- Although rabbits cannot digest the cellulose in their all-plant diet, bacteria that live in their cecum can. However, to make full use of the nutrients released by bacterial action, a rabbit must produce and eat a special type of feces. Why must the rabbit reswallow this material to obtain the nutrients released by bacterial action?Some people who have gallstones experience pain after they eat, with fatty meals causing the greatest discomfort. Why do such meals trigger gallbladder pain? Diabetes insipidus is a medical disorder in which a person produces an unusually large amount of highly dilute urine. Some cases are caused by a gene mutation, but in most people, diabetes insipidus arises after a head injury. Explain how an injury to the head could affect kidney function.Marine mammals and desert rodents both have highly efficient kidneys that produce only a tiny amount of very concentrated urine. What selective pressure shaped this trait in both animals?ATP for muscle contraction can be provided by ______. a. aerobic respiration b. lactate fermentation c. transfer of a phosphate from creatine phosphate d. all of the aboveIt is being said that our bodies cannot produce lactic acid but rather lactate and it's the metabolite summation of ATP, hydrogen, and lactate that cause the burn. But I was taught that lactic acid does not cause muscle burning sensation but instead its the increase in proton concentration that creates an acidic environment but since lactate is the component measured in the blood and blood is strictly a weak base and lactic acid is the corresponding acid and uses muscles as an energy it can help reduce the acidity. So I'm just confused and would like some clarification if our bodies do have lactic acid and what causes the burning sensation in our muscles when getting a pump
