The process is labeled with an "A" is --
Replication, which is the formation of new alleles
Translation, which is the process that convert mRNA
Transcription, which is the process of transcribing a sequence of DNA to RNA
Recombination, which ensures that each cell has one complete set of instructions
The process labeled "B" is --
Replication, which DNA makes a copy of itself
Translation, which is the process that converts mRNA to proteins
Transcription, which is the process of transcribing DNA to RNA
Translation, which is the process of converts DNA to RNA
In this photo-micrograph of an onion root tip, what phase of mitosis is occurring in cell A?
Anaphase
Interphase
Prophase
Telophase
What is the correct order that depicts mitosis?
3-4-5-1-2
1-2-3-4-5
2-3-5-2-1
3-4-5-2-1
Which of the following statements are correct? D
D is prophase; chromosomes are present
C is telophase; 2 daughter cells with chromatin is present
B is telophase; chromatids at opposite poles
C is Telophase; cell plate present with 2 daughter cells
Which statement is true about the process of cellular respiration?
Carbon dioxide is required
Sugar is produced
Oxygen is consumed
It occurs in the chlorplast
Which molecule is synthesized by the mitochondria for cellular processes in both plants and animals
Glucose
Oxygen
Chlorplasts
Adenosine triphosphate (ATP)
Which statement is true about the process of photosynthesis?
Carbon dioxide is produced
Sugar is produced
Oxygen is consumed
It occurs in the mitochondria
Components of DNA include a phosphate backbone and base pairs connected by a --
Covalent bond
Carbon bond
Hydrogen bond
Ionic bond
The order of the nitrogenous base in DNA determine -
the genetic code
the presence of polarity
the presence of hydrogen bond
if there is a 7th nitrogen base
Differences in traits such as hair texture are determined by differences in -
the location of sugar groups in DNA
the sequence of nucleotides in DNA
the sequence of phosphates in DNA
the number of hydrogen bonds
What is the significance of crossing-over during meiosis?
Genes replicate and ensure that the offspring have the same traits as the parents.
Gametes duplicate and alter the number of chromosomes present at the end of meiosis
Gametes begin with 48 chromosomes and still ahve 48 at the end of meiosis
Genes from the parents combine to increase the variety of traits expressed by their offspring
Which diagram demonstrates genetic variation during meiosis?

Gap 1 (G1)
Synthesis (S)
Gap 2 (G2)
Mitosis (M)
Which organism is a prokaryotic?
Organism 1
Organism 2
Organism 3
Organism 4
Which table headings should the student use for the two groups of living things?
Animal Cells; Plant Cells
Prokaryotic Cells; Eukaryotic Cells
Viral Cells; Eukaryotic Cells
Fungal Cells; Bacterial Cells
The diagram shows an enzymatic pathway. What happens when the Enzyme B is removed?
The reaction skips enzyme B and goes to enzyme C
The reaction slows down
the reaction speeds up
the reaction stops
The diagram shows an enzymatic metabolic pathway. What happens when "cyanoase" is introduced into the reaction?
reaction skips enzyme changes to a new substance
The reaction stops.
The reaction slows down.
The reaction speeds up.
