What hormonal change occurs after fertilization that causes the endometrial lining to remain intact so that the fertilized egg can successfully implant in it? A.
The pituitary gland secretes oxytocin, which maintains the endometrial lining.
B.
The pituitary gland secretes follicle stimulating hormone, which acts on the follicles and stimulates them to produce progesterone.
C.
The hypothalamus secretes gonadotropin releasing hormone, which maintains the endometrial lining.
D.
The developing embryo secretes human chorionic gonadotropin, which prevents the corpus luteum from disintegrating.
E.
The developing embryo takes over the production of progesterone after the breakdown of the corpus luteum to maintain the endometrial lining.

Ry was studying two populations of the same species of lizards. one population lived on an island and the other lived on the mainland. both populations were affected by a hurricane that hit the island and the mainland with equal force. a year later, henry was testing the gene frequency and saw a decrease in genetic variation in the island species, but not in the mainland species. which best describes a conclusion he might have reached? gene flow greatly affects small populations, but large populations can recover. genetic drift greatly affects small populations, but large populations can recover. gene flow greatly affects large populations, but small populations can recover. genetic drift greatly affects large populations, but small populations can recover.

Agenetically engineered corn plant is approved for agricultural use. the plant produces pollen that can make its own toxins. these toxins protect the corn plant against pests and no longer require the application of chemical pesticide. what is a likely impact on the farmer of growing such a variety of corn? a- the financial costs for the farmer would be lowered since less crops would be lost to pests. b-the financial costs for the farmer would be lowered since more crops would be lost to pests. c-the farmer may be held responsible for increasing chemical pollution. d-the farmer's expenses for pest control would increase due to an increase in bee population.
