Answer:
<em>Increased immigration</em>
Explanation:
Population growth generally refers to increase in population size or the number of individuals in a particular area. Population growth is influenced by four fundamental factors which are;
- Death rate
- Birth rate
- Immigration
- Emigration
While death and emigration negatively affect population growth because individuals are exiting the population, immigration and birth add new individuals into the population and positively affect population growth.
Hence, from all the available options, only increased immigration can lead to an increase in a country's population growth rate.

3-PGA is the important metabolic intermediate in light independent reactions of photosynthesis.
PGA
<u>Explanation:</u>
Light-independent reaction in photosynthesis is called Calvin cycle and the reaction doesn’t directly require sunlight. But it still needs the products of light reaction. In light-independent reaction carbon dioxide is fixed from inorganic form into an organic form.
In the fixation each molecule of carbon dioxide reacts with RuBP and forms two molecules of 3-PGA at a time. The reaction is catalyzed by the enzyme RuBisCO. Since 3 molecules of RuBP are involved a total of 6 molecules of 3-PGA will be formed in fixation.
Here the 3-PGA is the intermediate and in the next stage it will get reduced to G3P(Glyceraldehyde -3 phosphate).
A single variable.
In an experiment we are trying to figure out how one thing (independent) effects another thing (dependent) so we want to keep everything constant. We want that experiment to be controlled so nothing else is effecting our dependent variable. That way we can be 100% sure that any change to our dependent is due to our independent variable. Hope that makes sense
