Spike protein
A variety of animal cells are shown. What is responsible for animal cells having different structures?
Cell respiration occurs at different rates in each cell type
Genes are added and deleted to allow for cell differentiation to occur
Mitosis occurs at different rates in each cell type
Specific genes are activated or deactivated by environmental factors
An octopus is able to regrow a lost tentacle as shown in the picture. This process involves the rapid production of new body cells. Which statement correctly describes the cellular processes required for this type of growth?
The octopus uses meiosis to create the diploid cells needed for the new arm
Before the cells can divide, DNA must be replicated during interphase
The new arm is formed when existing cells in the body get larger
The organism relies on mitosis to produce genetically identical cells for the new arm
Which correctly identifies the functions of a lipid?
Lipid provides insulation and energy storage
Lipids catalyze reactions
Lipids only provide energy
Which statement accurately describes the energy transfer in cellular respiration?
Solar energy → thermal and chemical
Thermal energy → chemical
Chemical → thermal and chemical
Chemical → solar energy
A snake can be damaged by various factors, including environmental conditions or injuries from predators or humans. This damage can leave the snake vulnerable to infections, which can travel through the bloodstream and cause sepsis, a life threatening blood infection. Which three body systems interact to repair, defend and provide protections to the turtle?
Integumentary, reproductive, and nervous system
Skeletal, immune, and digestive
Circulatory, integumentary, and immune
Muscular, endocrine, and circulatory
Meiosis is significant because –
Allows multicellular organisms to grow in size
Provides identical offspring
Provides genetic diversity by crossing over
Requires more chromosomes
A primary function of nucleic acids within the cell is to –
Provide energy
Supply insulation
Carry genetic material
Speed up chemical reactions
How do viruses such as HIV and influenza spread in the body
The virus use host cells to replicate DNA or RNA to make more viruses
The virus consumes body cells through phagocytosis
The virus absorbs vital nutrients, weakening over time
The virus multiplies uncontrollably, causing abnormal cell growth
When the enzyme is denatured or broken and loses its shape, what is affected
Substrate will not bind
Reaction will increase
Different product will be formed
Substrate will change shape
What occurs during meiosis to create genetically different haploid gametes. Select two
Crossing over
Spindle fiber formation
Cytokinesis
Independent assortment
Cell growth and repair
What structures are found eukaryotic but not are not present in prokaryotic. Select two

Cytoplasm
Which statement best describes the effects of cancer cells in the cell cycle?
Controlled division and formation of identical somatic cells
Damage to DNA and rapid rate of cell division
Immediate destruction of organelles and cell death
Regulated gene expression and the production of cyclins
When water levels in the body are low, the circulatory and endocrine systems work together with the excretory system to decrease the amount or urine produced. Which statement best describes how the system interact
Neurons send signals to increase water levels so that nutrients can be more easily absorbed in the small intestines
Glands release hormones that trigger certain blood vessels in the kidney to constrict, increasing water levels in the body
Where does DNA synthesis/replication take place?
G1
S
G2
M
A = translation
B = translation
A = transcription B = mRNA
A = translation
B = translation
What is the complementary DNA sequence to the template above. Remember DNA to DNA is A-T and C-G
ACTTAG
ACUUAG

Digestive
Muscular
Endocrine
Circulatory
Immune
Which statement best describes the process occurring in the image?
Translation of the code on the mRNA into a polypeptide chain using the amino acids attached to the tRNA molecules
Transcription of a new mRNA by RNA polymerase using DNA as a template to create a new polypeptide chain
Translation of the code on the tRNA into a polypeptide chain using amino acids attached to the mRNA molecules
Transcription of the code on the mRNA into a polypeptide chain using amino acids attached to the tRNA molecule
Bipolar disorder is an inherited disorder.The gene for bipolar (B) is dominant to the unaffected gene (b) Both parents are heterozygous for this gene. What is the percentage that the children will not be bipolar. Remember, non bipolar kids will be completely little letters.
25%
50%
75%
100%
Which description explains the type of energy transfer that occurs in the mitochondria through cellular respiration?
Solar energy of glucose is transferred to cellular energy
Chemical energy of glucose is transferred to ATP
Cellular energy of atp is transferred to glucose
Solar energy of ATP is transferred to glucose
A gene segment has the original DNA base sequence on its nontemplate strand 3’ TAC CCT GAG 5’ A mutation occurs, resulting in the new sequence 3’ TAC CCC GAG 5’ Based on the information in the mRNA codon chart, what is the significant change?
The mutation is silent because the new codon codes for the same amino acid, leaving the protein unchanged
The mutation causes a frameshift because a base was inserted, altering all subsequent amino acids
The mutation is missense because the new codon codes for a different amino acid, which may alter the proteins function
The mutation is nonsense because the new codon is a stop codon, which will terminate protein synthesis prematurely
Which is correctly paired. Remember Starch gives you ATP
Cellulose → Storage of energy
Starch → Structure support in the cell wall
Glucose → Used in respiration to produce ATP
Cellulose → Structure support in the cell wall
Starch → Storage of energy
Glucose → Used in respiration to produce ATP
