Abortion is defined as the termination of a pregnancy. This can be a voluntary or involuntary process. An involuntary abortion is often referred to as a miscarriage‚ in which a fetus is prematurely expulsed from the womb. The term abortion is typically used in reference to a voluntary and deliberate termination. In either case of termination‚ the fetus is not carried to full term. There are a variety of reasons for which a female would undergo an abortion. Person conflicts are the leading reason

Pregnancy Discrimination Act of 1978 The Pregnancy Discrimination Act of 1978 is an amendment to the Title VII of the Civil Rights Act of 1964. It prohibits employers from discriminating against workers based on pregnancy‚ childbirth or related medical conditions. It affects only companies that employ 15 or more people. The Equal Employment Opportunity Commission (EEOC) enforces the Pregnancy Discrimination Act. Under the act‚ an employer cannot lawfully refuse to hire a woman if she is pregnant

There are four stages of sleep‚ stage 1 occurs when the person decides it’s time to fall asleep. Initially in stage 1 alpha waves start waxing and waning bursts of 8-12 Hz’s EEG. This is when we are alert at our wake fullness. Stage one sleep RRG is low voltage but high frequency signal. As the stages progress into stage 2 there’s a gradual increase in EEG voltage and decrease in EEG frequency. Stage 2 has a higher amplitude and lower frequency and also has two wave forms‚ k complexes and sleep spindles

RATE OF REACTIONS. The reaction rate (rate of reaction) or speed of reaction for a reactant or product in a particular reaction is intuitively defined as how fast or slow a reaction takes place. For example‚ the oxidative rusting of iron under the atmosphere is a slow reaction that can take many years‚ but the combustion of cellulose in a fire is a reaction that takes place in fractions of a second (right). Chemical kinetics is the part of physical chemistry that studies reaction rates. The concepts

Abstract This experiment is to study the effect of temperature on the rate of reaction between potassium permanganate with oxalic acid. We used 2cm3 of 0.02M potassium permanganate and 4cm3 of 1M sulphuric acid into a test tube. In another test tube‚ we placed 2cm3 of oxalic acid. We placed the test tubes in a water bath at 40‚ 45‚ 50‚ 55 and 60oC respectively. When the solutions have attained these temperatures pour the oxalic acid into the acidified permanganate solution and recorded the time

How to Prevent Teenage Pregnancy Each year the United States is acknowledged for having the highest number of pregnant teens in the industrialized world. We have clueless teenage females of every race having children while they are in high school. Sex is on the minds of so many teenagers that they forget that they are not yet at a stage of having children. Since it is difficult for adolescent girl to resist the temptation of having sex; a while abstinence is the best form of prevention‚ birth

Lab #4: Aqueous Reactions Introduction: In this experiment we studied the two different types of aqueous chemical reactions‚ double replacement and single replacement. In a double replacement reaction one or both of the products is an insoluble ionic compound or otherwise known as a precipitate; or a non-electrolyte; or a gas. In a single replacement reaction there is typically a metal and an ionic compound consisting of a metal cation and a non-meatl anion. Singel replacement ractions occur when

Abstract “Reaction Time” is the interval of time between the application of a stimulus and the detection of a response and has been thought to differ based upon the effects of modality and warning signals. In the “Reaction Time” experiment a total of 24 students from the University of Cincinnati participated in an experiment consisting of two sensory modalities‚ audition and vision‚ which were combined with two levels of warning signal status. The two levels of warning signal status were signal
