Darwin' theory is that life changed or evolved through a process called natural selection. The theory is sometimes described as "survival of the fittest," but that can be misleading, Pobiner said. Here, "fitness" refers not to an organism's strength or athletic ability, but rather the ability to survive and reproduce.Darwin also described a form of natural selection that depends on an organism's success at attracting a mate, a process known as sexual selection.The colorful plumage of peacocks and the antlers of male deer are both examples of traits that evolved under this type of selection.Darwin didn't know anything about genetics, Pobiner said. "He observed the pattern of evolution, but he didn’t really know about the mechanism."That came later, with the discovery of how genes encode different biological or behavioral traits, and how genes are passed down from parents to offspring.The incorporation of genetics and Darwin's theory is known as "modern evolutionary synthesis."
An multicellular-organism. Well every living thing is made out of cells. So I suggest very big plants animals or humans. Hope i helped! Mostly a multicellular-organism. A living thing with more than one cell.
What is red marrow hyperplasia
natural selection
Biogeographic observations indeed suggest that a evolutionary process caused new species to arise, through the process we call natural selection. This is due to an animals adaptability in it's environment.
That they have a common/similar ancestor. This means that before, possibly these animals came from a similar organism.
These three ideas seem to run together, so it's important that you are able to distinguish among them. The theory that organisms change over time is evolution. The mechanism by which organisms evolve is natural selection. Survival of the fittest explains how natural selection works.Answer = Natural SelectionThe process of natural selection, of course.

Algae is an important organism to both freshwater and marine ecosystem... for it is the primary food of fishes...
I wouldn't suggest it. But if it is completely necessary then you will need to use more baking powder than what the recipe calls for in yeast. NO! They are not interchangable at all! You would have to make a major modification to the recipe, both ingredients and process, to get something close. Yeast is a living organism that creates gas as part of the fermentation process. Baking soda just creates gases when combined with acids.
Acid fast organism in sputum suggest that the patient is having the pulmonary tuberculosis. This is potentially treatable condition. When this organism is found in skin scrapping, it indicates that the person may have leprosy. This is mild disease of low virulence. In both the cases you have to take treatment for long period.
As the name suggest, is a process of creating the enabling and fundamental guideline for the maximum achievement of citizen interest. As a process , logical steps are taken.
There have been a few studies that suggest fig leaves are very toxic and fatal to cats or dogs. Studies have shown that in fact they are fatal to any living organism.
What realistic process could be used to neutralize the river? Explain how the process you suggest would improve conditions.
It is believed so, we were not there so we can't tell for sure but the initial elements required and the simplicity of the first organism (if you can call them organism at this point) suggest us that life most likely bagan in the sea...or any water pool there was back then.
