The Cell
The cytoskeletal component responsible for vesicle transport, cell shape, and separating chromosomes during mitosis.
What are microtubules?
The mass of all living organisms in a given trophic level is called this.
What is biomass?
The pacemaker of the heart is located in this specific node within the right atrium.
What is the sinoatrial node?
These are different versions of the same gene that may result in different phenotypes.
What are alleles?
This gentle, inflatable healthcare robot from a Disney movie could easily major in biomedical engineering.
What is Baymax?
These flattened membrane-bound sacs in the Golgi apparatus are responsible for modifying and sorting proteins.
What are cisternae?
The random movement of alleles in a population due to chance events is called this.
What is genetic drift?
This valve prevents backflow of blood from the right ventricle into the right atrium.
This type of mutation occurs when a single nucleotide is changed, potentially altering one amino acid in a protein.
What is a single point mutation?
This adaptation of a Dr. Seuss book warns of species loss due to deforestation and habitat destruction.
What is The Lorax?
This process allows a cell to selectively degrade its own organelles using lysosomes, often in response to stress or starvation.
What is autophagy?
This ecological term describes the maximum population size that an environment can sustainably support.
What is carrying capacity?
This white matter tract connects the two hemispheres and allows for interhemispheric communication.
What is the corpus callosum?
In humans, crossing over occurs during this phase of meiosis, which increases genetic diversity.
What is prophase I of meiosis?
This post-apocalyptic film dramatizes humans fighting over water, illustrating the concept of carrying capacity.
What is Mad Max?
This organelle is the main site of lipid synthesis, detoxification, and calcium storage in eukaryotic cells.
What is the smooth endoplasmic reticulum?
This type of species can drastically alter the structure of an ecosystem, such as wolves reintroducing trophic cascades in Yellowstone.
What is a keystone species?
This muscle is the only one in the human body to attach directly to the periosteum of the clavicle and sternum while spanning the neck.
What is the sternocleidomastoid?
When a phenotype is determined by two or more genes it is called this.
What is a polygenic trait?
In Mr. Robot, Elliot’s dissociative episodes mirror dysfunction in this brain structure that links emotion and memory.
What is the amygdala?
Ribosomes in eukaryotic cells are made up of two subunits of these sizes (in Svedberg units).
What is 40S and 60S?
This model of population growth accounts for resource limitation and carrying capacity, unlike the exponential growth model.
What is logistic growth?
This cranial nerve, the longest in the body, innervates structures in the thorax and abdomen and is vital for parasympathetic control.
What is the vagus nerve?
These short sequences of DNA can move within the genome and are sometimes called “jumping genes.”
What are transposons?
In Gattaca (1997), society favors “valids” with genetically engineered traits, a scenario echoing this controversial real-world technology that can be used to cut or insert genes in embryos.
What is CRISPR?
