The word chloroplast is derived from the Greek words chloros, which means green, and plastes, which means "the one who forms". Chloroplasts are membrane-bound plastids that contain a network of membranes embedded into a liquid matrix and harbor the photosynthetic pigment called chlorophyll. It is this pigment that imparts a green color to ...

5. Ridge. A roof's ridge is found in specific types of roofs such as mansard, gambrel, gable, and pitched. Pitched roofs are very common among suburban homes, forming the classic upside-down 'V' shape. The ridge is located at the uppermost point of the roof, at the point where the two opposing sides connect.

The phase diagram indicates that an iron-carbon alloy with 0.5% carbon held at 900 °C will consist of austenite, and that the same alloy held at 650 °C will consist of ferrite and cementite. Furthermore, the diagram indicates that as an alloy with 0.78% carbon is slow cooled from 900 °C, it will transform to ferrite and cementite at about ...

DNA structure and function. DNA is the information molecule. It stores instructions for making other large molecules, called proteins. These instructions are stored inside each of your cells, distributed among 46 long structures called chromosomes. These chromosomes are made up of thousands of shorter segments of DNA, called genes.

Placing one bonding pair of electrons between the O atom and each H atom gives H:O:H, with 4 electrons left over. Each H atom has a full valence shell of 2 electrons. Adding the remaining 4 electrons to the oxygen (as two lone pairs) gives the following structure: This is the structure we drew earlier.
