Period 10 Questions and Answers

2. PHYLA IN THE ANIMAL KINGDOM
PORIFERA- no symmetry, sponges
CNIDARIA- radial symmetry, jellyfish
PLATYHELMINTHES- flat worms, planarian
NEMATODA- roundworms, Pinworm
ANNELIDA- segmented worms, earthworm
MOLLUSCA- soft bodies, often have a shell
ECHINODERMATA- tube feet, sea star
ARTHROPODA- “jointed feet,” exoskeleton, insects
CHORDATA- notochord, dorsal nerve cord, gill slits

3. Science through Inquiry
Problem, Information, Hypothesis, Experiment, Data, Conclusions are the steps of the scientific method.
Lab tools are: Forceps, Beaker, Scissors, Dissecting Tray, Pointer, Erlenmeyer flask, Graduated Cylinder
The Lab Drawing Rules are: include lines to the right, no arrows, no underlining, you must label all parts.

4. Cell Theory and Cell Processes
Cell  Tissue  Organ  Organ System
Eukaryotic cells HAVE A NUCLEUS. Prokaryotic cells DO NOT HAVE A NUCLEUS.
Photosynthesis:
6CO2 + 6H2O  C6H12O6 + 6O2
Respiration:
C6H12O6 + 6O2  6CO2 + 6H2O

5. Genetics
7. Cells are the basic units of life. 8. A genetic disorder is an abnormal condition that a person inherits through genes or chromosomes. 9. A diagram that shows the possible genotypes of an offspring between two parents is a PUNNETT SQUARE.

6. Punnett Square Example

7. Evolution and Natural Selection
Evolution is gradual changes over time.
Charles Darwin developed the Theory of Evolution.
Natural selection is when the best adapted organisms survive and reproduce. The color of the peppered moth helping it to survive in its environment is an example of natural selection.

8. Classification
13. A scientific name is written with the Genus capitalized, species lowercase, and both words underlined (Genus species) 14. Cells  Tissues  Organs  Organ systems 15. Binomial nomenclature is the naming system developed by Linnaeus.

9. Simple Organisms
16. A virus is a nonliving particle that enters and reproduces inside a living cell. 17. Algae are plant like protists. 18. Spores are tiny cells that are able to grow into a new organism. Fungi use these to reproduce.

10. Plant Kingdom Seedless plants use SPORES to reproduce.
Plants are EUKARYOTES because their cells have a nucleus.
Vascular plants have vascular tissue, which helps transport materials throughout the plant.

11. Animal Kingdom
22. Phyla in the animal kingdom are: PORIFERA, CNIDARIA, PLATYHELMINTHES, NEMATODA, ANNELIDA, MOLLUSCA, ECHINODERMATA, ARTHROPODA, CHORDATA 23. Phylum Chordata includes animals that: had gills slits at some point in their lives, have a dorsal nerve cord, and a notochord. 24. The largest population that an area can support is the CARRYING CAPACITY.
