Which domains contain organisms that only conduct asexual reproduction

Two domains: Archaea and Bacteria

Explanation:

There are three domains of life namely Archaea, Bacteria, and Eukarya. Both Archaea and Bacteria contains organisms that reproduce asexually, i.e. binary or multiple fission, fragmentation, or budding. By these means, organisms divides its cells to more than one cells containing splited genetic materia. The dividing cells then can survive independently.

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.
