4 0
The atmosphere is 78% Nitrogen, 29% Oxygen, 0.9% argon, and the remaining gasses (methane, CO2, Ozone...) only appear in trace amounts *this does not mean that there isn't a lot of these "trace" gases, the atmosphere is very very very big, and a few millionths of CO2 can wreck the whole thing.

Which characteristics can be used to classify the tree as a gymnosperm rather than “any other type of seed” plant?
erica [24]
1. Naked Seeds, Gymnosperm means 'naked seed' and these were the earliest trees to evolve. They do not produce flowers and have seeds which are directly exposed to the air for wind pollination. Pine cones are one example. For ease you might think of the gymnosperms as conifers, such as yew and Scots pine.

For science class, your teacher gives you and your partner a ball. She asks you to figure out a way to balance forces that you a
UkoKoshka [18]

Answer:

A.Both of you pull with equal force on opposite sides of the ball.

Explanation:

Balanced forces means that the total force or the sum of the force done on the object should be equal to 0 newtons or in other words, it should not be moving.

Force is defined as the push or pull on an object. For both people to balance out the forces on the ball while both applying a force, you need to do this from opposite sides.

You could either pull with equal forces on opposite sides of the ball or you can push with equal forces on opposite sides of the ball.

→ ball ←

← ball →

For the other choices, if you both push or pull on the same side, the ball would move that direction because there is no opposing force.

ball → →

If one pushes while the other pulls on opposite sides, it will move the direction you are pulling and pushing.

→ ball →
