1 answer:

7 0

Answer:

Explanation:Bioaccumulation occurs when toxins build up - or accumulate - in a food chain. The animals at the top of the food chain are affected most severely. This is what happens: Small amounts of toxic substances - often pesticides or pollution from human activity - are absorbed by plants.while biomagnification is the process by which toxins are passed from one trophic level to the next (and thereby increase in concentration) within a food web. ... dissolve into the fatty tissues of living organisms.

The final pattern you wish to obtain expresses the UASG-GFP construct only in cell C2. How will you drive UASG-GFP expression sp

Nat2105 [25]

Answer:

Explanation:

Here, cell C-2 needs to express GFP and therefore, GAL4 should be functional in cell C-2. This can be achieved by expressing GAL4 in Regulatory DNA construct 3, and expressing GAL80, an inhibitor of GAL4 in Regulatory constructs 1 and 2. This arrangement expresses GAL4 in columns A and C, and inhibits GAL4 due to GAL80 expression in Columns A and B; and in rows 1 and 3.

Therefore, the only cell that expresses GAL4 is cell C-2.

The arrangement is:

1. Construct 1 should express GAL80

2. Construct 2 should express GAL80

3. Construct 3 should express GAL4

4. Construct 4 should not be used
