Answer:
Negative feedback occurs when a system's output acts to reduce or dampen the processes that lead to the output of that system, resulting in less output. In general, negative feedback loops allow systems to self-stabilize. Negative feedback is a vital control mechanism for the body's homeostasis.

Explanation:
Scientific measuring tools refers to the equipments or tools use to measure quantities in science examples include measuring cup, measuring cylinder, e.t.c.
The characteristic that describe Scientific tool is that To be accurate, it must be able to make measurements repeatedly over a long period of time because accuracy is how close the measurements for a value is to the correct value and it must take measurements for long period of time without errors.
Answer: I think B . Like the second one

Answer:
The temperature is staying the same. In the graph when it shows solid/liquid and liquid/gas, the temperature stays the same until it changes. This is because it reached it's melting point/vaporizing point. For example, a solid gets heated up, it then reaches it's melting point but it can't go higher than that because it isn't fully a liquid yet, once it's a liquid it will then continue to rise in temperature.
I don't think I put enough detail into that explanation but I hope this helps your problem.
