The sexually transmissible disease gonorrhea has become increasingly resistant to treatment with antibiotics. What is the most likely scientific explanation? a) The gonorrhea bacteria learned to avoid antibiotics b) The gonorrhea bacteria changed their genes when they sensed antibiotics c) Antibiotic-sensitive gonorrhea bacteria died out, but antibiotic-resistant gonorrhea bacteria have flourished and persisted d) The antibiotic increased the mutation rate in the gonorrhea bacteria e) Both b and d 26. Which statement best describes the relationship between plants and animals on earth? a) Plants produce O2 and sugars from CO2 b) Animals produce CO2 and H2O from sugars and O2 c) Plants produce O2 and sugars and animals produce CO2 and H2O d) Animals produce O2 and sugars and plants produce CO2 and H2 27.
For example, tomatoes are injected with fish gene to make a new product with better quality because the components in fish can protect fruit from freezing. Nevertheless, this matter can cause a serious consequence for people who get allergic with fish. Hence, labeling will allow consumers to identify and steer clear of food products that could cause them problems. Last but not least, labeling GM foods
Given that mycotoxins may have carcinogenic properties, you should immediately remove yourself from any black mold environment and have the spores professionally removed. Black Mold vs. Other Molds • All molds can potentially cause respiratory symptoms as the spores enter your lungs, but not all molds contain pathogens or mycotoxins. Some of the more common household molds, like Penicillium and and Cladosporium, are far less harmful and only pose a threat to asthma sufferers and people with respiratory conditions. The toxigenic molds, like Aspergillus and of course black mold, can pose a threat to
The rings of growth in the lawn are caused by the release of nutrients, specifically nitrogen because of the activity of the fungus living on organic matter in the soil. These organisms are mushroom or “puffball” forming fungi. Some mushrooms or puffballs are very poisonous when eaten and it is important that they are routinely destroyed if small children are likely to be attracted to them. There are three kinds of fairy rings. The first type has no mushrooms just stimulated grass growth revealing the activity of these fungi in soil.
Food Coloring Ever wonder why our food products come in crazy colors when they have a successful normal colored product. The reason is because the brighter color attracts your attention and most importantly, children’s attention. Ever wonder if Food coloring is bad or not healthy? In this speech I’ll explain the history, hazards, value, regulations and if it is unhealthy. The history of food coloring goes as far back as ancient Rome where they used saffron and other spices to put a rich yellow color into their food.
The black seeds inside the pawpaw can be ground and used as a substitute for black peppers and they have deworming effects. However, they shouldn't be consumed in large quantities because they contain a toxic substance called Carpaine which can lower the pulse
They have their own way of moving called locomotion and different types of structures. They could be both bad and good to the environment. Helpful microorganisms help us make cheese and yogurt. They help us make bread and ferment beer and wine and alcohol for fuels. Harmful microorganisms are those that cause disease in humans or animals and cause your pool to turn green.
Food Irradiation and Its Effects on Consumer Health Food irradiation is a process that the food industry uses to reduce harmful, disease causing bacteria and increase the shelf life of foods by destroying decay causing microbes. While this process has been proven to be safe by the Center for Disease Control and the Food and Drug Administration, public misconception of the process has created doubts as to its safety and effectiveness. Through public awareness and education of this process, many concerns and misbeliefs can be dispelled. Food irradiation is performed using three different technologies, using three different kind of rays: gamma rays, x-rays, and electron beams. The different uses will depend on the food being irradiated as each technology has strengths and weaknesses.
This way of improving foods has been taking place traditionally by just crossing two plants together and hoping that the new traits are taken without any negative ones (543). Since this is time consuming and not as accurate, scientists now just introduce the new genes, or traits, through the plants’ DNA. Genetically Engineered foods, although meant to be helpful, pose many problems by causing environmental hazards, human health risks, and economic concerns. To begin with, one of the problems with engineered foods is that they can become hazardous to the surrounding environment. This unintended harm to other organisms is caused by many factors.
The echinocandins inhibit the synthesis of fungal beta-1,3-glucan and so prevent cell wall synthesis. Voriconazole is a newer triazole and as such has a broad spectrum of activity. It can be taken both orally and intravenously. It is useful in treating invasive aspergillosis, as well as resistant candidial infections. It may be even better than Amphotericin B with respect to treatment efficacy and patient survival.
