Correct Answer: B. 6th July 1967

Correct Answer: C. Producer ------------- Consumer

Explanation

The illustration that would be used to distribute the health application developed by BIK Ltd is "Producer -------------> Consumer. In this scenario, BIK Ltd, as the producer, directly provides the health application to the end consumer. This distribution model bypasses the involvement of intermediaries such as retailers, wholesalers, or agents. BIK Ltd may distribute the application through app stores, its website, or other online platforms where consumers can directly access and download the application to their devices. This direct distribution approach allows BIK Ltd to have more control over the distribution process and ensures that the health application reaches the end consumer efficiently.

Correct Answer: D. \(x^{2} + y^{2} - 8x - 10y + 21 = 0\)

Explanation

On the y-intercept, x=0. At this point, y = 5(0) - 2y = -6; y = 3, so the y- intercept has coordinates (0,3).

The equation of the circle is given as \((x-a)^{2} + (y-b)^{2} = r^{2}\), where (a,b) is the centre and r is the radius.

The radius of the circle through the y- intercept = \(\sqrt{(4-0)^{2} + (5-3)^{2}} = \sqrt{20}\)

The equation of the circle is \((x-4)^{2} + (y-5)^{2} = 20\); expanding, we have

\(x^{2} + y^{2} + 8x - 10y + 21 = 0\)

Correct Answer: B. y = 0 or 9

Explanation

\(3y^2 = 27y\\

3y^2 - 27y = 0\\

3y(y - 9) = 0\\

3y = 0 or y - 9 = 0\\

y = 0 or y = 9\\

y = 0 or 9\)

Correct Answer: A. increase in the number of young people

Explanation

A growing population is primarily determined by rates of birth, death, immigration, and emigration. Under ideal conditions, population can grow exponentially. The growth rate increases as the population gets larger. An increased number of young people indicates a fast growing population

Correct Answer: A. The linear amino acid sequence of the protein

Explanation

The primary structure of a protein is simply the linear amino acid sequence from which the protein is made. Secondary structure refers to the folding and coiling of this single strand as it interacts with itself, forming hydrogen bonds between amino acids of that strand. Alpha helices and beta-pleated sheets are two different types of secondary structures that can be formed by hydrogen-bonding between amino acids of a protein sequence that has folded over onto itself. Tertiary structure refers to the final three-dimensional structure of a single protein subunit. Quaternary structure refers to the non-covalent interactions between multiple protein subunits which come together to form a larger protein.
