Fleas are wingless insects that undergo complete metamorphosis with four stages: egg, larva, pupa, and adult. fleas prefer a warm, humid environment, with temperatures ranging between 70° and 90° fahrenheit and a relative humidity of 75% or more. under ideal conditions, the cat flea life cycle takes just 18 days, from egg to adult. fleas require a blood meal on a regular basis. they prefer blood from your pet, but they will also fleas will bite you! bites are common around a person’s ankles or on their feet. the bites itch! the female flea may deposit up to 50 eggs per day on your dog or cat. as your pet walks around your home, many of the flea eggs fall off. flea eggs are tiny so they can go unnoticed in your pet's bedding, in carpets, or on upholstered furniture
according to the passage, the flea is a and your pet dog is the

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
