Answer:
Explanation:
About 3% of total water on the earth surface is derieved from fresh water sources.
Given that, the total volume of water on the earth surface = 1,386,000,000km³
Volume of fresh water = 3% x 1,386,000,000
= 41,580,000km³

Invasive species are animals or plants from another region of the world that don’t belong in their new environment. They can be introduced to an area by ship ballast water, accidental release, and most often, by people.

Answer:
a) Control Center
b) Effector
c) Receptor
Explanation:
Homeostasis is maintained by feedback loops. The receptors serve to sense the changes in the variables (the stimulus) and send the information to the control centers.
The control centers, such as the brain, serve as integrator and analyze the changes sensed in the particular condition. Control centers also send signals to the effectors to generate a specific response. The response serves to counteract the changes in the variable and restore it again to the set point.
For example, thermoreceptors present in the skin layers sense the changes in temperature of surroundings and send the information to the brain. Brain commands effectors to generate a response to maintain constant body temperature. Effectors are muscles and glands mostly.
