Question: Bacteria (i/bktri/; singular: bacterium) constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria have a number of shapes, ranging from spheres to rods and spirals. Bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit soil, water, acidic hot springs, radioactive waste, and the deep portions of Earth's crust. Bacteria also live in symbiotic and parasitic relationships with plants and animals. They are also known to have flourished in manned spacecraft.

There are typically 40 million bacterial cells in a gram of soil and a million bacterial cells in a millilitre of fresh water. There are approximately 51030 bacteria on Earth, forming a biomass which exceeds that of all plants and animals. Bacteria are vital in recycling nutrients, with many of the stages in nutrient cycles dependent on these organisms, such as the fixation of nitrogen from the atmosphere and putrefaction. In the biological communities surrounding hydrothermal vents and cold seeps, bacteria provide the nutrients needed to sustain life by converting dissolved compounds, such as hydrogen sulphide and methane, to energy. On 17 March 2013, researchers reported data that suggested bacterial life forms thrive in the Mariana Trench, which with a depth of up to 11 kilometres is the deepest part of the Earth's oceans. Other researchers reported related studies that microbes thrive inside rocks up to 580 metres below the sea floor under 2.6 kilometres of ocean off the coast of the northwestern United States. According to one of the researchers, "You can find microbes everywhere they're extremely adaptable to conditions, and survive wherever they are." 1. What is the singular tense of bacteria?

Question: Hans said to his friend Kurt, "I'm going to take my car to drive to London." Kurt said, "Driving to London is very hard. You aren't going to find your hotel." But Hans was not afraid. He drove to Calais, put his car on the ship, took it off at Dover, and drove to London. He stopped near the city and looked at his map. Then he drove into London, but he did not find his hotel. He drove round and round for an hour, and then he stopped and got out of his car. A taxi came, and Hans stopped it. "Take me to the Brussels Hotel," he said. But he did not get into the taxi: he got back into his car. The taxi man laughed, but then he drove to the Brussels Hotel, and Hans followed him in his car. They reached the hotel in two minutes. ,. 1. Who is Kurt?

Question: In mathematics, a group is an algebraic structure consisting of a set of elements equipped with an operation that combines any two elements to form a third element. The operation satisfies four conditions called the group axioms, namely closure, associativity, identity and invertibility. One of the most familiar examples of a group is the set of integers together with the addition operation, but the abstract formalization of the group axioms, detached as it is from the concrete nature of any particular group and its operation, applies much more widely. It allows entities with highly diverse mathematical origins in abstract algebra and beyond to be handled in a flexible way while retaining their essential structural aspects. The ubiquity of groups in numerous areas within and outside mathematics makes them a central organizing principle of contemporary mathematics.

Groups share a fundamental kinship with the notion of symmetry. For example, a symmetry group encodes symmetry features of a geometrical object: the group consists of the set of transformations that leave the object unchanged and the operation of combining two such transformations by performing one after the other. Lie groups are the symmetry groups used in the Standard Model of particle physics; Point groups are used to help understand symmetry phenomena in molecular chemistry; and Poincare groups can express the physical symmetry underlying special relativity. 1. In math, what is a group called?
2. What pair is a group made of?
3. Does it merge any two to form a third?
4. How many conditions does it meet?
5. What are the four called?
6. Groups share a closeness with the notion of what?
7. What does a symmetry group encode features of?
8. What are point groups used to help figure out?
9. The ubiquity of groups in few areas?
10. What are group axioms?
11. Is it detached from the group? Provide a numbered list of answers.
