Correct Answer: A. 2

Correct Answer: A. emulate his good gesture

Correct Answer: A. 4/16

Explanation

Since the offspring receives one allele from each parent, crossing a purebred dominant organism with a purebred recessive organism (PPQQ x ppqq) will always result in a hybridized offspring (PpQq). Thus, Flower 1's genotype is PpQq. Also remember that a recessive phenotype always indicates double recessive alleles for that trait. And so, crossing Flower 1 with a white, short-stemmed flower will result in the cross PpQq x ppqq. The next step is to draw a 4x4 Punnett square, as seen in the diagram. The desired genotype for this question is ppqq (recessive phenotype), and from the Punnett square you will be able to see that 4/16 of the squares will carry this specific genotype.

Correct Answer: C. rod

Correct Answer: B) 1.0cm

Explanation

An important concept in chromatography is the \(r_f\)-value, which stands for the retention factor. The \(r_f\)-value is a ratio that compares the distance traveled by a compound to the distance traveled by the solvent front. It is calculated using the following formula:

In this question, you are given the \(r_f\)-value of the compound (0.505) and the distance the compound traveled (10 cm, as it moved halfway up the 20 cm long plate). You are asked to find the distance of the solvent front from the top of the plate upon elution.

First, let's find the distance traveled by the solvent front. We can rearrange the formula for the \(r_f\)-value to solve for the distance traveled by the solvent front:

Substitute the given values:

Now, to find the distance of the solvent front from the top of the plate, subtract the distance traveled by the solvent front (19.8 cm) from the total length of the plate (20 cm):

Therefore, the correct answer isOption B: 1.0 cm.

Explanation

(a) Devaluation means a fall in the exchange value of a country's currency in relation to the currencies of other countries. It is the reduction of the value of a country's currency in relations to the currencies of other nations.

(b) Devaluation will improve the balance of payment of a country under the following conditions:

(i) The elasticity of demand for imports must be elastic. Increase in prices of imports, as a result of devaluation will reduce the demand for import.

(ii) The country's export must have elastic demand in other countries.

(iii) Other nations should not devalue their own currencies

(iv) For devaluation to be effective, there must be no increase in wages and other incomes.

Correct Answer: B. planktons

Correct Answer: C. 4

Explanation

\(\log_{10}\)(6x - 4) - \(\log_{10}\)2 = 1

\(\log_{10}\)(6x - 4) - \(\log_{10}\)2 = \(\log_{10}\)10

\(\log_{10}\)\(\frac{6x - 4}{2}\) - \(\log_{10}\)10

\(\frac{6x - 4}{2}\) = 10

6x - 4 = 2 x 10

= 20

6x = 20 + 4

6x = 20

x = \(\frac{24}{6}\)

x = 4
