Question

1. discuss three distinguishing characteristics that organisms in the animal kingdom share.

Explanation:

To discuss the three distinguishing characteristics of organisms in the animal kingdom (assuming the typo "anlmal" is "animal"): 1. Heterotrophic Nutrition: Animals cannot produce their own food (unlike plants which are autotrophic) and rely on consuming other organisms (either plants, animals, or organic matter) for energy. For example, a lion hunts and eats other animals, while a deer grazes on plants. 2. Multicellularity and Eukaryotic Cells: All animals are multicellular (composed of many cells) and their cells are eukaryotic, meaning they have a true nucleus and membrane - bound organelles. For instance, human cells have a nucleus that contains genetic material, and cells like muscle cells work together in a multicellular system. 3. Lack of Cell Walls: Unlike plants (which have cell walls made of cellulose) and fungi (which have cell walls made of chitin), animal cells do not have a cell wall. This allows for more flexibility in cell shape and movement, which is important for activities like muscle contraction in animals for movement or the changing shape of white blood cells as they move through tissues.

Answer:

1. Heterotrophic Nutrition: Animals consume other organisms for energy as they can't produce their own food.
2. Multicellularity and Eukaryotic Cells: Animals are multicellular, with cells having a true nucleus and membrane - bound organelles.
3. Lack of Cell Walls: Animal cells do not have a cell wall, enabling flexibility in cell shape and movement.
