In secondary succession, the pioneer species are plants that are adapted to exploit disturbances rather than bare rock. They typically include plants such as grasses, birch trees, and fireweed. Organic matter from the pioneer species improves the soil so other trees and plants can move into the area.
Answer;
Low power lens
Explanation;
-When focusing on a slide, it is important to always start with low power objective lens (4X or 10X). The 4x objective lens has the lowest power and thus the highest field of view. As a result, it is easier to locate the specimen on the slide than when you start with a higher objective lens.
-Once you have the object in focus, then switch to the next higher power objective. One should then focus again on the image and then switch to the next highest power such as 25x, 40x, etc.
One cell. Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism, while multicellular organisms use many different cells to function.
Industries such a beer are very dependent on alcoholic fermentation. The alcoholic fermentation process allows the yeast (which is used to make beer) to convert simple sugars into ethanol and carbon dioxide. Another industry that is dependent on this process if bakeries. People that make bread need this process because in this process the yeast cells break down the sugar into carbon dioxide and water. Then each yeast cell form a center around carbon dioxide bubbles that form. This makes the bread increase in size and rise as each yeast cell fills up with carbon dioxide/gas.
I hope this helped :) Please make brainliest if you can :)
They are examples of a wet zone!
Hope this helps!
