Answer 1

Answer:

- Most animals have the capacity for active movement

- Animal zygotes undergo mitotic divisions called cleavage

- All animals are heterotrophs

Explanation:

Animals, also known as metazoans, are multicellular eukaryotic organisms from the kingdom Animalia. Animals are a monophyletic group, i.e., all animals are derived from a common ancestor. Animals can be classified into two main groups: 1- invertebrates that don't have a backbone inside their body (e.g., earthworms, octopus, snails, insects, etc) and 2-vertebrates that have a backbone inside their body (e.g., fish, amphibians, reptiles, birds, mammals). Cleavage refers to the division of animal cells in the early embryo. In animals, the zygotic cell divides by mitosis (i.e., cleavage), into smaller cells called blastomeres. Some of the most common characteristics of the animal kingdom are:

- heterotrophy: animals cannot produce their own food and obtain energy by feeding organic material present in other organisms

- generally reproduce through sexual reproduction

- animal's cells do not have cell walls

- they are able to move in almost one stage of their lives

- they can respond to external stimuli by nerve cells and/or muscle cells
