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
The sinking of rock layers is subsidence
Explanation:
Subsidence is the motion of a surface as it shifts downwards corresponding to a datum such as a sea level. The reverse of subsidence is uplift, which occurs in an increase in elevation.
Cross contamination means the transfer of pathogens from surface to another
Answer:
The correct answer will be option B.
Explanation:
Mitochondria are the double-membrane organelles present in eukaryotic cells which helps in generation of the energy currency that is ATP of a cell.
Mitochondria provide a site for the generation of these ATP molecules, the reason they are known as the kitchen of the cell. Their number in a cell depends on the function of the cell as if a cell is involved in function which need more ATP will have more mitochondria and if not will have few mitochondria.
Since a cardiac muscle cell needs more energy to pump blood from one chamber to another and to body, therefore, cells will have more mitochondria and thus, option B is the correct answer.
Answer:
The correct answer is - volcano leads to rock or land formation and the change of mountains and earthquakes causes a landslide and other changes.
Explanation:
A volcanic eruption changes the surface of the earth by the eruption of molten and magma that leads to new rock formations or mountains. It builds up the land or rocks around a volcano when lava flows out and hardens on the surface.
The surface of the Earth change by cracking and shifting when an earthquake hits and cause landslides as well as the point where the crust moves.
