A strong open followed by strong close will allow trader to do what? - Answer Buy on a pullback after next open. A weak close after strong open will allow trader to do what? - Answer Sell short near following open Highs and lows occur where during the day? - Answer Most often at the open Large opening gaps imply what about the day? - Answer Greater volatility Pivot point calculation - Answer P = (H+L+C)/3 R1 = 2P-L S1 = 2P-H R2 = (P-S1)+R1 S2 = P-(R1-S1) Weaknesses of Candlest...

change from gen to gen via selection of heritable traits evidence for evolution - Answer - fossils - extinction - transitional forms - vestigial traits why is the myth about evolution being goal oriented false? - Answer species do not adapt because they "want" or "need" traits; they adapt them because an ancestor with that triat just so happened to reproduce sooner or more successfully than others why is the myth that evolution is a hierachy false? - Answer evolution is more a ne...

what vector(or agent in the environment) transmits malaria? - Answer- the anopheles mosquito at the microscopic level, we can see that the phenotype of round versus wrinkled seed: - Answer- heterozygotes have 50% of the protein as homozygote domains how many letters (nucleotides) of the genetic code are needed to specify a specific amino acid? - Answer- 3 Hippocrates first explained heredity by suggesting that "seeds" are produced by the body and then collected and transmitted at the ...

Why might Pasteur's experiment be inconclusive? - Answer The swan-necked flask broth may not support cell growth, or the broth was poisoned. Experiment did not confirm hypothesis that all cells come from pre-existing cells Why are replicates important in experiments? - Answer To ensure that results were not achieved by random chance What is the definition of a replicate? - Answer Unit that shares a common thing (4 mice in one cage = 1 replicate) What does the law of succession suggest?...

Interpret this statement: Extinct fossil species are typically succeeded by similar living species - Answer Extinct and living forms represent ancestors and descendants Which is an example of developmental homology a) gene content b) similar organismal structures c)vestigial traits d) similar embryonic traits - Answer d) Which is not one of Darwin's 4 Postulates: a) Individuals in a population vary in their traits b) These differences are not heritable; they are not passed onto offs...

How does mutation lead to gene pools changing? - Answer alleles mutate into another form; important for variation How does natural selection lead to gene pools changing? - Answer not all individuals have ability to produce offspring; "survival of the fittest" How does non-random mating lead to gene pools changing? - Answer mating based on proximity and preference; not all individuals have equal chance of finding mate How does gene flow lead to gene pools changing? - Answer migration; ...
