Answer:

The correct answer would be a hydrogen bond.

The two strands of the DNA are held together with the help of hydrogen bonds formed between the nitrogenous bases or base pairs.

The adenine (A) base pairs or makes a hydrogen bond with thymine (T) and guanine (G) base pairs or makes a hydrogen bond with cytosine (C).

2 hydrogen bonds are present between the A and T whereas 3 hydrogen bonds are present between G and C.

A scientist is observing onion cells and human cheek cells under a microscope. Which observation does she most likely make?

The main difference between a plant cell and the animal cell is the presence of cell wall.

In the plant cell, the cell wall is present, but in the animal cell, the cell wall is absent.

Hence, in the onion cells, the cell wall around the cell would be clearly visible, whereas in the case of cheek cell, the cell would only be lined by a cell membrane, a cell wall would not be present.

Further, the plant cell would have the chloroplast, as they perform photosynthesis, but the animal cell would not have chloroplast. Unlike animal cell, the central vacuole in the plant cell is bigger and clearly visible.
