Bacteria to amphibians. amphibians started to turn to fish and some started walking to land. They started laying eggs and turning into reptiles. those reptiles started growing hair turning them into four legged mammals. the mammals then turned to primates which evolved into us.
More than 90% on the crust is composed of silicate minerals. Most abundant silicates are feldspars<span> (</span>plagioclase<span> (39%) and alkali feldspar (12%)). Other common silicate minerals are </span>quartz<span> (12%) </span>pyroxenes<span> (11%), </span>amphiboles<span> (5%), micas (5%), and clay minerals (5%).</span>
1. homeostasis
2. negative feedback loop
3. the hypothalamus
4. the body’s optimal temperature, which is 37 degrees C, or 98.6 F
5. humans are endothermic, which means they don’t completely rely on their environment for heat, unlike ectothermic organisms such as reptiles. the diagram shows that the brain is in control of the body’s temperature, and that the body can raise its own temperature in its blood.
or something like that, hope this helped
