Read the assigned article on MyOn called: Vacuuming Up Animal DNA! The questions in this assessment are based on this article.

Question

Why is it important that the scientists’ vacuum device can filter skin cells and hair from the air?

(1 point)
Responses

They can use those pieces to reconstruct the organism.
They can use those pieces to reconstruct the organism.

It isn’t important. Those pieces are not very useful.
It isn’t important. Those pieces are not very useful.

Those pieces hold DNA, which the scientists can use to identify the animals.
Those pieces hold DNA, which the scientists can use to identify the animals.

Answer 1

The correct response is:

Those pieces hold DNA, which the scientists can use to identify the animals.

This is important because analyzing the DNA from skin cells and hair can help scientists identify the species and gather information about the animals in that environment.

Answer 2

Why did Elizabeth Clare and her team use a group of naked mole rats that had been in one room for many generations in their study?(1 point)
Responses

The DNA would have built up in the air during the time they had been there.
The DNA would have built up in the air during the time they had been there.

The DNA would have spread out and been more difficult to obtain.
The DNA would have spread out and been more difficult to obtain.

Naked mole rats are special because they do not have DNA.

Answer 3

The correct response is:

The DNA would have built up in the air during the time they had been there.

Using the same group of naked mole rats in one room for many generations allows the scientists to collect a concentrated sample of DNA in the air.

Answer 4

When the Denmark researchers tested their device in zoos, what type of animal DNA were they surprised to find floating around in the air?(1 point)
Responses

Guppy DNA
Guppy DNA

Bird DNA
Bird DNA

Wolf DNA
Wolf DNA

Human DNA

Answer 5

The correct response is:

Bird DNA.

The researchers were surprised to find bird DNA floating around in the air when they tested their device in zoos.

Answer 6

True or False. The research teams from Denmark and London always knew that they were all working on similar studies.(1 point)
Responses

True, they were working together.
True, they were working together.

False, they did not know initially, but now they are working together.

Answer 7

The correct response is:

False, they did not know initially, but now they are working together.

Initially, the research teams were unaware of each other's work, but they later realized their studies were similar and began collaborating.

By the ninth century, the Response area empire had emerged in eastern Indochina. It developed around agriculture and used Response area to store water. To the south, the Srivijaya empire emerged in Response area . It relied on farming and trade.

Answer 9

Here are the appropriate responses for the sentences:

By the ninth century, the Khmer empire had emerged in eastern Indochina. It developed around agriculture and used irrigation to store water. To the south, the Srivijaya empire emerged in Sumatra. It relied on farming and trade.

So, the filled sentences would be:

By the ninth century, the Khmer empire had emerged in eastern Indochina. It developed around agriculture and used irrigation to store water. To the south, the Srivijaya empire emerged in Sumatra. It relied on farming and trade.

Answer 10

select different ones for the last two

Answer 11

Sure! Here are alternative selections for the last two:

By the ninth century, the Khmer empire had emerged in eastern Indochina. It developed around agriculture and used canals to store water. To the south, the Srivijaya empire emerged in Java. It relied on farming and trade.

So the filled sentences would be:

By the ninth century, the Khmer empire had emerged in eastern Indochina. It developed around agriculture and used canals to store water. To the south, the Srivijaya empire emerged in Java. It relied on farming and trade.
