<span>The
mass of an atom comes from the protons and neutrons that are found in the
nucleus. The number of protons is the atomic number of an element. To find the
number of neutrons, subtract the atomic number from the mass of an atom. So the number of neutrons are 20 (mass number) - 5 (atomic number) = 15 neutrons.</span>

Answer:
The correct answer is - c. Larger claws would help the crab crack open the shells of the mussels so the crab can eat them.
Explanation:

Explanation:
Renewable resources are those which can be replaced naturally and repeatedly. For example, water, oxygen, and plants are examples of renewable resources.
Wood is a renewable resource as it is a part of trees. Trees are able to be replanted and can be cut down again, once they reach maturity. Plastics, glass, and steel are known as non-renewable resources as they cannot be replaced at a sufficient rate and usually have a limited supply. For example, plastics are created using a variety of different substances such as natural gas and oil (polyethylene). The Earth contains a limited supply of both substances, so plastic is deemed as being non-renewable.
As a result, the only renewable product in the choices provided above is a wooden spoon.
