What are 10 examples of prokaryotic cells? Explanation: Escherichia coli bacterium. Streptococcus bacterium. Sulfolobus acidocaldarius archeobacterium. streptococcus pyogenes. lactobacillus acidophilus. Cyanobacteria. Archaea. Is a virus a prokaryote? Prokaryotes include several kinds of microorganisms, such as bacteria and cyanobacteria. Viruses are considered neither prokaryotes nor eukaryotes because they lack the characteristics of living things, except the […]
Why does force act on a wire?
Why does force act on a wire? A wire carrying a current creates a magnetic field . This can interact with another magnetic field, causing a force that pushes the wire at right angles. Do magnetic fields affect the brain? According to a new study, humans can also sense Earth’s magnetic field. The new study, […]
Why does helium make things float?
Why does helium make things float? Helium floats because it is buoyant; its molecules are lighter than the nitrogen and oxygen molecules of our atmosphere and so they rise above it. In the car, it’s the air molecules that are actually getting pulled and pushed around by gravity as the result of the accelerating frame. […]

Do animals eat seeds?
Do animals eat seeds? A new study finds that large animals eat not only large seeds but small ones too – helping with seed dispersal. If they become extinct, this could have an impact on overall biodiversity in an ecosystem. Scientists have long thought that small animals eat small seeds and large animals eat large […]

How do you know which LED bulb is bad on Christmas lights?
How do you know which LED bulb is bad on Christmas lights? Simply bring the light tester close to each bulb. The tester’s indicator will light up when it’s near a functioning bulb. If you have a non-contact voltage detector, bring the detector close to the wire section between each bulb to test for voltage. […]
How do you find the uncertainty of a de Broglie wavelength?
How do you find the uncertainty of a de Broglie wavelength? Heisenberg’s Uncertainty Principle. Equation 11.6. 4 can be derived by assuming the particle of interest is behaving as a particle, and not as a wave. Simply let Δp=mv, and Δx=h/(mv) (from De Broglie’s expression for the wavelength of a particle). What would be the […]
Do babies need to wear life jackets on boats?
Do babies need to wear life jackets on boats? Under California law, every child under 13 years of age on a moving recreational vessel of any length must wear a Coast Guard-approved life jacket in serviceable condition and of a type and size appropriate for the conditions and the activity.
