The diagram below shows the positions of earth, sun, and moon during two types of tides.

both represent tides during which (2 points)

a. the difference between the high and low tide is the greatest
b. the difference between the high and low tide is almost equal to the high tide
c. the gravitational forces due to the sun and the moon cancel each other's effect
d. the gravitational forces due to the sun and the moon amplify each other's effect

The correct answer is C: the gravitational forces due to the sun and the moon cancel each other's effect.

c. the gravitational forces due to the sun and the moon cancel each other's effect

Explanation:

The two diagrams represent Neap tides. Neap tides occur when the Sun, the Moon and the Earth are aligned at right angles. Moderate tides are formed because the bulge due to gravitational pull of the Sun cancels the bulge due to moon. The difference between the high tides and the low tides is the smallest.

true, i don't really know what you're asking but from the info you provided im guessing the answer is true.

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.
