SCIENCE

• Assimilation - process by which the nutrients from the digested food move into the blood vessels passing through the lining of the small intestine.
• Peristalsis - wavelike contraction of the smooth muscles of digestive tract pushes food in small sections through the GASTRO-INTESTINAL TUBE
• Chemical digestion - process of turning food into smaller molecules with the aid of enzymes.
• Ingestion - animals take in food that provides energy and nutrients process of turning food into smaller molecules with the aid of enzymes
• Assimilation - Digested foods are distributed into different parts of the body cells
• Bolus - food that is chewed and mixed with saliva that turns into a moisy ball
• Villi - increases surface area for nutrient absorption
• Teeth - BREAKS down food into tinier pieces to begin mechanical digestion
• Amylase - enzyme present in saliva helps break down STARCH
• Small intestine - final stage digestion of food happen
• Amylase - enzymes is responsible for initially breaking of food molecules that occur in the MOUTH
• Small Intestine - main digestion takes place
• Pepsin - an enzyme that digests protein in the stomach
• Digestive System - organ system is responsible for breaking down of large molecules into smaller molecules and absorption of organic compounds needed by the body
• Large Intestine - it reabsorbs water from chyme
• Metaphase - chromosomes line up at the equatorial plane
• Anaphase - CHROMATIDS seperate at the CENTROMERE
• Telophase - last phase of nuclear division
• Interphase -DNA replication occurs
• Prophase - condensed chromosomes become visible
• meiosis ll - daughter nuclei have chromosomes with single CHROMATIDS
• Meiosis l - daughter cells have chromosomes with two sister CHROMATIDS
• Meiosis ll - Results in four sperm cells in human males
• Meiosis ll - Seperation of homologous chromosomes
• Meiosis l - Occurrence of SYNAPSIS between TETRADS
• Other name for CRI-DU-CHAT syndrome is “cat cry”
• A child with KLINEFELTER syndrome has how many chromosomes? 45 chromosomes
• Characteristics of a person with PATAUsyndrome TRISOMY 21 EXCEPT: small stature
• Chromosomal abnormality - Which causes down syndrome
• Meiosis l - occurrence of crossing-over of homologous chromosome
• Sperms has the genetic information in the HEAD - TRUE
• GAMETOGENESIS is the formation of SEX CELLS - TRUE
• Primary SPERMATOCYTE produces FOUR HAPLOID SPERMATIDS - TRUE
• GAMETOGENESIS produces HAPLOID CELLS - TRUE
• Which is the main role of meiosis in GAMETOGENESIS? Sex cells A
