endoplasmic reticulum
Protein folding occurs in a cellular compartment called the endoplasmic reticulum. This is a vital cellular process because proteins must be correctly folded into specific, three-dimensional shapes in order to function correctly.
Answer:
An ecosystem only has a certain amount of resources to support a certain number of organisms.
Explanation:
An ecosystem consist of resources and organisms. Resources are the material which are responsible for the survival of living organisms in that ecosystem. Examples of resources are light, water, oxygen and food substance. In the absence of these resources, organisms will die.
Answer:
<em>Evolution</em>
Explanation:
Evolution can be described as the changes which occur in a population over a period of time. Over a period of time, organisms tend to evolve those characteristics which make them better adapted to live in an environment. Such changes which occur over a long period of time are termed as evolution. Charles Darwin was the scientist to bring forward the theory of evolution.
The change in the tail length of a rat over a course of many years is an example of evolution.
Bauxite ore is one of the primary source of aluminum but it must first be chemically processed to produce alumina (aluminum oxide). The next step of aluminum production is smelting of alumina using an electrolysis process (Hall-Heroult process). This electrolysis process is driven by electrical current. Electrolyte (molten salt) with immersed carbon anodes is used in order to dissolve the alumina. Carbon anodes are carrying electrical current and thee chemical bond between aluminum and oxygen in the alumina is broken.
