Answer:
high clean-energy startup costs
Explanation:
Protecting the environment means improving its sustainability and reducing pollution to the barest minimal. This utterly means terminating every activity that contributes to pollution in the environment, including the source of energy. The most widely used source of energy is the non-renewable source e.g. coal, fuel, etc.
These source of energy, however, release pollutants in form of greenhouse gases, into the environment. One way to eliminate the use of non-renewable source of energy is to adopt the use of renewable sources e.g. solar energy, wind etc. However, one major setback to doing this is the high production cost involved.
Although these sources of energy (renewable) are referred to as green or clean, but they have really expensive startup costs and are unaffordable most times.

Carry out and experiment.
E.g. put a cut stalk into a beaker of colored water. The color of the water can be red, blue, yellow, etc.
The answer is B: it creates offspring from parents
Answer:
The difference is:
a) Positive feedback increases a change while negative feedback reduces a change.
b) Positive feedback occurs specific situations while negative feedback occurs in the body.

d) Positive feedback has less frequent mechanism while negative feedback has more frequent mechanism.
e) Positive feedback enhances change while negative feedback resists change.
f) Positive feedback has a wider range while negative feedback has a narrow range.
