The normal approximation to the binomial distribution is given as:

X ~ B(n, p), then it is approximated to a normal distribution such that,

X ~ N(np, np(1-p)) where n is the number of trials, p is the probability of success, and (1-p) is the probability of failure.

The null hypothesis is given as H₀: The median percent of impurities in this brand of jam is 25%.

The alternative hypothesis is given as H₁: The median percent of impurities is not 25%.

The median percent of impurities is given as : (1/2) * (16 + 1) = 8.5.

The following are the number of times the data is above and below 8.5: 2.4 + 2.3 + 3.1 + 2.2 + 2.3 + 3.6 = 16.9 > 8.5. Thus, we have 6 values above the median.

1.2 + 1.0 + 1.7 + 1.9 + 1.6 + 2.3 = 10.7 > 8.5. Thus, we have 6 values below the median.

The total number of signs of observations above the median is given as m₁ = 6.

The total number of signs of observations below the median is given as m₂ = 6

The total number of observations is given as n = 16.

The Z test statistic is given as Z = [min(m₁, m₂) - 0.5]/[√(n/2)] = [min(6, 6) - 0.5]/[√(16/2)]≈ 1.5

Using a normal distribution table, the critical value for α = 0.05 is given as zα/2 = 1.96.

Since |Z| = |1.5| < |1.96|, we accept the null hypothesis that the median percent of impurities in this brand of jam is 25%. Therefore, the sign test at the 0.05 level of significance is not significant enough to reject the null hypothesis.

The correct answer about mRNA is (d). The researcher will find that the molecule is digested by enzymes because it is not protected at the 5' end.

The cap structure is a methylated guanine that links to the mRNA via an unusual 5' to 5' triphosphate bond, while the poly-A tail is a series of adenines that are added to the 3' end of an mRNA molecule. The cap and tail are vital for ensuring mRNA stability, mRNA nuclear export, and translation initiation into proteins. When the cap and tail are removed, the mRNA becomes vulnerable to RNases (ribonucleases), which are enzymes that digest RNA.

In summary, the mRNA will not be translated by a ribosome because it lacks a 5' cap, which is required for translation initiation, and it will be rapidly degraded by enzymes because it lacks a poly-A tail.

The researcher would thus expect the mRNA to be destroyed quickly.

The correct answer to the given question is vitamin E works in the lipid membrane and vitamin C works in the aqueous solution of the cell.

So, the answer is C.

Vitamin E is a fat-soluble nutrient that serves as an antioxidant in the body. Vitamin E, like all antioxidants, aids in the body's battle against harmful, unstable particles known as free radicals. Furthermore, vitamin E has been linked to a variety of other health benefits, such as reduced cholesterol levels and reduced skin aging. Vitamin E is abundant in nuts, seeds, and vegetable oils.

Vitamin C, also known as ascorbic acid, is a water-soluble vitamin that acts as an antioxidant in the body. Vitamin C aids in the protection of cells against oxidative stress, which is caused by free radicals. Vitamin C also helps to regenerate other antioxidants in the body, such as vitamin E. Vitamin C is found in citrus fruits, strawberries, kiwi fruit, bell peppers, broccoli, spinach, and other vegetables.

A lipid membrane is a double layer of lipids, or fat molecules, that surrounds a cell. The lipid bilayer serves as a barrier that allows only certain molecules to enter and exit the cell. The lipid membrane, for example, prevents toxic substances from entering the cell while allowing necessary nutrients to enter the cell for survival.
