Which factor is a density-dependent limiting factor on the population of a species?

Competition

Explanation:

In biology, density-dependent limiting factors directly affect the growth of a population, which normally cause a decrease in the number of individuals in an ecosystem.

There are different density-dependent limiting factors, and one of them is competition. Animals, either from the same species or different species, are always competing for resources, such as food (prey). This factor intensifies along with the increase of the population, that is, the more individuals are in a given area, the availability of prey will decrease and the competition will increase.

the unequal cytoplasmic division that  results  in  one egg  and three polar bodies ensures that a fertilized  egg has  ample nutrients  forits journey  to  the uterus.

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere   and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust.   the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles.   three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.
