How does E. coli become resistant to antibiotics? How do helminths evade the immune system? What is a propagated epidemic? How does Yersinia pestis attack and spread? How does HIV mutate? How can bacteria acquire drug resistance besides through mutation?
Organisms other than humans can be infected by influenza -- what are they? How does it spread within and between species, and what determines whether productive replication of the virus occurs? Explain airborne droplet transmission and give two examples of diseases they cause. ...
Neuroimmunology is one of the fastest-growing fields in the life sciences, and for good reason; it fills the gap between two principal systems of the organism, the nervous system and the immune system. Although both systems affect each other through bidi
different genes engaged in several cellular operation, like cell period adjustment, DNA mending (hMLH1) and methyl guanine DNA methyltransferase (MGMT), E-cadherin, H-cadherin and ganglionic polyposis coli, apoptosis(DAPK), TMSI and caspase-8 and angiogenesis [thrombospondin-1(THBS-1) and p73] ...
While the bacteria-killing properties of chlorine are very useful, chlorine also has some side effects that can be annoying to humans, and possibly even hazardous. Chlorine has a very distinctive smell that most find unpleasant, and some find overwhelming. There is also the "itch factor" -- ...
near-zero power levels. Effects that have been found at 0.02 picowatts (trillionths of a watt) per square centimetre or less include altered genetic structure in E. coli and in rats,[96] altered EEG in humans, growth stimulation in bean plants,[98] and stimulation of ovulation in ...
Instead of a long loop of DNA like our trusty E. coli bacterium, cells of plants and animals have chromosomes that hold the DNA strands. Humans have 23 pairs of chromosomes, for a total of 46 chromosomes. Fruit flies have five pairs. Dogs have 39 pairs, and some plants have as many ...
Another hidden pollutant is animal feces. Whether in the backyard, along a path or at the beach, feces washed into the storm drains eventually reaches streams and waterways, spreading potentially hazardous bacteria including E. coli. So, pick up your pet's droppings. ...

E. coli What Are the Benefits of Cockroaches? While most people consider these bugs a pest, they are important in the environment. For example, they play a role in: Food webs.American cockroaches are an important source of food for lizards, birds, mice, and other insects. They are also ...
