Ryan is looking at a cell under the microscope. he observes formation of spindle microtubules from the centrosomes. which phase of the cell cycle is he observing? a metaphase, b anaphase and c prophase

hope it mark me as brainlieast.

the level of progesterone is low at the pre-ovulatory phase of the cycle but it gradually increases and the levels are high at the luteal phase. if pregnancy occurs, the level of progesterone will be high throughout the pregnancy.

if egg is fertilized and the mother gets pregnant, progesterone starts preparing the uterus for the implantation. it starts building up the lining of uterus and make it hostile of the period of pregnancy.
