Because they lack well-defined and complex organ systems, we hypothesize that _____ diverged from all other animals early in the

astraxan [27]

Answer:

Poriferans.

Explanation:

The evolution of the organisms has been occur from the simple organisms and leads to the evolution of the more complex organisms. This complexity arises due to the changing environment of the organisms.

The protozoans are the simplest organisms and all the other animal lineage has been derived from the porifera. The porifera are the cellular organisms that do not have tissue level of organization and simple physiological system. Later, diverse and complex organisms arise from the porifera.

Thus, the correct answer is option (1).

2. Lipids (dont form polymers): Components: glycerol, fatty acid, components of a fat molecule Functions: energy storage, cell membrane components, and hormones Ex: fats, phospholipids, and steroids

3. Proteins:

Components: amino group, carboxil group, R group, and amino acid Function: enzyme, structural protein, movement, transport, communication, defense, storage, receive signals Ex: lactose, hair, tendons, muscles, hemoglobin, signal proteins, antibodies, egg albumin, receptor protein

4. Nucleic acids:

Components: phosphate group, nitrogeneous base, ribose or deoxyribose, nucleotide Functions: heredity, DNA

Ex: code for proteins, DNA and RNA
