Biology 1409 Lab Exam 2
1. What are the three types of symmetry in biology?: Asymmetry, Bilateral,
and Radial
2. What is the difference between vertebrates and invertebrates?:
invertebrates lack a back bone.
3. What are the major Phyla in the animal kingdom?: Porifera, Cnidaria,
Platy- helimithes, Annelida, Arthropoda, Mollusca, Echinodermata, and
Chordata
4. What is Porifera?: Know as sponges. They have no true tissues and are
asym- metrical. They are known as filter feeders. And are hermaphrodites.
5. What is Cnidaria?: They have radial symmetry. Has true tissues. Has a wide
range of motile forms including hydras, corals, and jellies. They have a
cardiovascu- lar cavity. There are two variations on this body plan: The largely
sessile polyp and the more motile medusa.

  1. What is Platyhelimithes?: Bilateral, and hermaphrodites. Known as flatworms. Include a lot of parasitic species. They are don't have a body cavity and lack a circulatory system.
  2. What is Annelida?: Bilateral and reproduce sexually and asexually. They are segmented worms that live in the sea, freshwater, and damp soil.
  3. What is Arthropoda?: The most diverse. Reproduce sexually. They have a seg- mented body, a hard exoskeleton, and jointed appendages.
  4. What is Mollusca?: Most of them are hermaphrodites. Known as snails, slugs, oysters, clams, and octopuses and squids. They are the second most diverse and soft-bodied. While most have a hard protective shell made of calcium carbonate. They have 3 main parts: muscular foot, visceral mass, and a mantle.
  5. What is Echinodermata?: Radial Symmetry. Known as sea stars. They are slow moving marine animals. They have a thin epidermis covers an endoskeleton of hard calcareous plates. Which includes the water vascular

  1. Types of Bones?: Compact and Spongy
  2. Types of Muscles cells?: Skeletal, Smooth, and Cardiac
  3. Body/Organ systems?: Digestive, Circulatory , Respiratory, Immune, Excreto- ry, Endocrine, Reproductive, Nervous, Integumentary, Skeletal, and Muscular

  1. Sight Sensory System: Rods, Cones, and after image
  2. What are rods and what makes them significant?: are more sensitive to light but don't distinguish colors; enable us to see at night, but only in black and white.
  3. Cones?: provide color vision but being less sensitive, contribute very little night vision. 3 types: red,green, blue
  4. After image?:
  5. Anatomy of the eye?: overview, retina, photoreceptor cells, and visual pigments

  1. What is the circulatory system?: The blood circulatory system delivers nu- trients and oxygen to all cells in the body. It consists of the heart and the blood vessels running through the entire body. The arteries carry blood away from the heart; the veins carry it back to the heart. Has 3 basic components: circulatory fluid, and interconnecting vessels, and muscular pump, and the heart. Open or closed. Open= circulatory fluid= hemolymph. Closed= CF= blood.
  2. what is the respiratory system?: Carry out this exchange of gases as we breathe. ... During the process, the red blood cells collect the carbon dioxide and transport it back to the lungs, where it leaves the body when we exhale.
  3. What are the type of cells found in blood?: Leukocytes (white blood cells), Platelets, and Erythrocytes (red blood cells)
  4. Radial Symmetry: ex. sea anemone or flower pot. does not have left or

  1. Excretory System: Kidneys, ureters, urinary bladder, urethra Function: disposal of metabolic wastes
  2. Endocrine System: Pituitary, thyroid, pancreas, adrenal, other hormone- secret- ing glands Function: coordination of body activities

  1. Reproductive System: ovaries or testes, and associated organs Function: reproduction
  2. Nervous Systems: brainm spinal cord, nerves, sensory organs Function: coordination of body activities
  3. Integumentary System: skin and its derivatives Function: protection against injury, infection, dehyration
  4. Skeletal System: skeleton Function: body support, protection of internal organs, movement
  5. Muscular System: skeletal muscles Function: locomotion
  6. Sympathetic Division: corresponds to arousal and energy generation
  7. Parasympathetic Division: causes opposite responses that promote calming and a return to self-maintenance functions

  1. Mutualism: interspecific interaction that benefits both species.
  2. Commensalism: interaction between species that benefits one of the species but neither harms or helps the other.
  3. Facilitation: can have positive effects on the survival and reproduction.
  4. Food Chain: transfer of food energy up the trophic levels from its source in plants autotrophs to consumers
  5. lithotrophs: organisms that can produce metabolically useful energy by processes that depend on the oxidation of inorganic compounds.

  1. Biomagnification: is the increasing concentration of a substance, such as a toxic chemical, in the tissues of organisms at successively higher levels in a food chain.
  2. Competition: the struggle between organisms to survive in a habitat with limited resources in the same place at the same time
  3. Predation: An interaction in which one organism kills and eats another.
