Which would likely live in a bog, a sewage treatment plant, or a cow’s intestine? a) methanogen b) halopile c) thermoacidophile d) eubacteria

A). Methanogen  

Methanogens are anaerobic unicellular microorganisms. They belong to the domain archea. They are found in anerobic environments like swamps, bogs, sewage sludge, marshes and also in the rumen part of the intestines of the cattle. They use hydrogen, carbon dioxide, acetate, formate and methanol to produce methane and heat as a result of anaerobic fermentation. Their main function is the removal of excess of hydrogen and the fermentation products. The release of the methane to the atmosphere contributes to the carbon cycle.

characterization of nanoparticles is a critical step in nanomaterial production as it provides information of dimension, morphology, surface charge, distribution and degree of surface functionalization.

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.
