Binomial Nomenclature — rules?
Genus capitalized, species lowercase, italicized or underlined.
Osmosis — in potato cylinders?
Water moves across membranes, affected by sucrose concentration.
Photosynthesis site — in chloroplast?
Light-independent stage occurs in the stroma.
Leaf adaptations — for photosynthesis?
Large surface area, thin cuticle.
Bile — role?
Emulsifies fats for digestion.
HCl — role?
Activates enzymes, kills microbes.
Left ventricle — wall?
Thicker than right, pumps at high pressure.
Mitral valve — location?
Between left atrium and ventricle.
Xylem — adaptation?
Lignified walls, hollow tubes, pits.
Insect gas exchange — site?
Tracheoles directly deliver gases to tissues.
Alveoli — adaptation?
Thin walls and large surface area.
Aerobic respiration — site?
Mitochondria.
Anaerobic respiration — difference?
No oxygen, less ATP, produces lactic acid or alcohol.
Kidney unit —?
Nephron.
ADH — function?
Regulates water reabsorption in kidneys.
Blood sugar — regulation?
Insulin lowers, glucagon raises blood glucose.
Fungi — characteristic?
Chitin cell walls, heterotrophic, spores.
Food chain — producer?
Synthesizes own food via photosynthesis.
Food chain — four levels?
Producer → primary → secondary → tertiary consumer.
Frog decline — effect?
Disrupts food chain, ecosystem imbalance.
Hawk — trophic level?
Top predator, usually quaternary level.
Xylem — function?
Water conduction and structural support.
Insect respiration — adaptation?
Tracheal system with spiracles.
Respiration — energy source?
Glucose breakdown in mitochondria.
