Answer:
unicellular means one cell, and multicellular is multiple cells. just look at the prefixes and suffixes and the answer will be obviously apparent
if you do this and still don't know the answer, then learn the definition of a multicellular organism.
<span>ecosystems
</span>An ecosystem involves both the biological (plants, animals, human beings) and non-biological (land, water, soil, and atmosphere) community which interacts as a system. More importantly, the living things are very dependent on the abiotic community since it cannot survive by itself. Every animal, plant and human needs the primary physiological needs of water, food and shelter provided by the abiotic system. <span> </span>
Answer:
ALGAE
…walls of many seaweeds contain phycocolloids (algal colloids) that can be extracted by hot water. The three major phycocolloids are alginates, agars, and carrageenans. Alginates are extracted primarily from brown seaweeds, and agar and carrageenan are extracted from red seaweeds. These phycocolloids are polymers of chemically modified sugar molecules, such…

The most important step to take in the case of the scenario given in the question is to assess and establish adequate ventilation. Deprivation of oxygen causes the heart rate to drop because the heart is not getting enough oxygen, and the single most important and effective thing to do in this situation is to ventilate the lungs of the baby.
Compared to cnidarians, bilaterally symmetrical animals have a central nervous system.
<h3>What do bilaterally symmetrical animals have?</h3>
• Bilaterally symmetrical animals have "heads" and "tails" (front and back), front and rear (back and abdomen), and left and right sides. All true animals are bilaterally symmetrical, except those with radial symmetry. The
• longitudinal nerve cords, usually in 3-5 pairs, extend posteriorly from the brain. They are connected by transverse commissures, with smaller lateral nerves extending from the cords. The peripheral plexus arises from the lateral nerve.
<h3>Do bilaterally symmetrical animals have diffuse neural networks?</h3>
Neural networks consist of interconnected neurons that lack brains or some form of cephalization. Organisms with bilateral symmetry are usually associated with neuronal compression and, in a more advanced form, with the central nervous system, whereas organisms with radial symmetry are associated with neural networks.
