A eukaryotic gene is most likely to be transcribed if it is located where? In a region of the genome in which the histones are methylated In a heterochromatic region of teh genome In a region of the genome in which the histones are acetylated In a region of the genome in which the histones are unmodified - Answer-In a region of the genome in which the histones are acetylated A mutant strain of E. coli is found that produces both β-galactosidase and permease constitutively. What are the M...

Activated carbon used - Calgon CPL Adsorbents and examples - mass separating agents ex: molecular sieve zeolites, activated alumina, silica gel, activated carbon Adsorption breakthrough curve - Instantaneous step change in outlet concentration from pure He to feed conc of CO2 Appears as S shaped curve due to mass and heat transfer effects and other non-ideal behaviors Characteristic velocity - velocity each concentration moves at according to equilibrium theory Concentration and velocity ...

PEQ Week 4 Test questions with 100% Correct Answers [Questions 1 and 2] You are working with a population of snails. During the mating season, you observe that individuals in the population will only mate with others of the same genotype (for example, Mm individuals will only mate with Mm individuals). There are only two alleles at this locus (M is dominant; m is recessive); you have determined that the frequency of the M allele = 0.5 and that selection acts against heterozygous individual...

[Questions 1 and 2] You are working with a population of snails. During the mating season, you observe that individuals in the population will only mate with others of the same genotype (for example, Mm individuals will only mate with Mm individuals). There are only two alleles at this locus (M is dominant; m is recessive); you have determined that the frequency of the M allele = 0.5 and that selection acts against heterozygous individuals. Assume the first generation of this population was ...

Describe how an enzyme breaks down a substrate - Answer-Substrate shape is complimentary to active site shape Substrate binds to active site Induced fit and straining of bonds forms an enzyme substrate complex Products leave active site Describe how to do the emulsion test for lipids and how a positive result would be identified - AnswerAdd ethanol Solution turns cloudy Describe the formation of a hydrogen bonds between two molecules of water. Explain why water can form these bonds - Ans...

A large population of mice (2000 individuals) lived in an area in the desert dominated by small shrubs. When the population size got too high, a small group of 6 individuals left and colonized an area adjacent to the original population's home, but the adjacent area was primarily dominated by trees instead of shrubs. There is no gene flow between the dispersers and the original population. A researcher sequenced the genomes of representative individuals from both populations and found subst...

Fixed bed adsorption - utilizes a solid mass separating agent packed inside a column to separate in a gas or liquid stream Adsorbents and examples - mass separating agents ex: molecular sieve zeolites, activated alumina, silica gel, activated carbon What is adsorbed? - CO2

((Given image)) A stem cell is fate determined once it has received the Self Renewal signal. As result, which genes are newly expressed? (Check all that apply) - -ID genes -DIV genes -DET genes ((Given)) Shown here are four ligands (M, H, K, and L) and their corresponding receptors along with three genes (U, V, and W) whose activity the receptor controls through signal transduction. The arrows indicate gene activation, the T-bars indicate gene repression. If either U or V is required to ...

In the F2 generation of a homozygous round (AA) × homozygous wrinkled (aa) cross in peas, three seeds are chosen at random. What is the probability that two seeds are round and the other is wrinkled? A) (1/4)3 B) 3(1/4)(3/4)2 C) 3(1/4)2(3/4) D) (3/4)3 - B
