Potassium is a mineral which appears in abundance in all living plant and animal cells. The human body uses it to promote regula
r heartbeat, help build muscles, help contract muscles, regulate blood pressure, and control the water balance in body tissues and cells. Calcium is a mineral that primarily functions in your body by making your bones and teeth hard. The rest is in your blood and soft tissues; it helps your muscles contract and your blood clot, and helps your nervous system work properly. According to your knowledge of atomic structure, explain why the calcium atom is smaller than potassium atom.
Calcium also shares the same fourth period in the periodic table in which potassium present. The size of the atomic radius decreases from left to right in the period from left to right. Potassium present left to the calcium in the fourth period.
The reason for the decrease in the atomic radius due to the fact though electrons and protons increases but the valence shell remains the same from moving from left to right, therefore, as the net charge increases with the increase in the electrons result in shrinking of the valence shell and resulting in the decrease of the size of the atom.
because an independent variable is something you change. So in a scientific experiment you only change one thing. If you happen to change more than one thing then the test becomes unfair therefore you should repeat and make sure that only one thing is changed this time.
Lipase is a type of enzyme known as a hydrolase and is responsible for catalysing the hydrolysis of triglycerides (the substrate) into fatty acids and glycerol
The barnacles are only able to attach them selfs to surfaces in the water. Since the surface is limited, barnacles are attaching themselves to the other barnacles, crowding the rock. The muscles were not able to grow or attach themselves off the surface of the rock. Same thing with the mussels that are growing on the rock. So not only barnacles are crowding the rock, but Mussels as well are crowding the rock.
The correction option is VENTILATE THE AREA. In order to reduce indoor air pollution, the best thing to do is to ventilate the area. Ventilation involves provision of fresh air into a room in order to flush out and eliminate indoor pollution.
