Problem: Pesticide:

Pesticides are substances meant for attracting, seducing, and then destroying any pest. They are a class of biocide. The most common use of pesticides is as plant protection products (also known as crop protection products), which in general protect plants from damaging influences such as weeds, fungi, or insects. This use of pesticides is so common that the term pesticide is often treated as synonymous with plant protection product, although it is in fact a broader term, as pesticides are also used for non-agricultural purposes. The term pesticide includes all of the following: herbicide, insecticide, insect growth regulator, nematicide, termiticide, molluscicide, piscicide, avicide, rodenticide, predacide, bactericide, insect repellent, animal repellent, antimicrobial, fungicide, disinfectant (antimicrobial), and sanitizer.

What are examples of the way a plant protects itself against pests?

Problem: During the Eocene (56 million years ago - 33.9 million years ago), the continents continued to drift toward their present positions. At the beginning of the period, Australia and Antarctica remained connected, and warm equatorial currents mixed with colder Antarctic waters, distributing the heat around the world and keeping global temperatures high. But when Australia split from the southern continent around 45 Ma, the warm equatorial currents were deflected away from Antarctica, and an isolated cold water channel developed between the two continents. The Antarctic region cooled down, and the ocean surrounding Antarctica began to freeze, sending cold water and ice floes north, reinforcing the cooling. The present pattern of ice ages began about 40 million years ago.[citation needed]
What reached their final positions during the Eocene?

The first successful light bulb filaments were made of carbon (from carbonized paper or bamboo). Early carbon filaments had a negative temperature coefficient of resistance — as they got hotter, their electrical resistance decreased. This made the lamp sensitive to fluctuations in the power supply, since a small increase of voltage would cause the filament to heat up, reducing its resistance and causing it to draw even more power and heat even further. In the "flashing" process, carbon filaments were heated by current passing through them while in an evacuated vessel containing hydrocarbon vapor (usually gasoline). The carbon deposited on the filament by this treatment improved the uniformity and strength of filaments as well as their efficiency. A metallized or "graphitized" filament was first heated in a high-temperature oven before flashing and lamp assembly. This transformed the carbon into graphite which further strengthened and smoothed the filament. This also changed the filament to have a positive temperature coefficient, like a metallic conductor, and helped stabilize the lamp's power consumption, temperature and light output against minor variations in supply voltage.
What were negative effects of the flashing process?
A: unanswerable


Context and question: European colonialism in the Sahara began in the 19th century. France conquered the regency of Algiers from the Ottomans in 1830, and French rule spread south from Algeria and eastwards from Senegal into the upper Niger to include present-day Algeria, Chad, Mali then French Sudan including Timbuktu, Mauritania, Morocco (1912), Niger, and Tunisia (1881). By the beginning of the 20th century, the trans-Saharan trade had clearly declined because goods were moved through more modern and efficient means, such as airplanes, rather than across the desert.
What year did France conquer Niger?

Question: For many years Arsenal's away colours were white shirts and either black or white shorts. In the 1969–70 season, Arsenal introduced an away kit of yellow shirts with blue shorts. This kit was worn in the 1971 FA Cup Final as Arsenal beat Liverpool to secure the double for the first time in their history. Arsenal reached the FA Cup final again the following year wearing the red and white home strip and were beaten by Leeds United. Arsenal then competed in three consecutive FA Cup finals between 1978 and 1980 wearing their "lucky" yellow and blue strip, which remained the club's away strip until the release of a green and navy away kit in 1982–83. The following season, Arsenal returned to the yellow and blue scheme, albeit with a darker shade of blue than before.
Is there an answer to this question: What color sleeves did Arsenal have in the 1969-70 season?

Answer: unanswerable

According to the Sunni scholar Ibn ʻAsākir in the 12th century, there were opportunities for female education in the medieval Islamic world, writing that women could study, earn ijazahs (academic degrees), and qualify as scholars and teachers. This was especially the case for learned and scholarly families, who wanted to ensure the highest possible education for both their sons and daughters. Ibn ʻAsakir had himself studied under 80 different female teachers in his time. Female education in the Islamic world was inspired by Muhammad's wives, such as Khadijah, a successful businesswoman. According to a hadith attributed to Muhammad, he praised the women of Medina because of their desire for religious knowledge:
