Answer:
C) Commensalism has no effect on the species, while parasitism has a negative effect.
Explanation:
Commensalism and parasitism are both forms of species interaction.
Commensalism:
Commensalism refers to an ecological relationship between two species where one species benefits from the other but the other is neither harmed nor benefited. For example, remoras are little fish that attach to sharks and other larger fish. Remoras benefit in terms of protection, transport and food. They feed off scraps attached to the shark's mouth and teeth. However, the shark neither benefits nor suffers from this interaction.
Parasitism:
Parasitism is a relationship between a host and a parasite where the parasite benefits at the expense of the host. the parasite attains benefits while harming the host. For example, ticks and fleas that infest dogs. The ticks attain nutrients from the host's blood and in turn, weaken and harm the host.
Answer:
16 square inches
16 inches
Step-by-step explanation:
We know the area formula is A = s² and the perimeter formula is P = 4s, where s is the side length.
Here, s = 4, so plug this value into both equations:
A = s²
A = 4² = 16 square inches
P = 4s
P = 4 * 4 = 16 inches
Both blanks are 16.
Answer:
A.. 2
C.. 5
E.. 10
Step-by-step explanation:
If x represents the number of cars that wash Aron, then the domain of x must contain only integers and positive numbers (natural numbers)
This, because Aron can not wash -3 cars, it would be absurd then for x to be a negative number.
In the same way Aron can not wash 1.29 cars. Or washed 1 car or washed 2, it is not consistent in this case to say that washed a car and a half, for example.
Therefore the correct answer is the options.
A.. 2
C.. 5
E.. 10
