It is estimated that the agriculture was invented 10000 to 12000 year ago. At this period of time, the modern humans or the <em>Homo sapiens</em> were spread to America.
The <em>Homo sapiens</em> begin to form villages and started domesticating animals. Also, all other ancestors of humans were possibly dead up to this period. The agriculture developments and advancements occurred after 10000 year ago.
Hence, the correct answer is <em>Homo sapiens. </em>
<span>Within the water cycle, the water within the ocean evaporates and is converted into a gaseous form before it is able to enter the atmosphere (Answer A). High in the atmosphere, the water then cools and condenses, forming water clouds that eventually rain back to the ground and ocean. </span>
Nope! The genome is the entire set of genetic material in an organism. The genome is made up of all the DNA inside an organism.
One cardiac cycle is .8 seconds. A complete heartbeat is produced in one cardiac cycle. <span>The period of time that begins with contraction of the atria and ends with ventricular relaxation is known as the cardiac cycle. The period of contraction that the heart undergoes while it pumps blood into circulation is called systole.</span>
<span>The main reason surface area to volume ratio is important to a cell is because the surface area to volume ratio determines the rate at which cells uptake nutrients, liquids or gases. For instance, I have two organisms, A and B. Organism A has a surface area to volume ratio of 6:1, whereas organism B has a surface area to volume ratio of 3:1. As organism A has a greater surface area to volume ratio, it means that organism A will be able to take up nutrients, liquids or gases via diffusion or osmosis at a greater rate than organism B, as it has more surface with which to exchange nutrients, liquids or gases. </span>
