In ovulation, after expelling the oocyte the follicle becomes ____________which produces_____________.
corpus luteum; FSH and LH
corpus albicans; progesterone
corpus albicans; estrogen and progesterone
corpus luteum; estrogen and progesterone
The Correct Answer is D
A. Corpus luteum; FSH and LH: The follicle transforms into the corpus luteum after ovulation, which secretes hormones. However, FSH and LH are hormones secreted by the pituitary gland, not products of the corpus luteum.
B. Corpus albicans; progesterone: The corpus albicans is a degenerated form of the corpus luteum and is not responsible for secreting progesterone.
C. Corpus albicans; estrogen and progesterone: The corpus albicans forms after the corpus luteum degenerates and does not produce significant levels of estrogen and progesterone.
D. Corpus luteum; estrogen and progesterone: After ovulation, the follicle transforms into the corpus luteum, which secretes estrogen and progesterone to support the early stages of pregnancy or regulate the menstrual cycle if pregnancy does not occur.

Correct Answer is B
Explanation
A. Renal filtrate refers to the fluid filtered from the blood in the glomerulus, which is the initial stage of urine formation. It does not immediately precede urine.
B. Tubular fluid is the filtrate as it passes through the nephron tubules, undergoing various processes like reabsorption and secretion. This fluid eventually becomes urine, after the final adjustments in the collecting duct.
C. Plasma is the liquid component of blood that is filtered by the glomerulus, but it is not the direct precursor to urine.
D. Glomerular filtrate is the fluid filtered out of the blood in the glomerulus and is the precursor to tubular fluid, not directly to urine.
Correct Answer is A
Explanation
A. Y chromosome: The SRY gene on the Y chromosome codes for the testis-determining factor (TDF), which initiates the development of testes and male characteristics.
B. Gonadal ridges: The gonadal ridges are the precursor structures that develop into gonads but do not contain the gene for TDF.
C. X chromosome: The X chromosome contains genes important for development but does not code for TDF.
D. Fetal testes: The fetal testes produce testosterone but are not the source of the TDF gene.
