Coprophagy is important for the nutritional balance of _________.
prohojiy [21]

Coprophagy is important for the nutritional balance of rabbits and their relatives.

The behaviors of the rabbit, rat, mouse, hamster, guinea pig and chinchilla have all been linked to coprophagy, which is the act of an animal re-consuming its own discharged excrement. Cecotrophy is a better name for it.

The omnivorous rats, mice, and hamster display cecotrophy to a lesser level than herbivores' hindgut fermenters like the rabbit, guinea pig, and chinchilla. In order to boost the supply of folic acid and vitamin B12, it may rise during pregnancy and lactation.

Coprophagy is an intrinsic behavior triggered by the reflex, despite the fact that modern diets make it unnecessary for survival.

1. Why is Earth an example of a system?
AURORKA [14]

Answer:

The earth can be said to be a system because each component inside it interacts so that it creates a very large number of collectivities. Components in the earth are incorporated into a Geosphere, namely a layer on the surface or under the surface of the earth that has a direct and indirect influence on the survival of creatures

A student performed an experiment with bags of dialysis tubing filled with distilled water to model the process of osmosis. Dial
Reil [10]

Answer:

Taking into account the principle of osmosis, the question that best addresses experimental design is  <em>How does the effect of environmental sucrose concentrations impact the  movement of water across a membrane?</em>

Explanation:

The experimental design of the student, made with dialysis bags and sucrose at different concentrations should recreate the principle of osmosis, of importance in living beings for organic homeostasis.

Osmosis consists of the movement of water - through a semi-permeable membrane - from a less concentrated solution to a higher concentration solution, following a gradient, to achieve balance.  

The student will observe in his experiment that water moves from the solution with less sucrose concentration to the higher concentration of sugar. Beakers with the highest concentration of sucrose will have the highest weight, due to the increase in liquid volume.

How does the effect of environmental sucrose concentrations impact the  movement of water across a membrane?

The experiment shows that:

  1. The water from the beaker with less sucrose concentration moved -through the dialysis tubes and the membrane- to the beaker containing the most concentrated sucrose.
  2. Different sucrose concentrations will attract different amounts of water, which influences the final weight of each container.

With this experiment the principle of osmosis is confirmed, where the concentration of a solute determines the amount of water that passes through a semipermeable membrane -following a concentration gradient- until equilibrium is reached.
