Characteristics of Life
The simplest building block of life.
What are Cells?
The organelle that provides the compartmentalization for the cell. It is the outer protection.
The rule that atoms follow (with some exceptions) to become more stable and form compounds
What is the octet rule?
This is matter that is made of identical atoms.
What is a pure substance - element?
The substance that is dissolved in the solvent
What is the solute?
The change that happens over generations (and due to reproduction) that allows life to adapt to changing environments.
What is evolution?
The jelly insides of a cell that provides structure, where all the chemistry of life happens.
What is the cytoplasm?
The process that protons and neutrons join together to form atoms.
What is nuclear fusion?
This is the matter that contains more than one type of molecule but appears to be the same throughout.
What is a homogeneous mixture?
The solution that is formed with the maximum of solute that can dissolve in the solvent under certain conditions.
What is a saturated solution?
The process of getting and processing energy that is stored in the bonds of macromolecules.
What is metabolism?
The genetic material found in all cells that can self-replicate.
What is DNA? (RNA also accepted)
These are two of the three functions that macromolecules must provide to living cells.
What are compartmentalization, self-replication or metabolism (2 of the 3)?
This is a combination of more than one pure substance that has visibly different parts.
What is a heterogeneous mixture?
A homogeneous mixture formed by dissolving a solute into a solvent.
What is a solution?
This is the process that life does to internally regulate conditions like temperature, pH, hydration, glucose...
What is homeostasis?
These are the organelles that join amino acids into proteins. The are found in all living cells.
What are ribosomes?
This is the type of molecule that was produced with energy over time from simple molecules in the Miller-Urey experiment.
What are amino acids?
This is matter that has identical smallest units but is made of more than one type of atom.
What is a pure substance - compound?
What water is considered because it is polar and dissolves many different ionic and polar substances.
What is the universal solvent?
This is the process that assumed life can come from non-living material. It was shown false by Redi's experiment.
What is spontaneous generation?
The is a membrane bound organelle that converts carbohydrates into energy molecules known as ATP to be used by many parts of the cell.
What is the mitochondria?
The two necessities for the universe to change from simple to complex.
What are time and energy?
The type of bond that is formed between strontium (Sr) and selenium (Se).
What is an ionic bond?
A solution where the solute is appearing because the conditions have been changed.
What is a supersaturated solution?
