Answer:
Pasteurization is the process by which food products (such as juice and dairy products) are mildly heated to kill off harmful bacteria, salmonella, and other disease-causing pathogens. These products are thus made safe for consumption. ... Pasteurization has revolutionized food safety within the dairy industry.
Risk assessment is often used to set “acceptable” levels of toxins for the environment. Propose a concern people may have about using risk assessment in this way.
The concern about risk assessment of acceptable levels of toxins can be a failure to use appropriate risk metrics, incorrect measuring of known risk, failure to take known risks into concern, or failure in risk communication or risk monitoring.
What is meant by risk assessment?A risk assessment is a step-by-step process that, in combination with an exposure analysis and other elements, provides an estimate of the likelihood that an adverse health event will occur as a result of ingestion, inhalation, or absorption of one or more toxins. One of the most important aspects of risk assessment is toxicity assessment.
A toxicity assessment is a study of a substance’s ability to cause harm – and how much harm it can cause. It’s important to note that not all substances are toxic – many therapeutic medications are acute toxic but beneficial when taken at the right dose.

Darwin presented a hypothesis about how evolution takes place. Now this hypothesis has become a theory. What caused the idea to become a theory? A. Darwin shared his ideas with others, and many scientists have performed experiments that support this idea. B. Darwin is well respected, and scientists honor his work by referring to his idea as a theory. C. Darwin performed an experiment that supported his hypothesis. D. Darwin convinced everyone around him that it was a good idea.
Answer:
C. Darwin performed an experiment that supported his hypothesis.
Explanation:
Darwin believed that his experiment, which was comparing the finch's beaks from Galapagos Archipelago, in which there was variation between the size and shape of beaks, as the basis in which he believed evolution was correct. However, variation does not mean evolution, and evolution, in which it calls for a chain of events to create beneficial traits successively, is nigh impossible to occur in the real world. Again, that is not to say that there is no such thing as variation, in which there is, in which people or animal groups adapt to their natural habitat. However, to state that adaptation is proof that a species becomes another is to go out on a limb, and current failures of "new species" (in that it originates from today's day and age, rather then discovered) to emerge is proof of such.

A microbiologist is conducting a research project on chemolithoautotrophs. This means that the investigator is examining certain aspects of a bacterium that is a purple nonsulfur bacteria which depends on light. uses light as its energy source and carbon for organic compounds. can oxidize inorganic molecules such as ammonia and sulfur for energy. can use the energy from sunlight to build organic molecules from carbon dioxide. obtains carbon from organic molecules.
Answer:
uses light as its energy source and carbon for organic compounds.
Explanation:
The purple non-sulfur bacteria which depends on light produces organic food just like plants through the process of photosynthesis. The purple non-sulfur bacteria uses carbondioxide and water with sunlight produces oxygen and glucose which is an organic compound. So that's why purple non-sulfur bacteria is also known as phototrophic means organism that produces their own food through photosynthesis.
Suppose beak size currently ranges from 6-10mm. If directional selection favors larger beaks (up to a max of 15mm), which statement is true?

Which phase of the cell cycle is the least common process of mitosis and what could be the reason?
Answer:
In anaphase, the shortest stage of mitosis, the sister chromatids break apart, and the chromosomes begin moving to opposite ends of the cell. By the end of anaphase, the 2 halves of the cell have an equivalent collection of chromosomes. In telophase, 2 daughter nuclei form. The nuclear envelope beings to reappear.

Postpartum urinary retention can be caused by: a. Stretching of the ureters during delivery b. Decreased sensitivity to bladder fullness c. Contraction of bladder muscles caused by oxytocin d. The effects of proteinuria and lactosuria on the bladder
Answer:
a. Stretching of the ureters during delivery
Explanation:
Postpartum urinary retention is defined as the stretching if the uterus or the genitourinary tissue which occurs in most of the women during vaginal deliveries. The postpartum bladder is vulnerable to the urinary retention. This occurs due to the physiological changes in the pregnancy period. During delivery through vagina, the genitourinary tissues becomes edematous and also gets traumatized form the labor process and thus stretches the ureters during the delivery time. But it returns to normal after 4 to 6 days of diagnosis.
Hence the correct option is (a).
Every day we make choices that can potentially affect our environment. For example, we may toss a plastic drink bottle into the nearby trash because it’s more convenient than walking all the way to the recycling bin. Think about three choices you made this week that could have affected the environment. Did your choices have a positive or a negative effect on the environment? Explain your reasoning.
The three choices that could have affected the environment are as follows:
Utilization of plastic to make it easy for carrying objects.Plants trees in order to build a green environment. Overdependency on vehicles rather bicycles and pedestrians. What is Environment?The environment may be defined as anything which is present in the surroundings of living organisms. This environment basically has two types of factors biotic and abiotic factors.
In the above three choices, building a green environment has a positive effect on the environment. It may also affect living organisms positively. While the rest of the two may stimulate a negative impact on the environment by increasing the levels of carbon dioxide by liberating emission and non-biodegradable plastics.
Therefore, the three choices that could have affected the environment are well mentioned above.

Imagine a continuation of the experiment described above. How might NS3/4A expression impact Sendai virus replication, as measured by the amount of virus produced by the different cells? a. Cells expressing NS3/4A will produce more Sendai virus than cells that do not express NS3/4A. b. Cells expressing NS3/4A will produce less Sendai virus than cells that do not express NS3/4A. c. The two types of cells will produce roughly equal amounts of Sendai virus.
Answer:
The correct answer is - a. Cells expressing more NS3/4a will produce more Sendai virus than cells that do not express NS3/4a.
Explanation:
NS3/4a is a multiprotein serine protease that is a non-covalent heterodimer consisting of a catalytic subunit protein. This heterodimer has an N-terminal one-third of NS3 protein and at an activating cofactor (NS4A) protein.
It acts as an antagonist for cytokine promoters. Thus in the absence of cytokines or reduced levels of cytokines due to inactive promoters) the expression of the virus would increase.

Describe the relationship between the surface area and the volume of a cell. Analyze the data and explain why cells are often flattened instead of cube-shaped.
Answer:
Inverse relation.
Explanation:
There is an inverse relationship between the surface area and the volume of a cell because one increases the other decreases. When a cell grows bigger in size, its internal volume enlarges and the cell membrane start expanding. Unfortunately, the volume increases more rapidly than the surface area of the cell. So the surface area available to pass materials to a unit volume of the cell steadily decreases. Cells are often flattened instead of cube-shaped because the surface area increases. Due to surface area increases, more materials to be absorbed through the cell membrane at a greater rate than that of a cell with smaller surface area.
Mode of action of aldehydes and Quaternary ammonium compounds is
Answer:
Aldehydes have antibacterial, antifungal, antiviral and sporicidal activity. These are helpful to destroy the spores of Bacillus subtilis and Clostridium sporogenes. Glutaraldehyde and formaldehyde are commonly used aldehydes in disinfectants.
Quaternary ammonium compounds work by denaturing the proteins of the bacterial or fungal cell, affecting the metabolic reactions of the cell and causing vital substances to leak out of the cell, causing death.
