Answer:

<h2>Parasitism.</h2>

Explanation:

Parasitism, in biology, is defined as a relationship between different species, formed by a parasite and a host. So, basically the parasite lives in or on the host, causing it harm. <em>Parasites can be describe as predators that eat less than one prey unit</em>, that is, they feed them selves slowly, they don't kill the prey instantly as actual predators do.

So, in this case, we are talking about leeches, which are defined as parasitic worms which lives in freshwater environments. They feed themselves by sucking blood from the host.

<em>Therefore, the relation between these two species is Parasitism.</em>

If it takes 100 N to get a 10 kg object to accelerate at 10m/s/s, how much force will it take to get a 20 kg object to accelerat
yan [13]

Answer: C) 200 N

Explanation:

The force F is defined as:

F=m.a

Where:

m=20 kg is the mass of the object

a=10 m/s^{2} is the acceleration

Then:

F=(20 kg)(10 m/s^{2})

Finally:

F=200 N

Hence, the correct option is C.

The manufacturer of a 6V dry-cell flashlight battery says that the battery will deliver 15 mA for 60 continuous hours. During th
Vaselesa [24]

Answer:

16200 J

Explanation:

t = Time the battery is on = 60 hours

I = Current = 15\times 10^{-3}\ A

Average voltage

V=\dfrac{6+4}{2}=5\ V

Energy is given by

E=V\times I\times t

\\\Rightarrow E=5\times 15\times 10^{-3}\times 60\times 3600

\\\Rightarrow E=16200\ J

The energy delivered in the given time is 16200 J

How is light reflected from a prism​
Ivenika [448]

Answer:

White light entering a prism is bent, or refracted, and the light separates into its constituent wavelengths. Each wavelength of light has a different colour and bends at a different angle. The colours of white light always emerge through a prism in the same order—red, orange, yellow, green, blue, indigo, and violet.
