H

• Homeostasis


  Keeping things the same or an internal balance
• Homeostasis


  • Temperature
• Cell membrane


  Composed of mainly lipids and proteins
• Amino acids


  Have a nitrogen unit
• Bacteria cells divide


  Asexually by binary fission
• withered plants

  Have lost water resulting in low turgor pressure.
• Helicase


  Enzyme that unzips the DNA molecule
• DNA polymerase


  Enzyme that adds nitrogen bases/nucleotides
• Enzymes


  Catalysts that speed up or slow down chemical reactions
• Mitochondria


  Powerhouse of the cell because Aerobic cell respiration occurs inside of it in the ETC
• Anaerobic respiration


  Occurs in the cytoplasm of the cell
• Glucose


  Simple carbohydrate made in the chloroplast
• Photosynthesis


  Makes glucose and oxygen
• Vacuoles


  Store water and waste
• Ribosomes


  Site for protein synthesis
• Rough ER


  Has ribosomes attached
• Golgi apparatus/bodies


  Package the proteins
• Lysosomes


  Have digestive enzymes that digest worn out cellular parts
• Cells


  • Fungi, plants, and bacteria have cell walls
  • Animal cells do not have cell walls
• Interphase


  Has a g1, s, and g2 stage. It is where the cell grows twice, duplicates organelles and replicates the DNA strand
• Telophase


  Produces 2 new identical daughter cells
• Meiosis


  Produces 4 haploid sex gamete cells with half the number of chromosomes
• Phenotype


  Your physical makeup you can see
• Genotype


  The inherited genes that come in pairs
• Homologous Structures


  Have similar structure but different function
• Amoebas


  Asymmetrical-No definite shape
• Passive transport


  Such as osmosis, diffusion, and facilitated diffusion does not use cellular energy
• ATP


  Cellular energy know as Adenosine Tri Phosphate
• DNA


  Has the bases Adenine paired with Thymine. And Guanine paired with cytosine
• RNA


  Has the bases A, Uracil, G and C. It has no thymine
• DNA


  Cannot leave the nucleus but RNA can go through the cytoplasm to the ribosome
• RNA types


  • tRNA transfers Amino acids
  • rRNA is ribosomal RNA site for protein making
  • mRNA is messenger RNA with transcribed information from DNA
• Science is a search for evidence in order to answer questions or problems
• Since solutions to problems can have more than one answer, we make observations, collect data and ask questions so we can investigate answers or possible solutions
• In order to choose one solution over another

  1. Research information from many sources

  2. Eliminate research that uses data that cannot be verified or supported by evidence

  3. Be able to recognize if data is biased

  4. Eliminate data that has a set idea of the outcome before it is tested
• The steps in logically solving problems are often called the scientific method
• Hypothesis


  An "educated prediction" based on prior knowledge and research, which cannot be proven correct without being tested
• Dependent variable


  • The variable that is measured in the experiment (the height of the pea plants)
• Independent variable


  • The factor that is changed in an experiment (growth hormone)
• Steps of the Scientific Method

  1. Problem-identify the problem or ask a question

  2. Research the problem-check books, scientific papers, and other sources for information

  3. Form a hypothesis-state how the independent variable will affect the dependent variable

  4. Create an experimental design to test your hypothesis

  5. Identify experimental controls- unchanging factors

  6. Data-Observe and record results with charts, lists, graphs, etc.

  7. Analyze to predict trends and examine data to see if data supports the hypothesis

  8. Draw a conclusion based on the results of your data
