Answer: C. Microevolution is small scale change to the gene pool of a population while macroevolution is larger scale changes that lead to speciation.
Explanation:
Microevolution can be defined as a small change in the gene frequency within a gene pool of the species, these changes will be inherited by the organisms and there will not be any drastic change at the species level. But in case of macroevolution the large scale change occurs at the genetic level, which retain for long. This leads to development of new organisms or results in speciation.
Industrial waste! This is because the waste is in direct contact with the soil in the form of chemicals or even heat!
The most probable future changes in the global climate are:
- Global warming;
If the levels of CO2 and methane increase enough in the atmosphere to be able to intensify the Greenhouse effect, than some portion of the ice on the planet will melt because of the rising temperatures, thus lifting up the sea level, creating more unpredictable weather with larger and stronger storms, but also making the mainland much drier. This would be a scenario if the continents are arranged like they are now, but if there isn't a sufficient mass of land on and around the poles, than all of the ice will melt and the sea levels will rise so much that the planet will come in the ''water planet'' scenario, and it will have wet tropical climate pretty much everywhere on the planet.
- Ice Age;
If there's a disruption in the warm ocean streams and some of them disappear, or the levels of nitrogen or oxygen increase in the atmosphere, the Earth will start to cool off, thus coming to a situation of an Ice Age. In this kind of situation, there will be large ice sheets on and around the poles that are stretching much further towards the lower latitudes, as well as mountains all over the world that are covered in snow and shaped by glaciers.
Explanation :

F. Sites of photosynthesis<u> - chloroplasts</u>
G. Regulates water levels in plant cells <u>- vacuole</u>
H. Used in break down of fats and contains the enzyme catalase - <u>peroxisome</u>
Answer:
If you consider the particles of each state of matter, it becomes evident that pressure and temperature are the major factors that affect the transitions of matter.
Temperature can cause molecules to move slower or faster.
Pressure can cause molecules to become more or less packed together.
