I believe temperature is the answer
Answer:
II. Pulmonary edema occurs when interstitial fluid accumulates in tissues of the lung
Explanation:
Pulmonary edema is a condition that occurs when excess of fluid filled in the numerous air sacs in the lungs, making it difficult to breathe.
Symptoms of pulmonary edema include wheezing, extreme shortness of breath, Cold, clammy skin, feeling of suffocating or drowning , Anxiety, and restlessness or a sense of apprehension.
Treatment for pulmonary edema depends on the cause and generally include supplemental oxygen and medications.
Hence, the correct option is II. Pulmonary edema occurs when interstitial fluid accumulates in tissues of the lung.
The correct answer is option (d) They allow the exchange of gases between cells in the leaf and the external environment.
Stomata are the tiny openings present in the epidermis (outer layer of cells) of the leaf. They have a pore which is guarded by the guard cells which controls the opening and closing of the stomata. Air enters and exits through the stomata.
The main funtion of stomata is to facilitate the gaseous exchange. The gas exchange that occurs when the stomata are open helps in the process of photosynthesis. During photosynthesis, carbon dioxide is taken in from the atmosphere and oxygen is released as a by-product of photosynthesis. The glucose produced is converted into the starch and stored in the leaves.
Also, water vapour diffuses through the stomata into the atmosphere by a process called the transpiration.
Thus, stomata are the structures that are mainly involved in the gaseous exchange between the cells of the leaf and the atmosphere.
