A human needs approximately 2-5 percent of protein for the typical energy needed daily. Protein is one of the most important building blocks in the body. It helps the bones, muscles, skin, blood, and cartilage. A humans nails and hair are made of protein. The protein your body uses also repairs tissues and build new ones.
Answer:
Withering is a process in which a rock gets broken down into small and large fragments which are displace other location by the action of wind, water and ice. There are three types of withering: mechanical ,chemical and biological. Mechanical withering is a process which brings changes into physical structure of rocks like large rocks are converted into small rock. Chemical withering is a process which brings changes in the chemical composition of rock. This withering process can change minerals content in the rock. Biological withering is a process in which living beings uses rock for their survival like plants, animals and microbes causes disintegration of rock.
Highly withered and unwithered rock can be distinguished by following characteristics:
1. Physical structure: There will be no change in the structure of unwithered rock but structure of highly withered rock will change after the withering process.
2. Chemical composition: The withering process will remove surface and internal minerals present in rock. In unwithered rock the surface and internal mineral composition will remain unchanged but in highly withered rock the surface and internal minerals present in rock will be removed, which change the overall chemical composition of the rock.
Answer and Explanation:
Mitosis is a process in which a single cell distribute into two identical cells. Mitosis include five phases which depend on the physical state of the spindle and chromosomes. Every phase of the mitosis use pipe cleaners to signify the chromosomes. Body cells have about 46 chromosomes. For simplification we use 4 chromosomes. Pipeline activity of the mitosis include different kind of material. In step 1 take two plates and stack them on the top of each other. Plates signify the cell. On the top plate, place 4 pipe cleaner. In step 2 pipe cleaner of the same length and color subsequent to each other. Then twist each pair together. “X” signify the duplicate chromosomes. Two different colors shows that one chromosome came from the mother and one from the father. Through the process of DNA duplication, chromosomes are copied. In the S stage of interphase, DNA copying take place before mitosis. When the chromosomes become visible, prophase might be identified. Then in the center of the plate, line up the chromosomes in a single line, that represent a cell in metaphase. In Anaphase, separate each chromosome by unraveling them. Telophase is the last phase of the mitosis. Cytokinesis begins in this phase. In mitosis, chromosomes goes back to the correct parent so making the data in accurate.
