Which of the following is true about the diversity of organisms on earth? a. organisms on earth are not influenced by changes in either internal or external factors. b. the diversity of organisms on earth results from random changes in an organism's genetic code only. c. the diversity of organisms on earth results from both external and internal factors. d. the diversity of organisms on earth results from changes in an organism's external environment only.

I believe the answer is C because the environment could change and hurt or help a species (external) but a species could also be prone to getting diseases that hurt the population or they could eat something deadly which in turn kills large numbers (internal)

Explanation:

a warm, wet climate will produce the highest rate of weathering. the warmer a climate is, the more types of vegetation it will have and the greater the rate of biological weathering (figure below). this happens because plants and bacteria grow and multiply faster in warmer temperatures.

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.
