relating to, measuring, or measured by the quantity
relating to, measuring, or measured by the quality
a variable (often denoted by x ) whose variation does not depend on that of another.
value depends on that of another.
a thing that is composed of two or more separate elements
in chemistry, an organic compound is generally any chemical compound that contains carbon
What is a polymer?
A polymer is a chemical compound with molecules bonded together in long repeating chains
What are the names of the FOUR types of polymers (organic molecules) we learned about this year?
carbohydrates, lipids, proteins, and nucleic acids.
Providing the energy and regulation needed for the body.
Building Tissues and Muscles. Protein is necessary for building and repairing body tissues
The main job of DNA is to carry the code for making proteins.
The functions of lipids include storing energy, signaling, and acting as structural components of cell membranes.
ATP is for
What is the name of the process used by your body to make ATP?
In which organelle does glycolysis happen?
An atom is:
The smallest unit of an element.
Where in the atom is a proton located?
Where in the atom is an electron located?
the electron cloud
how do you find the amount of neutrons
to determine the number of neutrons in atom, we only have to subtract the number of protons from the mass number
how do you find the amount of protons
The number of protons in the nucleus of the atom is equal to the atomic number
how do you find the amount of electrons
The number of electrons in a neutral atom is equal to the number of protons.
Homeostasis is the state of steady internal conditions maintained by living things.
What type of cell will be able to maintain homeostasis the best: large or small?
Small because it has less surface area to cover.
Characteristics of animals
Animals are multicellular
Animals are heterotrophic (has to eat other things)
Animals are eukaryotic
Animals are able to reproduce asexually and sexually
Animals maintain homeostasis
a change of the form or nature of a thing or person into a completely different one, by natural or supernatural means.
Bilateral symmetry: both sides are the same
Radial symmetry: you can cut it like a pie and its the same
a rigid external covering for the body in some invertebrate animals, especially arthropods, providing both support and protection.
Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species.
Structures that are used for the same purpose but developed independently
traits that are similar to one another due to shared ancestry.
traits that are not needed anymore
the process whereby organisms not closely related (not monophyletic), independently evolve similar traits
Divergent evolution or divergent selection is the accumulation of differences between closely related species populations, leading to speciation
Natural selection is the differential survival and reproduction of individuals due to differences in phenotype.
This type prefers both extremes of a trait
The type prefers one of the extremes of a trait
a change or the process of change by which an organism or species becomes better
different kind of organisms
the changing of a structure of DNA
The father of evolution
Darwin's finches are a classical example of an adaptive radiation. Their common ancestor arrived on the Galapagos about two million years ago. During the time that has passed the Darwin's finches have evolved into 15 recognized species differing in body size, beak shape, song and feeding behaviour.Feb 11, 2015
Where Darwin went to study animals
Hardy-Weinberg equation parts
PP= Homozygous dominant
What are protons
Positively charged particles
What are neutrons
Neutral charged particles
What are electrons
Negatively charged particles
material outside the nucleus and inside
The plasma membrane
The membrane is composed of a phospholipid bilayer arranged back-to-back.
what is a species
a group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding.
trait that is present in an organism, but was absent in the last common ancestor
a branching diagram showing the cladistic relationship between a number of species.
meiosis and how it contributes to genetics
During fertilisation, 1 gamete from each parent combines to form a zygote. Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote.
The powerhouse of the cell,carry out where oxygen is used to break down food
ribosomes: made of protein and RNA, sites of protein synthesis, found free in cytoplasm and as part of rough er.
fluid-filled tubules for carrying substances
studded with ribosomes, synthesizes as proteins
functions in lipids metabolism and detoxifies drugs and pesticides
modifies and packages proteins
contain enzymes that digest worn out or non-usable materials within the cell
a network of protein structures that extend throughout the cytoplasm, provides the cell with the internal framework
paired rod shaped bodies made of microtubules
the breakdown of glucose by enzymes, releasing energy and pyruvic acid.
the mitochondrial matrix, and converts pyruvate into the two-carbon molecule acetyl CoA by removing carbon dioxide and hydrogen, through the process of decarboxylation.
provides the hydrogen and electrons needed for the electron transport chain.
electron transport chain
a series of complexes that transfer electrons from electron donors to electron acceptors via redox (both reduction and oxidation occurring simultaneously) reactions, and couples this electron transfer with the transfer of protons (H+ ions) across a membrane.
the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
The purpose of mitosis is cell regeneration, growth, and asexual reproduction
the production of gametes for sexual reproduction.
movement of materials across cell membranes.
passive cell transport
diffusion, facilitated diffusion and osmosis.
Active cell transport
Sodium-Potassium pump, Exocytosis, and Endocytosis.
net movement of molecules or atoms from a region of higher concentration to a region of lower concentration
There is more solute in the solution surrounding a cell than inside
when comparing two solutions, the solution with the lesser concentration of solutes
when the concentration of two solutions is the same
Diffusion of water through a selectively permeable membrane
A unicellular organism that lacks a nucleus and membrane bound organelles
A cell that contains a nucleus and membrane bound organelles
Diagram that shows the evolutionary relationships among a group of organisms
A phylogenetic classification system that uses shared derived characters and ancestry as the sole criterion for grouping taxa.
A family tree that shows the evolutionary relationships thought to exist among groups of organisms
bacteria vs. viruses
smaller than bacteria
no cell walls or ribosomes
requires host to replicate
have cell walls
replicate on their own
Archaebacteria, Eubacteria, Protista, Fungi, Plantae, Animalia
Chordate and craniata characteristics +
1) Vertebral column (notochord is replaced by a bony or cartilaginous column of interlocking vertebrae)
2) Endoskeleton of cartilage or bone- most also have two pairs of appendages
3) Internal organs- liver, kidneys, endocrine glands, and a heart with at least two chambers
*Liver unique to rates
*Heart, kidneys, and endocrine system are more complex than analogous structures in other taxa
o Lack backbones
o Varying Body Structures
o Make up 95-97% of all known animal species
a key for the identification of organisms based on a series of choices between alternative characters
The pH scale measures how acidic or basic a substance is. The pH scale ranges from 0 to 14. A pH of 7 is neutral
