to maintain proper metabolism, mainly gas exchange
No, muticellular.
A sea star is multicellular.
multicellular, all animals are

Ventilation systems in multicellular organisms are important for the exchange of gases, such as oxygen and carbon dioxide, which are necessary for cellular respiration. These systems help ensure that oxygen is delivered to tissues and carbon dioxide is removed efficiently, supporting the metabolic needs of the organism.
Yes, frogs are multicellular organisms. They are made up of many cells that work together to form tissues, organs, and organ systems, allowing them to carry out various functions necessary for life.
because the animals have lots of pubes
The American alligator is multicellular. As a complex organism, it is composed of many cells that work together to form tissues, organs, and systems necessary for its survival. These multicellular structures allow for specialized functions, such as digestion, movement, and reproduction.
Plants use vascular tissues like xylem and phloem to transport water, nutrients, and sugars throughout their bodies. Animals have circulatory systems that use blood to carry oxygen, nutrients, and waste products around the body. Additionally, animals can actively move from one place to another, while plants are anchored in the ground and rely on passive means like wind or animals for seed dispersal.
No, not all multicellular organisms have skeletal systems. While many animals, such as vertebrates, possess internal or external skeletons for support and protection, other multicellular organisms, like jellyfish or sponges, lack a skeletal structure. Instead, they rely on other means, such as hydrostatic pressure or a soft body structure, for support and movement. In summary, skeletal systems are not a universal feature among multicellular organisms.
I think that animals, migrate depending on the weather, and if the food is scarce where they live, at least me I used to live in Mexico and the Monarch butterflies used to fly all the way from Canada to Mexico. I t was really amazing. Animals need necessitates as well as we do. We are animals believe it or not.
