Characteristics of Life
The combination of all chemical reactions that occur in an organism is called:
a. diffusion
b. metabolism
c. reproduction
d. circulation
b. metabolism
The name of the technology humans use to alter the genetic instructions in organisms
genetic engineering
Different finches had different beaks. The types of beaks made a difference in their ability to get food. These traits are called...
adaptations
What does the immune system do?
Protects the body against diseases
This is the process where animals best suited to their environment survive and reproduce.
Natural Selection
The organelle where cellular respiration occurs
Mitochondria
The organelle where DNA is found
Nucleus
The variable in an experiment that you measure
Dependent Variable
What does the circulatory system do?
Transports blood through the body
He is known as the father of evolution
Charles Darwin
The organelle where photosynthesis occurs
chloroplast
An error in the DNA sequence
Mutation
The type of transport when water is moving and does not require energy
Osmosis
What does the nervous system help your body do?
It helps your body sense things, think, and control movements.
Traits can be passed from parents to babies in this way
Inheritance
Cell transport that moves from a high to low concentration and does NOT require energy
Diffusion/ passive transport
Laboratory technique that allows scientists to separate bands of DNA molecules according to size
gel electrophoresis
The variable in an experiment that you change
Independent Variable
Why are enzymes important for the digestive system? What do they do?
They make the digestion of food quicker
This is the process by which living things change over a long time
Evolution
The outputs of cellular respiration
ATP (energy), Carbon Dioxide, Water Vapor
In addition to a phosphate group, a DNA nucleotide could contain these nucleotide bases (HINT: Apple Tree Car Garage)
adenine (A), cytosine (C), guanine (G), and thymine (T
The process of separating out mixtures of pigments is called
Chromatography
Explain how the circulatory and respiratory systems work together.
The respiratory system brings oxygen into the body and the circulatory system transports the oxygen around the body.
This happens when animals can't survive in their environment anymore.
Extinction
