Answer:

Multicellular

Explanation:

Unicellular, as the prefix "uni" implies, only have ONE cell. Unicellular organisms can include bacteria, yeast, protists, etc. Multicellular organisms have many cells and are any plant or animal, as they are much larger and complex than unicellular organisms.

As for the second question, the frilled lizard is a perfect example of the ways that organs work together to form necessary organ systems. In the instance of the heart, there are cardiac muscle cells that branch and connect to each other to form cardiac muscle tissue, which has special junctions that cause the cells to contract together and in turn keep the heart pumping and the circulatory system moving.

Does this make sense? Feel free to comment any other questions!! If this explanation helped you, please consider leaving me a good review and/or brainliest!! <3
