- The pancreas is the organ responsible for producing insulin and glucagon, essential for regulating blood sugar levels.
Atomic Structure and Charge
- An atom with 32 neutrons, 17 protons, and 19 electrons has a negative charge due to having more electrons than protons.
AIDS and the Immune System
- AIDS impairs the immune system by preventing helper T-cells from activating cytotoxic T-cells and B-cells, impacting immune response.
Quantitative Research Method
- Tracking drug dosage and blood levels represents a quantitative research method focused on numerical data collection.
Truth About DNA
- DNA contains nucleotides A, T, C, G, is double-stranded, and is read from 5' to 3'.
- DNA is NOT read from 3' to 5'; this statement is false.
Primary Absorption Site in Small Intestine
- The jejunum is the main region for nutrient absorption in the small intestine.
Examples of Human Body Proteins
- Proteins include keratin (found in hair), hemoglobin (oxygen transport), and enzymes (biological catalysts).
Scientific Method Process
- Prior to forming a hypothesis, researching previous studies provides background and understanding of the topic.
Reasoning in Theory Development
- An FBI agent studying individual cases and forming theories exemplifies inductive reasoning, moving from specific observations to broader generalizations.
