FRQ #3 a.) The first property of water is its polarity. A water molecule is formed by one oxygen atom covalently bonded to two hydrogen atoms. The electronegativity of the oxygen atom creates an unequal sharing of electrons between the O and H atoms of the molecule. This also gives water the ability to form hydrogen bonds between the slightly negative oxygen atom and the slightly positive hydrogen atom. Water has a high specific heat due to the hydrogen bonds. Because of this‚ water requires

Adriana Gutierrez AP Biology Lab 9 Analysis 1. For this experiment‚ what were the independent variable and the dependent variable? What were the constants? The independent variable of this experiment are the environmental factors that you are testing on the rate of transpiration‚ so our independent variables would be bright light‚ fan‚ dark‚ and misted. The dependent variable is the rate of transportation because this depends on whatever environmental factor the plant is placed. The constants

Question: In what ways were the late nineteenth-century Populists the heirs of the Jacksonian-Democrats with respect to overall objectives and specific proposals for reform? The Populists of the late nineteenth-century were in many aspects the heirs of the Jacksonian Democrats‚ carrying on the legacy and tradition left behind. The Populists were very similar to the Jacksonians in many of their overall objectives and specific reform proposals. During the Jacksonian Era from about 1828-1842‚ the

how not only heredity‚ but also environment‚ plays a role in the development of human beings. The field has evolved quite a bit in the last few years. Studying genetics helps us to be able to predict future behaviors and also potentially help us to use genetic engineering. Since the study of behavioral genetics can potentially lead us down the road of genetic engineering it attracts a lot of controversy. As will be examined here genetics shows some strong correlations between heredity and environment

Nisbett University of Michigan J. P. Rushton and A. R. Jensen (2005) ignore or misinterpret most of the evidence of greatest relevance to the question of heritability of the Black–White IQ gap.

used every tool available to free men to save Tom Robinson‚ but in the secret courts of men’s hearts Atticus had no case. Tom was a dead man the minute Mayella Ewell opened her mouth and screamed” (Lee 323). This clearly shows that despite Tom’s innocence and Atticus’ ability to defend him‚ Tom Robinson never would have had an opportunity of winning the court case because of his estrangement. The beliefs and opinions of this time period allowed a guilty man to be let free and an innocent man be convicted

When adopting parents and in the process of adopting a kid‚ they probably have a million questions on their mind stressing them out‚ but one thing that can’t escape their mind is whether the child came from a healthy family. Is it really necessary to worry about the child’s biological background? Some argue that the adopting parent should be worried because they think people behave as they do according to genetic predisposition”‚ but others argue that the adopting parents have no needs to worry over

The three structures that protect the Central Nervous System are Bone‚ Meninges and Cerebral Spinal Fluid. 3. Cerebrospinal fluid comes from the blood and circulates throughout the CNS before returning to the blood capillaries. CFS is a clear‚ watery fluid containing a few cells and some glucose‚ protein‚ urea and salts. Occupies the space between the middle and inner layer of the meninges. It
