Fiddler Crabs usually eat microscopic dead organic matter, plants, algae, and other small animals. They usually find their food in the sand or mud.
land Hermit crabs usually eat a variety of things, such as fallen fruits, decaying wood, leaf litter, plants and grasses and items washed ashore by the tide, and they might even eat feces.
we, Humans do eat fiddler crabs and most of the fish will inhale these tiny crabs.
again, humans eat hermit crabs too, most fishes, crabs, octopuses and birds eat them too

Answer:
b) Insoluble in water
Explanation:
Lipids or fats are water-insoluble organic molecules and soluble in certain organic substances such as alcohol, ether and acetone.
Lipids can be found in plant and animal foods and should be consumed in a balanced manner. These molecules have functions such as energy reserve, thermal insulation and vitamin absorption.
Lipids are esters, meaning they are composed of one acid molecule (fatty acid) and one alcohol molecule (glycerol or other). They are insoluble in water because their molecules are nonpolar, that is, they have no electric charge and therefore have no affinity for the polar molecules of water.
Answer:
Sodium ions pass through channels in the hydrophobic barrier that have been formed by membrane proteins. The crossing membrane is called facilitated diffusion because it is facilitated by the channel
Potassium ions have to be transocated through specific membrane transport proteins. It is then transported into the cell through potassium pumps with energy being consumed int the form of ATP.
The sodium-potassium pump goes through cycles of shape changes to help maintain a negative membrane potential. In each cycle, three sodium ions exit the cell, while two potassium ions enter the cell. These ions travel against the concentration gradient, so this process requires ATP.
