Cells/Body Systems
The smallest functional unit of an organism.
What is a cell?
A change in genetic information
What is a mutation?
What are the structures found in the nucleus that contain the genetic information?
What are chromosomes?
All living factors in an ecosystem.
What is biotic?
Photosynthesis occurs here.
- In which organelle does photosynthesis occur?
What is a chloroplast?
This organelle is known as the cell's "powerhouse", breaking down sugars and providing energy to the cell.
What is mitochondria?
Due to the poaching of elephants for their tusks, the rise in tuskless elephants caused better adaptation to their environment to survive and produce more offspring.
What is natural selection?
The gene that is not seen when a dominant gene is present (also seen as a lowercase letter).
What is recessive?
Dominant - A gene that will appear in an offspring if one parent contributes it (produces the same phenotype) (also seen as a capital letter)

What is glucose?
What is the term for physical characteristics?
What is phenotypes?

What is mitosis?
If a fish embryo and a pic embryo look similar, what can we conclude about these organisms based on embryology?
What is they share a common ancestor?
In meiosis, the new cells have ___________ the number of chromosomes as the original.
What is half?
These organisms can make their own food using light, water, and carbon dioxide.
What are producers or autotrophs?
What organelle allows food to enter and wastes to leave the cell?
What is the cell membrane?
While cells are known as the "building blocks of life", this material is known as the "blueprint of life". It is shaped like a double helix, found inside the nucleus, and it allows important characteristics to replicate and be passed on to the next generation.
What is DNA?
One of these would not be used by a scientist to determine the evolutionary relationship between two species - a. bone structure b. fossils c. DNA d. population size
What is population size?
What is the expected result of a Tt × Tt genetic cross to be homozygous recessive?T=tall t=short
What is 25% chance of the offspring being short?
An organism that lives by breaking apart dead organic matter into simpler parts is
What is a decomposer?
What are 3 evidences for evolution?
Examples: Fossil record, homologous (similar) structures, embryology (embryos look alike)
