What clade includes all animals that have true tissues and body symmetry?Multiple choice question.DeuterostomiaEumetazoaProtostomiaBilateria

Break Down the Problem

1. Identify the characteristics mentioned in the question: true tissues and body symmetry.
2. Analyze the provided options to determine which clade encompasses these characteristics.

Relevant Concepts

• True Tissues: Refers to organized groups of cells that work together to perform specific functions.
• Body Symmetry: Can be bilateral, radial, or asymmetrical; however, true body symmetry is generally bilateral in the context of higher animals.

Analysis and Detail

• Deuterostomia: A clade that is characterized by their embryonic development, including specific formations, but it doesn’t specifically include all animals with true tissues and body symmetry.
• Eumetazoa: This clade includes all animals (metazoans) that have true tissues. It includes both radially and bilaterally symmetrical animals.
• Protostomia: While this clade includes many animals with true tissues, it is not inclusive of all animals as it excludes deuterostomes.
• Bilateria: Refers specifically to animals that exhibit bilateral symmetry, but does not encompass all animals with true tissues, such as some radially symmetrical organisms.

Verify and Summarize

Based on the definitions and characteristics, Eumetazoa is the clade that specifically includes all animals with true tissues and a variety of body symmetry types, including both radial and bilateral.

Final Answer

Eumetazoa is the correct answer, as it includes all animals that have true tissues and body symmetry.
