Suppose that several organisms from a strain of bacteria inherited a mutation that increased their resistance to antibacterial d

rugs. Over time, the drug-resistant bacteria increasingly outnumbered the bacteria that did not have the mutation. This example best illustrates ___________.

Answer:

Natural selection

Explanation:

Natural selection is a process where some organisms are able to reproduce more and survive better due to the presence of beneficial genetic traits in them. The other organisms of the same population that lack these traits are not able to survive and reproduce in the same way. The bacterial having drug resistance are able to survive in the presence of drugs in the surroundings. These bacteria will reproduce more and leave more progeny. Over the generations, the proportion of the bacteria with drug resistance will increase. This represents an example of natural selection.

Explain why you would sooner be hit by a ping pong ball vs a baseball. Use all the terms: force mass and acceleration!!
kati45 [8]

Answer:

Because the ping pong ball has a lesser mass than a baseball; hence the ping pong ball will accelerate faster than the baseball when a constant force is applied to both

Explanation:

The force applied to an object is a product of its mass and acceleration i.e. F=ma. According to Newton's second law of motion, the relationship between the mass of an object and its acceleration when force is applied to it was described.

In a summary, the second law states that that the acceleration of an object increases with increased force and decreases with increased mass. This means that the more the mass of an object, the greater the force needed to make it accelerate and also the more the mass, the lesser it accelerates.

In this case, a ping pong ball has a lesser mass compared to a baseball, hence, it will accelerate faster than the baseball assuming an equal force was applied. Since the ping pong ball will accelerate faster, it will hit a person faster than the baseball.

The consistent reduction in fitness (survival, reproduction, etc) in a population due to widespread non-random mating is called
igomit [66]

Answer:

Natural selection

Explanation:

Natural selection occurs when one allele (or combination of alleles of different genes) makes an organism more or less fit, that it is able to survive and reproduce in a given environment. If an allele reduces fitness, its frequency will tend to drop from one generation to the next.
