Answer is option 1 / first pattern of growth.
Permissive temperature is the temperature at which auxotroph behave as wild strain. Therefore, at 37o Celsius the given auxotroph was able to grow in both minimal and complete media. While at 30o Celsius it was able to grow only in complete media.

On a certain hot day the atmospheric pressure was 1 atm and the temperature was 37oC. On this day 1 L sample of atmospheric gases was collected and analyzed. It was found to contain among other gases 9.38 x 10-3 mol of O2 gas, 2.46 x 10-8 mol of H2 gas and 1.79 x 10-4 mol of water vapor. If you put these amounts of the three gases in a sealed 1L tank at 1 atm and 37oC, will the...

Please help answer
Conditional alleles are mutant gene versions encoding proteins that can function normally at the permissive condition but are defective at the restrictive condition. One commonly used condition is temperature. Conditional alleles are especially useful to geneticists because they permit the study of essential genes. At the permissive temperature, the organism lives normally. When the organism is shifted to the non-permissive temperature, the effect of inactivating the gene can be studied. Which of the alleles shown below (mutations...

1) At physiological temperature (37OC) the osmotic pressure of blood is 7.65 atm. What concentration (% W/V) of potassium chloride (KCl, MW = 74.5) solution has the same osmotic pressure of blood? Assume the specific gravity of the solution is 1. 2)An ophthalmic (eye drop) formulation contains 100 mEq of sodium chloride (molecular weight = 58.5 g/mole).

Question 2 (1 point) Suppose you want to estimate the impact of foreign aid on growth. A classmate suggests to you that foreign aid is often given as humanitarian aid after a natural disaster. If natural disasters lead to slower growth, what would happen to your estimate of foreign aid if you did not control for natural disasters? Question 2 options: It would be positively biased. It is impossible to tell how it would be affected. It would not be...
