Unit 1 - Cells
The smallest unit of life that can carry out all of the functions of life.
What is the cell?
The goal of the skeletal system.
A segment of DNA that has the ability to code for a specific characteristic.
What is a gene?
The study of how things change over time.
The study of evolution.
The combination of abiotic and biotic factors in the same area.
What is an ecosystem?
The purpose of the nucleus.
What is sending directions to the different parts of the cell and/or containing the DNA.
The purpose of flowers.
What is attracts pollinators?
What chromosomes are made of.
What is DNA?
What are the structures called that perform the same function but have different ancestries?
Analogous Structures
What will happen to the predator population if the prey population decreases.
The predator population will decrease.
The goal of the cell membrane.
What is regulating what enters and leaves the cell?
The purpose of the leaf.
What allows photosynthesis to occur?
Assume that a genetic trait is represented by the letter a. Which of the following would most likely be used to represent the recessive condition?
aa
Anatomical features in different organisms that share a common ancestry, even if they serve different functions.
Homologous Structures
The maximum population size an ecosystem can hold.
What is carrying capacity?
The organelle that aids with creating energy for the cell.
What is the mitochondria?
What systems work together to take in nutrients and excrete waste?
The excetory/urinary system and the digestive system.
Two parents each have one copy of a gene for a recessive genetic trait (they are heterozygous). What is the percent chance of their offspring inheriting the trait?
25%
The branch of biology that studies the formation and development of embryos
What is embryology?
What is mutualism?
The direction water travels during osmosis.
What systems work together to control the thought processes and then direct the muscles to carry them out?
The nervous and muscular system.
Describe what happens during a mutation. Use the terms DNA, gene, and protein.
There is a change in the DNA that affects the gene. The wrong protein may be made, or their may be no affect to the protein.
What is the most effective way to determine if two organisms share recent common ancestry?
DNA testing
What is it called when an organism dies and their carbon is returned to the soil?
Decay
