Biological Molecules Introduction: Without carbon‚ nitrogen‚ hydrogen‚ sulfur‚ oxygen and phosphorus‚ life wouldn’t exist. These are the most abundant elements in living organisms. These elements are held together by covalent bonds‚ ionic bonds‚ hydrogen bonds‚ and disulfide bonds. Covalent bonds are especially strong‚ thus‚ are present in monomers‚ the building blocks of life. These monomers combine to make polymers‚ which is a long chain of monomers strung together. Biological molecules can be

envy. The public is constantly bombarded with the idea that organic products are better. Perhaps this is true‚ but maybe it is brilliant marketing simply selling a status symbol. Envy can come from a neighbor’s luscious‚ organically grown front yard to the hybrid vehicle a co-worker drives‚ to the organic foods that consumers in a higher financial echelon seem to be able to only afford. Is this envy justifiable or is the notion of organics and its superiority a tactic of propaganda to boost the already

Adhesion How does temperature change affect surface tension? As the temperature of a liquid increases‚ its surface tension decreases. When water heats up‚ the movement of its molecules disrupts the imbalanced forces on the surface of the water and weakens its sheet-like barrier of tightly bound molecules‚ thereby lowering the surface tension. This is why hot water is more effective when cleaning; its low surface tension allows it to more easily penetrate the fibers of a material like fabric

changes in Earth’s orbit and tilt‚ volcanic activity‚ human activity. 2. How orbital changes may affect climate? Ans. When Earth’s orbit is elliptical‚ Earth encounters more variation in energy from the Sun. The tilt of the Earth’s axis also changes. When the tilt decreases‚ temperature differences between seasons decreases. Wobbling of Earth changes the direction of tilt and can reverse the seasons. 3. How changes in CO₂ concentrations affect global temperatures. Ans. Carbon dioxide is a greenhouse

The Existence of God For centuries‚ the idea of God has been a part of man’s history. Past and present‚ there has always been a different integration consisting of the believers and the non-believers of God.
