Characteristics of Life and Scientific Inquiry
This is the study of life
Biology
All organic compounds contain this element.
Carbon
This type of cell is small, does not have membrane bound organelles, and does not have a nucleus
prokaryote
This is the name for the process where plants capture energy and make complex molecules.
Photosynthesis.
Acquired characteristics do not show that organisms do this, or change over time
Evolve
This is a testable possible explanation of an observation.
Hypothesis
Sucrose is this type of macromolecule
Carbohydrate
If a cell is very active, it may contain large amounts of these organelles.
Mitochondria
This is caused by an error in DNA replicaiton
mutations
The human tailbone is this type of structure, left over from our ancestors who had tails.
vestigial structure
This group in an experiment does not introduce the independent variable, or special treatment
Control group
Without these chemical reactions would occur too slowly to support life processes.
Enzymes
This organelle is responsible for making proteins
Ribosomes
These three things make up a nucleotide.
a sugar, a phosphate group, and a nitrogenous base
this is the movement of genes from one population to another
gene flow
This is the variable that is being tested by the hypothesis.
independent variable
These are the four main types of macromolecules
carbohydrates, lipids, nucleic acids, and proteins
This occurs to a red blood cell that is placed in a beaker containing a high salt solution?
The red blood cell shrinks.
This name for a 2n cell with two homologous chromosomes that are found in pairs.
Diploid.
Precipitation and evaporation are important components of this biogeochemical cycle.
water cycle
This is the order of the scientific method.
observation, hypothesis, predictions, controlled testing, verification, theory
This occurs in a protein when the acidity and high temperatures cause it to change shape and stop working.
denature
This is the major atmospheric byproduct of photosynthesis.
Oxygen
This is the name of reproduction is bacteria.
Binary fission
Burning fossil fuels affects which biogeochemical cycle.
The carbon cycle.
