The major storage polysaccharide in plants is starch. These molecules would be found in abundance in the stroma in the plant tubers where it is found as granules. Glucose is stored mainly in the form of starch granules, in plastids like chloroplasts and amyloplasts. Plant starch starts out as glucose, but glucose is very hard for plants to store, so it is converted to starch through polymerization. Amyoplasts turn the glucose into starch and move it to the stroma, and in tubers the stroma is a place to store the food (starch), and when plants need the energy in the starch, it converts the starch back into glucose.

In this project, C. Elegans are hermaphrodite worms that will be used since they are easy to maintain in lab, as well as have short life cycles. The gene that the project attempted to knockdown in C. Elegans with RNAi treatment is the unc-22 gene. RNAi disrupts gene expression in the presence of double stranded RNA (dsRNA) that is complementary to target gene sequence. The unc-22 gene codes for a muscle protein called twitchin in wild-type worms. The Unc-22 is required for muscle regulation and maintenance in C.Elegans. To verify that the RNAi treatment worked, would check the unc-22 mRNA levels in the worms, in addition to phenotype observation.

Predominant life fuel resource changed during the body development. ATP is mainly sourced from glucose at fetal phase, then gradually shift to fatty acid metabolism after birth. Studies proved that individuals born with a low birth weight (LBW) have an increased risk of cardiovascular disease in adult life, which glucose transport and related metabolism involved. In this paper, author use the lamb as the IUGR model, tried to find out the effect of changes in the intrauterine environment that result in LBW on key regulatory proteins involved in cardiac glucose metabolism, glucose transport and fatty acid metabolism.

The mole is a convenient unit for analyzing chemical reactions. Avogadro’s number is equal to the mole. The mass of a mole of any compound or element is the mass in grams that corresponds to the molecular formula, also known as the atomic mass. In this experiment, you will observe the reaction of iron nails with a solution of copper (II) chloride and determine the number of moles involved in the reaction. You will determine the number of moles of copper produced in the reaction of iron and copper (II) chloride, determine the number of moles of iron used up in the reaction of iron and copper (II) chloride, determine the ratio of moles of iron to moles of copper, and determine the number of atoms and formula units involved in

1.) My hypothesis that the insects would be most repelled by the lemon plant extract was not supported. Our key findings in the experiment do not support my hypothesis because the lemon had a 60% repulsion response and was the second most repulsive behind orange with a 70% repulsion response. Although the Earthworms were repelled by the lemon plant extract, they were more so repelled by the orange plant extract. 2.)

Introduction We conducted an experiment to see if certain areas in the Daniel Stowe Botanical Gardens, attract certain species of insects. Our group came up with a hypothesis that different type of trees in different locations attracts certain types or certain amounts of insects. Daniel Stowe Botanical is a botanical garden located in Belmont, North Carolina. We chose Danial Stowe, because of its very diverse ecosystem. We thought that since the ecosystems are so diverse that the species of insects should be as well.

Bacteria is a single celled organism, bacteria have evolved to thrive in almost any environment and can be found in almost any substance/surface and also in the human body, only 1% of bacteria is actually harmful.

An association between enzyme production, gene copy number, and gene evolution was explored by conducting analysis of the salivary amylase enzyme, AMY1A gene copy number, and the ancestral starch consumption in Homo Sapiens (Tracey 2017, p.22). It was hypothesized that the relative amount of starch consumption was very high for my personal ancestral diet, thus my AMY1 diploid gene copy number in my genome and salivary amylase concentration would be significantly higher than the population mean. With a population of 28 subjects (n=28), individual saliva samples were collected and compared to a calibration curve to determine the approximate amylase concentration by analyzing absorbance values. Individual samples of buccal cheek cells were

Microorganisms are both beneficial and harmful. These microorganisms are important to humans because they play a role in the ecology of life, by decomposing wastes, both natural and man-made, such as creating nitrogen fertilizer at the root zones of certain crops. Other several pathogens that can cause serious harm, even immediate death due to the diseases or disease causing products they produce. Overall, microorganisms play an important role in life.

Bacteria will always want to thrive and do what is best for itself and find the most suitable host. The ideal situation between a host and bacteria would be mutualism which is a form of coevolution in which two species benefit from the same act. Michal Pollen briefly discusses this in Botany of Desires by comparing both bees and flowers. When he puts himself in the mind of the bee he can understand that the plants were luring the bees for there own desires. In other words, the plants get the bee to perform activities that they cannot themselves.

The Kingdom Eubacteria (true bacteria) was once placed as a phylum under the Kingdom Monera. Today, due to the acknowledged differences, the Kingdom Monera was split into two different Domains: Bacteria and Archaea. The Domain Bacteria (Kingdom Eubacteria) consists of prokaryotic organisms that can survive in a wide range of moderate environments. Bacteria are often portrayed as the villains in society - our main focus being the pathogenic bacteria (disease-causing). However many bacteria are not only beneficial for humans, but are necessary for life. For example, bacteria in our digestive system help us to break down food, like plant fibers, that we’re unable to properly do ourselves. Escherichia coli (E.coli), found in the human intestines,

HIV is global pandemic stands for Human Immunodeficiency Virus, weakens the immune system by destroying the important cells in our body that fights against disease and infection. Our immune system is able to clear out most of the viruses from our body, but once you have HIV , you have it for lifelong. HIV can hide in our body cells for long time and it can attack the T cells and CD4 cells, a key part of our immune system to fight infections and diseases. Overtime, the HIV may attack so many of CD4 cells and our body is no more able to fight against infections. When this happens, HIV can lead to AIDS, the final stage of HIV infection. HIV can be transmitted through sexual contact, injection or drug use, pregnancy, breast feeding, occupational exposure, and rarely through blood transfusion and organ

Currently, there are no vaccines and no cures for HIV or AIDS, although scientists are researching and finding new drugs and treatments. So far, scientists have discovered a variety of drugs and medication that can be used to control and slow the virus and the progression of the disease. There are some drugs which interfere with the virus ability to make copies of itself by disabling a protein it needs, like Non-nucleoside reverse transcriptase inhibitors. If someone is diagnosed with HIV, it is important to start with treatments as soon as possible.

Human immunodeficieny virus (HIV) is a virus that produces AIDS (HIV/AIDS: MedlinePlus Medical Encyclopedia). The HIV virus attacks and weakens a person immune system. People with weaker immune systems are at higher risk of contracting infections or cancers. The HIV virus is spread from person to person through sexual contact, blood, and from mother to child. The people that are at higher risk of contracting HIV are drug users who share needles, and people who have unprotected sex. When someone is diagnosed with HIV they often have to get blood test to check their CD4 cell count. A person that is healthy has a CD4 count that is from 500-1500 cells per cubic milliliter of blood. A person that becomes infected with HIV may start to feel symptoms when their CD4 count drops below 350. If the count drops under 200 then the person is diagnosed with AIDS. The name of the treatment that people with HIV/AIDS receive is called antiretroviral therapy (ART).Overall, people that undergo treatment and take care of themselves can live a normal life (HIV/AIDS: MedlinePlus Medical Encyclopedia).

Human Immunodeficiency Virus (HIV) is a dangerous virus that attacks the human immune system. Someone infected with the virus can live with HIV, or be HIV positive, for many years without any illness or showing symptoms. During this time, HIV remains in the body damaging the immune system and the person remains infectious. HIV causes Acquired Immune Deficiency Syndrome (AIDS) if it remains untreated. AIDS is a stage of HIV where one can have life threatening illnesses. However, infection with HIV does not mean that one has AIDS. AIDS is the last stage of HIV and people can lose their lives at this stage. HIV is a virus that can be transmitted but AIDS cannot be transmitted. (Can.org.au, 2008)
