Based on population data, the three cities with the largest populations in South America are:
1. São Paulo
2. Buenos Aires
3. Rio de Janeiro
Please note that the exact rankings can vary based on different sources and the year of the data used.

Yes, based on available data up to 2023, São Paulo, Buenos Aires, and Rio de Janeiro are generally recognized as the three largest cities in South America by population. São Paulo is the largest, followed by Buenos Aires and then Rio de Janeiro. However, for the most precise and current figures, specific population statistics or census data would provide the best confirmation.
How Light Affects Rate of Photosynthesis - MUST READ CAREFULLY
BACKGROUND: Photosynthesis takes place in green plants in specialized structures called chloroplasts. For photosynthesis to occur, the chloroplasts must be exposed to sufficient light. Today's sample work will examine whether the amount of light can have an impact on how quickly photosynthesis takes place.
The green plant used in the videos is called elodea. It is important to note that some types of elodea are invasive, so stores in South Carolina are legally limited regarding the sale of elodea. Most stores in our state will not sell any type of elodea because it is very easy to mix up the invasive type with the noninvasive type. If you ever encounter elodea from a pet store, it is very important that you dispose of it properly. Elodea should be sealed in a plastic bag and frozen for at least 72 hours before discarding in a proper trash receptacle, still sealed in the plastic bag.
Refresh your memory regarding the chemical equation that summarizes the process of photosynthesis. As a reminder, reactants are on the left side of the equation, and products are on the right side of the equation.
For this experiment, pieces of elodea have been placed in water that was aged (allowed to sit for a few days so the chlorine in it will evaporate away) and treated with baking soda (so it will have plenty of carbon dioxide). For the first part of the experiment, the elodea will be in a low light condition. For the second part of the experiment, the elodea will be in a high light condition. In both cases, as the plant absorbs sunlight, it will perform photosynthesis. Oxygen gas bubbles will be released, especially from the stem (due to the plant's orientation in the water). The rate at which oxygen gas bubbles are produced is an indicator of how quickly photosynthesis is taking place.
EXPERIMENTAL QUESTION: How will changing the amount of light affect the rate of photosynthesis?
HYPOTHESIS: Increasing the amount of light will increase the rate of photosynthesis.
MATERIALS: beaker, lamp, elodea plant, aged tap water with baking soda added, timer
Question
1. Which prediction for the number of bubbles produced best matches the stated hypothesis?(1 point)
Responses
The low light condition is predicted to result in more bubbles than the high light condition.
The low light condition is predicted to result in more bubbles than the high light condition.
The high light condition is predicted to result in more bubbles than the low light condition.
The high light condition is predicted to result in more bubbles than the low light condition.
The low light and high light conditions are predicted to produce the same amount of bubbles.
The low light and high light conditions are predicted to produce the same amount of bubbles.

Based on the stated hypothesis that increasing the amount of light will increase the rate of photosynthesis, the prediction that best matches this hypothesis is:
**The high light condition is predicted to result in more bubbles than the low light condition.**
This aligns with the expectation that more light will enhance photosynthesis and therefore increase the production of oxygen bubbles.
**The high light condition is predicted to result in more bubbles than the low light condition.**
This aligns with the expectation that more light will enhance photosynthesis and therefore increase the production of oxygen bubbles.
