Explanation:
You are screening three new pesticides for potential mutagenicity using the Ames test. Two his- strains resulting from either a frameshift or a transition mutation were used and produced the following results (number of revertant colonies):
Strain 1
Transition Mutant Control (no chemical) Transition Mutant + Chemical Transition Mutant + Chemical + Rat Liver Enzymes
Pesticide#1 21 180 19
Pesticide#2 18 19 17
Pesticide#3 25 265 270
Strain 2 Framshift Mutant Control (no chemical) Framshift Mutant + Chemical Framshift Mutant + Chemical + Rat Liver Enzymes
Pesticide#1 5 4 5
Pesticide#2 7 5 93
Pesticide#3 6 9 7
Required:
What type of mutations, if any, do the three pesticides induce?
Answers
Answer:
- Pesticide 1: Induces transition mutations. Rat liver enzymes convert it into a nonmutagenic product. Does not induce frameshift mutations.
- Pesticide 2: Does not induce transition mutations. Rat liver enzymes convert it into frameshift mutagen.
- Pesticide 3: Induces transition mutations. Rat liver enzymes don't have ability to convert compounds into mutagens. Does not induce frameshift mutations.
Explanation:
The Ames test is a technique widely used to evaluate the mutagenic potential of a particular chemical compound. The Ames test uses Salmonella typhimurium strains with a defective mutation that makes them unable to synthesize histidine. When the mutation is reversed, then the revertant strains can grow on a medium lacking histidine. A positive test shows that the chemical is mutagenic because its activity is associated with the reversed mutation and thereby the mutant gene regains its function. In humans, as well as in other mammals, many chemicals don't have mutagenic effects themselves but they may become converted into mutagens when are metabolized by the body. For that reason, rat liver enzymes are added to replicate the metabolic effects of the chemical compound being tested. Nowadays, current tests can express recombinant human proteins instead of rat liver enzymes, thereby enabling a better correlation between mutagenic activity and human metabolic processes.

O C. Nothing
OD. A placebo
Answers
Answer: a medicine with known effect in the disease being studied
Explanation:
Answer each question, using it as an opportunity to illustrate the depth of your knowledge in this area.
1. One of the fundamental controls which ecosystems exert over individual species is limits on population size. This is done by a combination of predatory, competitive, parasitic and mutualistic relationships within the ecosystem. Never the less, the human population has increased well beyond what is healthy for those systems. How did we manage to grow beyond these limitations?
2. Natural variations in weather patterns have effects on certain populations. A warm damp spring for example, is ideal for small rodent species and certain insects, who benefit from the lush vegetation produced by this pattern. As a result, their populations swell to high levels. In the end however, this doesn't result in population growth at the higher tropic levels. You don't end up with more predators, just fatter predators. What limits the ability of the higher tropic levels to grow in response to the increased availability of food?
3. An unfortunate series of events finds you stranded on a remote uninhabited south Pacific island, with little chance of being rescued. It is a modest-sized island with adequate resources to support you, if you are careful to minimize your impact on it. You know that inserting yourself into this ecosystem will almost certainly mean the loss of members in some populations, so your goal is to minimize your impact on the overall biodiversity of the system. With this in mind, from which tropic level(s) should you obtain your food?
Answers
Answer:
1. Humans are an “invasive species” because human populations have eliminated many ecological relationships, dramatically changing the dynamic of their ecosystems
2. continued loss of energy due to metabolic activities
3. lower trophic levels
Explanation:
1. An invasive species is any organism that is not native to an ecosystem and may negatively alter its new environment. Invasive species don't interact with native species when they are introduced into an ecosystem (for example, invasive species usually don't have any natural predators). Humans are an 'invasive species' that occupy a wide range of habitats and whose presence has caused the extinction of many native plants and animals. Human populations have drastically reduced the biodiversity of different ecosystems by competing with native species for limited resources, and we also have altered their habitats (global human population growth is also due to medicine and farming techniques, reducing hunger and diseases). In this regard, it is important to highlight that the human population can also grow in an ecologically sustainable manner by taking care of the ecosystems we live in.
2. Animals (predators) are consumers, thereby they depend on lower trophic levels for their food supply. The Second Law of Thermodynamics indicates that the continual loss of energy due to metabolic activities at lower trophic levels leads to a decrease in the amount of available energy at higher trophic levels. In consequence, the population size decreases at higher levels due to the amount of energy available from one lower level to the next higher level has to decrease when it is used for metabolic activities (i.e., growth, development, etc).
3. In the food chain, the primary producers are found at the lower trophic level (e.g., plants). Primary producers are followed by consumers (e.g., herbivores), they are followed by secondary consumers (i.e., carnivores that eat herbivores), and so on. When an invasive species at higher trophic levels is introduced into a new ecosystem (in this case, human species), it is imperative to preserve the biodiversity (and consequently also the productivity) at lower trophic levels because they are fundamental for the survival of higher trophic levels (i.e., consumers).

Clean Combat Cross-Contamination Cook Chill

Answer:
1- Chill
2- Cook
3- Combat Cross-Contamination
4- Cook
5- Clean
6- Chill
7- Combat Cross-Contamination
8- Clean
Explanation:
A foodborne illness (also known as food poisoning) is an illness caused by eating contaminated foods by harmful microorganisms such as bacteria (e.g., Escherichia coli), viruses, parasites, and/or toxins (e.g., mycotoxins) contained in foods. Some of the most common symptoms of food poisoning include vomiting, nausea and diarrhea. Foodborne illnesses are generally caused by improper practices in the home kitchen, i.e., improper handling, preparation and food storage. Cross-contamination refers to the transfer of harmful microorganisms/toxins from one substance to another. The most common contributing factors to cross-contamination include equipment-to-food contamination, food-to-food contamination, and people-to-food contamination. The most important habit to prevent cross-contamination is washing hands and foods before eating and cooking. Moreover, cooking foods to proper temperatures can destroy microorganisms/toxins that cause foodborne illnesses. Finally, chilling (at 8˚C or below) and freezing (at -18° C) foods can also protect from food-borne illnesses as many harmful microorganisms cannot grow at these temperatures.
