INTRODUCTION TO INFERTILITY Not everyone has the goal of becoming a parent, but for those who do, being unable to conceive a child is an exquisitely painful reality. Many of us spend a portion of our lives attempting to avoid unplanned pregnancies, and assume that once we are ready to conceive, it will happen with little difficulty. We tend to think that shifting gears from preventing pregnancy to planning conception and childbirth will proceed in a relatively smooth and orderly fashion. A failure

Study Guide for 301 Chapter 1 Development - the pattern of movement or change that begins at conception and continues through the human life span. Life Span perspective = views development as lifelong, multidimensional, multidirectional, plastic, multidisciplinary, and contextual and as a process that involves growth, maintenance, and regulation of loss. Life expectancy – the average # of years that a person born in a particular year can expect to live Multidimensional – for example can include

Skinner v. Oklahoma 1. Skinner v. Oklahoma, 316 U.S. 535 (1942) This case touches a sensitive and important area of human rights. Oklahoma deprives certain individuals of a right that is basic to the perpetuation of a race-the right to have offspring. Oklahoma has decreed the enforcement of its law against petitioner, overruling his claim that it violated the Fourteenth Amendment. Because that decision raised grave and substantial constitutional questions, we granted the petition for certiorari

entire period is about a quarter of a cup. Ovulation is one part of the female menstrual cycle whereby a mature ovarian follicle (part of the ovary) discharges an egg (also known as an ovum, oocyte, or female gamete). It is during this process that the egg travels down the fallopian tube where it may be met by a sperm and become fertilized. The menstrual cycle can be divided up into 4 stages; Luteal (often know as the Secretory stage) The

reassortment. Marks the location of crossover between two nonsister chromatids. Diploid number - The total number of chromosomes present in a cell. Gametes - Cells with the haploid number of chromosomes. Gametes are created out of germ cells. The sperm and eggs involved in sexual reproduction are gametes. Genetic Reassortment - A process in which DNA packaged as a chromosome is broken and fragments are exchanged with another independent chromosome. Occurs during prophase 1 of meiosis. Germ cell -

The termites are an interesting group of insects. They are some of the only hemimetabolous insects that can undergo true eusocial behaviors. This ability to form a close-knit community allows them to form a super-organism. This super-organism is built upon actual individual organisms, which are the different castes in a termite mound. Termite social behavior can be a lot like human behavior in many ways, depending on the human culture you're looking at. In most western human cultures, we lack the

Against Embryonic Stem Cell Research When does the beginning of life start? Does it start at conception? Or does it start at birth? I believe life starts at conception. Conception, or fertilization, is when the sperm and the egg unite to produce a genetically unique individual (Ertelt). Some people believe it starts as soon as the heart starts beating. Some believe life starts with the first breath. And, others believe life starts when the fetus can live without the mother. Obviously there are plenty

they need and will have to undergo. In addition, there are 3 different types of down syndrome. Trisomy 21, Translocation and Mosaicism. Standard Trisomy 21 is when an extra 21st chromosome is duplicated. The extra copy could come from the egg or sperm cell. Translocation is caused when pieces of the 21st chromosome is located on another chromosome such as 14 or 17. And finally Mosaicism, Mosaicism is the presence of multiple types of cells with different genotypes in one individual cell. An
