In case of CMCase‚out of the supplemented sugars‚glucose‚sucrose‚maltose‚lactose‚wheatbran and CMC‚ wheat bran show maximum increase in enzyme production. On addition of glucose‚ maltose‚ lactose‚wheat bran and xylan‚ the maltose resulted in an increment in xylanase production (24.96 IU/ml) by SmF. An induction in the enzyme production/activity

causing more of the air to dissolve in the bloodstream of that person. The main components of air are oxygen‚ which is continuously used by the body‚ and nitrogen‚ which isn’t used by the body‚ so when a diver ascends or rises too quickly to the surface‚ the pressure decreases and the blood can no longer hold all that nitrogen dissolved in it. The nitrogen forms bubbles in the blood and enter into the joints‚ such as the elbows and knees‚ and causes pain in those areas. In worst cases‚ extreme pain can

Over the past century‚ as a side effect of food production‚ humans have been releasing huge amounts of nutrients‚ specifically nitrogen and phosphorus into water resources like lakes‚ rivers and even oceanic coasts. This has caused enormous growth in algae populations‚ literally choking the life out of aquatic ecosystems and polluting water for humans as well. These “Harmful Algal Blooms” (HAB’s) or green tides as some call them can produce toxins that can hurt animals and humans alike turn water

between lithium (metal) and nitrogen (nonmetal)‚ you first look at how many lithium valence electrons there are. You can determine this by looking at lithium’s charge which is +. + means that there is only one. For nitrogen‚ you look at the group that nitrogen is. Nitrogen is in Group 15‚ so it has 5 valence electrons. So how many of each atom can make the entire compound neutral? You need THREE lithium atoms so that they each give away one valence electron to nitrogen. This way‚ all the atoms are

around us. The Earth’s atmosphere is mainly composed of about 78% oxygen and 21% nitrogen. The oxygen and nitrogen present in the atmosphere are both in the form of ‘’diatomic molecules’’‚ as shown below: The subscript 2 of oxygen and nitrogen indicate the number of oxygen atoms and nitrogen atoms. So the oxygen molecules present in the atmosphere have two oxygen atoms and the nitrogen molecules have two nitrogen atoms.
