matter and energy cycle throughout systems. The cycling throughout networks can be explained by the Law of Conservation of Matter and Energy‚ which states that matter and energy cannot be created or destroyed‚ only changed. This cycle applies to many things‚ such as energy cycling through a food web‚ carbon traveling through the biosphere in the carbon cycle‚ and the movement of energy and materials that are used during photosynthesis and cellular respiration. The cycling of matter and energy is essential

CELL INJURY: CAUSES OF CELL INJURY‚ MECHANISMS OF REVERSIBLE AND IRREVERSIBLE CELL INJURY. CELL INJURY. Causes of cell injury range from gross mechanical external causes to mild endogenous causes as genetic lack of enzymes etc. Virtually all forms of tissue injuries start with molecular or structural alterations in cells. Under normal conditions‚ the cells are in: ❖ homeostastatic „steady“ state Normal cell is confined to relatively narrow range of functions and structure by

Cells‚ in a lot of ways‚ are like factories. All the parts of a cell work together to accomplish common goals‚ just like parts of a factory. Each part also has a specific function‚ to make getting the job done a lot easier. The floor of a factory is a lot like the cytoplasm in a cell. It kind of keeps everything where it needs to be‚ and helps direct organelles around the cell‚ much like the pathways on the floor around the machines. The cell membrane in a cell is very similar to the outside

All organisms must have adaptations to survive. The adaptations that organisms develop help them to survive in their environments and then are passed down through reproduction. The genes are passed to future generations and adaptations continue to occur over long periods of time. Nature Works tells us‚” animals that are better adapted to their environment survive and breed. Animals that are not well adapted to an environment may not survive.” There are three types of adaptations that can occur: morphological

Cell Theory In biology‚ cell theory is a scientific theory that describes the properties of cells‚ the basic unit of structure in every living thing. The initial development of the theory‚ during the mid-17th century‚ was made possible by advances in microscopy; the study of cells is called cell biology. Cell theory states that new cells are formed from pre-existing cells‚ and that the cell is a fundamental unit of structure‚ function and organization in all living organisms. It is one of the

Discuss the ethics of allowing advertising in schools. Is there an appropriate age in which advertising could be considered? Advertising should not be allowed in schools. The reason it shouldn’t be allowed is that it directly affects children that haven’t developed the intelligent capabilities‚ mental ability or maturity to make educated consumer decision. I think an appropriate age in which advertising could be considered would be age 18 because young people at this age is capable of accepting

Alternative Energy Alternative Energy Alternative energy refers to energy sources that have no undesired consequences such for example fossil fuels‚ nuclear energy and falling water. Fossil fuels are coal‚ petroleum and natural gas. There are some characteristics of the fossil fuels that made the concept of alternative energy come into place. (Alternative Energy) One of the fossil fuels‚ Petroleum‚ forms a thin film around the grains of the rock where it formed. Pressure from the overlying rock

* The sun has produced energy for billions of years. Solar energy is the sun’s rays (solar radiation) that reach the Earth. This energy can be converted into other forms of energy‚ such as heat and electricity. * In the 1830s‚ the British astronomer John Herschel famously used a solar thermal collector box (a device that absorbs sunlight to collect heat) to cook food during an expedition to Africa. Today‚ people use the sun’s energy for lots of things. solar energy can be used to: * Heat
