Alfredo Salazar 1/28/2013 What have you learned? Chapter 1 1. What makes the study of human development a science? It seeks to understand how and why people‚ all kinds of people‚ everywhere‚ of every age‚ change overtime. 3. Why have recommendations regarding the sleeping circumstances of infants changed? Every year until the mid-1990‚ thousands of 2 to 4 month olds died of SIDS. Susan Beal hypothesized that sleeping position might matter‚ as a result‚ SIDS rate dramatically decreased.

family history and traditions. Identity defined in class notes- The development of identity involves finding out who we are‚ what we value‚ and where are we headed in life. Identity Formation is made up of many components: Physical (your race‚ phenotype dress etc) Social (including cultural‚ vocational‚ ideological‚ generational etc) Sexual (your orientation) Gender (which is sometimes physical and other times a mental construction) All of these contribute to something known as: Self Concept

DISCOVERIES Gregor Mendel‚ also known as "The Father of Genetics" was an Austrian monk that made a huge discovery about genetics because of his mini garden full of pea plants. What made Mendel come to this experiment was because of the different phenotype or traits of the pea plants. Some were tall and some were short. Some plants either had purple or white flowers. Gregor observed each trait and saw how they were passed down to the offspring plants. After breeding plants‚ Gregor Mendel learned

According to Google‚ the definition of racism is the belief of all members possesses characteristics or abilities specific to that race. This definition gives a negative view to racism and slavery‚ and it should. The lingering effects of slavery and racism still haunt people today and will continue to do so for years to come. It all started when the first white people settled on America and they needed extra work for their farms. Now slavery and racism happens in school‚ jobs‚ homes etc. There are

Definition: Epigenetics are the changes in the gene expression which are not caused by changes in the DNA sequences‚ meaning it a change in the phenotype but not the genotype. It is the study of the genes that are possibly inheritable. The environment you live in plays a key role in epigenetics and how your genes are expressed. How does epigenetics have anything to do with digestion? A chemical tag is something that can alter a gene expression. It attaches onto the DNA and blocks transcription.

The Frequency of Mutations among Second Generation Drosophila melanogaster INTRODUCTION This experiment involved observing and comparing the relative frequencies of inherited dominant and recessive genes in a population using the common fruit fly Drosophila melanogaster. In this experiment‚ we demonstrate how dominant genes are selected over recessive genes (Mendel’s Law of Independent Assortment). Hypothesis: If we cross two heterozygous individuals‚ our observed offspring in the second

Evolution Unit: Objectives AP Biology Upon the completion of the textbook readings in Chapters 22-26 you should be able to: Chapter 22 1. Explain how the principle of gradualism and Charles Lyell’s theory of uniformitarianism influenced Darwin’s ideas about evolution. The basic idea of natural selection is that a population of organisms can change over the generations if individuals having certain heritable traits leave more offspring than other individuals. The result of natural selection

One method used to obtain the “pure aryan race” was the lebensborn program‚ the word Lebensborn means “Fount of Life” (SS). The Nazis invented this program in order to create more supervised mating between pure aryan women and loyal SS men‚ so that their offspring would be more “Biologically valuable” (Reich 771). The lebensborn program used private funding‚ and was seen by the Nazis as a place for pregnant aryan women to go and receive protection while they were carrying a child. Mothers were allowed

Plants vs. Zombies: A Lesson on Artificial Selection and Classification Team Name: Team Members: Performance Task: There is a Zombie Apocalypse caused by a comet that traveled too close to the earth. People who were not sheltered during the comet’s passing were turned into zombies. It is believed that the comet was created by aliens to prepare our planet for invasion. Plants and Fungi were also affected by the comet and mutated and now carry many unusual traits. For some unknown reason these plants
