question:
Certain genera of Gram-positive bacteria, such as Bacillus, Clostridium, Sporohalobacter, Anaerobacter, and Heliobacterium, can form highly resistant, dormant structures called endospores. In almost all cases, one endospore is formed and this is not a reproductive process, although Anaerobacter can make up to seven endospores in a single cell. Endospores have a central core of cytoplasm containing DNA and ribosomes surrounded by a cortex layer and protected by an impermeable and rigid coat. Dipicolinic acid is a chemical compound that composes 5% to 15% of the dry weight of bacterial spores. It is implicated as responsible for the heat resistance of the endospore.
answer:
What are highly resistant dormant structures of certain gram-positive bacteria called?

question:
In addition to those actors who have headlined the series, others have portrayed versions of the Doctor in guest roles. Notably, in 2013, John Hurt guest-starred as a hitherto unknown incarnation of the Doctor known as the War Doctor in the run-up to the show's 50th anniversary special "The Day of the Doctor". He is shown in mini-episode "The Night of the Doctor" to have been retroactively inserted into the show's fictional chronology between McGann and Eccleston's Doctors, although his introduction was written so as not to disturb the established numerical naming of the Doctors. Another example is from the 1986 serial The Trial of a Time Lord, where Michael Jayston portrayed the Valeyard, who is described as an amalgamation of the darker sides of the Doctor's nature, somewhere between his twelfth and final incarnation.
answer:
Who played the War Doctor?

question:
From the late 18th century to the mid-19th century, large areas of India were annexed by the British East India Company of British Empire. Dissatisfaction with Company rule led to the Indian Rebellion of 1857, after which the British provinces of India were directly administered by the British Crown and witnessed a period of both rapid development of infrastructure and economic stagnation. During the first half of the 20th century, a nationwide struggle for independence was launched with the leading party involved being the Indian National Congress which was later joined by other organizations. The subcontinent gained independence from the United Kingdom in 1947, after the British provinces were partitioned into the dominions of India and Pakistan and the princely states all acceded to one of the new states.
answer:
What company annexed large areas of India in the 18th and 19th centuries?
