Water
This type of bond forms between water molecules, making water cohesive
What is a hydrogen bond?
This is the total magnification of a microscope with a 10x eyepiece and a 40x objective lens.
What is 400x?
These specialized cells in the human body are responsible for carrying oxygen.
This phase of mitosis is when chromosomes align in the middle of the cell.
What is metaphase?
This bone is the strongest and longest bone in the body.
What is the femur?
This property of water allows insects like water striders to walk on its surface.
What is surface tension?
This organelle is the site of ATP production in eukaryotic cells.
What is the mitochondrion?
This model describes the structure of the cell membrane as a mosaic of proteins in a lipid bilayer.
What is the fluid mosaic model?
During this phase, sister chromatids are pulled apart to opposite poles.
What is anaphase?
This is the largest organ in the human body by surface area.
What is the skin?
This phenomenon explains water climbing up narrow tubes, aiding plant transport
What is capillary action?
These structures, found only in plant cells, are responsible for photosynthesis.
What are chloroplasts?
This term describes the movement of molecules from high to low concentration without energy.
What is diffusion?
This structure forms during cytokinesis in plant cells to divide the cytoplasm
What is the cell plate?
These ancient organisms, capable of photosynthesis, were responsible for introducing oxygen into Earth’s atmosphere billions of years ago
What are cyanobacteria (or blue-green algae)
This adaptation of aquatic mammals like seals minimizes heat loss in water, which has a high thermal conductivity compared to air.
What is blubber (or thick insulating fat layers)?
This is the mathematical formula to calculate magnification using image size and actual size.
What is magnification = image size ÷ actual size?
The pump responsible for maintaining resting potential in nerve cells moves these ions.
What are sodium (Na⁺) and potassium (K⁺) ions?
This term describes the point on a chromosome where spindle fibers attach.
What is the centromere?
This is the only animal that has fingerprints so similar to humans, they can confuse crime scene investigations.
What is a koala?
This physical property of water provides buoyancy, enabling aquatic organisms like fish to move efficiently without sinking.
What is density?
These structures in cells are used to measure sizes under a microscope and rely on calibrated scales.
What are eyepiece graticules?
This is the type of cell that insulates axons in the peripheral nervous system.
his cellular structure, composed of microtubules, organizes and separates chromosomes during mitosis.
This is the only muscle in the human body that is attached at only one end.
What is the tongue?
