Two technicians were discussing hybrid organic acid technology​ (HOAT) coolants. Technician A stated that hybrid organic acid te

chnology​ (HOAT) coolants use organic acid salts​ (carboxylates) that are abrasive to water pumps. Technician B stated that the pH of hybrid organic acid technology​ (HOAT) coolants is usually below 7. Which of the following about the scenario is​ true?
A. Only technician​ A's assessment is accurate.
B. Neither technician​ A's nor​ B's assessment is accurate.
C. Both technician​ A's and​ B's assessments are accurate.

Answer:

B. Neither technician​ A's nor​ B's assessment is accurate.

Explanation:

Technician A is wrong because HOAT use organic acid with a low silicate inorganic corrosion inhibitors and it doesn't damage water pump as it contains azole additive which is a copper corrosion inhibitor.

Technician B is wrong because all coolants operate at neutral or basic pH range (pH equal to or greater than 7).

A dihybrid cross is performed between plants that differ in two Mendelian traits: Stem length (T or t) and flower coloration (R
Dahasolnce [82]

Answer:

A. 3/16

Explanation:

The four possible outcomes for Stem length are:

Tt, tT, TT and tt.

The dominant trait (tall stems) will manifest itself in 3 out of 4 outcomes, so its ratio is 3/4.

The four possible outcomes for flower coloration are:

Rr, rR, RR and rr.

The non-dominant trait (white flowers) will manifest itself in 1 out of 4 outcomes, so its ratio is 1/4.

Multiplying both ratios gives us the ratio of offspring that have tall stems and white flowers:

\frac{3}{4}*\frac{1}{4}=\frac{3}{16}

Therefore, the answer is A. 3/16
