Does playing a record at the wrong speed damage it? Playing vinyl records at the wrong speed does not do any damage. The audio will not sound as intended, but there will be no lasting extra damage if the standard RPM speeds are used. Can you skip songs on vinyl? A very common question that […]
Where does the carbon cycle start?
Where does the carbon cycle start? Carbon moves from the atmosphere to plants. In the atmosphere, carbon is attached to oxygen in a gas called carbon dioxide (CO2). Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth. Carbon moves from plants to animals. […]
What determines the sequence of amino acids in a protein?
What determines the sequence of amino acids in a protein? The sequence of amino acids are determined by the genetic code. The triplet of nucleotides in tRNA which are complementary to the base pairing of specific triplet nucleotides (codons) in mRNA during the translation phase of protein synthesis. The DNA determines the genes of a […]
Can you hit a 100 mph fastball?
Can you hit a 100 mph fastball? A 100-mph fastball reaches home plate in under 400 milliseconds. The swing itself takes about 150 milliseconds. As popular as they’ve become, 100-mph fastballs are still pretty rare—rare enough that you’re not going to face off against them regularly at batting practice. What is the world record fastest […]
Which malaria parasite has longest incubation period?
Which malaria parasite has longest incubation period? The incubation period in most cases varies from 7 to 30 days. The shorter periods are observed most frequently with P. falciparum and the longer ones with P. malariae. Which of the following is the most effective control for malaria?

Substance Helium Molecular formula He Thermal conductivity (W m−1K−1) 0.153 Specific heat (J K−1kg−1) 3116 2.47 What is viscosity in liquids? Viscosity, resistance of a fluid (liquid or gas) to a change in shape, or […]
Is iodine a solid liquid or gas?
Is iodine a solid liquid or gas? As a pure element, iodine is a lustrous purple-black nonmetal that is solid under standard conditions. It sublimes (changes from a solid to a gaseous state while bypassing a liquid form) easily and gives off a purple vapor. Although it is technically a non-metal, it exhibits some metallic […]
Will Pluto eventually collide with Neptune?
Will Pluto eventually collide with Neptune? Since Pluto and Neptune cross orbits, is it possible that the two planets will collide? No, they actually can’t collide because Pluto’s orbit takes it much higher above the Sun’s orbital plane. When Pluto is at the same point as Neptune’s orbit, it actually much higher up than Neptune. […]
What skin receptors are activated while holding hands?
What skin receptors are activated while holding hands? Touch, Thermoception, and Noiception. A number of receptors are distributed throughout the skin to respond to various touch-related stimuli (Figure 1). These receptors include Meissner’s corpuscles, Pacinian corpuscles, Merkel’s disks, and Ruffini corpuscles. What are examples of sensations? The physical process during which our sensory organs—those involved […]
