Answer:
an advantage is living cells can be examined in their natural state without previously being killed, fixed, and stained
Answer:
Explanation:
they can not chose to adapt. adaptations occur over a very long period time(darwinism) Evolution is not selective in the sense that the organism being changed can choose.
1. The sun's position changes,because the Earth turns on its axis,which causes the sunlight to hit at different angles. This means that after a period of time,the sun no longer shines on one side. It will be dark/night on one side and light/day on the other side.
2.Shadows change,because the angle that the light hits us is different overtime.
3.The flagpole will look the same from when it started at the exact time.
4.Overtime our shadows become small and you may not be able to see it. That is mostly for small objects.You can see the but for small and certain angles.

Ecotourism is when people are encouraged to tour natural environments, often of endangered species, in order to observe wildlife. You see, when people can see the beautiful places in nature that are at risk, they will work to conserve the environments. Transportation through these places uses the land as a resources without taking anything from it. Non-Extractive Resources are pieces of land and places in nature that benefit the economy without people extracting resources or artificially developing things within the ecosystems.
Metals on the ocean floor aren't renewable. They are formed over long periods of time, and the organisms that feed on them will become extinct without it. For example, iron is one of the most heavily mined metals in the ocean, as well as a primary food source for phytoplankton—who are one of the species at the base of the marine food pyramid, meaning they are essential to the survival of other species.

1. The right answer is Vacuoles.
Vacuoles is a characteristic organelle found in plants and fungi.
In addition to the important role for cell turgor (regulation of the shape of the cell by osmotic pressure), the huge vacuole that exists in most cells plays multiple roles of waste storage, sometimes reserve and most often maintenance of cell composition.
2. The right answer is cell wall.
The wall is the outermost envelope of the plant cell. It is essentially composed of carbohydrate polymers, cellulose and pectin, proteins and possibly other compounds of phenolic nature (lignin and suberin). The wall is composed of three essential parts: the middle lamella, the primary wall and the secondary wall.
