Question 5

In a fatty acid molecule, the carbon found at the beginning near the carboxyl terminal is known as the omega carbon.

1 / 1 point

It is known as the alpha. The carbon at the end is known as the omega.

Question 6

Which of the following are health issues that a diet with omega-3 fatty acids can help?

1 / 1 point
==========================================

Question 7

Humans are able to synthesize important fatty acids such as EPA and DHA.

1 / 1 point

We cannot, we need to supplement our diet to include these fatty acids.

==========================================

Question 8

Wild marine fish are primary producers of omega-3 fatty acids.

1 / 1 point

Marine algae are and fish accumulate the fatty acids through the food web.

==========================================

Question 9

Currently, the majority of commercially produced omega-3 fatty acid from micro-algae is done heterotrophically.

Question 10

In the UCSD algae genetic modification field trial, the genetically-modified strain accumulated fatty acids as much as it did in the lab.

1 / 1 point

While it did still accumulate more fatty acids than the wild type, it was not as dramatic as in lab settings.

==========================================

Question 11

In the UCSD algae genetic modification field trial, the genetically modified algae did not disperse beyond the cultivation pond.

1 / 1 point

It was found in all of the target ponds as far as 50 meters to the north and east.

==========================================
