A collection of simula cells tht preform particular function are?

i think it is true in my reasonment ..

spiders belong to a group of arachnids.

arachnids have the following traits :

they have two body parts.

they have eight legs unlike insects which have 6 legs.

they have no wings.

these traits distinguish them from insects.

the information that antonio is doubting us the statement that spiders differences are as a result of being first to evolve.

this is because the evolution of one species is independent of the other species.

some inherited genetic mutations can be good for the offspring, so the answer is different genetic mutations cause many forms of cancer.
