I just learned this in science a month ago! Redi used a piece of meat in a jar and covered it with a cheesecloth. He got another jar of meat and left it open. He wanted to see if magots developed from flies or not. Luis Pasteur used an 'S' tube thingy and put broth inside and boiled it. Then he waited to see if broth fogged up because of dust or microorganisms. One tube was pointed upward so dust could get inside, and the other, downward. Hope this kindof explains this topic to you!
I think the answer is either three or four I am not 100% certain but I feel like the answer for this question is going to be 3
Answer:
For one thing, there's lots more of it. There are many more environmental niches to be occupied in salt-water bodies, and importantly, they're all connected, making it easier for species to migrate and adapt to new habitats. Conversely, fresh-water habitats are often more isolated, confining species to a single habitat and decreasing the likelihood that they'll be able to migrate and adapt.
Explanation:
If a substance is very sour and has a ph of 4, then you would expect the litmus paper to turn into the shade of red. A substance that is sour and has a pH level that is below 7 would indicate that the substance is an acid or has acidic properties. For an acidic solution, the litmus would be red in color. If a blue litmus paper is used, then it would turn into red while if a red litmus paper is used, then it would remain as red. There is also a general type of litmus paper where the color change range from violet to red. A litmus is widely used in distinguishing acid and bases. It can be used in liquid solutions and in gas mixtures. <span />
