Answer:
- Erosion and deposition (shoreline retreat)
Explanation:
Sand moves along a shoreline through hydraulic and mechanical action (friction) of the waves. During this course, two phenomenons usually occur, i.e. erosion followed by deposition.
However, sometimes when the wave action is stronger, it leads to the coastal erosion or the shoreline retreat where a land part is permanently lost and the sand is moved with the waves forming beaches.
Answer: Option A) healthy fish populations.
Explanation:
Wetlands include swamps and marsh. i.e areas of land covered with water.
Once, wetlands are destroyed by human activities there would be:
- a reduction in the population of plant and animal that rely on its native organisms due to starvation.
- increased frequency of floods since excess water can no longer be collected there
- pollution of nearby streams as rain will wash off materials into them
However, healthy fish populations does not happen since producers like plankton eaten by the fishes are also destroyed.
Thus, healthy fish populations is the unlikely outcome
Answer:
Tutt suggested that the peppered moths were an example of natural selection. He recognized that the camouflage of the light moth no longer worked in the dark forest. Dark moths live longer in a dark forest, so they had more time to breed. All living things respond to natural selection.
Explanation:
The correct answer is A. Is that which benefits others while causing a disadvantage to the individual.
Explanation:
In biology, altruistic behavior occurs as one organism actions benefit other organisms either because these actions increase the reproductive fitness or the chances an organism survives and prevails over time. Additionally, altruistic behavior implies there is a disadvantage for the organisms acting in the benefit of others. For example, wolves or similar animals take food to those that did not participate in hunting, which means they help other wolves to survive on their own cost as this means less food for those that hunted. According to this, altruistic behavior "is that which benefits others while causing a disadvantage to the individual".
