Lysosomes remove waste at a cellular level.
They contain digestive enzymes, so they're like the digestive system.
The stomach digests food, so lysosomes could be considered like the stomach.
But then again, so do the intestines, small and large.
Since the stomach doesn't also work to remove waste though, I'd say the answer is probably large intestine, which finishes the digestive process and removes waste material.
The prokaryotes are unicellular organisms that lack organelles or other internal membrane-bound structures. Therefore, they do not have a nucleus, but, instead, generally have a single chromosome: a piece of circular, double-stranded DNA located in an area of the cell called a nucleoid
Because it’s time consuming and money consuming to observe from space so models are required
The answer is logistic growth.
It is modeled by an S-shaped curve. Carrying capacity (K) is the maximum individuals of a population that a habitat can sustain indefinitely
given the limited resources in the environment. Before this number
is achieved, the population grows exponentially and slows as it gets close. When
the K number is reached, the stationary phase enters.
