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.
Answer:
The chloroplasts in autotrophic organisms (most often plants and algae) capture energy from the sun.
Explanation:
The chloroplasts take in this energy from the sun, and converts it into energy called ATP through the process called photosynthesis.

The answers are B and C because the other 2 are unhealthy
Answer:
The effect might be due to the gene expression.
Explanation:
The effect might be due to the variation in the gene expression in the organism. In this way, the variety of the genetic pool is likely to result in a diversity of the gene pool or genome. Because of the mutation and the environmental factors, there is likely to be a slight variation of the species. This results in a slight difference in the phenotypic expression.
Answer:
d They usually have certain special functions
Explanation:
a) They can all turn into the same kind of cell needed - this is false. Cells in a multi cell organism such as humans cannot turn to any type of cell, this functionality is called pluripotency, and only exists in specialised cells called stem cells. These cells are present early in development, and in some tissues where cells are replaced frequently, like the cells of the gut.
b) They are all identical - this is false. Although they all carry the same genetic information, the cells in a multicell organism are usually very different, carrying out different functions. E.g. the cells of the skin are very different from the cells of the blood.
c) They are prokaryotic cells - this is false. All prokaryotic cells are single celled organisms, only eukaryotic cells can form part of multi cell organisms
d) They usually have certain special functions - this is true. Cells in a multicell organism usually perform different functions in order to contribute to the entire organism. For example, the function of the cells in the heart is very different from the function of the cells in the brain.
