Identify which statements are correct. A. All bacteria have peptidoglycan in their cell walls. B. All fungi have chitin in their cell walls. C. All algae have cellulose in their cell walls D. All protozoans have protein in their cell walls.

A. All bacteria have peptidoglycan in their cell walls. B. All fungi have chitin in their cell walls. C. All algae have cellulose in their cell walls

Explanation:

The cell wall of a bacteria has peptidoglycan. Peptidoglycan is the basic unit of the bacteria cell wall, it makes the cell wall strong, and determines the cell form.

The cell wall of a fungi contain chitin. Chitin makes the cell wall strong, and rigid.

The cell wall of an algae has cellulose. The cellulose helps to provide rigidity and in maintaining the shape of the cell walls of the algae.

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.
