Define Natural Selection. Explain with an example.
Answer:
Natural selection is to ensure that only the best individuals live. Natural selection does not allow the sick or the incapacitated to survive. But man does not have natural selection, only in some cases. There is also little natural selection on farms.
Natural selection is the process in nature by which organisms better adapted to their environment tend to survive and reproduce more than those less adapted to their environment. For example, treefrogs are sometimes eaten by snakes and birds, evolving long necks has enabled giraffes to feed on leaves that others can't reach, giving them a competitive advantage.

Existing rocks are buried and forced toward the mantle, increasing heat and pressure. This is the first step in the formation of metamorphic rocks.
(PLEASE HELPPPP 90 POINTS!!)
Which best describes the next step in the formation of metamorphic rocks?
Buried rocks melt deep within the mantle.
Lava melts underlying rocks, which crystallize into new minerals.
Rocks that were buried are exposed at Earth’s surface, where they are weathered and eroded.
Magma pockets rise, which increases heat, and minerals change due to temperature and pressure.

Name at least two extinct species that share a close evolutionary relationship with humpback whales.
Explain the similarities and differences that exist between these species and humpback whales.
Is the fossil record complete for humpback whales? Explain your answer.
The two extinct species that share a close evolutionary relationship with humpback whales include dorudon and basilosaurus.
The similarities between these species and humpback whales include the fact that they had tailfins and their elbow joints were able to lock and this allowed the forelimb to have better control and resist the oncoming flow of water as the animal propelled itself forward.
It should also be noted that the hindlimbs of these animals were almost nonexistent and they were so tiny that many scientists think they served no effective function and may have even been internal to the body wall.
The fossil record shows whales' history from the extinct species that lived on land to cetaceans.

The type of asexual reproduction would be seen in a kitchen Binary Fission and budding. In a garden, vegetative propagation, fragmentation, spore formation, and regeneration.
What is Asexual reproduction?Asexual reproduction may be characterized as a mode of reproduction that does not involve the fusion of gametes or a change in the number of chromosomes. In this mode of reproduction, a new offspring is produced by a single parent. The new individuals produced are genetically and physically identical to each other, i.e., they are clones of their parents.
The types of asexual reproduction that can be observed in everyday "real life" are as follows:
Binary fission: Single parent cell doubles its DNA, then divides into two cells.Budding: Small growth on the surface of the parent breaks off, resulting in the formation of two individuals.Fragmentation: Organisms break into two or more fragments that develop into a new individual.Regeneration: The natural process of replacing or restoring damaged or missing cells, tissues, organs, and even entire body parts to full function in plants and animals.Vegetative propagation: It is an asexual method of plant reproduction that occurs in its leaves, roots, and stem.To learn more about Asexual reproduction, refer to the link:
