Cumulative Biology Review Assessment (2012)

What will most likely be the result if all of the mitochondria are removed from a plant cell?

• it will be unable to carry out respiration

• it will lose water through osmosis

• it will break down the ribosomes in the cell

• it will be unable to photosynthesize

What process best explains how a nerve cell and a muscle cell can both develop from teh same fertilized egg?

• differentiation

• natural selection

• selective breeding

• genetic engineering

During strenous exercise, body temperature increases. The body responds by sweating, which helps to reduce body temperature. Which is demonstrated in this situation?

• excretion

• metabolism

• homeostasis

• synthesis

Before mitosis begins, which happens before the nucleus starts dividing?

• the cytoplasm separates

• the DNA replicates

• the sister chromatids separate

• the homologous chromosomes cross over

What is the function of autotrophs in the carbon cycle?

• to use oxygen to produce glucose

• to take in excess water

• to use carbon dioxide to produce glucose

• to feed on herbivores

Two different populations of birds live in the same area and eat the same types of food. Which most likely describes the relationship between these two populations of birds?

• competition

• mutualism

• parasitism

• predator-prey

What will most likely happen if the human population continues to grow at the current rates?

• there will be fewer natural resources available

• there will be an increase in nitrogen levels

• there will be a decrease in water pollution

• there will be an increase in the number of strong hurricanes

A strand of DNA has these bases: AGC - CAT - GTA - TAC

What is the complimentary DNA strand?

• ACG - GAT - CTA - TAG

• TCG - GTA - CAT - ATG

• TGC - CTA - GAT - ATC

• UCG - CUA - CAU - AUG

Which statement best describes the relationship that exists among proteins, DNA and cells?

• proteins combine to produce cells, which produce DNA

• proteins are made of up of DNA, which determines the cells that are produced

• DNA is made up of proteins, which tell a cell how to function

• cells contain DNA, which controls the production of proteins

Why is meiosis important for sexual reproduction?

• it allows the zygote formed from fertilization to have triple the chromosome numbers of the organism

• it allows gametes to havve twice the original number of chromosomes of the organism

• it allows gametes to have half the original number of chromosomes of the organism

• it allows the zygote formed from fertilization to have half the original number of chromosomes of the organism
