The answer you are looking for is B. Bubbles form when two chemicals are mixed together.
Answer:
B- Photosynthesis
Explanation:
Chloroplasts are <em>chlorophyll-containing, eukaryotic cell structures</em> that function in photosynthesis by absorbing energy from sunlight, combining this energy with water and CO2 to convert them to sugars . This cell structure is known as a plastid. The sugars produced, are important for the survival of the plant.
Chloroplasts reproduce on their own, independent of the whole cell because they contain their own DNA. Plant chloroplasts are located in guard cells in plant leaves. Closely linked to these guard cells are tiny pores called stomata, which allow gas exchange required for photosynthesis.
Photosynthesis occurs in two stages:
- The light reaction stage
- The dark reaction stage
The Light reaction stage takes place in the presence of light. Clorophyll converts light into chemical energy in the form of ATP and NADPH. Both molecules produced, are used in the dark stage to produce sugar.
In the dark reaction stage, the stroma, containing enzymes, facilitates reactions leading to the production of sugars from ATP and NADPH. This process is also called the carbon fixation stage. The sugar produced can be stored in the form of starch for other processes such as respiration.
Answer:
circulatory system
Explanation:
Oxygen and nutrients are taken to body parts by the Circulatory System (also named Vascular System)
This is because if we strictly only allow people or things of our type to mingle, there are not enough of us to keep the population going, because then reproducing would be slower and we'd die out, and it would happen that some people who insist on finding "soulmates" that are perfect for them wouldn't find it in their group and refuse to reproduce, therefore making the population even lower.
