Autosomal Inheritance of Wrinkled and black Mutations in Drosophila melanogaster Abstract Homozygous Wrinkled virgin females and homozygous black male Drosophila melanogaster‚ were crossed. Mutations were located on chromosome two and three respectively. The F1 generation‚ all Wrinkled and black‚ was inbred yielding and F2 generation. A phenotypic ratio of 9:3:3:1 was hypothesized with wrinkled wings and wild type body: wrinkled wings and black body: wild type wings and body wing: wild type wings

The Histamine Theory The immune system uses different types of white blood cells to defend the human body against foreign invaders. Of these white blood cell types‚ basophils are designed to release histamine. Histamine is most commonly associated with allergic reactions‚ but its true purpose is to increase blood flow to an area of the body the immune system deems under attack from foreign substances. These white blood cells also serve as an attractor for other cells needed to fight off invading

Biochemistry‚ GRT1 Task 2 Essential Amino Acid Valine A1: 2 Characteristics of Valine • Valine is a nonpolar amino acid‚ with many carbons surrounded by hydrogen. Valine is unable to interact with water molecules‚ making it HYDROPHOBIC (MSDS‚ 2005). • Flammability- Valine is combustible at high temperatures. These products are carbon oxides and nitrogen oxides. In case of a small fire‚ dry chemical powder should be utilized. In case of a large fire‚ utilize water spray‚ fog or foam. No water

have neurotransmitter-like properties‚ and many additional true neurotransmitters may await discovery. The first of these families‚ and the group about which most is known‚ is the amine neurotransmitters‚ a group of compounds containing a nitrogen molecule which is not part of a ring structure. Among the amine neurotransmitters are acetylcholine‚ norepinephrine‚ dopamine‚ and serotonin. Acetylcholine is possibly the most widely used neurotransmitter in the body‚ and all axons that leave the

tests previously learned are not enough to identify organic compounds. Functional groups present in organic compounds must be identified. Acetyl chloride test can be used for alcohols‚ amines and phenols. A positive result for alcohol is the formation of a separate layer‚ and is usually accompanied by heat. For amines‚ solid amides were formed. Alkaline

function groups. The amine and amide functional groups are the most polar. In this experiment‚ we found that both these functional groups are found in Caffeine. As a result‚ Caffeine was the most polar out of Acetylsalicylic Acid‚ Ibuprofen‚ Acetaminophen‚ and Caffeine. Aside from Caffeine‚ Acetaminophen has one amide functional group. This makes it the second most polar analgesic. In addition‚ Acetylsalicylic Acid has an ester group. Since ester group is not as polar as either amine or amide groups‚
