Describe how fertility drugs help women to become pregnant​
Sophie [7]

Answer:

Fertility drugs contain FSH and LH, which stimulate eggs to mature in the ovary. Fertility treatments increase a woman's chance of becoming pregnant, although the treatment may not always work.

A.they ruled much of West Africa

B.they built large cities in the West African rain forest

C. they controlled the gold for salt exchange

D. they grew powerful through trade

Answer:

B. They built large cities in the West African rain forest.

Explanation:

"They built large cities in the West African rain forest" doesn't describe all three kingdoms of Ghana, Mali, and Songhai.  Ghana, Mali, and Songhai were three of the greatest western African trading states. They controlled the trade of gold, salt, and merchandise between North Africa and sub-Saharan Africa in the 16th century. Their strong trade grew them powerful.

Which study led biologists to infer that the ancient archosaur was active during the night? ancestral state reconstruction sugge
MrRissso [65]
The correct option is this: ANCESTRAL STATE RECONSTRUCTION SUGGESTING THAT THESE ANIMALS HAD OPSINS THAT WERE SHIFTED TOWARD THE RED.
Ancestral reconstruction is the extrapolation back in time from measured characteristics of individuals to their common ancestors. Opsins are a group of light sensitive proteins that are located in the photoreceptor cells of the retina of the eyes. Having opsin that were shifted toward the red colour will enable the animal to see very well in the night time, thus, the animal will be active during that period.
