◉ How do the cohesive and adhesive properties of water compare to
those of oil and alcohol?
Answer: Water has both stronger cohesive and adhesive properties.
◉ How would you explain the role of heat of evaporation in water's
unique properties compared to oil and alcohol?
Answer: Water has a moderate heat of evaporation compared to oil
and alcohol, allowing it to provide cooling without losing too much
volume.
◉ Why is the fact that water's solid form (ice) is less dense than its
liquid form important for aquatic ecosystems?
Answer: It allows ice to float on water, preventing the entire body of
water from freezing.
◉ examples include DNA and RNA
Answer: nucleic acids
◉ examples include enzymes, hemoglobin, keratin, and collagen
,Answer: proteins
◉ monomers are nucleotides
Answer: nucleic acids
◉ examples include triglycerides, steroids, and phospholipids
Answer: lipids
◉ examples include glucose, cellulose, and glycogen
Answer: carbohydrates
◉ Functions include signaling, regulation, structure, and movement.
Answer: proteins
◉ Building blocks are glycerol and fatty acids.
Answer: lipids
◉ monomers are amino acids
Answer: proteins
◉ Functions include membrane composition, long-term energy
storage, and insulation.
, Answer: lipids
◉ Function includes storage of genetic information.
Answer: nucleic acids
◉ monomers are monosaccharides
Answer: carbohydrates
◉ Functions include immediate and long-term energy storage.
Answer: carbohydrates
◉ Plantae
Answer: multicellular, photosynthetic organisms
◉ Fungi
Answer: multicellular organisms comprised of filaments that obtain
their food by absorption
◉ animalia
Answer: multicellular organisms that ingest their food
