UPCAT REVIEWER SCIENCE PROFICIENCY

• In taxonomy, and systematics of Kingdom Plantae, corn-bearing plants or gymnosperms are members of "Lycophyta"
• Glucagon - the hormone secreted by the B-cells found at the Islets of Langerhans enhances the convert from glucose to glycogen.
• Cytokinins - a plant hormone responsible for rapid cell division.
• Photosphere - refers to the surface of the sun.
• Lipase - the enzyme that digests fats.
• Radiation - a type of heat transfer that occurs in empty space.
• The periodic table increases across periods from left to right and decreases from top to bottom.
• Acids are considered with a pH less than 7, whilst bases are pH levels above 7 and is considered non-acidic.
• Acetic Acid - responsible for the tart taste of vinegar.
• Amines - organic derivatives of ammonia.
• Nucleus - enclosed in a double membrane and communicates with the surrounding cytosol via numerous nuclear pores. Within each nucleus contains organism's genome.
• Nucleolus - produce ribosomes, which move out of the nucleus and take positions on the RER where they are critical in protein synthesis.
• Soil texture triangle - used to classify the texture of a soil. The sides of the soil texture triangle are scaled for the percentages of sand, silt, and clay.
• Weathering regions of the world


  Regions classified based on mean annual temperature and rainfall
