Answer:
The correct answer is "a hypertonic solution".
Explanation:
Seawater is the most clear example of a hypertonic solution in nature. The concentration of ions in seawater are far more superior than the concentration of ions inside a plant or an animal cell, since seawater have an osmolarity of about 1000 mOsm/l. Therefore, at high tide a plant or animal cell will be in a hypertonic solution, and the cells must have adaptions to avoid cell shrinking and dead.

Answer:
The amount of energy stored in a molecule of ATP compared to the amount stored in a molecule of glucose is <u>less</u>.
Explanation:
Both ATP and glucose are energy containing molecules. However, a molecule of glucose has about 90 times more energy than a molecule of ATP.
But, ATP is used by most cells as the quickest source of energy. This is because ATP can easily be broken down to generate energy and it transfers energy very effectively.
A molecule of ATP is made up of adenine and three phosphate groups. The bond between the second and third phosphate is broken down to generate energy.
A homologous structure is a structure or organ that can be found on many different animals that suggest that there is a common ancestor. It can be anywhere from a bone to a flap of skin to an organ. A common one to look at is the similarity between a human hand, bat’s wing, whale anterior flipper, and a cat’s paw. All of these have a common, 5-point structure to the bones which suggests that we all come from an animal that had 5 fingers.
