Question 1: Sex hormones are a protein biomolecule.
Question 2: Triglycerides are: lipids that contain 3 fatty (oil) acids, while being hydrophilic.
Question 3: Carbon, Hydrogen, Oxygen, Phosphorus, Nitrogen, Sulfur. (think about CHOPPED NUTS)
Question 4: Photosynthesis is the process of solar energy turning into chemical energy, and light energy converting into water. We also discuss several other topics like jhu chemistry
Question 5: The two reactions are dehydration which the loss of water from the reacting molecule, and hydrolysis which water is breaking down compounds.
Question 6: The three domains are Bacteria, Archaea, and Eukarya. Question 7: Yes humans are organized.
Question 8: The basic units of life are cells.
Question 9: The organic molecules are Nucleic Acids, Proteins, Carbohydrates, and Lipids.
Question 10: Uracil is the base that replaces DNA for RNA, and adenine and uracil pair up to match DNA and RNA together.
Question 11: Adenine, Cytosine, Uracil, Thymine, and Guanine all make up DNA and RNA. If you want to learn more check out unlv biol 304
Question 12: The formula for Glucose is C6H12O6
Question 13: The similarities of DNA and RNA is that they both are made up of monomers that are called nucleotides, and they both have 3 bases: adenine, cytosine, and guanine.
Question 14: Biosphere is the land/ water where organisms exist, or all the regions on Earth.
Question 15: Ecosystem is a community or the actual environment organisms live in.
Question 16: Community is the whole population in one spot.
Question 17: A group of organisms of the same species is a population. Question 18: They are also called functional groups or the “R” Groups.
Question 19: Phospholipids, glycolipids, proteins, and cholesterol all make up the cell membrane.
Question 20: The four organic molecules are carbohydrates which are a good source of energy that have long chains of sugar. Protein which are amino acids grouped together. Lipids which are fatty acids and the building blocks of the biological membrane that stores energy, and nucleic acids which are organic compounds with heterocyclic rings.
Question 21: Passive transport is the movement of crossing the cell membrane without energy. If you want to learn more check out uttyler email login
Question 22: the movement of energy is active transport.
Question 23: Genes.
Question 24: Hydrophilic is water loving while hydrophobic hates water (non polar)
Question 25: Extinction is the death of the last species.
Question 26: Natural selection was brought upon by Darwin’s theory, where organisms who adapt better survive longer and pass them down to their offsprings.
Question 27: Coccus (spherical/oval), bacillus (rodlike), and Spiral are the three shapes of bacteria.
Question 28: The storage form for plants is starch, and the storage form for animals is Glycogen.
Question 29: Atom, molecule, cell, tissues, organ, organ system, organisms, population, community, ecosystem, biosphere.
Question 30: Organic chemistry is the study of structure, properties, and reactions of organic materials.
Question 31: The pH scale explains how acidic or basic something is on a scale of 114. 16 being acidic, 7 being neutral, and 814 being basic.
Question 32: A controlled group isn’t exposed to the independent variable, while the variable is.
Question 33: Bacteria: E. Coli, and found anywhere. Archaea: absorbs or chemosynthesis food, unicell., and similar to Eukarya. Eukarya: has a membrane/ nucleus. We also discuss several other topics like pols 2306 unit 3
Don't forget about the age old question of posc 362 textbook notes
Question 34: Hypothesis is something that can be tested, while a theory is already confirmed.
