both organic esters. An ester is a compound that is formed when an acid (containing the COOH group) reacts with an alcohol (a compound containing an -OH group). O C R1 O H O + H O C R2 R1 O R2 + H O H acid alcohol ester water Here R1 and R 2 represent groups such as CH3 - or CH3 CH2 -. The reaction type shown above may be called a condensation reaction because the small molecule H 2 O is eliminated from the reactants while the remaining bits of the reactant condense

Water is a chemical compound with the chemical formula H2O. A water molecule contains one oxygen and two hydrogen atoms connected by covalent bonds. Water is a liquid at standard ambient temperature and pressure‚ but it often co-exists on Earth with its solid state‚ ice‚ and gaseous state (water vapor or steam). Water also exists in a liquid crystal state near hydrophilic surfaces. Water is considered a purifier in most religions. Major faiths that incorporate ritual washing (ablution) include Christianity

counterparts. Often denied access to proper education‚ goods‚ property and freedom‚ colored people were continuously exploited as property themselves and unwillingly later became slaves to the elite classes. As a result‚ the notion of a slave owning property‚ of property owning property‚ quickly became rejected as plausible. Afterall‚ slaves were constantly “working from sunup to sundown” (234) and lacked the funds and skills necessary to acquire property. However‚ author Philip D. Morgan dismisses this stereotypical

sucrose and caffeine receiving plants‚ and inaccurate in the case of the plant receiving carbonated water. To begin with‚ it is important to note the control plant experienced unusual results‚ as the plant had a sharp decrease in the quantity of blooms. However‚ the height and width experienced little deviation and the coloration and structure of the plant experienced no significant change during the experiment. Therefore‚ the hypothesis remains true for the control‚ even with the obvious

of the consequences of excessive drinking. After connecting with her‚ I wanted to know if alcohol concentration in spirits would affect the cells in the body. Thus‚ I decided to test my theory by adapting a class beetroot experiment to my investigation. The aim of this experiment is to investigate the effect of alcohol concentration on a biotic cell membrane. The human body cannot live long with damaged cells because they are the building blocks of life. Cell membranes are phospholipid bilayers meaning

Marine biologists work hard day in and out to put an end to these terrible things that occur more often that one thinks. Did u know Water covers the 71 percent of the earth.

Su material nuclear se encuentra flotando en el citoplasma. Las bacterias se clasifican como procariontas. Las celulas eucariontas son las mas avanzadas y contienen organelos rodeados por membranas. Su material nuclear esta rodeado por una membrane nuclear. Las celulas de las plantas‚ los hongos y los animals son eucarionticas. Las celulas de las plantas

Our assignment is about how chromosomes separate and how cell division works through microtubules and histones. DNA in the nucleus is loose and not well defined into chromosomes because it is usually tightly coiled‚ but in the interphase nucleus the chromatin exists in two forms: loosely coiled form called euchromatin and tightly coiled formed called heterochromatin. These two types become more coiled to form the chromosome at the time of cell division. DNA is a bit loosely coiled in the euchromatin
