Question

Biochemical engineers have designed a lamp that uses algae to create light. These algae are able to glow in the dark. How could this example of biotechnology help the environmental quality of the planet?

As the organisms inside photosynthesize, they will remove carbon dioxide from the air.
Bioluminescence makes heat as a byproduct that can harvest to warm houses.
It will increase the amount of light available to underdeveloped countries.
The green coloration can be used as a dye to help make clothing for children.

Answer 1

@Allison

Answer 2

I like C. What do you think?

Answer 3

@JustSaiyan answer check.

Answer 4

I literally have no clue any answer is good enough for me.

Answer 9

Good point.

Answer 10

But, Nick.

Isn't algae only in water? How can it help with the air if it's underwater?

Answer 11

All plant life uses photosynthesis to absorb CO2 and Release Oxygen, which is necessary for OUR survival.

Answer 12

So A?

Answer 13

Yep, always trust Nick.

Answer 14

Well it is safe to say children won't be wearing clothes made of algae.

Answer 15

Answer 18

Ooo uhm.

Answer 19

I'm gonna go and cross C out? >.<

Answer 26

As human populations have changed over the years, people have altered the course of rivers and other waterways to better suit their needs. One approach has been through the damming of certain rivers. Over time, many people question whether this effort has been beneficial. What are the negative impacts of damming a river that are being assessed?

Dams allow more water to flow into nearby reservoirs, increasing the chances of disease transmission.
Dams cause increases in salmon populations because more water is available for them to live in.
Dams reduce salmon stocks, which reduces revenue and overall whale populations.
Dams keep many species from migrating into the area, which reduces biodiversity.

Answer 27

I think this one might be D

Answer 28

Yeah.

Answer 29

When animals consume a toxic material and it builds up in their bodies more quickly than it can be metabolized or excreted, it may harm them, as well as humans who consume them. What is this process called?

Biomagnification
Biological half life
Environmental persistence
Environmental stability

Answer 30

C?

Answer 31

Biomagnification

Answer 32

Or A.

Answer 33

Why does using zebrafish as a model organism for genetic testing bring up ethical concerns?

As invertebrates, they have more genes than other animals.
As vertebrates, they are similar to humans.
As an endangered species, they need to be protected.
As fragile organisms, extra care needs to be taken when handling them.

Answer 34

B?

Answer 35

That would be a positive.

Answer 36

C?

Answer 37

Or D?
