radial symetry
symetry around a central axis(more than two planes produce mirored halves)symetry goes around like a starfish.found in many cnidarians and echinoderms and sponges.
bilateral symetry
one sagittal plane devides into two mirrored halves.such
as humans, have left and right sides that are mirror images of each other.As you can
see in Figure 4, bilaterally symmetrical animals also have diff erent dorsal (upper) and
ventral (lower) surfaces as well as an anterior (front) and posterior (back) end.
BINOMIAL NOMENCLATURE
The system of naming, which literally means: Two name naming system.Names must either be underlined or italicized
Genus capitalized, species is lowercase
species
organism that can interbreed with one another ,and produce fertile offspring in nature.
Hybrids
When two organisms of different species interbreed, the offspring is called a HYBRID
Which two groups are used for an organism’s scientific name?
Genus and species
related if
if they have the same Genus the genus is like the last name even though the genus is always capitalized.
Which of the following pairs is MOST closely related?
Acer rubrum & Acer saccharum
Acer rubrum & Chenopodium rubrum
Acer rubrum & Acer saccharum because they have the same genus

lytic cycles
is when an impatiant virus takesover a cells machinery to start making copies of the viruses genetic material which can be rna or dna and also the viruses protiens to make their protien coat and they will self assemble to form fully functional viruses and since it makes more and more of them it will force the cell to break open and once its breaks open all the viruses are released into the envorment to hack into nearby cells to create more armys.
lysogenic cycles
is when the viruses sneaks into the cell to keep the host alive,and it combines with the host genetic information so that the host cant tell that its there and then the bacteria continues replicating and the virus follows the bactaria when it replicates and then the virus is np longer quite so that it makes copies of themselves.
An example of a lytic cycle
T4, which infects E. coli found in the human intestinal tract.
an better explanation of lytic cycle
With lytic phages, bacterial cells are broken open (lysed) and destroyed after immediate replication of the virion. As soon as the cell is destroyed, the phage progeny can find new hosts to infect.
an example of lysogenic cylce
An example of a bacteriophage known to follow the lysogenic cycle and the lytic cycle is the phage lambda of E. coli.
a better explanation of a lysogenic cylce
As the lysogenic cycle allows the host cell to continue to survive and reproduce, the virus is reproduced in all of the cell’s offspring.
