Answer:
See Below.
Explanation:
The key word here is <em>net. </em>The net movement has reached zero when a system is in equilibrium but there are still motion's going back and forth due to statistics and just random brownian motion.
Think of it this way, if there are 100 people walking forwards in a crowd but 2 are moving against the crowd, the net movement is still forwards because the bulk of people are going in that direction. However, there are still 2 people moving against.
Same here, if we are talking about a diffusion, let's say in the case of osmosis, if most of the solute is moving across a membrane then we'd say its net direction is that way but that doesn't mean that there aren't processes happening in the other direction. Water molecules in osmosis mostly diffuse, chemically speaking (because you can say this biologically in a different way), from the probability of water molecules colliding with each other and passing the membrane so even if there is a net movement in a certain way their random motion can make them go to the other side just as well. If the fact that motion stops at equilibrium were the case a lot of systems, both chemical and biological, would not exist as we know it.
Think net = bulk <u>NOT</u> <em>total</em> or <em>entire.</em>
Answer:
Lack of gravity causes you to use less work to move your muscles.
Explanation:
If on Earth your arm weighs 3 pounds, the muscle will only have to move 3 pounds of force. For example, if you were to go on the moon, your arm would have the same mass but there would be less gravity pulling it dow. So now your muscles only need to pull 1 pound. Over extended periods, you would be working less, thus not using your muscles to fullest potential and in result you would get weaker.
Heavy metals work by dissolving the cell wall.
Sterilization describes a method that destroys or gets rid of all styles of microbial existence and is done in health-care facilities with the aid of bodily or chemical strategies. Using a physical or chemical method to smash vegetative pathogens is: disinfection. using chemical marketers immediately on uncovered frame surfaces to damage or inhibit vegetative pathogens.
The term heavy metallic refers to any steel chemical detail that has a notably excessive density and is poisonous or toxic at low concentrations. Examples of heavy metals encompass mercury (Hg), cadmium (Cd), arsenic (As), chromium (Cr), thallium (Tl), and lead (Pb). Even though the beginning of the time period heavy metallic is broadly attributed to novelist William Burroughs, its use dates nicely again into the nineteenth century, while it cited cannon or to electricity greater usually. It additionally has been used to classify certain elements or compounds, as in the phrase heavy metallic poisoning.
