how does mitosis and meiosis benefit various organisms’ survival?

Meiosis allows reproduction to happen and mitosis allows the growth and development of the organism. All of this contributes to the survival of the individual and the species.

Explanation:

The importance of mitosis is that it provides the growth and development of our body, and also acts by replacing lost cells. Meiosis, on the other hand, is fundamental for the maintenance of the life of multicellular beings, because it is through it that the reproduction cells are formed.

Moreover, mitosis is important because it generates daughter cells identical to the mother cell, acting on vegetative processes such as regeneration, hypertrophy. Meiosis is already responsible for the genetic variability of the offspring, and is therefore more evolutionarily adaptive, and, therefore, used in the gametogenesis of many species (Not all, as is the case with plants, very important multicellular beings that form the gametes by mitosis, although they form the spores by meiosis.).

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.
