Can mold grow in a vacuum sealed bag? Vacuum-sealed bags keep all air out, which prevents proper ventilation for your clothes. In some instances, this can lead to mold growing in the bags — especially if you live in an area with a lot of moisture in the air. Does vacuum sealing damage clothes? Intensive […]
How much elastic potential energy is stored in the spring?
What are the forces that enable a pendulum bob to swing?
What are the forces that enable a pendulum bob to swing? In pendulum motion, three forces work directly on the pendulum: the mass of the bob, gravity and the tension in the string. Mass and gravity both work vertically downward. Does the pendulum tell the truth? Like muscle testing, your body itself is its own […]
What is the precise meaning of multicellular?
What is the precise meaning of multicellular? : having, made up of, or involving more than one and usually many cells especially of living matter It is probable that with a few exceptions all the cells in a multicellular organism have the same genetic information encoded in the chains of nucleotide bases that make up […]
How dangerous is ground-level ozone?
How dangerous is ground-level ozone? Breathing elevated concentrations of ozone can trigger a variety of responses, such as chest pain, coughing, throat irritation, and airway inflammation. It also can reduce lung function and harm lung tissue. Ozone can worsen bronchitis, emphysema, and asthma , leading to increased medical care . How can ground-level ozone be […]
Is Cos vertical or horizontal?
Is Cos vertical or horizontal? The Sine and Cosine This page contains a more detailed examination of the behavior of the sine (vertical component of the angle or ratio of opposite leg to hypotenuse) and cosine (horizontal component of the angle or ratio of adjacent leg to hypotenuse) functions. Is trigonometry a physics? Trigonometry Is […]
What is the difference between a qualitative and quantitative analysis?
What is the difference between a qualitative and quantitative analysis? Let’s differentiate between the two. Qualitative analysis fundamentally means to measure something by its quality rather than quantity. Quantitative analysis is the opposite; to measure by quantity rather than quality. When we do quantitative analysis, we are exploring facts, measures, numbers and percentages. Why quantitative […]
What is it important to prepare a good bacterial smear?
What is it important to prepare a good bacterial smear? The preparation of a smear is required for many laboratory procedures, including the Gram-stain. The purpose of making a smear is to fix the bacteria onto the slide and to prevent the sample from being lost during a staining procedure. A smear can be prepared […]
Are factors that the experiment is changing?
Are factors that the experiment is changing? The things that are changing in an experiment are called variables. A variable is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables: independent, dependent, and controlled. What part of an experiment does not change? Control […]
What does it smell like when lightning?
What does it smell like when lightning? The smell is probably ozone, which typically has a sweet, pungent aroma. In stormy weather, lightning splits atmospheric nitrogen and oxygen molecules. These can then combine into nitric oxide, which, with further reactions, forms ozone. Can you taste lightning? Though it may sound strange, you may taste something […]
