Yeah no one is gonna read all if this lol
Answer:
Elastic collisions are collisions in which both momentum and kinetic energy are conserved. The total system kinetic energy before the collision equals the total system kinetic energy after the collision. In the collision between the two cars, total system momentum is conserved.
Answer: Epidemiology
Explanation:
Epidemiology is a branch of medicine, the study of human health and disease at the population level. Epidemiology deals with the incidence, distribution, prevalence and possible control of diseases and other factors relating to health. By tracking the cause and distribution of the disease among many individuals of the population, epidemiologist can identify potential stategies for the preventing and controlling of diseases and disorders.
Answer:
The likely explanation is that population 1 had traits which were more favorable to its survival than population 2's in the new conditions. It wouldn't have to do with food competition, but the traits they already have that may or may not be conducive to their survival in the new conditions.
Explanation:
Let me explain. Say a drought occurred on an island. Population 2 relied on eating bugs that lived in the green grasses. Population 1 relied on eating cactus fruit, which is drought-resistant. Say that because of the drought, population 2 started to decrease since there were less bugs to eat because the grasses dried up. Population 1 is unaffected because the bugs they eat were still in abundance.
This all has to do with the concept of natural selection. Species with traits that are good for their environment will likely do well unless a change in conditions occurs which makes their traits no longer favorable.
Hope that makes sense!
