Answer #1

Yes by the help of the CLUSTAL W multiple sequence alignment program it is possible to compare DNA sequences for many proteins in different organisms online. the information is stored in TaxMan database.

Competitive exclusion principle also called as Gause's law, states that " two species competing for the same limited resource cannot coexist at constant population values".

This means if there are two species say A and B species A has the slightest advantage over species B, then species A will dominate over species B in that ecological space in the long term. Thus this will lead either to the extinction of the weaker species B or an evolutionary or behavioral shift of the species B towards a different ecological niche. Thus in nutshell "complete competitors can't coexist".

Neutron stars are one of the possible “final states” of a star. The idea is that for a sufficiently massive star, the gravitational pressure is enough to overcome the outward pressure (that comes from essentially the Pauli exclusion principle) that keeps fermions from coinciding with each other. Part A) According to quantum statistics, the OUTWARD pressure of a (neutron) fermionic gas is given by P=[(3.9?^2)/(2m)](N/V)^(5/3), where m is the mass of a neutron, and N/V is the number density of...

3D printing started in the early 1980s. There are many different processes and many different patents, so it is difficult to say who actually invented it or first brought 3D printing to the market. Let’s suppose we could. Consider the first 3D printing company, which we’ll call 3DisUs, selling 3D printers to industries to use to create intricate plastic parts that might otherwise take much more money to create. A. Suppose 3DisUs commissioned a market research company to survey a...
