What was rudolph virchow’s contribution to the cell theory?

he concluded that all cells come from preexisting cells.

he concluded that cells are the basic units of structure and function of all living things.

he concluded that all organisms are composed of cells.

he concluded that all cells are similar in composition and metabolic activities.

He concluded that all cells come from preexisting cells.

Explanation:

The cell theory is made up of the contributions of three important scientists :

1. Rudolf Virchow

2. Theodor Schwann

3.  Matthias Schleiden

The cell theory comprises of three important aspects ;

1. The cells are the units that makeup all the living organisms.

2. Cells are the basic functional and structural unit of all the living beings.

3. New cells are formed from the division of old cells (pre-existing cells).

Amongst these three aspects of the cell theory, the third one is contributed by Rudolf Virchow.

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat.   although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.
