AP Biology Outline for Behavior Territoriality - behavior of animals that enables individuals to occupy and dominate an area. Territory is an area where one or more individuals defend the area. Thus the two are interpedently interacting with each other to defend the area.

One day when I was in the fourth grade‚ we had just finished a free response test on a story we were supposed to read last night. The next day‚ my teacher had completed grading all the test and he had noticed that two of the papers had were the exact same‚ their names were Danny and Ishmael. But Danny was absent today so the teacher called Ishmael to the front of the classroom and asked him if he and Danny cheated off of each other’s test. Ishmael first lied and said‚ “I don’t know how we have the

1. (a) I‚ III‚ and IV are correct. II is not correct. To explain III‚ de Broglie’s equation states l = h/(mv)‚ so nl = nh/(mv) = 2pi(r). Where: l = wavelength‚ v = velocity of electron‚ n = some positive integer‚ r = distance of electron from center‚ m = mass of electron. Solve‚ get mvr = L = nh/2pi. (b) The current wave mechanical model for the atom states that there are an integer number of wavelengths in every standing integer number (n). 2. (a) The first shell electrons in Lithium are

Throughout the period 1801-1817‚ the government was ruled by the Jeffersonian Republican party‚ whereas the Federalist Party began to slowly fade away from public view. The Jeffersonian Republican party‚ led by Thomas Jefferson‚ professed to favor a weak central government through the support of more states’ rights‚ "...that the states are independent... to...themselves...and united as to everything respecting foreign nations." (Document A). On the other hand‚ the Federalist Party‚ previously led

Abuse and Heredity Research question: Is child abuse hereditary? There are many types of abuse such as alcohol abuse‚ drug abuse‚ domestic abuse just to name a few but of all the types of abuse there is one type of abuse that is probably one of the easiest to pass down and that is child abuse. Child abuse is easy to pass down because we look to what we know when were not certain what to do. The term for passing down child abuse is known as intergenerational abuse. There are four methods of child

Biology Key Questions – Lesson #1 1. How many electrons does Mg2+ have? Answer: Mg2+ has 10 electrons. A Magnesium atom has 12 electrons‚ 2 of which are valence electrons. The atom will lose the 2 outermost electrons in order to stabilize its electron shell. The nucleus maintains its 12 protons and becomes a Mg2+ ion. 2. Given that the half-life of the radioisotope carbon-14 is 5730 years‚ how useful do you think this isotope would be for dating bones that are over a million years
