Pre-lab questions: 1. Algae belong to what Kingdom? They belong to the Kingdom Protista. 2. What are the three types of multicellular algae? The three types if multicellular algae are chlorophyta which are green algae‚ phaeophyta which are brown algae‚ and rhodophyta which are red algae. 3. Are algae autotrophs or heterotrophs? Algae are autotrophs. 4. What organelle allows plants (and plantlike protists) to photosynthesize? The chloroplasts allow plants and plantlike protists to photosynthesize

Procedure: Before starting the experiment I gathered all materials appropriate for the experiment and prepare a safe environment for my experiment. I record the boiling point of the Isopropyl Alcohol and the melting point of powdered Acetamide with lab equipment such as the thermometer‚ capillary tube‚ beaker‚ test tube‚ and burner fuel. Data Tables/Observations: Boiling Point of Isopropyl Alcohol | | | | Trial # | Boiling Point(°C) | Percent Error % | Observations | Trial 1 | 82.5°C

need for it to be retained in the plant. This means that guard cells on the stomata are generally inactive. 3. An increased number of stomata‚ that can be on either side of leaves. 4. A less rigid structure: water pressure supports them. 5. Flat leaves on surface plants for floatation. 6. Air sacs for floatation. 7. Smaller roots: water can diffuse directly into leaves. 8. Feathery roots: no need to support

does not have an increase in percent transmittance. For Cuvette 2 (unboiled/dark)‚ from 0 to 5 minutes‚ it increased fast but then leveled off from 5 to 15 minutes. Cuvette 3 (unboiled/light)‚ it had a steady but fast increase for the entire amount of time‚ from 0 to 15 minutes. Cuvette 4 (boiled/light) it had a very slight increase from 0 to 5 minutes‚ but then mostly leveled off from 5 to 15 minutes. Cuvette 5 (no chloroplasts) actually had a very slight decrease in the transmittance‚ but for the most

site. 5. The Inhibitor is subsequently‚ removed. 6. The Transcription factor can now join to the DNA‚ initiating transcription (production of mRNA from DNA) SiRNA: 1. An enzymes cuts up a piece of double stranded mRNA. 2. This makes little double stranded fragements‚ called SiRNA. 3. One strand of the SiRNA binds with a enzyme. 4. The enzyme is brought to the mRNA‚ due to the free bases of the SiRNA binding to a complimentary region on the mRNA. 5. The enzyme

Paramecium living in the intestines of termites breaks down the cellulose walls of wood fibers releasing proteins that are absorbed by the termites’ digestive system. Paramecium benefit by having an environment to thrive and they ingest the wood fibers for their own nutrition as well. 2. c. An important ecological effect
