City-state government was often conquered because they did not have enough resources to protect themselves
Explanation:
A city-state government is an independent autonomic political system which usually compromises just a single independent city which is governed by itself with sovereignty over its territory. The city-states like Greece, Italy, and Rome etc became very powerful.
The main reason for these city-states being conquered more was the accumulation of wealth and aristocracy in such states.
Heavy taxes, religion, slavery also lead to social unrest and conflicts among these city-states which made them weaker. These internal conflicts also made them lose their resources and vulnerable to be conquered by other powerful empires.
With the increasing power of neighboring states, like in the case of Rome and Greece, the Romans became mightier than Greeks at one point and conquered the Greek city-states.
Answer: It has multiple nuclei, It is one of the smallest of cells with among the smallest of genomes.
Explanation:
Mycoplasma mycoides is a bacterial strain of the genus Mycoplasma. It belongs to the class of Mollicutes. This is parasitic in nature. It lives in the ruminants. It is smallest known bacteria that does not posses the cell wall. It is present everywhere as a pathogen. It's function is to interfere with the ability of the virus to affect the mammalian cells. It posses multiple nuclei.
It is smallest free-living single celled organism. Due to the small size the entire genome can be sequenced. It can be useful for purpose of research and it is of particular interest because of it's small cell size and multiple nuclei. It serves as a model organism to study the bacterial evolution.
B. An ecosystem in which plant roots are submerged during parts of the years
Answer:
fern is the producer.
Explanation:
producers are mainly green plants.
One of the major elements of natural selection is that all species have genetic variation. Natural selection is a process when organisms adapt better to their environment. It is an essential key in evolution. There is a change in phenotype of a population over time.
