The correct answer is option C, the concentration of the hydroxide ion is greater than the concentration of the hydronium ion
Reason -
An acidic solution has an ability to contribute hydrogen ion. Here a hydronium ion (H3O+) has an extra H+ ion along with a water molecule. Thus presence of hydronium ion in larger amount than the hydroxide ion would make the solution acidic. Thus, the concentration of hydroxide ion should be less than the hydronium ion to make the solution a basic solution.
Answer:
1. Number of DNA molecules after 30 Cycles of PCR = 1.02 x 10^9
2. No. of mutant DNA molecules = 1.07 x 10^9
Explanation:
1. You just have to take the exponential of 2 to the power of the number of PCR cycles (2^n)
2. All copies were normal at cycle 10 that are about 1024 copies. At cycle 11 single point error, all further copies are mutated.
Answer:
Groundwater is all the water that has penetrated the earth's surface and is found in one of two soil layers. The one nearest the surface is the <u>"zone of aeration"</u>, where gaps between soil are filled with both air and water. Below this layer is the "zone of saturation", where the gaps are filled with water.
Explanation:
Groundwater is the water found underground in the cracks and spaces in soil, sand and rock. It is stored in and moves slowly through geologic formations of soil, sand and rocks called aquifers.
