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.
Answer:
Natural selection is one of the mechanisms by which an organism evolve. In the natural selection when the trait of an organism allows the organism to grow and reproduce in an environment and nature selects it, it is then passed on to the generations and become permanent.
Artificial selection is also one of the mechanism of evolution in which instead of nature, the selection is made by humans like the breeding experiments on dogs and plant crops.
The artificial selection and natural selection are interlinked as in the artificial selection the trait selected by the humans were also selected by nature like the case of crops, the crossing between desired plants produced results which were useful to the humans but grew and reproduced only when the environment selected it to grow and reproduce.
Answer:
B
Explanation
They have to realease things somehow
The systems are:
Nervous system: this is because the brain sends out commands to the body or it signals other parts which makes your body move like walk or to pick something up.
Muscular system: the muscular system such as your bones and muscles is what keeps the bones together so you could move/walk.
Hope this helped :)
Have a great day
This can be answered by asking why do we all have different skin colours: Melanin pigmentation. Years of evolution made different people around the worrld different skin colours as an protective mechanism against high levels of UVR exposure, the closer people were to the eqautor, the hotter it would be, so many people living in tropical and desert like climates had darker skin. To answer about folate though, people are darker skin tones living near the equator had dark skin to prevent folate deficiency. So yes everyone has folate, but some people are darker skin to better protect it and their skin.
Hope this helps, HAVE A BLESSED AND WONDERFUL DAY! As well as a great Superbowl Weekend! :-)
