Answer:
A
Explanation:
The ground is frictionless, which means that the ball won' slow down, until it is out of kinetic energy.
According to Newtons' law of inertia, a body keeps in a state of rest or moving until and unless an external force acting on it. If it continues to moving then it moves in a straight line with a constant speed.
What is inertia?Inertia of a massive body is the tendency to continue in state at which it exists now (rest/moving) until an external force acts on it.
Newtons law of motion says the same that a body at rest tends to continue in rest and a body if moving tends to continue its moving. This is one of the basic law in three law of motion by Newton.
Law of inertia is called the first law of motion by Newton and the second law states the relationship between mass and acceleration and the third law states that every action is accompanied by an opposing reaction.
According to law of inertia for a body at moving continuous to move in a frictionless path in a constant speed. The consistency in speed can only be maintained if the path is frictionless.
Hence, option D is correct. The ball will roll in a straight line with continuous speed.

Answer: Different types of plants use different types of carbon fixation as adaptations to varying conditions.
Explanation: Different plants have evolved different types of carbon fixation methods as an adaptation towards varying conditions
Different types of plants use different types of carbon fixation as adaptations to varying conditions. The statement is True.
What is Carbon fixation?
Carbon fixation is the process by which inorganic carbon, from the atmosphere, is attached to an organic compound, usually a carbohydrate. This process is catalyzed by the enzyme RuBisCO, the most abundant enzyme on earth.
Carbon fixation is a cornerstone when it comes to the process of photosynthesis. Without carbon fixation in the Calvin cycle, photosynthesis would not be able to occur and plants would not be able to make their own food.
Therefore, Different types of plants use different types of carbon fixation as adaptations to varying conditions. The statement is True.

What is the difference between a meteor and a meteorite?
Answer:
meteorites are inside Earth's atmosphere on the ground
meteors are outside Earth's atmosphere
Explanation:
When meteoroids enter Earth's atmosphere (or that of another planet, like Mars) at high speed and burn up, the fireballs or “shooting stars” are called meteors. When a meteoroid survives a trip through the atmosphere and hits the ground, it's called a meteorite.
