Genetics
This molecule carries the genetic instructions used for growth, development, and reproduction.
What is DNA?
This is the largest organ of the human body.
What is the skin?
Known as the “powerhouse of the cell,” this organelle produces most cellular ATP.
What is the mitochondrion?
Antibiotics are primarily used to treat infections caused by this type of microorganism.
What are bacteria?
At standard atmospheric pressure, pure water freezes at this temperature in Celsius.
What is 0°C?
DNA uses four bases. Three are adenine, cytosine, and guanine. Name the fourth.
What is thymine?
These tiny structures in the lungs are the primary sites of gas exchange.
What are alveoli?
This structure controls what enters and leaves the cell.
What is the cell/plasma membrane?
This type of blood cell is primarily responsible for carrying oxygen.
What is a red blood cell / erythrocyte?
This scientist is famous for his pea-plant experiments that helped establish the basic laws of inheritance.
Who is Gregor Mendel?
This process uses DNA as a template to produce RNA.
What is transcription?
This organ produces insulin and glucagon to regulate blood glucose.
What is the pancreas?
These cellular structures translate mRNA into proteins.
What are ribosomes?
Vaccines expose the immune system to antigens so that these long-lived cells can help produce a faster response during future exposure.
What are memory cells?
A solution with a pH of 3 has how many times greater hydrogen-ion concentration than a solution with a pH of 5?
What is 100 times?
Two heterozygous parents, Aa × Aa, have a child. What is the probability the child is aa?
What is 25%?
This part of the brain is particularly important for balance and coordination.
What is the cerebellum?
During this stage of mitosis, chromosomes line up along the middle of the cell.
What is metaphase?
HIV primarily targets immune cells carrying this surface molecule.
What is CD4?
This element makes up roughly 78% of Earth's atmosphere.
What is nitrogen?
A DNA coding strand reads 5′-ATG GAA TGC-3′. If GAA mutates to GAG but the amino acid stays the same, what type of mutation occurred?
What is a silent mutation?
Blood returning from the body enters this chamber of the heart before traveling to the lungs.
What is the right atrium?
A red blood cell placed in a strongly hypotonic solution will undergo this process because water moves into it.
What is lysis / hemolysis?
A patient has Type O negative blood. In an emergency involving red blood cell transfusion, this blood type is traditionally called the universal donor. Why?
It lacks A, B, and Rh(D) antigens on the red cells.
Humans and giraffes have the same number of these bones in their necks despite their enormous difference in neck length.
What are cervical vertebrae (7)?
