The Euglena is a unique protist because it can make its own food using sunlight like a plant, but it can also swim around like an animal. What is the name of the organelle inside the Euglena that allows it to perform photosynthesis?
Chloroplast
If a liquid moves from a pH of 5 to a pH of 2, does it become more acidic or more basic?
Acidic
This system acts like a "security fence" for your body, using skin and mucus to keep germs out.
Integumentary
Scientists look at a diagram called a Cladogram. If two animals are branching off from the same line, what does that tell us about them?
Common Ancestor
This is the specific process where one "parent" cell divides to create two identical "daughter" cells.
Mitosis
A plant is placed in a hot, dry environment. To prevent too much water loss through transpiration, which small openings on the underside of the leaves will close?
Stomata
If a substance like pure water has a pH of 7, how would a scientist classify that liquid?
Neutral
When you get a vaccine, your body produces these Y-shaped proteins to "remember" and fight off specific germs in the future.
Antibodies
A human’s arm, a bat’s wing, and a whale’s flipper all have the same bone structure, even though they look different. What is the name for these similar structures?
Homologous
If a cell's DNA is damaged or not copied correctly, these "stop signs" in the cell cycle will prevent the cell from dividing until the mistake is fixed.
Checkpoints
What structure in a plant cell could be missing from an animal cell ?
Cell wall, Chloroplast, or Large Central Vacuole
The Green Basilisk Lizard is able to run across the surface of a pond without sinking. Which property of water creates a "film" on the surface that supports the lizard's weight?
Surface Tension
due to COhesion
If a person has high blood pressure, it means the heart is working harder to push blood through the vessels. Which factor would increase blood flow resistance?
High Viscosity
In science, a Law describes what happens in nature (Law of Gravity). What does a Theory do?
It explains the HOW
During the Cell Cycle, a cell must duplicate its DNA before it can divide. In which specific sub-phase of Interphase does DNA replication occur?
S Phase
What are the Products of Photosynthesis
Glucose and Oxygen
Lactase is an enzyme that breaks down lactose, a type of sugar found in milk. Lactase functions best between 21C and 48C, and at a pH between 2 and 7.
Which of the following would happen to lactase and lactose if the temperature and pH fell far outside these ranges?
The lactase would be unable to break down the lactose.
When a sperm cell and an egg cell combine during fertilization, they form a single, new cell. What is the scientific name for this fertilized egg?
Before a scientist can publish their results in a professional journal, other experts in the same field must check the work for mistakes, bias, or unfair testing. What is this "quality control" process called?
Peer Review
Most of a cell's life is spent in a non-dividing stage where it grows and performs its normal functions. What is the collective name for G1, S, and G2?
Interphase
A scientist wants to determine if the amount of sunlight affects the growth rate of a specific type of tomato plant. She sets up four groups of plants with identical soil, water, and temperature conditions. Group A receives 2 hours of sunlight, Group B receives 4 hours, Group C receives 6 hours, and Group D receives 8 hours.
What is the independent variable in this experiment?
Amount of Sunlight
What biological molecule could be used to lower the activation energy in a reaction?
Enzyme
If a human sperm has 23 chromosomes and a human egg has 23 chromosomes, how many chromosomes are found in the Zygote?
46
During meiosis, the way one pair of chromosomes lines up does not affect how any other pair lines up. This "random shuffling" of genes ensures that every egg and sperm cell is unique. What is this law called?
Independent Assortment
During which specific part of the M-Phase do the two new nuclei actually form around the separated chromosomes?
Telophase
