Ozone molecules are good for the earth because they absorb

There are no options in this question, however, the answer is:

Ultraviolet radiation

Explanation:

Ozone is a molecule composed of three oxygen atoms (O3). Ozone, forms a layer called OZONE LAYER in the part of the Earth's atmosphere called STRATOSPHERE. This ozone is formed when an oxygen atom (broken from a molecule by UV light) combines with an oxygen molecule.

The ozone layer in the stratosphere helps to prevent the detrimental ultraviolet radiation from the SUN from reaching the Earth. The ozone molecule does this by absorbing the UV radiation before it reaches the Earth. Hence, ozone molecules are good for the earth because they absorb ultraviolet (UV) radiation.

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.
