What is the role of proteins in a chromosome ?

The role of protein in the chromosome is to condense and coil DNA.

Explanation:

Proteins in a chromosome are to assist condense the DNA. Cells have very large DNA in each nucleus however cells are microscopic. This is where protein which is histone proteins play their role.

DNA is being wrapped or coiled around these small proteins termed histones. Eight histone proteins combine to forms bead called a nucleosome that DNA coil around.

Thus, the correct answer is its helps in condense and coil DNA.

i was told this before by a teacher, so yeah

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.
