Answer:
Some species that already have or that developed cold-weather adaptions through natural selection will survive, while species without cold-weather adaptations may go extinct.

PGA
RuBP
NADPH
PGA (phosphoglycerate) is a metabolic intermediate of the light-independent reactions in photosynthesis. Therefore, the correct statement is option B.
A metabolic intermediate in photosynthesis's light-independent reactions, also known as the Calvin cycle, is PGA (phosphoglycerate). The Rubisco (ribulose-1,5-bisphosphate carboxylase/oxygenase) enzyme is responsible for fixing carbon dioxide into PGA during the Calvin cycle.
After that, PGA is transformed into other compounds like glyceraldehyde-3-phosphate (G3P) and glucose, which can be stored in plant tissues or used as energy.
The Calvin cycle gets its energy and reducing power from the light-dependent reactions in photosynthesis, which produce ATP and NADPH. RuBP (ribulose-1,5-bisphosphate) is the underlying carbon dioxide acceptor atom in the Calvin cycle.
Therefore, PGA (phosphoglycerate) is a metabolic intermediate of the light-independent reactions in photosynthesis.

The metabolic intermediate of the light-independent reactions in photosynthesis is PGA (3-phosphoglycerate).
In photosynthesis, the light-independent reactions, also known as the Calvin cycle, occur in the stroma of chloroplasts. One of the metabolic intermediates produced during this process is PGA (3-phosphoglycerate). It is formed as a result of the incorporation of carbon dioxide into a five-carbon molecule called RuBP (ribulose 1,5-bisphosphate). PGA is then converted into other compounds, such as glucose, during subsequent steps of the Calvin cycle.
PGA is produced during the carbon fixation step of the Calvin cycle and is eventually used to generate sugars and other organic molecules in the process of photosynthesis.

Answer:
Seepage; runoff
Explanation:
In nature, water is constantly circling: from the water surfaces it evaporates, travels up in the atmosphere, there it condensates, forms clouds, and then again falls to the land and water surfaces. This cycle has been going on for thousands and thousands of years and is known as the water cycle.
Now, the real question is how does the water, fallen from the clouds, on the land, travel back to the oceans.
Soil consists of multiple layers, some are water permeable, and some are not. When water (rain) reaches the soil, through tiny pores in upper permeable layers it will travel downward, deeper and deeper. This process is called the seepage. Upon reaching the water-impermeable layers, it stops, becoming part of what is known the underground water. It will continue to flow on this layer until it finds its way back on the surface, usually in a form of a spring, which will find its way to a river, and river will take that water to a sea or an ocean.
However, if the soil is to saturated with water, especially during long rainy, stormy period, or in the spring, after the snow melts. This excess water will, because of the gravity, flow over the earth's surface, from higher (mountains) to lower (valley) areas, making its way to some valley river, which will take it further to a sea or an ocean.
Upon reaching the ocean, this land-water can again join the water cycle, again and again.
