The answers are solution, colloid, and suspension respectively.
NaCl or salt is dissolved in the blood. So this makes blood and salts a solution. You won't be able to discern the NaCl in a solution of blood and NaCl.
Proteins in the plasma make blood a colloid. Protein particles are bigger than particles in a solution but are smaller than particles in a suspension.
Lastly, blood cells and blood make up a suspension. You would notice this characteristic in blood because red blood cells settle.
You can observe this when your blood is drawn. When it is placed in a test tube and left alone or placed in a centrifuge. The components separate into liquid on top, where you cannot see particles like salt; plasma in the middle, which has pale yellow color and also contains proteins; and the red blood cells at the bottom that settled.
Answer:
homologous structure
analogous structure
natural selection
This is known as an analogous structure.
To make this determination, you need to think about if the features are the same in function or also in structure. Features that have a closely related structure and function are likely to be related.
To learn more about why your friend is in the hospital, you should research vestigial structures.
These two beetles aren't closely related, but they look and behave similarly. This is because they live in the same environmental conditions and likely share a common ancestor that lived in Gondwana (the supercontinent that included the southern continents before they split apart through plate tectonics).
Australia has so many genetically distinct organisms because it has been separated from other bodies of land by water for a very long time. This has created an opportunity for long-term independence of other geographic areas.

The simplified drawing shows how changes in polar vortex winds high in the stratosphere can influence the North Atlantic to cause changes in the global "conveyor belt" of ocean circulation.
Hello. You have not submitted the experiments to which this question refers, which makes it impossible for it to be answered. However, I will try to help you in the best possible way.
A dependent variable is one that is influenced by an element, in order to present a result, that is, it is a variable that does not establish itself, being dependent on another variable to establish itself. An example of a dependent variable can be seen in an experiment that seeks to determine the differences in growth rates of bean plants that were fertilized with different organic fertilizers. As you can see, this is an experiment where the different organic fertilizers influence differences in the growth rate of bean plants. Thus, the growth of these plants depends on the fertilizer, this growth being the variable dependent on the experiment.
A control group, in turn, is an element of the experiment that does not receive the element that is being tested in the same experiment. The control group is important, because it allows the researcher to see the results of a system where the tested element does not exist, thus being able to determine the real differences that the tested element is capable of causing. Using the same example presented in the paragraph above, we can see that the different organic fertilizers are the elements tested in the experiment. These fertilizers will be applied to the plants, however it is important that at least one of these plants does not receive any fertilizer, so that the difference between a system with fertilizer and a system without fertilizer can be evaluated. This plant that received no fertilizer is the control group.
