is larger than three solar masses it will collapse and form a black hole. A Neutron star is are around the size of a city. They are formed when giant stars die in a supernova and their cores collapse. The protons and electrons melt into each other and form neutrons. They have the mass around 1.4 times what the sun has. The other way the cycle can continue is by the Stellar Nebula turn into an average star. The average

Michaelis-Menten Kinetics: The Enzyme-Catalyzed Hydrolysis of Sucrose1 Background Of the numerous chemical reactions whose kinetics have been studied, some of the most interesting and complex are those which take place in living organisms. These reactions, when studied under non-biological conditions (lack of organisms and their various biomolecules), are often exceptionally slow: often hours or days, and sometimes even years are required before equilibrium is reached. Yet life requires seconds

AP Environmental Science D Block Summer Assignment Chapter 1 1. Exponential growth is an increase where the growth, when it is plotted, displays a logarithmic curve. Everyone living in an exponential age is a cause for concern for everyone living on the planet because resources are limited, but the rate at which the increase in population over time is accelerating. Unless we can maximize the use of our resources and find a way to increase our resources substantially and sustainably, we will not have
