The hereditary patterns of a plant species can be seen by observing the physical traits of two individual “parent” plants and then noting the traits of the “daughter” plants. Though many plants can be studied in this way, some are more useful than others in drawing predictive conclusions.

The time rate of change of displacement is called velocity. As distance is to displacement, so speed is to velocity: the crucial difference between the two is that speed is a scalar and velocity is a vector quantity. In everyday conversation, we usually say speed when we talk about how fast something is moving. However, in physics, it is often important to determine the direction of this motion, so you’ll find velocity come up in physics problems far more frequently than speed.
If a body covers a displacement of 50 meters in 10 seconds. What is the velocity of the object?
Definitions of different types of mixtures:
Solution: Molecules of one or more substances are distributed uniformly among molecules of another substance.
Suspension: Small particles of a substance are dispersed throughout a gas or liquid; the particles settle to the bottom if left undisturbed.
Colloid: Very small particles of one substance are distributed evenly throughout another substance; particles are smaller than those of a suspension and do not settle.
Which of the following is an example of a suspension?
