Intro. to Science
Maintaining a stable internal environment is called _____________.
Homeostasis
reactants have to ___________ the products of a chemical reaction.
equal
Organic molecules must contain ______________.
Carbon
The process where an unspecialized cell transforms into a more specialized cell type with distinct characteristics and functions.
Differentiation
Photosynthesis ___________ energy while Cellular Respiration ___________ energy.
stores, releases
When a human is having contractions, hormones are released that stimulate additional contractions. This is an example of a ________________ feedback loop.
positive
When bonds are broken energy is ____________. When bonds are formed energy is ____________.
released, stored
Carbohydrates contain the following elements:
Carbon, Hydrogen, Oxygen
Energy molecule of cells.
ATP
The reactants for photosynthesis.
CO2, water, light energy
When the human body gets cold it typically shivers to stay warm, which is known as a ________________ feedback loop.
negative
Protons are ___________, electrons are ___________, and neutrons are ___________.
positive, negative, neutral
The four macromolecules.
Carbs, lipids, proteins, nucleic acids
__________________ is the location of Photosynthesis. __________________ is the location of Cellular Respiration.
Chloroplast, mitochondria
Without oxygen __________________ respiration. With oxygen __________________ respiration.
Anaerobic, Aerobic
The organization of living things in order starting with cells.
Cells, tissues, organs, organ system, organism
Covalent bonds ___________ electrons while Ionic bonds _____________ electrons.
share, transfer
Proteins contain the following elements:
Carbon, Hydrogen, Oxygen, Nitrogen
__________________ have a genetic material enclosed by a nucleus and membrane bound organelles. __________________ have genetic material not enclosed by a nucleus and no membrane bound organelles.
Eukaryote, Prokaryote
The reactants for Cellular Respiration.
glucose, O2
List the 8 characteristics of life.
Made of cells, able to reproduce, contain genetic material (DNA), grow and develop, obtain and use energy (metabolism), respond to the environment, maintain stable internal environment (homeostasis), change over time (evolution)
molecule with uneven distribution of charges. Example water.
Name the 4 macromolecules and their monomers.
Carbohydrates- monosaccharide
Proteins- amino acids
Lipids- glycerol & fatty acids
Nucleic acids- nucleotides
When something moves from high to low concentration across the cell membrane it is called __________________ . When something moves from high to low concentration across the cell membrane with the help of a protein channel it is called __________________ . When something moves from low to high concentration across the cell membrane it is called __________________ .
Passive transport/Diffusion, Facilitated Diffusion, Active Transport
Photosynthesis takes in CO2 as a reactant while Cellular Respiration releases CO2 as a product.
