Advanced Genetics
This term refers to the physical expression of a gene.
What is phenotype?
This term refers to the process in which two species evolve in response to each other.
What is coevolution?
The thin-walled air sacs in the lungs where gas exchange (oxygen and carbon dioxide) occurs.
What are alveoli?
The experiment involving placing a potato slice in solutions of varying salt concentrations demonstrates the movement of water across a semipermeable membrane, a process called this.
What is osmosis?
I’m made of 46 parts, but lose half when you make me a baby. What am I?
What is a chromosome set (or genome)?
This process allows bacteria to exchange plasmids through direct contact.
What is conjugation?
This term describes the total variety of life on Earth, encompassing genetic, species, and ecosystem diversity.
What is biodiversity?
This valve prevents backflow of blood from the left ventricle into the left atrium.
What is the mitral (or bicuspid) valve?
In Mendel’s dihybrid cross experiments, what phenotypic ratio did he observe in the F₂ generation?
What is 9:3:3:1?
I’m your body's messenger, but I don’t use words. Who am I?
What is a hormone (or neuron)?
This chromosomal abnormality results in a male with an extra X chromosome.
What is Klinefelter syndrome (XXY)?
The process by which organisms better adapted to their environment tend to survive and produce more offspring.
What is natural selection?
This autoimmune disease attacks the myelin sheath in the central nervous system.
What is multiple sclerosis?
In an experiment studying enzyme activity, increasing the temperature beyond the optimal point would likely lead to this irreversible change in the enzyme's three-dimensional structure.
What is denaturation?
I’m a liquid with no color that transports the tiny soldiers of your body.
What is blood plasma?
In a pedigree, this inheritance pattern often skips generations and affects both sexes equally.
What is autosomal recessive?
This specific type of population growth pattern is characterized by a "J-shaped" curve, indicating rapid, unrestricted growth.
What is exponential growth?
This is the primary neurotransmitter released at neuromuscular junctions.
What is acetylcholine?
In plasmolysis experiments using onion epidermis, what is the visible sign that water has left the cell?
What is shrinking of the cytoplasm away from the cell wall?
I’m a deadly invader with no cells, no metabolism, no heart. Yet I hijack your systems and tear you apart. What am I?
What is a virus?
When a single gene affects multiple distinct phenotypic traits.
What is pleiotropy?
This type of species interaction benefits one species and harms the other, such as a tick feeding on a dog.
What is parasitism?
This area of the brain, typically in the left hemisphere, is crucial for speech production and articulation.
What is Broca's area?
Which food test requires two reagents to be added in sequence—sodium hydroxide followed by copper sulphate?
The Biuret test for proteins.
I’m the quiet conductor of your cells’ activity. I don’t speak, but I signal with electricity. What am I?
What is a neuron?
