neutrons and protons electrons are on the outer shell
Within the shell is a pair of "arms," often long and spirally coiled, bearing rows of ciliated tentacles by which a current of water is made to flow into the mantle cavity, bringing the microscopic food to the mouth between the bases of the arms. The shell is both opened and closed by special muscles. They form two orders; Lyopoma, in which the shell is thin, and without a distinct hinge, as in Lingula; and Arthropoma, in which the firm calcareous shell has a regular hinge, as in Rhynchonella.
Similar for they have the same number of electrons in the last shell
Embryo = Life - germ Outer coat = Shell Endrosperm = Meat
number of electrons in valence (last) shell
A butterfly is made of three parts, the head, thorax, and abdomen. It also has six legs and two wings.
Grasshoppers do not have a hard shell.
There is only one situation when a butterfly has a coiled shell. This is when the butterfly has died and its internals are dried up. The shell then covers the dead insides.
If you take a rope and coil it up on a flat table, you will get the basic idea of what a coiled shell looks like. Or, you could look at a cinnamon roll which is the culinary equivalent of a coiled shell. I'm going to let you decide....does a lobster look like a cinnamon roll?
Did you mean "Nautiloid?" Which is a sea creature similar to a Nautilis, only its shell it cone shaped instead of coiled. It also died out a long time ago.
Grasshoppers, like other insects, maintain stable internal conditions through homeostasis. The exoskeleton is a hard outer shell that helps protect their bodies and internal parts.
False
Nautilus
The answer is octopus.
True
Grasshoppers have a hard 'shell' (which is their exoskeleton), a skeleton worn on the outside of the body to protect soft tissues, rather than an endoskeleton (like what humans have) which is a support framework mostly located within the tissues.
Discoscaphites iris is a fossil of a cephalopod mollusk. It is a coiled shell that looks much like a nautilus seashell.
