution of dinosaurs (from jaws and claws) to birds (feathers).
