Adot is drawn every second to show the position of a toy car coasting up a ramp. which statement best describes the motion of the car?

it is slowing down because less distance is covered every second.

the car is stationary, then slides back down because the ramp is so steep that it can’t coast up at all.

it is speeding up because more distance is covered every second.

the speed is constant because the distance between the dots remain the same.

answer; i believe the answer is hydraulic action;

the contamination

we are putting to many trash.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
