Some may argue murder is ok whenever the person deserves it. Like death row… Or back in the 1800’s when people would have hangings of convicts as means of entertainment. But what about innocent life? On my subject the question isn’t whether the life is innocent, but is it living? Abortion; one of the most controversial subjects of all time. Is it right? Who’s to say its wrong? When does life start; conception, after the vitals work or at birth? If you study every organic substance… plants, animals, humans, and microscopic organisms; we would agree that these things do live and eventually they die. So let’s question conception. A sperm cell and an egg cell both cells both living. During conception a sperm fertilizes an egg… not soon afterwards it becomes a zygote. Are zygotes living? Yes. Because how can a dead cell multiply itself against itself; from 1 to 2, 4, 8, and 16 and so on until that one alive cell multiplies into billions and billions of other living cells. So since life is present due to the living cells; the question now is time. Well, what time should I get rid of this before I feel like I’m killing something? Time; is only a symbol. What is time? Your time is your life. Time is life and life is existence so who’s to say the zygote that spent time in your womb, isn’t existing? I keep hearing people say we should respect the “potential” life of unborn babies. Why should respect potential life when the cells are already living?

i have to do a "background of subject under study" on my lab report, and my lab was different wavelengths (colors) and its affect on photosynthesis. what would i say about the background (i am terrible at biology)? Would I just say

"Higher wavelenghts of light are absorbed, which increase the action of photons. The higher the wavelength, the more light is absorbed, which increases the rate of photosynthesis as compared to lower wavelengths."

G proteins and G-protein-linked receptors
are not widespread in nature and were unimportant in the evolution of eukaryotes.
are found only in animal cells.
probably evolved from an adaptation of the citric acid cycle.
are thought to have evolved very early, because of their similar structure and function in a wide variety of modern organisms whose common ancestors diverged billions of years ago.
