Why is botulism so rare? Spores are not killed by boiling, but botulism is uncommon because special, rarely obtained conditions are necessary for botulinum toxin production from C. botulinum spores, including an anaerobic, low-salt, low-acid, low-sugar environment at ambient temperatures. Can you survive botulism? Although botulism can cause severe and prolonged symptoms, most people recover […]

What does less than mean in math terms? Less than is one of the terms used to show the relationship between two values. It states that one value is lesser than the other. The sign for less than is < and with this metric, we can compare numbers, weights, heights, and values. For example, there […]

Which coral reefs are in danger? Almost 95% of coral reefs in Southeast Asia are threatened. Indonesia has the largest area of threatened coral reefs, with fishing threats being the main stressor on coral reefs. More than 75% of the coral reefs in the Atlantic are threatened. How do humans impact the coral reef? Pollution, […]

Is python bite poisonous? It is a non-venomous constrictor, with adults averaging 3–6 m in length. They reside in forests and nature reserves and occasionally venture into the sewer system. They are usually spotted in large drains and at construction sites. Python bites are rare, with 1–2 cases reported a year. Can you survive an […]

What is the final velocity in free fall? Near the surface of the Earth, an object in free fall in a vacuum will accelerate at approximately 9.8 m/s2, independent of its mass. With air resistance acting on an object that has been dropped, the object will eventually reach a terminal velocity, which is around 53 […]

Why is universal health care bad? What Are the Disadvantages of Universal Health Care? A common criticism of universal health care is that the overall quality and variety of care declines. In some countries with universal health care, patients see long wait times or even have to wait months to be seen at all. Universal […]

What are 4 reasons cells divide? Terms in this set (4) Food, Waste, and Gas Exchange. They need to maintain a workable ratio of surface area to volume to allow an efficient transfer of materials in and out of the cell. Growth. In order for an organism to grow, they must divide so they can […]

Why is MMHG used? MmHg means millimetres of mercury (Hg = mercury) and is used in EU member states and Switzerland to measure the pressure of body fluids, such as eg blood pressure. It goes back to a time when pressure was measured by means of a mercury column. How do you convert mm Hg […]

How long do coals burn for? about 1 hour Why do coals burn hotter? Coal and charcoal burn much closer to the source and keep the heat more concentrated leading to a higher temperature. The last thing to happen is combustion of the solid fuel, which is the glowing coals, which gives off the most […]

What is Biot Savart law and its application? The Biot Savart Law states that it is a mathematical expression which illustrates the magnetic field produced by a stable electric current in the particular electromagnetism of physics. This law is applicable in the magnetostatic estimate, & is reliable by both Gauss’s (magnetism) and Ampere’s (circuital) law. […]
