Answer:

(d) Nematoda.

Explanation:

Pseudocoelomate organisms are animals that possess a pseudocoelom (not a true coelom). A perfect example of animals that are pseudocoelomate are those that belong to the phylum Nematoda. They include roundworms, hookworms etc. A pseudocoelom is a cavity containing fluid which immerses the internal organs of a nematode.

Their physical structure is triploblastic and bilaterally symmetrical. They have two body openings that links to their digestive system, but do not possess a stomach.

Animals that belongs to phylum Arthropoda are coelomate organisms, meaning they possess.

Animals that belongs to phylum Cnidaria are acoelomate organisms, meaning they do not posses coelom.

Animals that belongs to phylum Porifera are acoelomate organisms.

How many nucleotide bases are there in 24 codons? Show work, circle final answer
JulsSmile [24]

Answer:

The nucleotide triplet that encodes an amino acid is called a codon. Each group of three nucleotides encodes one amino acid. Since there are 64 combinations of 4 nucleotides taken three at a time and only 20 amino acids, the code is degenerate (more than one codon per amino acid, in most cases).
