THE ABORTION BATTLE Title: Abortion: Killing a Human Being Topic: The ethics behind the practice of abortion and validating it as a murder Specific Purpose: To inform students of the scientific procedure of abortion and paralleling it to the killing of a human being‚ just in vivo (during conception). INTRODUCTION *ask class question‚ give disclaimer* Attention Materials: Mention the story of a Philadelphian doctor who committed wrongful abortions. Segue into the the fetus from conception to its

the embryo inside of a woman is a living thing. The embryo has genetic make up from the time of creation‚ therefore it is a living thing. Brian Fisher states that‚”A zygote is a unique being that is distinct from the mother. He or she has 46 unique chromosomes and is internally driven to grow into more mature stages. Therefore‚ a zygote is fully human — as is an embryo‚ a fetus‚ and a born baby.” A embryo will

Mitosis vs. Meiosis Cell Division is the process of dividing a parent cell into multiple daughter cells by using the Cell Cycle. The Cell Cycle itself is composed of the Interphase‚ usually Mitosis‚ and Cytokinesis. The Interphase‚ which takes up 90% of the Cell Cycle‚ is composed of three phases: Growth 1 (G1)‚ Synthesis (S)‚ and Growth 2 (G2). In the G1 phase‚ the cell grows its size‚ replicates any organelles‚ and functions normally. In the S phase‚ it would prepare to divide its nucleus. Lastly

Green algae have many similarities to land plants. It has many variety body types and the multicellular forms do not have cells separated into tissues‚ which is what divides green algae from land plants. Green algae are a very diverse group of freshwater algae. Many green algae form long filaments. The cells stay attached after they divide. Spirogyra can become so numerous they form dense mats of growth in surfaces of ponds‚ which is called pond scum. This pond scum is interesting to see through

Mitosis took place between the first and second week as well as the second and third week observations. The spores underwent mitosis to form gametophytes. The gametophytes then underwent mitotic division to form two distinct types of gametophytes. The zygote also went through mitosis to develop the sporophyte. Mitosis is the process that creates haploid gametes‚ because it ensures the haploid gametes do not loose half of its chromosomes and cell data‚ which would be the result if it underwent meiosis

cell unite in one of the two fallopian tubes. The fertilized egg‚ known as zygote then moves toward the uterus‚ a journey that can take up to a week to complete. Cell division begins approximately 24 to 36 hours after conception. Within just a few hours after conception‚ the singe-celled zygote begins making a journey down the fallopian tube to the uterus where it will begin the process of cell division and growth. The zygote first divides into two cells‚ then into four‚ eight‚ sixteen‚ and so on

Meiosis How does sexual reproduction lead to genetic variation? Why? Cells reproduce through mitosis to make exact copies of the original cell. This is done for growth and repair. Sexually-reproducing organisms have a second form of cell division that produces reproductive cells with half the number of chromosomes. This process is called meiosis‚ and without it‚ humans‚ oak trees‚ beetles‚ and all other sexually-reproducing organisms would be vastly different than they are today. Model

11 Genetic and Environmental Influences on Human Development 11.1 Introduction We may often wonder about the reasons and forces which shape our personality and character. Each one of us has a specific kind of nature which takes that particuler form because of the effect of two major factors. The first is the genetic make-up which we inherit from our parents‚ and the second influence comes from the various experiences we have in our interaction with our surrounding environment. This includes

to a sibling that is affected with a fatal or debilitating disease. The savior sibling is conceived through in vitro fertilization. Fertilized zygotes are tested for genetic compatibility (human leucocyte antigen (HLA) typing)‚ using preimplantation genetic diagnosis (PGD)‚ and only zygotes that are compatible with the existing child are implanted. Zygotes are also tested to make sure they are free of the original genetic disease. A revolutionary technique called ’pre-implantation process’ is used
