A chemist finds a bottle of hydrochloric acid in his laboratory. Although the chemical is labeled properly, the concentration is not included. He decides to determine the concentration of the acid by performing an acid-base titration reaction. To perform this reaction, he adds a known volume and concentration of strong base to the acid while measuring the pH of the combined acid and base. Once a neutral pH is obtained, the reaction has proceeded to completion, and the concentration of the acid may be calculated. In this reaction, what is the dependent variable?

- Seminal vesicles nourish sperm and contribute fluid for semen.
Cardiovascular System
- The heart is located anterior to the lungs.
- The pulmonary valve prevents backflow into the right ventricle.
Digestive System
- The rectum is part of the large intestine.
- Most nutrients are absorbed in the small intestine.
- The primary function of the large intestine is to absorb water.
Scientific Method
- The independent variable is changed during scientific experiments.
- An inference is a conclusion based on evidence and reasoning.
- A null hypothesis assumes no relationship between two variables.
Chemistry and Chemical Reactions
- The reaction CaCl2 + 2NaOH → Ca(OH)2 + 2NaCl is a double replacement reaction.
- Glucose is a monomer that builds carbohydrates.
- Point mutation occurs when a single nucleotide is altered in DNA.
- A synthesis reaction is exemplified by 2Li + Cl2 → 2LiCl.
- The pH of a titration reaction is the dependent variable.
Immune System
- Antibodies are not part of the innate immune system.
- Allergies result from a hypersensitivity in the immune system, causing inflammation.
Nervous System
- The spinal cord is protected by the vertebral column.
- The somatic nervous system controls voluntary muscle actions.
- Autonomic nervous system regulates involuntary muscle functions.
Cellular Biology
- Hematopoiesis occurs in red bone marrow.

- DNA and RNA are built from nucleotides.
Genetics
- Offspring of a homozygous dominant and a homozygous recessive parent will all show the dominant phenotype.
- In a heterozygous cross, there is a 75% chance for brown eyes (B) in offspring.
- A homozygous genotype that expresses a recessive phenotype is aa.
Atomic Structure
- The atomic number indicates the number of protons in an atom.
- Carbon can form a maximum of 4 bonds due to its four valence electrons.
