BIOLOGY STAAR QUIZS

MOLECULAR HOMOLOGY

• *COMPARE DNA OR AMINO ACID SEQUENCES TO SHOW COMMON ANCESTRY

• *ANALYZE PHYSICAL TRAITS TO DETERMINE RELATIONSHIP

• *STUDY ENVIRONMENTAL FACTORS AFFECTING SPECIES

• *EXAMINE FOSSIL RECORDS FOR EVOLUTIONARY TRENDS

CARBOHYDRATES

• GLUCOSE-QUICK ENERGY

• CHITIN- EXOSKELETON

• GLYCOPROTEIN- CELL SIGNALING/IDENTIFICATION

• AMINO ACID- BUILDING BLOCK OF PROTEINS

ANAPHASE

• Spindle fibers pull sister chromatids apart and away to opposite poles

• Chromosomes align at the cell's equator

• Nuclear envelope begins to reform around the chromosomes

• Chromatids are replicated and prepared for division

NGSS.HS-LS1-4

VIRUSES

• Contain a CAPSID and NUCLEIC ACIDS

• Can replicate independently without a host cell

• Are considered living organisms

• Have only a lytic cycle

SEXUAL SELECTION

• Most favorable trait gets chosen to reproduce

• All traits are equally chosen for reproduction

• Only the strongest males reproduce

• Reproduction is random without preference

MEIOSIS

• *PROCESS OF MAKING SOMATIC CELLS

• *MAKES 2 DIPLOID UNIQUE CELLS

• *PROCESS OF MAKING GAMETES (SPERM /EGG CELLS)

• *DECREASES GENETIC DIVERSITY DUE TO CLONING

DENATURE

• EXTREME CONDITIONS CHANGE SHAPE OF ENZYMES

• ENZYMES WORK BEST AT ROOM TEMPERATURE

• DENATURED ENZYMES INCREASE REACTION RATE

• ENZYMES ARE UNCHANGED BY TEMPERATURE

GENETIC DRIFT

• *CHANGE IN GENE POOL CAUSING A DECREASE IN GENETIC VARIATION BY CHANCE OR DISASTER

• *INCREASE IN GENETIC VARIATION DUE TO NATURAL SELECTION

• *RANDOM MATING LEADING TO UNCHANGED GENE POOL

• *SYSTEMATIC ELIMINATION OF WEAKER GENES BY ENVIRONMENTAL FACTORS

FOUNDER EFFECT

• TYPE OF GENETIC DRIFT WHERE A NEW POPULATION IS CREATED WITH VERY FEW VARIATION

• A PROCESS WHERE A POPULATION BECOMES EXTINCT DUE TO ENVIRONMENTAL CHANGES

• A FORM OF NATURAL SELECTION THAT FAVORS AVERAGE PHENOTYPES

• A MECHANISM OF EVOLUTION THAT INVOLVES RANDOM MATING WITHIN A POPULATION

DIGESTIVE SYSTEM

• *HELP BREAK DOWN FOOD AND MOVES NUTRIENTS THOUGH THE INTESTINES

• *PRODUCE HORMONES FOR METABOLISM

• *FILTER TOXINS FROM THE BLOOD

• *STORE ENERGY IN THE FORM OF FAT
