The study of living organisms, divided into many specialized fields that cover their morphology, physiology, anatomy, behavior, origin, and distribution.
Answer:
Weakening of digestive smooth muscle with age can cause constipation.
Explanation:
Smooth muscles in the digestive system have the role to move food down the tract via radially symmetrical contractions (peristalsis). With age, the function of smooth muscles reduces, causing the food to move more slowly through the alimentary canal (digestive tract). As a consequence, water gets absorbed from food waste, which can cause constipation.
There are lots of animals that do this and they are classified as herbivores.
cellular respiration releases the greatest amount of energy or ATP.
Explanation:
In cellular respiration 38 ATPs in the process. 4 molecules of ATP are formed in glycolysis, 32 molecules in Oxidative phosphorylation.
alcoholic fermentation: 2 ATP is formed
lactic acid cycle: 2 ATP is formed
photosynthesis: does not produce ATP instead ATP formed from the glucose formed is used in the process.
