How does a dog meets all of the characteristics of life.?

The main 7 characteristic of life is movement, respiration, sensitivity, growth, reproduction, excretion, and nutrition.

The dog can use their legs and walk to a place to another, this meets the "movement".

The dog can breathe and undergo gas exchange therefore "respiration" is met.

The dog can detect changes from the environment and respond to them, such as they figured out the weather becomes cooler so they would find a warm blanket or spot to rest in, so "sensitivity" is met.

The dog would grow bigger in size throughout time, so "growth" is met.

The dog would find a mate and reproduce to pass on their genes, so "reproduction" is met.

They would excrete waste from their body, they have the ability to get rid of the excess material out from their body, so they can meet the "excretion" characteristic.

Last but not least, a dog need to eat food in order to get energy, so "nutrition" is also met.

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".
