Answer:
The contractile vacuole pumps out excess water and wastes.
Answer:
Cytokinesis
Explanation:
Cytokinesis happens after mitosis. It is the final division to create two new cells. In this phase, the cytoplasm divides and two complete daughter cells are created. These two new cells have genetic information that is identical to the parent cell from which they originated.
Answer:
Predator prey
Explanation:
Animals that feed on other animals are called predators and the animals they eat are called prey. All predators have specific interactions with their prey as they are locked in an evolutionary "arms race". The prey will try to develop novel traits to survive as the predators will try to adapt to these. This is not a conscious process, but rather an evolutionary one, where prey individuals that have a survival advantage will survive and thus reproduce more.
The second image illustrates a predator-prey cycle where an increase in the prey numbers will lead to an increase in the predator numbers. This in turn will lead to a decrease in the prey number which in turn will also lead to a decrease in the predator's numbers.
The third image is a trophic or ecological pyramid in which X are the primary producers (ex. plants), Y are the animals that feed on these (prey) and Z are the predators that feed on Y. In general, top predators are not hunted and eaten by other species which is why they are at the top of the pyramid.
Answer:
The body gets energy from some compounds. Some compounds determine physical characteristics.
Explanation:
Organic compounds control many functions of the human body.
Organic compounds can be made by the body, others can be obtained by a living organism through their diets.
Some organic compounds determine the physical characteristics of a living organism.
For instance, protein
- Make reactions possible in the body.
- Enable transportation of other compounds around the body.
- Provide structure of the body e.t.c
