Explanation:
Answer:
The mechanisms of transport across the cell membrane are as follow: 1- simple diffusion, 2- facilitated diffusion, 3- primary active transport and 4-secondary active transport
Explanation:
The cell membrane is a selectively permeable structure capable of transporting substances by different mechanisms. Simple diffusion is a type of passive transport (i.e. does not require energy) where non-polar molecules (e.g. O2, CO2) pass across the membrane by a process that does not require energy from the cell. Facilitated diffusion is another type of passive transport where larger polar molecules (e.g., glucose and amino acids) pass across the membrane by using specific transmembrane integral proteins. On the other hand, primary active transport is a type of active transport that uses chemical energy (e.g., ATP) to move substances such as metal ions (Na+, K+, Ca2+) across the cell membrane against their concentration gradient. Finally, secondary active transport is another type of active transport where transporter proteins are used to couple the movement of ions (e.g., H+ protons) down their electrochemical gradient to the transport of another ions/solutes against their concentration/ electrochemical gradient.
The correct answer for the question that is being presented above is this one: "TRUE." <span>Teeth patterns in animals and thorns in plants are examples of characteristics that a taxonomist might observe for keying. The statement show a positive and true idea.</span>
The bison is the primary consumer of the plants which are the producers of the energy which comes from photosynthesis which is powered by the sun.

Some fun fact to me is that you can compare the cell to a factory - I always found it interesting. So the nucleus would be like the CEO, and the Endoplasmic Reticulum (ER) is like an assembly line - it's actually quite similar to a line like this!. And Ribosomes are the workers on this line.
