Harvester ants often strip a bush of all of its leaves. Some people believe this helps the plant grow thicker, healthier stems.

In an experiment, a student stripped off all the leaves from a set of plants. In a second set of identical plants, the student allowed ants to strip off the plants' leaves. In order to improve this experimental design, it is most important to add a set of plants

Answer:

The correct answer will be- the control group of plants with leaves on them.

Explanation:

Harvester ants are the ants which collect the seeds of the plants and store them as a source of food in their nests in soil.

The experimenter observes that stripping of the plant leaves by the ant increases the thickness. The experiment was designed to study the thickness of the stem with one group in which the leaves were stripped by the humans and one group with leaves stripped by the ants.  

These cases represent the experimental groups in which stem thickness will differ but it lacked the control group which will have the plants with their leaves present on them and preventing them from stripping by human and ants.

This control group will provide a reference to the experimental groups and will improve the experiment.

Thus, the control group of plants with leaves on them is the correct answer.

In comparing several populations of the same species, the population with the greatest genetic variation would have the greatest
babunello [35]

Answer:

The population with the greatest genetic variation may have:  

- The greatest number of alleles per gene

- The largest gene pool

Explanation:

A higher number of alleles will produce a higher total number of protein forms per gene. Moreover, the largest gene pool will synthesize the largest content of proteins, thereby increasing variation

Which plant cell organelle helps maintain the shape of the cell by helping to maintain turgor pressure? A) cell membrane B) cell
ZanzabumX [31]

Answer: The correct answer is- C) vacuole.

Large central Vacuole is a specialized fluid filled organelle, present only in plant cell. It is primarily involved in providing support and shape to the plant cell by maintaining the turgor pressure ( a hydrostatic force that is produced due to the cell contents against the inner side of the cell wall). The central vacuole stores water ( that flows through osmosis) and maintains turgor pressure in a plant cell.

Turgor pressure provides mechanical support and helps in the growth and development of plant.
