Before the marble starts rolling, it is potential energy. Once it is rolling, it is kinetic energy. You know it stays the same because the marble probably would not be rolling if it weren't. All that's happening is that the ball is rolling faster because of gravity.
<span>Gravity assists the marble, leading to conservation of energy. The
stored energy is release as momentum, the output of energy is constant.</span>
To protect our eyes from moisture and light. Example: from sweat. It can also reduce the amount of light that gets in your eyes and keep dirt away from them too.
A. Osmosis has to occur through a semi-permeable membrane whereas diffusion can occur through any concentration gradient.
B is incorrect because net movement of osmosis is from area of low concentration to area of high concentration.
C is incorrect because both diffusion and osmosis is a form of passive transport
D is incorrect because the descriptions of osmosis and diffusion are swapped
It depends on the individual reaction to lactose. first, some individuals are considered lactose intolerant meaning they lack enzymes that break down lactose into glucose and galactose. hence, if they digest dairy products they can have severe symptoms that will affect their health. however individual who aren’t lactose intolerant benefit from digesting lactose containing products because it improves the individuals health by providing the body with sufficient amount of energy when lactose is broken down to glucose and galactose. Also, consuming Foods in the Dairy Group provide nutrients that are vital for health and maintenance of the body. over all, it all comes down to how an individual will react to such decisions when eliminating lactose. If this decision outweighs the disadvantages then I agree with it however if it doesn’t I completely disagree
