Answer:
Bubbles of carbondioxide and oxygen appears on the lower surface of leaf where stomata is located.
Explanation:
During the process of photosynthesis, when carbondioxide react with water in the presence of sunlight produces glucose and oxygen. Glucose is stored in different parts of plant body while oxygen is released in the atmosphere through a tiny holes called stomata. When this oxygen go through stomata, it form bubbles.
Answer: A and D
Because photosynthesis takes in carbon dioxide and releases oxygen for people to breath
Hope this helps you :)
The global air temperature increases after the volcanic eruptions. It has also been observed that this increase in air temperature causes lowered winter seasons, acid rain, haze, dust, and ash. This causes problems in breathing and other disorders in humans as well as animals.
<span>Although a star might look brighter than the Sun, a comparison of its absolute<span> magnitude might help prove that they have the same real brightness.
Absolute magnitude is a concept that compares the absolute brightness of celestial objects. The absolute magnitude of an object is defined as the apparent magnitude it would have if it were viewed at a standard distance of 10 parsecs (32.6 light-years) with no dimming of its light. The more luminous an object, the smaller the numerical value of its absolute magnitude.</span></span>
