Vacuoles are important for _storage_
Explanation:
The vacuole in plant cell are large structures that act like ‘back-packs’ for the cell. They store salts, nutrients like glucose, minerals, and even some proteins and pigments. These materials are then utilized by the cell whenever they are needed. The vacuole also stores waste products from the cell’s cellular activities.
The fact that the vacuole stores all these materials, most of which have osmotic potential, it becomes an ideal organelle to maintain cell's turgor pressure. Water diffuses into the vacuole, via osmosis, because the vacuole is hypertonic to its environment. The vacuole, therefore, ‘swells’, and so does the cell. This causes the cell to be turgid. Turgidity is very significant for support in non-woody plants.

Answer:
Part C
because rotating the 3 knobs will increase magnification for more or less visibility depending on what you want to see relating to the size of the microscopic or eye-visible image.
Answer:
The steps that can be seen in this story are observation and the questioning phase, which can also be called elaboration of the problem.
Explanation:
The scientific method is a set of phases that are able to guide researchers to the creation of scientific knowledge, through an experiment. This method is essential for conducting scientific research, allowing an experiment to be managed in a way that promotes answers to scientists' questions. The scientific method presents the phases called observation, questioning (or elaboration of the problem), elaboration of hypotheses, experimentation, analysis of the results and conclusion.
In the story shown in the question above, we can see the phases called observation and questioning. The observation takes place the moment Fleming noticed a fungus capable of growing on colonies of bacteria that cause throat infections, killing them. This observation made him enter the questioning phase, when he wondered if the fungus was able to prevent the growth of these bacteria.
At individual level i believe the mechanism of bacteria survival is brought about by the ability of bacteria to survive in extreme conditions such as extreme heat, cold, dehydration, and large amounts of ultraviolet rays. At population level, bacteria can produce quickly and their population grows rapidly.
C) Density of the animal population Animal population is the only biotic or living factor. Grazing by herbivores, like sea turtles, will affect seagrass populations. Too many herbivores, not enough segrass.
