The equations summarize the process of fertilization. which equation represents fertilization? haploid + diploid = diploid diploid + haploid = haploid haploid + haploid = diploid diploid + diploid = diploid it's urgent

haploid + haploid = diploid

Fertilization is a process in sexual reproduction in which the male gamete fuses with the female gamete in order to produce the zygote which is the precursor of new organism. The ploidy of the male gamete cell is haploid (n) also that of the female gamete cell is haploid (n), when these two gamete cells fuse together they form a diploid zygote (n) cell. Hence, haploid + haploid = diploid is the correct equation.

relative humidity, temperature and dew point -- are bound together in the mathematical relationship below. relative humidity changes when temperatures change. because warm air can hold more water vapor than cool air, relative humidity falls when the temperature rises if no moisture is added to the air. so i would say a

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.
