Answer:
cells from which all other cells with specialized functions are generated.
Explanation:
they may be used by dividing into two or more cells called the daughter cells
Answer:
1.A tissue is a collection of similar cells that work together to perform a specific job.
An organ is a collection of different tissues that work together to perform a specific job. The function of a part of an organism is what it actually does (it's job)
2.The structure of the alveoli as a web of blood vessels surrounding an air sac allows blood cells take in oxygen and bring it into the lungs (organ)
Answer:
Cephalization does not confer an advantage to free-floating or sea organisms. Many aquatic species display radial symmetry like the jelly fish for instance.
Aquatic animals are not cephalized because they must be able to find food, take caution and defend themselves from harm from all directions.
Answer:
Hmm.
Explanation:
Cell division is the process by which a parent cell divides into two or more daughter cells.
There ya go!
Definition : "Cellular respiration<span> is a set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products."
Simplified : </span>Cellular respiration is used to take in food, then is used to create ATP. ATP is a chemical the cell uses for energy. This process is called aerobic respiration. The process uses oxygen, and has four stages known as Link reaction, glycolysis, the Krebs cycle, and the electron transport chain.
You might want to re-word the simple version a little, I worded it the best I could but I used information from wiki.
