Answer:
Small uncharged polar molecules, such as H2O, also can diffuse through membranes, but larger uncharged polar molecules, such as glucose, cannot. Charged molecules, such as ions, are unable to diffuse through a phospholipid bilayer regardless of size; even H+ ions cannot cross a lipid bilayer by free diffusion.
Explanation:
Answer:
The correct answer is - Observations generate a scientific question, leading to a hypothesis, which can be tested through an experiment.
Explanation:
In any scientific knowledge development process, scientists need to follow the scientific process in a particular sequence that helps in developing and testing a hypothesis.
The sequence has:
observation: Observation requires you to pay attention to occurrences around
Forming question: on the basis of observation form a question about why that occurrence happens.
Hypothesis formation: The hypothesis is your initial prediction on why that happens.
Experiment: The experiment is being done in order to collect data and analysis so you can test your hypothesis
H20 tends to evaporate quicker in 80 degrees or higher, evaporation in colder weather, is much slower.
Biodiversity affects humans by: underpins the health and has a direct impact on all of our lives. To summarize reduced biodiversity means millions of people face a future where food supplies are more vulnerable to pests and disease, and where fresh water is in irregular or short supply. For humans that is worrying.
The reason it's so important is because say you were doing push ups. Most people hold their breath will doing any exercise, and that is really bad for you. The reason why you have to exhale completely is because if you don't, you can/will pass out because your brain won't have enough oxygen to pass down for your muscles to work properly.
