  Domain

  kingdom

  phylum

  class

  order

  family

  genus

  species
• biological species concepts means that members of the same species can intervreed
• biological species concept important to the scientists is because it gives them a snapshot of evolution of new species in many group if plants and animals
• biodiversity is the variation of living organisms from different sources.
• slaivary amylase - breaks down starches into simpler sugar
• pepsin - break downs proteins
• peptidase - breakdown proteins into amino acids
• Mouth -start of mechanical digestion
• Tongue - pushes the bolus into the Pharynx which is the passageway for air, food, and water.
• food is then delivered to the esophagus.
• Stomach- start of initial protein digestion.
• Small Intestine - site for nutrient absorption and final digestion.
• Large intestine - It absorbs water from the remaining undigested material
• Maltase, lactase, sucrase -Breaks down sugars into simpler mlecules
• Trypsin and Chymotripsin - Continue the breakdown of proteins
• Amylase - Continues the breakdown of starches
• Lipase - Aids in breaking down fats
• biomass is the total mass if an organism in a food chain or a food web
• food web is a complex interconnected group of food chain
• oxygen-carbon dioxide shows interdependence between plants and animals for these important gases.
• mitosis produces 2 diploid identical daughter cells
• meiosis produces 4 haploid daughter cells
• 4 spermatids are formed after spermatogenesis
• 1 ootids and 3 polar bodies are formed after oogenesis
• when plant photosynthesize, they use carbon dioxide and produces oxygen.
• oxygen produced by plant in photosynthesis is used by animals to respire.
• during respiration, plants use oxygen and produces carbon dioxide
• animals take in oxygen from the atmosphere and give off carbon dioxide during respiration
• nitrogen fixation - the process of combining nitrogen with hydrogen to form ammonia
