Leonardo Fibonacci wrote about recreational mathematics, some of which involved number series such as the Fibonacci series that he is credited with discovering. * * * * * It is said that he was modelling rabbit population when he came up with the sequence that now bears his name. The rules are simple: 1. Rabbits that are one year old are juveniles and do not breed. 2. Each pair of rabbits aged two or more produce a pair of rabbit each year (forever!). 3. No rabbits ever die (what?). The whole process could apply to periods shorter than a year. Year 1: One pair of rabbits aged 0. Year 2: One pair of juvenile rabbits. Year 3: One pair of mature rabbits + One pair offspring aged 0 = 2 pairs Year 4: One pair mature + One pair offspring age 0 + One pair juvenile = 3 pairs Year 5: Two pair mature + One pair offspring age 0 + One pair juvenile + one pair offspring age 0 (from the newly mature) = 5 and so on. This model is a pretty poor descriptor for a rabbit population so I suspect it is not true. But makes an interesting exercise for young minds.
As much as the sentimental value of which you pair to it.
sometimes... usually poor Victorian families would have ONE pair of shoes which the whole family would wear E.G. they would take it in turns. If they did have a pair of their own shoes they would most probably home made.
They gave a breeding pair of Pandas, which were housed in the National Zoo in Washington, DC.
the are multiple forms of this question and there are different answers if it says Louis XVI and thousands of others are arrested and executed, Napoleon declares himself emperor of France. Then the answer is (1) The National Constituent Assembly proposes a new constitution. (2) French leaders end the Reign of Terror and condemn its leader
The pair of ideas central to the scientific revolution were empiricism, the idea that knowledge should be based on observation and experience, and skepticism, the questioning of accepted beliefs and ideas in order to seek truth through logical reasoning and evidence.
The pair of ideas central to the scientific revolution was the use of empirical observation and experimentation to understand the natural world, along with the idea that natural phenomena could be explained through natural laws and principles rather than divine intervention. This shift in thinking laid the foundation for modern scientific inquiry and method.
The central pair of ideas in the Scientific Revolution were empiricism, which emphasized the importance of direct observation and experimentation in forming scientific knowledge, and the heliocentric model of the universe, which proposed that the Earth and other planets revolved around the Sun. These concepts challenged traditional views rooted in religious and philosophical beliefs, paving the way for a new era of scientific inquiry and discovery.
The two central ideas of the scientific revolution were empiricism, which emphasizes observation and experimentation to gain knowledge, and the heliocentric theory, which proposed that the Earth and other planets revolve around the Sun rather than the geocentric model that had been accepted for centuries.
Yes.
A lone pair apex refers to the central atom in a molecule that possesses a lone pair of electrons. These electrons are not participating in bonding with other atoms and instead are localized on the central atom. The lone pair apex influences the geometry and reactivity of the molecule.
There is one lone pair of electrons on the central atom (nitrogen) in ammonia.

The question is not answerable. There is NO central atom in C2H2 (ethyn) and there's NO lone pair. All electrons are covalently shared in pairs: three pairs between C and C, one single pair in each C and H bond.
