Answer:
Homology refers to the similarities between the group of species that share the common ancestor. The homology individuals arise from a common ancestor. They shows divergent evolution. The basic structure in homology is similar. The organs perform different function. They occur due to the evolutionary process.
Homoplasy refers to the shared characters of the group of species that do not share the common ancestor. The homoplasy do not involve the common ancestor. They shows convergent evolution. The basic structure in homoplasy is different. The organs perform the similar function. They occur due to the adaptation in different habitats.
Nitrogen takes steps through the Nitrogen Cycle, taking an active role in the lives of organisms and changing forms to meet their needs. In fact, nitrogen is a critical part of the development of plants, many farmers even add nitrogen to plants to make the grow bigger and more fruitful. Even the human body needs nitrogen to, which is good because most of the air we breath is nitrogen.
Answer:
B
Explanation:
Convection occurs to divert heat generated by the core and spread through the mantle. at the bottom of the mantle, heat is gained, causing the mantle to be less dense and rise up. at the top, heat is subsequently lost, resulting in am increase of mass and a drop down for the mantle. this process repeats indefinitely
Global warming is caused by carbon dioxide formed by people which then traps heat in the atmosphere that is like a blanket of heat wrapped around the earth.
Because of this, ice on the polar icecaps are starting to melt causing our ocean water to rise. now if this continues than we are in trouble because a lotttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttt of countries will be underwater and this our fault.
scary i know hopes this help u understand a little about global warming. ;)
I have no idea but I just want some points
