Coliform bacteria

Scientists have not found antibiotics that are effective since the pathogens are multi-drug resistance. Multi-drug resistance is top three on global public health that are mostly caused by nosocomial infections (hospital-acquired infection caused by bacteria, fungal and viral, parasites and other pathogens). The six pathogens are Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumonia, Acinetobacter baumannii, Pseudomonas aeruginosa, and several species of Enterobacter. Instead of…

Katherine Sanders BIOL-1406 Dec. 4, 2017 Formal Lab Report I. Purpose / Objectives The purpose of this lab was to imitate natural selection in a controlled environment. II. Hypotheses Hypothesis 1 – Size Null: There will be no difference in which of the beans will be picked first, based on size. Alternative: The smaller beans will be more likely to be picked last, therefore, they will survive and reproduce. Hypothesis 2 – Color Null: There will be no difference in which of the…

Introduction to Cell Biology – Unit 10193 – Chloe Barrett This essay discusses the difference in prokaryotic and eukaryotic cells, two types of specialised eukaryotic cell, and the relation of the structure of cell membranes to their function of moving substances in and out of cells. Prokaryotic and Eukaryotic cells are two very different, but also very similar cells. There are many differences between them that can help to associate between each one. Eukaryotes are any organism that…

Hookworms are small and short worms. They live in the small intestines of man. They are called hookworms because each of them has hooks on its head around the mouth. The worm attaches itself to the inside wall of the intestine by these hooks. Hookworms feed on blood. They suck this from the wall of the intestine to which they are attached. There are often several hookworms at the same time in the child's tummy. All of them feed on the blood of the child. Therefore, one of the major effects of…

Costus speciosus (J.König)sm is a widely used medicinal plant in Ayurvedic medicine. Scientific literature prove about various therapeutic properties of its rhizome and leaves. The effectiveness of Costus speciosus (J.König)sm leaf aqueous extract on reversing insulin resistance was studied and data were published previously. This study was designed to evaluate the dose-response relationship of Costus speciosus (J.König)sm leaf aqueous extract. Insulin resistance induced rats were treated with…

ANALYSIS OF RESULTS: The limiting factor of area is the size of the polystyrene cup used in the experiment. Each of the polystyrene cups was the exact size in order to be able to determine how different amounts of fertilizer affected the duckweed growth. Hence, the factor of size could not be investigated as each different amount of fertilizer was exposed to the exact same area. This can be linked to the literature review that discusses how the area where it is growing affects duckweed growth.…

Plant proteases with excellent catalytical properties perform many functions in biological systems. Vallaris solanacea, a new plant protease has been identified and screened effectively for its caseinolytic activity. This protein activity was specifically inhibited by p-chloromercuribenzoate, which showed that it is a cysteine protease. Preliminary investigations such as effect of pH and temperature on the caseinolytic activity of crude protease were done. Stability towards temperature and pH…

body, part of the body or biological system after a wound or as a normal process. It is the process that makes the genomes, cells and organisms flexible to natural changes that cause disturbances or damage. All species are able to regenerate from bacteria to humans. Regeneration can be of two types: it can be complete when the new tissue is equal to the lost or incomplete tissue when the necrotic tissue presents fibrosis. Different organs have the intrinsic ability to regenerate, a distinctive…

FTIR Spectroscopic Study on Inner Membrane of Egg Shell of Chicken Gallus gallus domesticus Abstract: The paper presents FTIR analysis of inner membrane of eggshell of chicken Gallus gallus domesticus. Fresh samples of egg shells are cleaned; dried and inner membrane of the shell is separated carefully for FTIR analysis. FTIR spectrum reveals a series of bands related to fats and proteins. Calcium carbonate is the major constituent (about 90%) of the shell, but it is absent in the inner shell…

1.2 Cellular DNA Damage responses, genomic instability. DNA is the blue print of life and all the information of life processes such as growth, metabolism, reproduction etc are encoded in the sequence of it. Therefore its very important to maintain the genomic integrity of this genetic material, not only to keep away defects in life processes but to pass a faithful information to the next progeny. Integrity of the DNA is usually challenged by both endogenous and exogenous agents who are capable…
