Scientific research can have a variety of positive and negative impacts on the environment. Many different kinds of research are currently taking place in the Amazon rainforest, including research in the areas of agriculture, medicine,
and sustainability. What might be a positive consequence
of the research that is taking place in the Amazon rainforest?
a. An increase in land available for grazing.
b. The extinction of many species of organisms.
C. A decrease in overall rainforest biodiversity.
d. Discovering compounds that can treat disease.

A or D- most likely D

Explanation:

I don't know if the question is in relation to any specific research, so take it with a grain of salt. A or D make the most sense since B and C are negative impacts to the environment. I hope this helps!

primary succession begins with a bare rock and ends with a forest secondary succession begins after a natural disaster where there is a temporary setback after a forest fire or local destruction, but the surrounding area can fill in

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.
