Will give brainliest 4. are the base pairs always the same? 5. if there were five guanine bases in one strand of your model of dna, how many cytosine bases would there be in the complementary strand? 6. if there were 10 bases of thymine in one strand of your model of dna, how many adenine bases would there be in the complementary strand? 7. if the dna molecule is so similar among all living things (the pairings are always the same and that there are only six components that make up dna), why is there so much diversity of life?

metamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks (protoliths), without the protolith melting into liquid magma (a solid-state change). the change occurs primarily due to heat, pressure, and the introduction of chemically active fluids. i hoped i !

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 : )
