The correct option is this: HE COULD DETERMINE WHETHER THE HYPOTHESIS IS BASED ON REPEATED EXPERIMENTS.
An hypothesis is a proposed explanation based on prior knowledge which serves as a starting point for scientific experimentation. After the experiment, if the hypothesis is confirm to be true and other scientists test it also and find it to be true, then the hypothesis can be regarded as theory, because it has been tested many time and find to be true.<span />

Answer;
b. The cells appear well-defined, indicating the presence of cell walls.
Explanation;
Although, the overall function of the cell is the same, there are some important differences between animal and plant cells.
The first difference is that plant cells have an organelle called chloroplast. Chloroplasts contain a pigment called chlorophyll (which gives the plant its green color).
-Additionally, animal cells are smaller than plant cells and have a membrane around them that is flexible and allows molecules, gases and nutrients to pass into the cell. Plant cells are larger and in addition to a membrane they have a rigid cell wall. The cell wall does not let any material pass so instead the plants cells must have tiny openings between cells like doors between rooms in your house.
DNA replication is the process by which two DNA molecules are produced from one parent DNA molecule. DNA replication is semi conservative, this implies that, each strand in the double helix DNA molecule act as a template for the synthesis of a new, complimentary DNA strand. Because semi conservative method has a DNA template that is already accurately formed, the probability of having errors in the newly formed strand is drastically reduced.
