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
Transcription in scientific genetics is used to describe the copying of the genetic sequence of DNA on messenger-RNA during expression of genes. On the other hand, translation is used to describe the use of the MRA to convert the gene sequence to amino acid sequences with the help of ribosomes.
Answer:
Limit their fast food intake.
Explanation:
Fast food places have a lot of salt in their food because adding salt, which is a preservative, allows them to store the food supplies longer and save money.
The statement that correctly pairs biotic factors with an effect on the biosphere is that biotic factors would decrease the oxygen in the soil.
<h3>What are biotic factors?</h3>
Biotic factors of an ecosystem refers to the living components of that ecosystem. Biotic factors include the following:
Biotic factors make use of oxygen in the atmosphere to perform the process of respiration, hence, their presence will cause a decrease in the oxygen content.
Therefore, the statement that correctly pairs biotic factors with an effect on the biosphere is that biotic factors would decrease the oxygen in the soil.

The plant on the right must have been the one given a saltwater mixture while the one on the left must have been given pure water.
<h3>Osmosis</h3>
Looking at the attached image closely, one would see that the plant on the right has withered leaves while the leaves of the plant on the left seem to be flourishing.
The plant on the right must have been the one fed with water mixed with salt and here is the reason. Adding water mixed with salt to the soil on which the plant grows will decrease the water potential of the soil relative to the water potential of the plant's root. Thus, water will move from the plant into the soil through the root by osmosis. This will cause the various cells of the plant to become flaccid, and hence, the withered leaves.
On the contrary, the plant on the left must have been fed with pure water. Feeding the soil with pure water will increase the water potential of the soil relative to the water potential of the plant's root. Thus, water will move from the soil into the plant through the root by osmosis. This will cause the various cells of the plant to become turgid, and hence, the flourishing leaves.
