Answer:
The two important conditions that must be met before gram staining are-
1. The age of the culture should not exceed 24 hours.
2. Over heating, decolonization should be avoided.
Explanation:
Gram staining is a technique developed to distinguish the bacteria on the basis of the composition of the cell wall around the bacteria.
The gram stain is a sensitive technique so must be performed carefully. The precautions should be taken to avoid any error while gram staining that is-
1. Age of the culture- The culture should be freshly prepared just 18-24 hours before the experiment as above 24 hours bacteria lose their ability to retain the color so one would not be able to differentiate between the cultures.
2. While performing the experiment one should avoid overheating and decolorization with ethanol as both the factors lead to the loss of crystal violet stain from the cell and they take pinkish color after safranin staying.
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.

Explanation:
La siguiente entrada tiene como objetivo realizar una breve explicación sobre las moléculas biológicas lipídos y carbohidratos, las cuales son muy diversas ya que están formadas por carbono, lo cual hace que puedan formar muchos tipos de enlaces. Esta capacidad permite que las moléculas orgánicas adopten muchas formas complejas, como son las cadenas, las ramificaciones y los anillos.
Las moléculas biológicas son grandes polímeros que sintetizas para poder enlazarse con otras subunidades mucho mas pequeñas conocidos como monómeros. Las cadenas de subunidades estan unidas por enlaces covalentes los cuales se forman por deshidratación, estas cadenas pueden romperse por hidrólisis. La moléculas biologicas más importantes son los carbohidratos, lípidos, proteínas y ácidos nucleicos.
Answer:
I believe your answer would be --
B.) They remove urine from the body.
After the Big Bang happened, the universe is constantly expanding. The Universe has expanded for around 13.7 billion years. The further a galaxy is, the faster it would move away from Earth. This principle is called the conservation of momentum.
