Correct matching of invertebrates and its characteristics are as follows:
Sponges are animals which have many cell but no mouth, muscles , heart or brain. They are sessile and can not move from place to place like other animals do, filter feeding animals with an asymmetrical body plan.
Cnidarians are the animals with radial symmetry and stinging cnidocyte cells. These animals consists a special cell cnida which functions in preying catch and defense. example- jellyfish, anemone.
Flatworms are the worm like animal which do not consist a body cavity or coelom. example- fluke and tapeworms.
Roundworms or threadworms are segmented worms that can live in water or land. They consist a body cavity and internal organs. examples- pinworms and hookworms.
Mollusks are the animals which consist mentle, foot and and sometimes a shell. example- octopus, squids.
Echinoderms are the animals which have radial symmetry and an endoskeleton made out of calcareous plate. These animals live only in marine environment.These animals lack circulatory and excretory systems.
Arthopods are the animals with jointed legs and an exoskeleton made out of chitin. example- spiders, shrimps and crabs.
There are many steps for that and here I'm going to explain it to you. The first step is that a cell copies the genetic instructions and then the dna unrolls. The second step is that RNA polymerase binds onto the strand. Then the third step is that the messenger RNA is ordered to go out of the nucleus into the cytoplasm to a ribosome. ANd the final step is the the ribosomes <span>then take the mRNA and translate it into amino acids. That is how it is translated</span>
The active site is <span> a site on the substrate molecule where specific enzyme molecules bind.</span>
A trait is the organism's feature. So, a trait would be eye color. A phenotype would be hazel. An allele is a gene. It can be recessive or dominant.
