The maternal effect Drosophila mutation bicoid (bcd -
) is recessive. A
female that is bcd
-
/bcd
+
is mated to a bcd
-
/bcd
- male. What is the outcome?
A) 50% of the eggs will hatch, and these will produce fertile adults
B) no eggs will hatch
C) all eggs hatch, but 50% of the resulting daughters produce eggs
that fail to hatch
D) it is impossible to get a bcd
-
/bcd
- male, so this mating can not
occur
E) 50% of eggs will hatch, but half the female offspring will be infertile

I need the points :

the supermassive black hole is in the middle of the galaxy.

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.
