There is a strong relationship between the properties of wood and the properties of the particular tree that yielded it. The density of wood varies with species. The density of a wood correlates with its strength (mechanical properties). For example, mahogany is a medium-dense hardwood that is excellent for fine furniture crafting, whereas balsa is light, making it useful for model building. One of the densest woods is black ironwood.
What property of wood has a correlation to its density?
****
The answer: strength

In all organisms, two steps are required to read the information encoded in a gene's DNA and produce the protein it specifies. First, the gene's DNA is transcribed to messenger RNA (mRNA).:6.1 Second, that mRNA is translated to protein.:6.2 RNA-coding genes must still go through the first step, but are not translated into protein. The process of producing a biologically functional molecule of either RNA or protein is called gene expression, and the resulting molecule is called a gene product.
What is the process of producing a biologically functional molecule of either RNA or protein called?
****
The answer: gene expression

Frustrated by the wasted effort, and with demands for action from their citizens, the allied force decided to attack the center of Russian strength in the Black Sea at Sevastopol on the Crimean peninsula. After extended preparations, the forces landed on the peninsula in September 1854 and fought their way to a point south of Sevastopol after a series of successful battles. The Russians counterattacked on 25 October in what became the Battle of Balaclava and were repulsed, but at the cost of seriously depleting the British Army forces. A second counterattack, ordered personally by Nicholas, was defeated by Omar Pasha. The front settled into a siege and led to horrible conditions for troops on both sides. Smaller actions were carried out in the Baltic, the Caucasus, the White Sea and in the North Pacific.
The Crimean peninsula is located in what city?
****
The answer: Sevastopol

The original early 19th-century interior designs, many of which survive, include widespread use of brightly coloured scagliola and blue and pink lapis, on the advice of Sir Charles Long. King Edward VII oversaw a partial redecoration in a Belle Epoque cream and gold colour scheme. Many smaller reception rooms are furnished in the Chinese regency style with furniture and fittings brought from the Royal Pavilion at Brighton and from Carlton House. The palace has 775 rooms, and the garden is the largest private garden in London. The state rooms, used for official and state entertaining, are open to the public each year for most of August and September, and on selected days in winter and spring.
Who suggested the use of brightly coloured scagliola and blue and pink lapis?
****
The answer:
Sir Charles Long
