Kevin and Jason are riding identical bicycles to school. The boys both have the same amount of mass. Kevin is traveling at 20 kilometers per hour, whereas Jason is traveling at 15 kilometers per hour.
Which is true?
A. Kevin and Jason have the same amount of kinetic energy because they are both in motion.
B. Jason has more kinetic energy than Kevin because he is moving at a faster speed.
C. They have the same amount of kinetic energy because they have the same amount of mass.
D. Kevin has more kinetic energy than Jason because he is moving at a fast speed.

Kinetic Energy= 1/2 mass*speed^2
so which of them has a greater speed?

The Answer Is D
Answer
Pollinators, like bees, help plants reproduce. They do this by moving pollen from one part of a plant to another. Because of their role in plant reproduction, pollinators are critical to farming and food production.
When new farms are built, a lot of native plants are removed and replaced with just a few crops. This loss of biodiversity decreases food sources for pollinators, many of which have specific needs. As a result, the number and types of pollinators can decline. This decrease in pollinators can reduce the ability of a farm to produce food.

Replacing crops that require pollinators with those that do not.
C.
Releasing non-native pollinators onto farms.
D.
Planting native vegetation on some sections in and around farms.
