Answer:
A shore crab can hide in the sand to hide from predators. Shore crabs can also anchoring themselves to the rocks to keep from washing away. Since they are also omnivorous, they eat barnacles, mussels, salt marsh grass, and much more to survive!
Answer:
3. into ice, which is denser than liquid water.
Explanation:
Water molecules are held together by hydrogen bonds. The bonding is usually between the hydrogen atoms of one water molecules, and oxygen atom of neighboring water molecules. Structurally, both oxygen and hydrogen atoms pulls the electon towards themselves.Thus both atoms share electron by covalent bonding.
However, because oxygen has a strong positively charged nucleus it pulls the electron more to itself than oxygen. Thus oxygen is partially negative and oxygen is partially positive. This interactions take place among all the oxygen and hydrogen atoms in water molecules. . The unequal charge distributions is called dipole and the attraction between oxygen and hydrogen is called hydrogen bonding .
The orientation of hydrogen and oxygen molecules from dipole -dipole interactions of hydrogen bonding makes the oxygen and hydrogen atoms in ice to be pushed apart well spaced out in ice, making them less dense than liquid water where they were aggregated. Thus from the question option C is correct.
Answer:
The answer is: They filter microscopic organisms from the waters.
Explanation:
Barnacles are filter feeders, which is why they are usually on dock poles and non-moving structures underwater. They do not need to travel to get food, because it comes to them!
Homoeostasis is a system of maintaining balance. This is important because too much salt and the body can develop problems like high blood pressure, and edema. This increases the risk of a heart attack, strokes, dementia, and kidney disease. Then the dissolved carbon is unnecessary to the body.
Answer:
Explanation:
Domain. A domain is the most inclusive of the levels (meaning it has the most number of individuals in the group).
