scoundrel [369]

Answer:

C) Commensalism has no effect on the species, while parasitism has a negative effect.

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 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.

For sisters bought a present for their father. They recieved a 10% discount on the original price of the gift . after the discou
Basile [38]
Since they each paid the same amount, we can figure out that 9*4=36 dollars is the price of the gift. Next, since there was a 10% discount (or 0.1 by moving the decimal 2 spots to the left), we can say that the original gift price is x and 
x-0.1*x=0.9*x due to that we subtract the 10% discount (and it's 10% of the original price). In addition, the sisters paid 0.9*x, which is 36. Dividing both sides by 0.9, we get x=40

The difference of a number and 6 is the same as 5 times the sum of the number and 2. What is the number?
bulgar [2K]

Answer:

A

Step-by-step explanation:

let the number be x, then

the difference of x and 6 is x - 6 and

5 times the sum of x and 2 is 5(x + 2)

Equate both expressions

5(x + 2) = x - 6 ← distribute left side

5x + 10 = x - 6 ( subtract x from both sides )

4x + 10 = - 6 ( subtract 10 from both sides )

4x = - 16 ( divide both sides by 4 )

x = - 4 → A
