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.
Answer:
The dispersion pattern of the population depends on the type of the population and their distribution in the environment. Different types of dispersion are uniform, random and clumped.
The uniform dispersion occur when the population is evenly spaced out in the area. Random dispersion is independent of the other individuals and randomly spaced. Clumped dispersion is greatly influenced by the behavior and the resources. Population are present in small patches.
The Pancreas is a glandular organ in the upper abdomen, but really it serves as two glands in one: a digestive exocrine gland and a hormone-producing endocrine gland. Functioning as an exocrine gland, the Pancreas excretes enzymes to break down the proteins, lipids, carbonhydrates, and nucleic acids in food.
