Article: The growth, development, and reproduction of organisms relies on cell division, or the process by which a single cell divides into two usually identical daughter cells. This requires first making a duplicate copy of every gene in the genome in a process called DNA replication.:5.2 The copies are made by specialized enzymes known as DNA polymerases, which "read" one strand of the double-helical DNA, known as the template strand, and synthesize a new complementary strand. Because the DNA double helix is held together by base pairing, the sequence of one strand completely specifies the sequence of its complement; hence only one strand needs to be read by the enzyme to produce a faithful copy. The process of DNA replication is semiconservative; that is, the copy of the genome inherited by each daughter cell contains one original and one newly synthesized strand of DNA.:5.2

Question: Why does the sequence of one strand completely specify the sequence of its complement?
Ans: Because the DNA double helix is held together by base pairing

Article: The Ministry of Defence is one of the United Kingdom's largest landowners, owning 227,300 hectares of land and foreshore (either freehold or leasehold) at April 2014, which was valued at "about 20 billion". The MoD also has "rights of access" to a further 222,000 hectares. In total, this is about 1.8% of the UK land mass. The total annual cost to support the defence estate is "in excess of 3.3 billion".

Question: How much land is owned by the MoD?
Ans: 227,300 hectares

Article: Anthropologists maintain that hunter/gatherers don't have permanent leaders; instead, the person taking the initiative at any one time depends on the task being performed. In addition to social and economic equality in hunter-gatherer societies, there is often, though not always, sexual parity as well. Hunter-gatherers are often grouped together based on kinship and band (or tribe) membership. Postmarital residence among hunter-gatherers tends to be matrilocal, at least initially. Young mothers can enjoy childcare support from their own mothers, who continue living nearby in the same camp. The systems of kinship and descent among human hunter-gatherers were relatively flexible, although there is evidence that early human kinship in general tended to be matrilineal.

Question: What is the kinship and decent system among hunter-gatherers?
Ans: matrilineal

Article: The verbs of most aspect pairs differ in one of two ways: by prefix or by suffix. In prefix pairs, the perfective verb has an added prefixfor example, the imperfective psat (to write, to be writing) compared with the perfective napsat (to write down, to finish writing). The most common prefixes are na-, o-, po-, s-, u-, vy-, z- and za-. In suffix pairs, a different infinitive ending is added to the perfective stem; for example, the perfective verbs koupit (to buy) and prodat (to sell) have the imperfective forms kupovat and prodavat. Imperfective verbs may undergo further morphology to make other imperfective verbs (iterative and frequentative forms), denoting repeated or regular action. The verb jit (to go) has the iterative form chodit (to go repeatedly) and the frequentative form chodivat (to go regularly).

Question: What is added to the ending in suffix pairs?
Ans:
different infinitive ending
