The answer is; Evolution is occurring in the population
When the gene frequency is changing in a population it means some gene alleles are being slowly eliminated from successive generations and the other is being favored. This means that one allele is giving an advantage in the environment while the other is offering a disadvantage. This is natural selection, which powers evolution., in progress.
Answer and Explanation:
Fossils can be formed in a variety of ways. First and foremost, organisms that possess bones (or shells) are the best candidates for fossilization because these structures commonly remain in fossilizing substances such as mud.
The most preserved fossils come from animals that die in aquatic environments or in environments that have a high level of humidity. This occurs because the animal gets buried in a sediment like mud, leading to the decomposition of soft structures and the fossilization of hard structures, such as bones. As layers of sediment are added, the dead body of the organism becomes a fossil.
Also, animals can leave well-preserved fossils during volcanic eruptions when they get trapped in hot ash flows. In addition, this could also occur in tundra ecosystems when animals get trapped in ice, leaving a well-preserved fossil inside. Moreover, plants are also fossilized, this generally takes place in sediments such as coal.
Finally, paleontologists are able to find the fossils once they become exposed thanks to a process called erosion.
Answer:
Food gives you energy, but oxygen is needed to break down the food into pieces that are small enough for your cells to use This is known as cellular respiration and it is the process of oxidizing food molecules, like glucose, to carbon dioxide and water
