Answer:

The correct answer is option d. "Elastic channels".

Explanation:

The vascular plants uses xylem and phloem cells that carry water and nutrients to all the parts of the plant, which are present in the leaves of the plant. Stomata is part of the vascular system of a plant, but it serves for gas exchange instead of water and nutrients exchange. Palisade mesophyll is a structural component that contains columnar cells with spaces between them, located in the leaves of vascular plants as well. A component that is not part of the vascular plant leaf anatomy are the elastic channels.

Answer:

An identical setup but replacing the enzyme with an equal volume of water

Explanation:

When carrying out any experiment, it is important to set out a control in order to increase the reliability of the data and results.

The control minimizes the effects of variables other than the independent variable.

In the above experiment, starch has to be eliminated and replaced with water. Water does not have starch hence the digestive enzyme being tested will not have any effects making the data and results from the experimental group reliable.

The diagram represents a model of DNA replication.

mr_godi [17]

Although there is no attachment, the best answer would be option B.

DNA replication occurs in opposite directions along a strand of DNA.

The leading strand is replicated continuously in the 5' to 3' direction towards the replication fork.

The lagging strand is replicated discontinuously in the 5' to 3' with segments of DNA known as Okazaki fragments.
