Answer:
The correct answer is - stomata, transpiration.
Explanation:
Photosynthesis is the process that uses light to convert CO2 and water to produce sugar and oxygen. The carbon dioxide is taken up by the little holes-like structures present on the spongy layer of the leaves called stomata. These structures are used for gaseous exchange, taken up oxygen, and releasing oxygen.
Stomata also help in releasing water vapors from the aerial parts during the process of transpiration to prevent the plants to burn in a dry environment and wind.
Answer: 21%
Explanation:
The atmosphere is the gaseous portion of the planet Earth. It therefore consists of several gases and air particles.
In the atmosphere,
-Nitrogen is the most abundant gas with 78%
- Oxygen takes 21%,
- Carbon dioxide takes 0.03%,
- the remainder is unreactive gases and particles.

Hypothalamus. A bridge between the nervous system and the endocrine system, which regulates hormones in the body, the hypothalamus also controls body temperature and is responsible for sensations of hunger and thirst.
