Answer: 10. Control Group
11. Identify the:
Control Group = Subject A
Independent Variable = The new and original itching powder.
Dependent Variable = The type of itchiness.
Explanation: The Control Group is NOT affected by the experiment. Subject A was given the original itching powder and is not being experimented on with the new itching powder, therefore, Subject A is the Control Group.
The Independent Variable is what you can CHANGE. You control the two itching powders, so you decide which one you give to who. This makes the two itching powders the Independent Variable.
The Dependent Variable DEPENDS on the effects of the Independent Variable. This is what you cannot change, the results. In this case, the type of itchiness experienced and the amount of itchiness experienced cannot be changed, it is a result of the powders, hence why it is the Dependent Variable.
Answer:
Mutualism
Commensalism
Parasitism
Explanation:
In mutualism, both organisms benefit.
<em>Ex</em>. Sea anemone and clownfish. Clownfish gives the anemone food, the anemone allows the clownfish to use it as a home.
In commensalism, one organism benefits, while the other is neither harmed nor benefited.
<em>Ex</em>. Sharks or whales and remora fish. The remora rides along the belly of whales or sharks and when it eats, the pieces that float around, the remora eats the excess.
In parasitism, one organism is benefited, while the other is hurt.
<em>Ex. </em>Dogs and fleas. The fleas are constantly biting and feeding off of the dog's skin. The dog gets bitten and itches a lot.
Mutualism and commensalism are similar because at least one organism is benefited.
Parasitism and commensalism are different because instead of one organism not getting hurt, like in commensalism, that happens in parasitism.
The tortoises have a true bone, your answer would be B)
The most specialized organism is the GRIZZLY BEAR.
Specialized animals refers to those animals, which have different types of cells in their body which carry out different types of functions. Specialized animals are majorly multi cellular animals, whose cells have been differentiated to perform different functions. Examples of specialized cells in humans are neurons, red blood cells, macrophages, myocytes, etc. These cells have specifically adapted structures, shape and composition that made them suitable for the functions that they perform. <span />
