polysaccharides
They are long chains of sugar units They are polymers of monosaccharides, Complex carbohydrates
enzymes structure roles signaling
what do amion acid do
carbohydrates, lipids, proteins, nucleic acids
what are the four large categories in cells
Domain of unicellular prokaryotes that have cell walls that do not contain peptidoglycan
archaea
what are the three domain of life
Bacteria, Archaea, Eukarya
Has a nucleus, have organelles, larger
Eukaryotic
polar
region or poles of the molecule have different charges
Monosaccharides
what are simple sugars and are the main fuel that cells use for cellular work
single-celled organisms that lack a nucleus; prokaryotes
bacteria
Domain of all organisms whose cells have nuclei, including protists, plants, fungi, and animals
Eukarya
RNA
agcu, singal strand
Matter
Anything that has mass and takes up space
ionic bond
what are formed between oppositely charged ions
Solvant
The dissolving agent is called the
nucleic acids
They provide the directions for building proteins, are information storage molecules
use general principles to predict observation based on hupotheses
deductive reasoning
Lipids
They do not mix with water Examples: fats and steroids, and hydrophobic
Single-celled, such as most bacteria and protists Multicelled, such as plants, animals, and most fungi
Organisms are either
Base
A compound that accepts H+ ions and removes them from solution
moderate temperature, floating ice, cohison
stuff water can do
A central carbon atom bonded to four covalent partners A side group that is variable among all 20
what does a amion acid consit of
Heat
the amount of energy associated with the movement of the atoms and molecules in a body of matter
all living things are composed of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells.
cell theory of life
Protein
is a polymer constructed from amino acid monomers, perform most of the tasks the body needs to function They are the most elaborate of life's molecules
what are some properties of life
Reproduction,Capable of growth,Metabolize utilization of energy regulation,Comprised of at least one cell,
chemical reaction
Cells constantly rearrange molecules by breaking existing chemical bonds and forming new ones
Temperature
measures the intensity of heat
covalent bond
what forms when two atoms share one or more pairs of outer-shell electrons
steroids
Cholesterol is the "" from which your body produces other, The carbon skeleton is bent to form four fused rings
Oxygen (O), Nitrogen (N), Carbon (C), and Hydrogen (H)
what are for the 4 elemonts for humans life
does not have nucleus, no organelles, smaller
Prokaryotic
hydrogen bond
The polarity of water results in weak electrical attractions between neighboring water molecules
Acid
A chemical compound that donates H+ ions to solutions
DNA
agct, double strand
DNA, deoxyribonucleic acid RNA, ribonucleic acid
What are the two types of nucleic acids?
combine observations to discover general principles
inductive reasoning
Solute
The dissolved substance is called the
polymers
what are made by stringing together many smaller molecules called monomers
Carbohydrates
what are Small sugar molecules in soft drinks Long starch molecules in pasta and potatoes
Cohesion
Water molecules stick together as a result of hydrogen bonding
central core
where is the atoms nuclues
Atoms
is the smallest unit of matter that still retains the properties of an elemen
solid, liquid, gas
three states of matter
a-t, g-c
base pairs
peptide bond
is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water (H2O)
amion acid
All proteins are constructed from a common set of 20 kinds
Cell Structure & Function. Stability & Homeostasis. Reproduction & Inheritance. Evolution. Interdependence of Organisms. Matter, Energy, & Organization.
themes of life
What is biology?
The study of life
92
How many elements occur naturally?
Solution
what is is a liquid consisting of two or more substances evenly mixed
