Which of the following describe density-dependent factors? They act to regulate population growth. They can affect birth rates or death rates. One example would be intraspecific competition for resources. They are especially important in K-selected populations. They do not involve biological interactions. They can affect growth rates but not population size.

Correct options are

a) They act to regulate population growth.

b) They can affect birth rates or death rates

c) One example would be intraspecific competition for resources.

Explanation:

Population growth rates can be regulated by the density of a population and hence population regulation is a density-dependent process.  Density-dependent factors include disease, competition, and predation.  

The higher the population density, the higher is the mortality rate.  

Some of the biotic density dependent factors are  

a)intra- and interspecific competition

b)reducing population’s rate of growth

c)Individual’s reproductive rate

Hence, the correct options are

So the correct options are

a) They act to regulate population growth.

b) They can affect birth rates or death rates

c) One example would be intraspecific competition for resources.

they both go up but then go back down. they both end lower than they started. lastly, they both are competitive/the second on.

explanation:

interphase

the period of cell growth when the cell synthesizes new molecules and organelles. the cell is not dividing and it constitutes the majority of the time spent in the cell cycle

prophase

changes occur in the nucleus and cytoplasm. the chromatin condenses to form structures (sister chromatids) visible with a light microscope and the mitotic spindle begins to form, but the nucleus is still in tact

prometaphase

the nuclear envelope fragments and the spindle microtubules attach to the kinetochores of the sister chromatids

metaphase

all the cell's duplicated chromosomes are lined up at an imaginary plane equidistant between the poles of the mitotic spindle

anaphase

begins when sister chromatids separate from each other and ending when a complete set of daughter chromosomes arrives at each of the two poles of the cell

telophase

the daughter nuclei form at the two poles of a cell

cytokinesis

the division of a cytoplasm to form two separate daughter cells. usually occurs during telophase during mitosis. this and mitosis make up to mitotic (m) phase of the cell cycle
