What is the electron configuration for Calcium?
In order to find the electron configuration for Calcium, we need to know how many electrons are in Ca. Elemental Ca has an atomic number of 20, so there are 20 electrons in one atom. Based on the fourth row location of the element, we know that it must possess electrons in the 1-4 rows of the s block and the 1-3 rows of the p block: Ca : 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2

What process does this equation represent and where does it take place in the cell: C6H12O6 + O2 --> CO2 + H2O ?
This equation represents the conversion of glucose and oxygen into water and carbon dioxide. In biology the process of converting glucose into usable energy (ATP) is called cellular respiration. Cellular respiration occurs in the mitochondria of the cell.

What are the seven characteristics of life?
There are seven properties used to characterize living things. These characteristics include: 1) Organization --> living things are organized into tiny building blocks called cells, which can be organized into larger units like tissues 2) Metabolism --> living organisms can carry out biochemical reactions to process energy 3) Homeostasis --> living organisms can regulate their internal environment 4) Growth --> the cells in an organism can grow larger and cells can accumulate through division 5) Reproduction --> living things can reproduce themselves to generate new organisms 6) Response --> organisms respond to stimuli or changes in the environment 7) Evolution --> the genetic makeup of a population will change over time
