Explanation;
-With negative feedback, the output reduces the original effect of the stimulus. While in a positive feedback system, the output enhances the original stimulus.
-Negative feedback is the most commonly used feedback loop in the body. Negative feedback is used to negate or counteract a stimulus without completely eradicating it.
-One key difference between the two feedback is that positive feedback loops are used to eradicate a stimulus. Another key difference is that responses through positive feedback become more amplified over time. So once a stimulus activates a positive feedback loop it is not turned off until the stimulus is completely removed.
49 Kelvin = -224.15 Celsius
I believe this is the answer.

Explanation
The process by which a large nucleus split into two smaller nuclei is called nuclear fission and occurs after the nucleus has absorbed a neutron that is a product of the radioactive decay of another atom. The formed fission fragments are unstable and extremely radioactive.
Answer:
Vector
Explanation:
<u>Diseases can be transmitted by the mechanical or the biological vector. Vector is an animal (typically can be called as an arthropod) which carries disease from one host to another. </u>
Mechanical transmission is the one in which an animal which carries the pathogen from on host body to the another without being infected by it. It is facilitated by the mechanical vector.
Biological transmission is th eone which occurs when pathogen reproduces within the biological vector which transmits pathogen from one host body to the another.
Answer:
D
Explanation:
Units of weight and volume won't be large enough to be meaningful. so liters and grams are too small. Find out the weight of a cubic meter of water and then estimate how many cubic meters there might be in a lake. Millions would probably be too small.
Miles are too big. Most lakes do not go to a depth of 1 mile, but you on on the right track. Distance is what you want.
Meters are the answer.
