This type of reaction links monomers together by removing a molecule of water.
What is a condensation reaction?
The structural model describing the cell membrane as a fluid combination of phospholipids and proteins.
What is the fluid mosaic model?
The type of blood vessel that carries blood away from the heart.
What is an artery?
The sugar present in RNA nucleotides.
What is ribose?
A lipoprotein that transports cholesterol to tissues, often linked to increased heart disease risk.
What is LDL?
The bond formed between two monosaccharides in a disaccharide.
What is a glycosidic bond?

What is facilitated diffusion?
The heart chambers that receive blood from the veins.
What are the atria?
The base-pairing partner of adenine in DNA.
What is thymine?

What is correlation?
The level of protein structure characterized by alpha-helices and beta-pleated sheets.
What is secondary structure?
The transport requiring ATP to move substances against their concentration gradient.
What is active transport?
The valve between the left atrium and left ventricle.
What is the bicuspid (mitral) valve?
The RNA that carries the genetic code from DNA to ribosomes.
What is mRNA?
A dietary factor that can help reduce LDL levels and heart disease risk.
What are polyunsaturated fats?
The property of water that makes it an excellent solvent for polar molecules.
What is its polarity?
The process by which cells take in large molecules via vesicles formed from the membrane.
What is endocytosis?
The blood vessels with thin walls that allow exchange of materials.
What are capillaries?
The process of synthesizing a polypeptide chain at the ribosome using mRNA and tRNA.
What is translation?
Elevated blood pressure condition increasing artery wall damage risk.
What is hypertension?
The type of lipid composed of a glycerol backbone and three fatty acids.
What is a triglyceride?
The solution that causes cells to shrink as water moves out.
What is a hypertonic solution?
he process of fatty deposit buildup in arteries leading to reduced blood flow.
What is atherosclerosis?
The process in the nucleus where a complementary RNA strand is formed from DNA.
What is transcription?
A long-term study tracking a group over time to find links between lifestyle factors and disease.
What is a cohort study?
