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:
No. Gender traits in humans are largely determined by biophysical processes.
Explanation:
There seems to be a vocal political faction that is trying to convince people in the name of liberty and equality that gender traits are completely learned, and therefore arbitrary. But this claim disagrees with scientific evidence. In general, boys play more with cars and girls play more with dolls not because their parents are perpetuating outdated gender stereotypes, but because their brain is telling them to. This fact does not mean that boys have to play with boy toys, or that boys who play with dolls aren't really boys. It is just a scientific observation about average behavior and its link to fetal development.
Answer:
sensory (afferent ) neurons
Explanation:
afferent or "sensory" neurons receive information from the external world and convey this information to the brain via the spinal cord .
Antimicrobial drugs are of limited usefulness because MOST STRAIN OF B. ANTHRACIS ARE RESISTANT TO A WIDE VARIETY OF ANTIMICROBIAL DRUGS. Bacillus anthracis is gram positive bacteria which exists in two forms; vegetable and spores form. It is an agent of bio-warfare because of its ability to kill quickly.
