Refer to the figure showing a pedigree of a family affected by an x-linked recessive disorder. a female in generation 3 isn't a carrier of the disorder. how can this be? a. females receive an x chromosome from each parent. if a mother is a carrier of an x-linked recessive disorder, her daughters have a 50 percent chance of receiving her normal x chromosome and a 50 percent chance of receiving her mutated x chromosome. b. females receive x chromosomes from their fathers only, which are unaffected in this case. c. females don't have x chromosomes so aren't affected by gene disorders passed on the x chromosome. d. females receive an x chromosome from each parent, but in cases of recessive disorders, the mutated chromosome isn't passed on to daughters.

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.

i hope this : )

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.
