Starfish are classified under the domain Eukarya. Their multicellular presence and existing nuclei exclude them from prokaryotic domains. Furthermore, they are classified in the Animalia kingdom because they are not prokaryotes or protists. Next, Sea Stars fall under echinoderms, which are invertebrates characterized by their hard, spiny skin. The echinoderm phylum consists of mostly sea creatures (Pawson & Miller, 2016). Organisms placed in the Asteroidea class are identified by their arms that…

This paper will refer to the domain of Archaea. The archaea are single-celled prokaryotes that were classified in the bacteria domain naming them the Archaeabacteria. Until just recently the scientific community decided that these special creatures belonged in their very own domain. The archaea resembled the eukaryotes more than the bacteria even though they were still a prokaryotic organism. So these micro-organisms had to be moved into its own domain. These organisms are what many…

Riley 1 Why is Evolution so important? Some might ask this because of the confusion drawn over the topic. However it is one of the most intriguing scientific theories that exists today. Evolution is far more interesting than the Theory of Gravity, or Germ Theory. This one addressed many age old questions, such as what is our place in this world, and where did we come from. Some might not accept it because it may conflict with their religion, especially in America, where only 60% of all Americans…

The purpose of the immune system is to defend the body against any foreign invaders that might do the body harm by using a series of immune responses to prevent the entry or survival of any foreign body. The human immune system uses three types of responses: barriers, nonspecific defenses, and specific defenses. Barriers and nonspecific defenses are innate or rather they are the defenses humans are born with while specific defenses are acquired throughout our lifetime. The immune system is also…

Animals are eukaryotic and multicellular,[5][6] which separates them from prokaryotic bacteria and eukaryotic but unicellular protists. Unlike plants and algae, which produce their own nutrients (and, with fungi, have rigid cell walls),[7] animals are heterotrophic,[6][8] consuming organic material and digesting it internally.[9] With very few exceptions, animals breathe oxygen…

I. The most basic unit of life is the cell. All living things are composed of cells. Cells may only from through a process of division and replication of previously existing cells. Cells are microscopic; however their structure is complex. All types of cells possess a plasma membrane which separates its contents from its surroundings. . There are two types of cells: prokaryotic and eukaryotic. a. Prokaryotic cells are simpler than eukaryotic cells. Within prokaryotic cells are bacteria cells…

Most would think no lifeforms could survive in such depths with the extreme temperatures, darkness, and immense water pressure, but they do. Over four hundred types of foraminifera, which are single-celled protists, have been found here as well as amphipods, worms, sea cucumbers, and shrimp. Along with this, a record was set for the deepest depth of a found fish. It is an unknown species of snailfish. Not only is the living of importance here, but the physical…

From a biological point of view, humans are not plants, fungi, protists, or monera; humans are animals. Believing ourselves to be the pinnacle of creation, the smartest and most capable of all that populate this planet, we face a conundrum that we fall in the same classification with earthworms, flounder, bulldogs, and orangutans. Clifford Geertz, an anthropologist, explained this by asserting “Man is an animal suspended in webs of significance he himself has spun” (Clifford 5). Those “webs…

The Animal Book Chapter 1: Animal characteristics Chapter 2: Body Parts Body plans refer to similarities in development, structure, and function among members of a particular group (phylum). At some point, members of that group share the same body plan during their development process. Which could be a possible explanation for shared structural plans that have been observed in the anatomy and embryology. Timing, pattern, and scale of development determine the organism's shape, and closely…
