1.) Human height occurs in a continuous range because it is affected by the interaction of several genes, making it a: a.) autosomal traits b.) sex-linked trait c.) polygenic trait or d.) codominant trait 2.) for an XX female to express a recessive sex-linked trait, she must have: a.) a Y chromosome, b.) an inactive allele c.) two recessive alleles d.) two dominant alleles Solution (1) c.) polygenic trait Polygenic traits are controlled by more than one gene. Human height, eye and ha...

Predict the membrane orientation of a protein that is synthesized with an N-terminal cleaved ER signal sequence followed by a stop-transfer sequence, followed by a start-transfer sequence, followed by another stop transfer sequence o N terminus in ER lumen, C terminus in cytosol Solution N terminal ER signal is a sequence that that codes for an 8-14 hydrophobic amino acid signal sequence of growing polypeptide. It targets the protein to the ER. SRP binds to SRP receptor present on cy...

For the circuit below, calculate the power absorbed by each source, and verify that the powers add to zero. Solution Power absorbed by 3A source: since this source is in parallel with the 10V source, and the current flows into the negative terminal, P = 3A * 10V = 30W Power absorbed by -4A source: since this source is in parallel with the 10V source, and the current flows into the positive terminal, P = -(-4A * 10V) = 40W Power absorbed by 2A source: split this one into...

3) Which of the following choices has the lowest potential energy? 1. Configuration (3) and Configuration (5) 2. Configuration (1) and Configuration (5) 3. Conflguration (2) 4. Configuration (2) and Configuration (3) 5. Configuration (1) and Configuration (3) 6. Configuration (1) and Configuration (2) 7. Configuration (4) ion (1) 9. Conflguration (3) 10. Conflguration (5) Solution configuration 4 since the charge is single, the potential energy is is minimum.

Explain this statement relating to microbes: Primary production is an essential process in aquatic environments, especially in lakes and oceans. Doing a project and have some ideas, but would like to broaden my paper to more details and examples please, and to make sure I am on the right track. Solution Primary producers synthesize organic compounds from inorganic raw materials like Carbon dioxide. The ones which perform primary production are called autotrophs. They form the base o...

The conductivity of intrinsic semiconductors, such as silicon and germanium, can be increased when small amounts of group 3A or group 5A elements are added, a process called doping. The resulting semiconductors are called either p-type or n-type semiconductors. Classify the type of doping condition and diagrams depicting the electron population of molecular orbital energy- level bands as p-type or n-type semiconductors. p-type semiconductors n-type semiconductors Solution Band diagr...

baking soda can be made in large quantities by the following reaction: NaCl + NH3 + CO2 + H2O = NaHCO3 + NH3Cl if 9.53 g of NaCl reacts with excesses of the other reactants and 4.13 g of NaHCO3 is isolated, what is the percent yield of the reaction? Solution moles of NaCl=0.163moles mass of NaHCO3 to be formed actually=0.163*(84)=13.7g actual mass of NaHCO3 formed=4.13g percentage yield=4.13/13.7 *100= 30.2%
