You have discovered a previously unknown organism. it is multicellular, with a filamentous form, and absorbs food from its environment. upon microscopic examination, you see that the cells have nuclei. how would you classify this organism?

This organism belongs to the kingdom Fungi.

Explanation:

Kingdom fungi include heterotrophic organisms. Their bodies are made up of hyphae which are the thread-like structures. Many hyphae together form an entangled mass called mycelium. Fungi are eukaryotes as they have a well-defined membrane-bound nucleus in their cells. Fungi absorb food from their surroundings with the help of their hyphae. Fungal cells have cell walls around their plasma membrane.

They are mostly multicellular; however, yeast is unicellular. Chitin is the major component of their cell walls. Since the observed organism is a multicellular and eukaryotic organism that derives nutrition from the surroundings and have a filamentous structure, it belongs to the kingdom fungi.

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products

brain development. a child's brain undergoes an amazing period of development from birth to three—producing more than a million neural connections each second. the development of the brain is influenced by many factors, including a child's relationships, experiences and environment.
