The physical manifestation of an organism genes is its Correct Answer-Phenotype T/F The carotenoids and other accessory pigments in the Chloroplast help capture light into the reaction center's chlorophyll molecules Correct Answer-True ——- is the main light-capturing molecule in chloroplasts and is responsible for giving leaves their characteristic green color Correct Answer-Chlorophyll What type of allele produces its effects in only homozygous individuals? Correct Answer-Recessiv...

Basic reactor theory lesson 1&2 PHYSICS/SCIENCE LATEST EDITION 2024/25 GUARANTEED GRADE A+ Binding energy The energy equivalent of the mass defect; the amount of energy released when a nucleus is formed from its component parts, also the amount of energy that must be supplied to a nucleus to separate it into its components Bohr model A model of the atom proposed by Nobel Laureate Niels Bohr in 1913 that describes the atom as composed of a dense, positively-charged nucleus with electrons orbi...

Fertilization Correct Answer-joining of a sperm and an egg to form a diploid zygote Organisms that use external fertilization Correct Answer-most animals who participate in this live in aquatic environments like tadpoles -tend to produce large number of gametes How are gametes released for external fertilization Correct Answer--gametogenesis occurs in response to environmental cues( lengthening days and warmer water temperatures) that indicate a favorable season for breeding -gametes are...

Activation energy - Energy needed to get a reaction started Active transport - The movement of materials through a cell membrane using energy; from a low concentration to a high concentration until it reaches disequilibrium. Adenine - The base that pairs with Thymine in DNA, and Uracil in RNA Aerobic cycle - Glycolysis -> Kreb's cycle -> ETC Aerobic respiration - Cellular respiration that requires oxygen Allele - Different forms of a gene Anaphase - Phase of mitosis in which the ch...
