NVCC BIO 101 Exam 2 with Complete Solutions Metabolism the totality of an organism's chemical reactions Metabolic pathway Begins with a specific molecule, which is then altered in a series of defined steps, resulting in a certain product. catabolic pathway release energy by breaking down complex molecules into simpler compounds anabolic pathways consume energy to build complex molecules from simpler ones - proteins are synthesized from simpler molecules called amino acids ...

What is Biology? Correct Answer-Study of life; encompasses everything -biomolecular biology and technology have brought around a new era for biology What are the major characteristics of Life? Correct Answer-1) reproduction (DNA (deoxyribose nucleic acid); double helix shape; stores genetic info) 2) cellular repsiration (used to creat energy) (metabolism; need it to perform basic functions of life; food (carbs, proteins, lipids/fats, vitamins/minerals) 3) adaptation/evolve (over large peri...

WVU Bio 101 Exam 3 Salihu Questions and Answers Already Passed In a eukaryotic cell, where does DNA replication occur? nucleus base mutation do not alter reading frame base insertions or deletions alter reading frame, typically more disasterous than base mutation when do mutations occur? may be spontaneous or may be caused by environmental factors called mutagens do daughter cells have the same number of chromosomes as the parent cell? yes how many daughter cells are creat...

WVU BIO 101 EXAM 2 QUESTIONS AND ANSWERS 100% PASS Enzymes are actually which type of macromolecule? Proteins Characteristics of living things -Use energy - thus they metabolize proteins, lipids, and carbohydrates to release the energy stored within them What is metabolism? -All chemical reactions that occur in living organisms to maintain life -Includes breaking down molecules and building new molecules Enzyme properties 1. Specific 2. Sensitive to environmental conditons 3....

How many alleles does one gene have? - Answer- Two Allele - Answer- different versions of the same gene Dominant allele - Answer- "covers" the effects of the recessive version; dominant genes show up in the phenotype (AA) Recessive allele - Answer- "shows" in the phenotype when dominant allele isn't present (aa) Phenotype - Answer- Physical appearance Genotype - Answer- the alleles that are internal Heterozygous - Answer- Ff Homozygous dominant - Answer- FF Homozyg...
