What are the disadvantages of Daylight Savings Time? 1. Changing the time, even if it is only by an hour, disrupts our body clocks and rhythm. According to officials, the lack of sleep at the start of DST has lead to car accidents, workplace injuries, suicide and miscarriages. The risk of suffering a heart attack […]
How are electric charges created?
How are electric charges created? A. Electrons can be removed from atoms and accumulated to produce a negative charge. Atoms from which electrons have been removed produce positive electric charge. … What is range of electric force? The electric force is operative between charges down to distances of at least 10-16 metre, or approximately one-tenth […]
How do plants return water back into the environment?
How do plants return water back into the environment? Plants soak up large amounts of water through their roots. The water then moves up the plant and evaporates from the leaves in a process called transpiration. The process of transpiration, like evaporation, returns water back into the atmosphere. What’s it called when plants lose water […]
Can you use a 50mm lens for macro?
Can you use a 50mm lens for macro? 50mm lenses work best in capturing typical macro shots. However, these types of macro lenses have their drawbacks. 50mm lenses make subjects appear half “life-size” since they usually feature a 1:2 ratio, and require shooting at a much closer distance. But a 50mm lens is a must […]
What is the life expectancy of someone with brittle bone disease?
What is the life expectancy of someone with brittle bone disease? Can brittle bone disease be cured? Brittle bone disease has no cure. The prognosis for infants with the most severe form of osteogenesis imperfecta is poor, and most children may not live beyond a few weeks. What is the fastest way to increase bone […]

What is the relationship between osmosis and diffusion?
What is the relationship between osmosis and diffusion? Osmosis only allows solvent molecules to move freely, but diffusion allows both solvent and solute molecules to move freely. 4. Osmosis happens when molecules move from higher to lower concentrations, but diffusion happens when it is reversed. Is osmosis active or passive? Osmosis is a passive transport […]
Which mechanisms of heat transfer will work in a vacuum quizlet?
Which mechanisms of heat transfer will work in a vacuum quizlet? a. Yes, heat transfer by conduction will occur through a vacuum. Which heat transfer process is increased by profuse sweating? Convective heat exchange increases with increasing air speed and increased differences between air and skin temperature. Evaporation of sweat from the skin cools the […]
What is the difference solution and suspension?
What is the difference solution and suspension? 1. Solutions are mixtures that are homogeneous while suspensions are mixtures that are heterogeneous. 2. The particles of a solution are at the ion or molecular level and cannot be seen by the naked eye while the particles of a suspension can be seen by the naked eye. […]
Why are steam burns more serious than burns caused by an equal amount of equally hot water?
Why are steam burns more serious than burns caused by an equal amount of equally hot water? Steam is more likely to cause burn injuries than boiling water because of the latent heat of vaporization. Since water expands to approximately 1,600 times its volume when it turns from liquid to steam, steam often escapes its […]
