Answer:
In the past was believed that species were fixed entities
Explanation:
Before Darwin's evolutionary theory (in which all living things arise through descendants with modification), Linnaeus had proposed that species were immutable entities. Although it was an erroneous concept, this belief enabled the development of a system for classifying and naming organisms. Indeed, Linnaeus is nowadays recognized as the father of taxonomy to create this system. This example shows that scientific knowledge is not based on factual information, but it is a process that progressively increases our understanding of the real world.
What factors do ride engineers have to consider when designing roller coasters to give riders a thrilling experience that is also safe?
Answer:
Ride engineers have to consider weight of a person, color of their skin due to heat effectiveness, sea level due to differentiation in G force with gravity and finally, speed for the g force experience.

Two friends push with great force against a rock. The forces are equally strong but in opposite directions. A heavy box rests on top of the rock. Answer these questions about the motion of the rock. Assume that the rock is light enough for either friend to carry.
Does the rock move? If so, in which direction does it move? Explain.
Two friends push with great force against a rock. The forces are equally strong but in opposite directions. A heavy box rests on top of the rock. Rock does not move because equal forces are applied on both sides.
What is force ?A force is an influence that has the power to alter an object's motion. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to define force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.
Force is used to describe a body's tendency to alter or change its condition as a result of an external cause. When force is applied, the body may also alter its size, shape, and direction. kicking a ball, opening and closing doors, or mixing dough are some examples.
Thus, rock does not move because equal forces are applied on both sides.
