Thematic map is the type of map that would most likely be used to show distribution of soybean farms in Illinois.
A thematic map is a type of map that is specially created to display a certain theme or topic associated with a particular geographic area. A thematic map gives special importance to a certain topic such as the average distribution of rainfall in a particular area. This map uses natural features like political boundaries, coastlines, rivers, and city locations as reference points to improve an individual’s understanding of the map's purpose and topic. Types of thematic map include; choropleth map, dot map, contour map, dasymetric map, and graduated symbols.
Answer: The cell membrane is a bilayer of lipids composed mainly of lipids and proteins.
Explanation: A cell is the functional unit of life. A cell is usually surrounded by the cell membrane. A cell is composed of different organelles such as the nucleus, mitochondria, ribosome, each also surrounded by a membrane and these organelles are suspended in the fluidy part of the cell know as the cytoplasm.
A cell membrane is a thin lining that surrounds the cell and encloses the cytoplasm. It is made up of two layers of lipids in which proteins are embedded. Cell membranes allow the selective passage of materials into and out of the cell.
Answer:
Active transport:
- requires energy
- molecules move from low to high concentration sides
- Na+ and K+ move by active transport
Simple diffusion:
- molecules move from high to low concentration sides
- molecules pass between lipids
- small non-polar and polar molecules
Facilitated diffusion:
- molecules move from high to low concentration sides
- involves channel proteins
- move large molecules
Explanation:
- Simple Diffusion is the pathway of only small molecules that freely move through the membrane by momentary openings produced by the lipids' movements. Diffusion is a slow process that requires short distances and pronounced concentration gradients to be efficient. An example of diffusion is osmosis by which water is the transported molecule.
- Facilitated diffusion is the transport of hydrophilic molecules that can not freely cross the membrane. Channel protein and many carrier proteins are in charge of this transport. When uncharged molecules cross the membrane, they do it according to their concentration gradients, going from the more concentrated side to the lower concentrated one. When ions need to cross the membrane, the process depends on an electrochemical gradient. Glucose is an example of a hydrophilic protein that gets into the cell by facilitated diffusion.
Simple diffusion and facilitated diffusion are both passive transport processes because they only depend on electrochemical gradients, so they do not need any energy to occur.
- Active transport is the transport of molecules that move against the electrochemical gradient, so it does need energy to happen. Molecules move from the lower concentration side to the higher concentration side of the membrane. Carrier proteins are in charge of active transport. The needed energy might proceed from the ATP molecules or the membrane's electric potential. An example of molecules moved by active transport are the Na and K.

Answer:
Oil is the world's primary fuel source for transportation
Explanation:
Fossil fuels mainly coal, Oil and natural gas are the world's primary energy source. Fossil fuels formed from Organic matter over millions of years.
Oil is a source of transportation and it is obtained from the underground reservoirs. Then the crude oil is refined to obtain fuel oil, liquid petroleum, gasoline etc. Crude oil also used to make other products such as pesticides,fertilizers etc
Coal is used to generate electricity. Around 30% of the power supply in United states mainly due to coal. China is world's largest producer of coal and supplied to all over the World.
Natural gas also used to generate electricity, commonly used in buildings and industries.
