2.a) yes
b)no
Answer:
Explanation:
1.Frogs, like salamanders, newts and toads, are amphibians. Most amphibians begin their life cycles as water-dwelling animals, complete with gills for breathing underwater. As they grow to adulthood, amphibians normally become land-dwelling creatures, lose their gills and develop lungs for breathing. Frogs have lungs like we do and if their lungs fill with water, they can drown just like us. Frogs can also breathe through their skin. ... They use their skin to absorb oxygen when underwater, but if there is not enough oxygen in the water, they will drown.
2. During anaerobic respiration in plants (like yeast), ethanol, carbon dioxide and energy are the final products.(a)There is a build-up of lactic acid in the muscles during vigorous exercise. The lactic acid needs to be oxidised to carbon dioxide and water later.(b)The resultant products of anaerobic respiration if occurs in plants especially like yeasts are along with little amount of energy ethanol and carbon dioxide are released. So the yeast cells are widely used for fermentation process.
