Answer:
C. When exposed to antibiotics, most bacteria in a population die but some survive and live to reproduce.
Explanation:
Darwin suggested natural selection as the mechanism that explained the evolution of species. This idea states that a population of individuals living in a certain environment is adapted to thrive in it. However, if there is a change in the environment, individuals must adapt in order to survive, otherwise they will die. Only a handful of individuals which had a particular (and random) variation before the change of the envirnonment will be able to adapt and survive. If the variation is heritable, the next generation will have that same trait and will be able to thrive in the new environment.
In the answer C., a population of bacteria is composed of some individuals which are susceptible to the antibiotic and some individuals that are resistand because they possess a mutation in their DNA that allows them to survive an environment with antibiotics. If no antibiotic is present, then both types of bacteria can survive. However, if they are exposed to the antibiotic, the previously resistant bacteria are the only ones that will be able to survive and reproduce.
Answer;
True.
When the northern part of the earth is farthest away from the sun it gets cold and the other side of the earth gets warm / summer
Explanation;
The Earth's orbit is not a perfect circle, but a bit lop-sided. During part of the year, Earth is closer to the sun than at other times. However, in the Northern Hemisphere, we are having winter when Earth is closest to the sun and summer when it is farthest away.
When it is Summer in the Northern Hemisphere, it is Winter in the Southern Hemisphere, because the Earth is tilted on its axis.
