Humans and apes have five fingers they can use to grasp objects. Do you think these are analogous or homologous structures

1 answer:

6 0

Human and apes have 5 fingers that are used for grasping objects, so they have the same function, but they also have a common ancestor and are closely related, that means that this is an example of homologous structures. In evolutionary biology, the term homologous structures means that there are organs and skeletal elements of animals and organisms, that by virtue of their similarity, suggest their connection to a common ancestor.

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.

Irina18 [472]

A CNA, certified nursing assistant, can administer medication to patients. BUT this duty is subject to the level of experience and training of the CNA as well as the regulation of the state.

CNAs basically assist in the day-to-day care of patients like:
1) bathe and dressing
2) serving meals and helping them eat
3) taking their vital signs
4) and other basic necessities to ensure that the patient is comfortable and well cared for.
