a) Accumulation of which acid in the body causes muscular cramps ? b) Which muscular part of the body present in the chest cavity helps air to be breathed in and out ? c) What do you mean by ''stomatal apparatus''? d) In yeast,glucose is broken down into which two components after anaerobic respiration.e) How does exchange of gases occurs in the cockroach.
Answers
Answer:
Explanation:
a. Traditionally, such cramping was believed to arise from dehydration, electrolyte imbalances (including magnesium, potassium and sodium), accumulation of lactic acid, or low cellular energy levels.
b. diaphragm
c. Stomatal apparatus is a pair of guard cells with or without surrounding subsidiary cells which function as a value to open or close a stomatal pore for gaseous exchange and transpiration. Each stoma is made of two bean-shaped cells called the guard cells.
d. Alcoholic fermentation is the process of converting glucose into the molecule ethanol. This process is generally done by microscopic organisms like bacteria and certain fungi like yeast. The glucose are broken down by glycolysis releasing two ATP molecules and creating two pyruvic acid molecules.
e. When oxygen-rich air enters into the body of the cockroach via spiracles into the tracheal tubes, it diffuses into various tissues and cells of the body. Here, oxygen is used up to liberate energy. Likewise, carbon-dioxide rich air passes into the trachea and moves to the outwards through the spiracles.
