Which of the following statements is true about a gut that scales to the 3/4 pow

Question

Which of the following statements is true about a gut that scales to the 3/4 power of body mass? The guts of larger animals are proportionately smaller than the guts of smaller animals. The guts of larger animals are proportionately larger than the guts of smaller animals. The guts of larger animals are proportionately the same size as guts of smaller animals. The guts of larger animals are absolutely and proportionately larger than the guts of small animals. Diets high in fiber are expected to have which of the following: Higher rates of digestion. Lower retention times. Lower energy efficiency. Higher carbohydrate content. When digestive capacity increases which of the following is a concern The change in digestive system will result in decreases in immune function. The long term digestive capacity will be decreased as immediate spare capacity increases. The energetic costs of increased organ sizes outweigh the benefits on increased digestive capacity. Increase

Explanation / Answer

Answers: 1. the intestine and digestive system varies among the animals but this has been seen that smaller animals have larger guts comparing their body type and comparing the proportions of that to larger animals.
The correct option here is option 1.
2. Fibers are the plant materials, edible parts of them or similar carbohydrates, only problem with the digestion is that fibers are not easily digested and absorbed in the small intestine.
They are the second type of carbohydrates which are not easily digestible, for example- cellulose, pectin, starch etc. Here our right answer choice will be 4th option- Higher carbohydrate content.
3. Digestive and immune system work hand-in-hand. Most of the immune cells are around our digestive system, almost 80% of them. They are interdependent, if the bacterial colony inside our intestine and other digestive tracks lowers or disturbs immune system becomes active. Basically if digestive system works more even immune system will also be active.
Even ultimate spare capacity increases in feeding rate. The spare capcacity increases if the digestive system would pick up less of digestive load. So the proportion decreases with spare capacity is digestion increases. Here our right answer choice is option 2.
Increased digestive capacity would lead to ingest and digest food more for the requirement of more energy. That could also be associated with lot of energy to produce. So there is not straight relation between the digestion rate increase and obesity.
Finally we have the 3rd option- The energetic cost of increased organ sizes outweighs the benefits on increased digestive capacity. This is also not wholly true.
4. Birds and mammals are having holozoic nutrition and surprisingly they both have very common type of digestive system. They even share the body weight to food intake ratio, thus it has seen that similar size of them would consume the same amount of food. The first option suggesting the amount of food, which is correct in the first place.
Glucose and amino acid intake varies among them, the birds. For mammals we have different requirements. Here this option is not viable.
Bird’s esophagus is large and big comparing ours and they have their digestive system organ like intestine and duodenum same like ours, only an extra organ is there like our stomach they have gizzard.
The small intestine of birds is very much similar to mammals. Also they have similar enzymes too, so choosing here the option would seems to be good, the option 3, but that’s not a correct choice.

5. Bones might look like non-changing and stable but inside our body there is a constant functional change in their model. Bones have two types of cells the osteoclasts, these are the bone-reabsorbing cells and osteoblasts are the bone forming cells.
SO bone remodeling is constant and structural process thus the option is TRUE.
