I think the second option is the best (by making the ramps height and length equal) because the first option will require more pushing, the third option will only make the ramp lighter which could cause it to not stay in place, the last option would make it harder to push the boxes up because the rubber will make it harder to slide the boxes up. I hope this helps:)

Answer:
Three types of population distribution:
Clumped.
Random.
Uniform.
Explanation:
1. Clumped:
This is the most common pattern of population dispersion.
organisms are clustered together in a group.
This may reflect the patchy distribution of resources in the environment.
2. Random:
This is a typical distribution where individuals do not interact strongly.
The organism has unpredictable distribution.
3. Uniform:
This is the typical environment where individuals compete with each other for scarce resources like water in the desert.
organisms are evenly spaced over the area they occupied.

The best answer is D.
The mass number of an element is the sum of the number of protons and the number of neutrons. Protons and neutrons both weigh about one atomic mass unit or amu.
The nucleus of an atom is made up of protons and neutrons. Both these two types of particles are almost the same size. Almost all the mass of an atom (99%) is in the nucleus. Atomic mass therefore is really a measure of the size of the nucleus.
