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.
The correct answer is option C. A leaf growing in full sunlight
The chloroplast is an organelle, which helps the plants to carry out the process of the photosynthesis. The leaves are the main site of the photosynthesis in the plants, hence, they have an abundant number of chloroplasts present in the cells. In the presence of the sunlight, they perform the light dependent reactions of the photosynthesis process. In case, a scientist find out the cell, which have a high number of chloroplast, then the cell must be specialised to perform photosynthesis, hence, the cell would belong to the leaves, which are growing in full sunlight.
The answer is definitely B
Answer:
Hydrogen ions are transported across the thylakoid membrane. Hydrogen ions diffuse through a protein channel.
