Lipases are likely to be denatured by highly acidic or highly basic pH. Evidence of this is present in the fact that bile is released into the endothelium where the lipases will act in order to neutralize the stomach acids.
Embryonic mass cells are in constant
division, making it much easier to find good examples of each phase of mitosis. The root and the stem are the best place to
look because they contain meristematic tissue that retains the ability to
divide throughout the life of the plant.
Paleontology, the study of fossils, supports evolution because the discovery of old life forms shows how new life evolved.
The answer would be (b) evolutionary species concept.
Well, obviously one would need to start off with a plan. After having an idea/blueprint of what your ideal treehouse will look like try finding some measurements for the wood (or whatever material you will use I won't judge) of course you better already have the length, width, and height of your treehouse. After that, you can get building; which could take days or even weeks depending on the house design and the amount of people you have to help out. Once that's done you can paint and decorate it all you want. (of course, to get it in the tree you might need a pulley to put it up there or build the bottom up on the tree.) And all your missing your ladder and that's it.
