[Type text] [Type text] [Type text] _An experiment on the effect of surface area to volume ratio on the rate of osmosis of Solanum tuberosum L._ BACKGROUND A cell needs to perform diffusion in order to survive. Substances‚ including water‚ ions‚ and molecules that are required for cellular activities‚ can enter and leave cells by a passive process such as diffusion. Diffusion is random movement of molecules in a net direction from a region of higher concentration to a region of lower concentration

AIM: To carry out a lab experiment to decompose a carbonate using heat‚ also to carry out appropriate tests for the formation of products as a result of this decomposition. DISSCUSION: Carbonates are decomposed by heat into the corresponding oxides and carbon dioxide. The temperature of decomposition depends upon the activity of the metal; that is to say‚ the more active the metal‚ the more stable is the carbonate. Thus‚ the carbonates of sodium and potassium are stable at the highest temperature

Homeostasis – Re: Calcium Homeostasis refers to a stable internal balance or an internal equilibrium within the human body. The body and its systems work together to keep itself in the state of balance‚ but it mostly refers to how the human body reacts to different changes and keep itself within certain guidelines to insure that it can properly function. These reactions include a range of responses‚ from the release of hormones to regulate internal balances to sweating to lower body temperature

Calcium Carbide Calcium Carbide is a chemical compound containing calcium and carbide‚ with a chemical formula of CaC2. Pure Calcium Carbide is colorless‚ but some are black or grayish-white color‚ depending on the quality. Calcium Carbide is mostly used for the production of the flammable gas acetylene‚ which is similar to the natural hormone created my plants Ethylene. Ethylene is a hormone that is used by plants to ripen fruits. In Bangladesh and some parts of South-East Asia‚ Calcium Carbide
