What is a Type 3 curve? The Type III curve, characteristic of small mammals, fishes, and invertebrates, is the opposite: it describes organisms with a high death rate (or low survivorship rate) immediately following birth. In contrast, the Type II curve considers birds, mice, and other organisms characterized by a relatively constant… What animals have […]

Is it safe to breathe in ozone?
Is it safe to breathe in ozone? When inhaled, ozone can damage the lungs. Relatively low amounts can cause chest pain, coughing, shortness of breath and throat irritation. Ozone may also worsen chronic respiratory diseases such as asthma and compromise the ability of the body to fight respiratory infections. Can ozone cure Lyme disease? Ozone […]
When we stop pedaling a bicycle it comes to rest after sometime describe the forces responsible for the change in state of motion of the bicycle?
When we stop pedaling a bicycle it comes to rest after sometime describe the forces responsible for the change in state of motion of the bicycle? Solution. If we stop pedalling a bicycle, moving at a uniform speed, it does not go on moving forever. It eventually comes to rest after some time. This is […]
What is the level of intensity of your physical activity in general?
What is the level of intensity of your physical activity in general? Typically, the intensity of physical activity can be described as light, moderate or vigorous. To benefit health, Australia’s Physical Activity and Sedentary Behaviour Guidelines recommend a variety of moderate and vigorous intensity physical activity. What is RPE level? Perceived Exertion (Borg Rating of […]
What is the half life of a first-order reaction if time required to decrease?
What is the half life of a first-order reaction if time required to decrease? Concentration is reduced to 25%. It means it takes two half-lives to decrease the concentration of reactant from 0.8 M to 0.2 M in first-order reaction. Hence, half-life of the reaction is 12/2 = 6 hours. The half life of reaction […]

Why should foods be refrigerated?
Why should foods be refrigerated? Refrigeration slows bacterial growth. Bacteria exist everywhere in nature. They are in the soil, air, water, and the foods we eat. When they have nutrients (food), moisture, and favorable temperatures, they grow rapidly, increasing in numbers to the point where some types of bacteria can cause illness. What is the […]
