1) Variation: there needs to be a difference in the individuals within a population
2) Inheritance: These variable traits must be able to be passed down genetically
3) Growth rate: There needs to be a growth rate that requires a struggle for resources
4) Survival rate: There needs to be a difference in survival rate for the different variation types... certain variations will live
now i may just not understandthe question here but its probs D
Answer:
Pollution can impact other spheres
Explanation:
Okay here ya go :)
As more and more pollution occurs it can cause the ozone layer to slowly start to decay in a way as the sphere get thinner. What this impacts is the troposphere. Since the ozone layer starts to fade away it can't filter out as much harsh rays from the sun. Those rays eventually get to the earth's surface and bounces off the surface warming up the earth causing life to be affected in the troposphere by warming up the earth.
Weight is measured in Newtons, mass is measured in kilograms, mass does not change when gravity changes; weight does, mass is the amount of matter in an object, and weight is a gravitational force
