Planaria - Study guides, Class notes & Summaries

3 Types pf animal skeletons - Hyrdostatic skeletons, exoskeletons, endoskeletons 5 general types of tastants - sweet, sour, bitter, salty, unami Actin - attach to the z-discs and project toward the middle of the sacromere Amplitude - height of a sound wave is correlated with the volume (loudness) of a sound Auditory nerve - signals from the vibration of the basilar membrane causing cilia hair cells to bend are sent to the brain. Burring or crawling - Must overcome great friction between th...

Meiosis lead to the production of ________. - Gametes Mitosis leads to the production of ________. - Somatic cells What are the functions of mitosis? - Growth, repair/replacement, and asexual reproduction in planaria. What is the G1 stage responsible for? - Cell growth, transcription/translation, duplication of organelles, and to prepare for DNA replication. What is the S phase of interphase responsible for? - DNA replication. It only occurs during this phase. What is the G2 phase of ...

why are planaria so extensively studied? - Answer because they are the most primitive biological group with neural features like brains of the 2 groups in the planaria study the group that was able to turn off the light by intercepting the electric eye - Answer passed the eye more than the other group demonstrating that they learned from consequences if a behavior is started and maintained (strengthened by becoming more likely or more intense) due to a consequence that consequence is c...
