• During winter, animals are likely to undergo thermogenesis.
• In esterification, the OH group comes from alcohol.
• Four carbon atoms are required to form a furan ring (ribofuranose).
• Sleep movements are a type of turgor movements.
• The keto group is represented as CO.
• Habituation is the type of learning involving a loss in response to repeated stimuli.
• Glycolipids and glycoproteins have a structural role in the extracellular matrix.
• Interstitial cells in testes secrete testosterone.
• In Cx(H2O)y, x ranges from 3 to many thousand.
• Exposure to low temperatures stimulates plants to flower, known as vernalization.
• The basic structural unit of a chromosome is the nucleosome.
• Water acts as a lubricant protecting against friction-induced damage.
• The first stage of development with a cavity is the blastula.
• Glyceraldehydes and dihydroxy acetone are intermediate trioses in respiration and photosynthesis.
• Oxytocin causes contractions of the uterine wall during and after birth.
• Tetroses are monosaccharides found in some bacteria.
• Transcription of DNA produces mRNA.
• Triglyceride is also known as a neutral lipid.
• Carbon commonly combines with H, N & O, P & S.
• The sequence of 3 bases on tRNA complementary to the mRNA codon is the anticodon.
