Question: Essential genes are the set of genes thought to be critical for an organism's survival. This definition assumes the abundant availability of all relevant nutrients and the absence of environmental stress. Only a small portion of an organism's genes are essential. In bacteria, an estimated 250400 genes are essential for Escherichia coli and Bacillus subtilis, which is less than 10% of their genes. Half of these genes are orthologs in both organisms and are largely involved in protein synthesis. In the budding yeast Saccharomyces cerevisiae the number of essential genes is slightly higher, at 1000 genes (~20% of their genes). Although the number is more difficult to measure in higher eukaryotes, mice and humans are estimated to have around 2000 essential genes (~10% of their genes).
Is there an answer to this question: How many essential genes does Saccharomyces cerevisiae have?

Answer: 1000 genes

Question: The myth of a Trojan founding with Greek influence was reconciled through an elaborate genealogy (the Latin kings of Alba Longa) with the well-known legend of Rome's founding by Romulus and Remus. The most common version of the twins' story displays several aspects of hero myth. Their mother, Rhea Silvia, had been ordered by her uncle the king to remain a virgin, in order to preserve the throne he had usurped from her father. Through divine intervention, the rightful line was restored when Rhea Silvia was impregnated by the god Mars. She gave birth to twins, who were duly exposed by order of the king but saved through a series of miraculous events.
Is there an answer to this question: What type of events saved the twins of Roman myth?

Answer: miraculous

Question: From their beginnings in Sumer (now Iraq) around 3500 BC, the Mesopotamian people began to attempt to record some observations of the world with numerical data. But their observations and measurements were seemingly taken for purposes other than for elucidating scientific laws. A concrete instance of Pythagoras' law was recorded, as early as the 18th century BC: the Mesopotamian cuneiform tablet Plimpton 322 records a number of Pythagorean triplets (3,4,5) (5,12,13). ..., dated 1900 BC, possibly millennia before Pythagoras, but an abstract formulation of the Pythagorean theorem was not.
Is there an answer to this question: What was the earliest recording of Pythagoras' law?

Answer:
18th century BC
