molarity and equations invest 3 CLS 8-12
what is a mol
it a unit to measure the mass of a small amount
A double helix ladder
Phenotype: observable trait. Allele: form of gene. Genotype: genes in a trait. homozygous: both genes are the same. Heterozygous: both are different
define homologous structure
a structure similar but arranged differently compared to sperate organisms due to ancestors and generational evolution
whats a pH for an acid and a base
for acid 0-6 and base 8-14
what is 1 mol of chlorine
35g
base pairing rules for DNA and RNA
DNA--- A-T G-C
RNA--- A-U G-C
give me a dominant allele and recessive allele
F, f
define analogous structure
don't have a common ancestor but they have similar structures given by environmental changes
what makes baking powder work?
what is 1 mol of H2O
18g
process of DNA turning into proteins
DNA sends messenger mRNA to ribosome to become transcribed tRNA to make amino acids to then get protein
recessive alleles will die out mostly because they bring genetic disadvantages for the organism making them get eaten more likely
what is mimicry
copy a model of an organism but is poisonous helping both the model and mimic
what are the rules to name an acid
rule 1: when anion ends in -ide change to ic and add hydro to the beginning of the name,
rule 2: when an anion ends in -ate change to -ic
rule 3: when an anion ends in -ite change to -ous
M = mol/Liter
phases for cell division
INTERPHASE: preparation for cell division PROPHASE: nuclear envelope collapse and spindle fibers emerge METAPHASE: chromosomes gather in the middle ANAPHASE: complete split between the two TELOPHASE: Nuclear envelope surrounds both chromosome groups.
why do some people have different traits such as widows peak, dimples, and others
the different traits were passed to organisms by ancestors that had these traits that somehow benefited the organism to pass down these genes.
what is Porifera best known as from description
Porifera has many pores, usually soft to touch
neutralize the reaction HC2H3O2 + NaHCO3
H2O + CO2 + NAC2H3O2
How many grams of N are in 6 moles of NH3?
84g of N
change the base pair: AUA, CGG, CAG, AUU
TAT, GCC, GTC, TAA
all males will have no hemophillia and all females will be carriers for hemophillia
name 5 phyla of the animal kingdom
Porifera, Coelenterata (Cnidaria), Platyhelminthes, Nematoda, Arthropoda, Mollusca, Echinodermata, Hemichordata, Chordata, Annelida.
