Complete question:
Which correctly describes the set of clades that contain the arthropods, from largest to smallest?
- Archaea: Eukaryotes: Opisthokonts: Animals: Protostomes Ecdysozoa: Arthropods
- Eukaryotes: Opisthokonts: Nuclearia: Animals: Protostomes Ecdysozoa: Arthropods
- Eukaryotes: Opisthokonts: Animals: Deuterostomes Ecdysozoa: Arthropods
- Eukaryotes: Opisthokonts: Animals: Protostomes: Ecdysozoa: Arthropods
Answer:
4. Eukaryotes: Opisthokonts: Animals: Protostomes: Ecdysozoa: Arthropods
Explanation:
Taxonomy is the study of different organisms, their classification into categories according to their morphological and molecular characteristics and their evolutionary relationships, and assigning to each them a binomial name.
- The eukarya domain is composed of all the unicellular or pluricellular organisms that have eukaryotic cells that characterize by having a well-defined nucleus surrounded by a complex biological membrane. They also present organelles delimitated by membranes. These organisms reproduce asexually and sexually.
- Animalia Kingdom: Includes different phyla closely relates.
- The embryonary development of bilateral coelom animals makes a place for the division of two groups: protostomes and deuterostomes. Among protostomes might be mentioned the flatworms, annelids, mollusks, and arthropods. Protostomes show spiral initial segmentation, and the mouth develops as a first opening near the blastopore.
- Ecdysozoan Superphylum: Their bodies are covered by a cuticle that provides protection. They have a complete digestive system. They might reproduce sexually and asexually.
- Phylum Arthropoda: Invertebrates characterized for having an exoskeleton, a segmented body, and articulated appendixes. A very diverse group with many different characteristics.
The whiff of the perfume of Tammy reached the nostrils of Jim through the process of diffusion. The process of diffusion can be defined as the process by which the substances (liquid and gases) move from one place to another from the area of high concentration to the area of lower concentration. The particles of the perfume move from the Tammy's body (high concentration) towards Jim through the air (low concentration).
Hence, the answer is 'Option B - diffusion'.
Answer:
Why would a plant cell have a chloroplast while an animal cell wouldn't? Chloroplasts are used to make food through photosynthesis. Plant cells make their own food, while animals do not.
