I learned that the phylum Annelids can consist of many creatures such as earthworms, leeches, and scale worms can adapt to a variety of environments. Annelids’ bodies are divided into segments which are seen as rings by the naked eye. They have muscles which help them move by contracting their longitudinal and circular muscles. When Annelids take in food, the food particles travel through one end of the body and are excreted out the other side. The video enhanced my understanding about Annelids because without seeing different species and what classified them as Annelids I would have never known an earthworm or a leech fell into that phylum.
1) What are the muscles that Annelids use to move?
a. Longitudinal and circular muscles
b. Pectorals and obliques
c. Latitudinal and longitudinal muscles
d. None of the above
Answer: A, Longitudinal and circular muscles
2) Which of the following is an evolutionary improvement in annelids
c. Deuterstome development
d. Protostome development
Answer: B, Segmentation
In the phylum Mollusca, there are many organisms that have body parts that change as the environment around them change; such as the octopus. An octopus can camouflage to variety of objects in its environment. Each organism in the Mollusca phylum has a type of foot that stows mobility and they eat by a radula. The radula is strap like tongue that has very sharp teeth and they can change to be different shapes or sizes based on their prey. They have a pseudo coelomate body plan, meaning that they have a coelom that exists, but it is lined by mesoderm only on the body wall, not around the gut. This video enhanced my understanding standing of the phylum Mollu...

...nted muscles. The quadrupling of genes led to bigger animals such as elephants. The largest member of the chordate phylum that ever walked on Earth was dinosaurs. The closest animal relative to humans is great apes. Great apes can think, feel, nurture own kind, pass on social skills, mimic, and remember just like humans do. Human intelligence is greater than anything on Earth! This video enhanced my understanding on Chordates because it explains how some chordates are or are not vertebras and it showed how land animals evolved from fish. I always like to see different videos on how species originated, especially humans.
1) Which structure is present in a chordate?
b. Spinal cord
Answer: A, notochord.
2) Which of the following are not found in the phylum chordate?
Answer: D, Scorpions

- There is no doubt that arthropods are an extremely successful group of animals, with an estimated 5-10 million species worldwide, and this can be attributed to having an exoskeleton; it provides many benefits, such as protection from parasitism and other threats. However, one major disadvantage of having an exoskeleton is the limitations that an inelastic cuticle can place on growth. The exoskeleton provides protection, but when freshly moulted the animal is soft and vulnerable, as well as having limited mobility and use of appendages; many seek shelter before moulting....

- Helminthes or parasites, often called “worms” are among the most prevalence of chronic human infections worldwide. Soil-transmitted infections are caused by different species of parasitic worms. There are over 340 species of helminthes; most are rare in humans but may infect animals that can serve as a reservoir for infection but there are four main nematodes species of human soil-transmitted helminthes infections. Ascaris lumbricoides (round worm), trichuris trichura (whipworm), Ancylostoma duodenale and Necator americanus (hookworm).... [tags: Soil, Disease, Hygiene]

- 1. I believe that these polymers, Cellulose, starch and glycogen have different properties because they are used in different organisms. Cellulose and starch are mainly used in plants and glycogen is used in animals. Cellulose is used for strength in its stems and leaves and uses starch for help with storing things. Glycogen is used in animals to help store things as well. These polymers have different properties because they have different functions in different organisms. 2. Diffusion is the spreading out of particles from an area of high concentration to an area of low concentration.... [tags: Cellulose, Difussion, ATP]

- A. Arthropods inherited many great synapomorphies and unique functions such as an exoskeleton, molting and respiration. These traits that arthropods inherited have opened up many great opportunities in their evolution but they have also block some possibilities and cause some hardship. Firstly, molting and the exoskeleton of arthropods are like a double edged sword. The rigid exoskeleton that the arthropods possess provides protection. This exoskeleton is also the fundamental building materials for an array of tool like appendages.... [tags: biological analysis and characteristics]

- Evolutionary developmental biology (evo-devo) was instituted in the early 1980s as a distinctive field of study to characterise the new synthesis of evolution hypothesis (Müller, 2007). Evo-devo is regarded as a new rule in evolutionary biology and a complement to neo-Darwinian theories. It has formed from the combination of molecular developmental biology and evolutionary molecular genetics; their integration has helped greatly to understand both of these fields. Evo-devo as a discipline has been exploring the role of the process of individual development and the changes in evolutionary phenotype, meaning the developmental procedure by which single-celled zygotes grow to be multicellular or...

- Charles Darwin and Alfred Wallace's concept of natural selection and descent with modification helped shape the theory of evolution which holds as much weight as the theory of relativity per se. Evolutionary biology is the science devoted to understanding how populations change through time in response to modifications of their environment and how new species come into being by studying adaptation and diversity (Freeman and Herron 2004). Evolutionary biology has proved that all organisms have evolved from a common ancestor over the last 3.5 billion years.... [tags: Biology]

- Arthropoda Arthropods are animals belonging to the phylum Arthropoda, which is the largest of all phyla in the Animal Kingdom, with more than one million species, making them almost 80% of the whole kingdom. These include insects, arachnids, crustaceans and many more, most of which are quite small, the biggest being the Japanese Spider Crab with a leg span of 3.5 meters and the smallest being the microscopic Plankton. *Characteristics: - Segmented Body. - Exoskeleton.

- Biology is the science of living systems. It is inherently interdisciplinary, requiring knowledge of the physical sciences and mathematics, although specialities may be oriented toward a group of organisms or a level of organization. BOTANY is concerned with plant life, ZOOLOGY with animal life, algology with ALGAE, MYCOLOGY with fungi, MICROBIOLOGY with microorganisms such as protozoa and bacteria, CYTOLOGY with CELLS, and so on. All biological specialties, however, are concerned with life and its characteristics.... [tags: Biology]

- Biology 1. The virus is made up of five parts and is in the size range of 10 nm-300 nm in diameter. The first is the coat made up of protein that protects the virus to a point. Next is the head that contains the genetic material for the virus. The genetic material for a virus is DNA. The two other parts are the tail sheath and the tail fibers that are used for odd jobs. I believe that a virus is not considered to be a living creature due to the fact it is a parasitic reproducer. To me it is just like ripping up a piece of paper because it is still the same thing and it isn't carrying out any other function besides reproduction.... [tags: essays research papers]
