Fossils tell u if something has been there or not and u study it in some classes or jobs
This was Lamarck's idea. Here's an example: Suppose giraffes originally had short necks that they stretched to reach high-up leaves in the trees. This continuous stretching of the neck was passed onto offspring, who as a result had slightly longer necks. This continued for multiple generations until we get today's long-necked giraffe. Lamarck was on to something (that something being evolution by natural selection, which Darwin discovered), but his theory wasn't completely correct since organisms can only pass on genes (segments of DNA that code for a characteristic or function) to their offspring. Since "stretching" would not code into DNA, it wouldn't be passed onto offspring, proving Lamarck's theory incorrect.
Osmosis is a process where molecules of a solvent travel through a membrane from a less concentrated solution to a more concentrated one.
Answer:
The correct answer will be option-E
Explanation:
Cyanide is a poisonous substance which is considered the inhibitor of the cellular respiration. The cyanide inhibits the process by inhibiting the complex IV which transfers the electrons to the oxygen thus, block the transfer of the electron.
The isotonic solution is the solution which contains an equal amount of solute to the cell, as a result, no osmotic gradient develops. This leads to the no movement of solute across the semipermeable membrane. When a cell is placed in the isotonic solution, the cell remains unaffected.
Thus, option-E is the correct answer.
The two lower chambers of the heat, which recurve blood from the atria and pump it into the arteries
