Cell Structure & Function
this organelle is responsible for generating energy for the cell
what is the mitochondria?
these are the building blocks of dan
what are nucleotides?
this scientist is credited with proposing the theory of natural selection
what is Charles Darwin?
this behavior occurs automatically in response to a stimulus
what is reflex?
This process involves the movement of molecules from an area of high concentration to an area of low concentration.
what is diffusion?
This organelle is responsible for protein synthesis in the cell.
what is the ribosome?
This term describes the genetic makeup of an organism.
what is genotype?
This mechanism of evolution involves the random change in allele frequencies in a population.
what is genetic drift?
This term describes the transmission of signals between animals.
what is animal communication?
This pigment absorbs light energy in photosynthesis.
what is chlorophyll?
This process allows molecules to move across the cell membrane without the use of energy.
what is passive transport?
This process involves the exchange of genetic material between homologous chromosomes during meiosis.
what is crossing over?
This term describes traits that increase an organism's chance of survival and reproduction in a particular environment.
What are adaptations?
This term describes the regular, seasonal movement of animals from one region to another.
what is migration?
This enzyme is responsible for unwinding and separating the DNA strands during replication.
What is DNA helicase?
This phase of the cell cycle occurs after DNA replication and before cell division.
what is the g2 phase?
This molecule serves as the template for protein synthesis.
what is mRNA?
This term describes the process by which two unrelated species evolve similar traits due to sharing a common ancestor.
what is divergent evolution?
This term describes the biological clock that regulates the sleep-wake cycle and other physiological processes.
what are circadian rhythms?
This type of cell junction allows for direct communication and the passage of ions and small molecules between adjacent cells.
what is gap function?
This cellular structure is responsible for packaging and transporting materials within the cell.
what is the Golgi apparatus?
Down syndrome is caused by the presence of an extra copy of this chromosome.
what is chromosome 21?
This diagram is used to represent evolutionary relationships among organisms.
what is a phylogenetic tree?
This term describes the behavior of providing care and protection to offspring after birth or hatching.
what is parental investment?
This process involves the movement of large molecules into the cell by engulfing them in a vesicle.
what is endocytosis?
