are needed large amounts by plants. They are required for root growth. For the root tips cells to divide‚ mitosis has to occur. Phosphate is needed for production of ATP which provides energy for mitosis to occur. DNA replication occurs during interphase of the cell cycle. DNA is made up of nitrogen containing base‚ pentose sugar and phosphate group. The phosphate group forms part of the sugar phosphate backbone of DNA. Phosphate is therefore necessary in DNA replication. During root growth‚ membranes

Objectives of the Study This study evaluates the genotoxicity‚ and teratogenicity/antiteratogenicity of the methanol leaf extracts of Tamarindus indica (TE). In particular‚ the study aims to: determine the genotoxicity of TE in terms of: mitotic index chromosomal aberrations micronuclei formation assess the developmental toxicity and teratogenicity potential of TE to zebrafish embryos; and verify the potential of TE to rescue zebrafish embryos from ethanol-induced teratogenicity.

Biology 1. If an interphase cell is treated with cyanide (a metabolic poison)‚ the cell does not divide by mitosis. However‚ if cyanide is added right after mitosis has started‚ the same cell completes mitosis. Which of the following explains this observation? A. Metabolic activity ceases during mitosis B. Cell division does not require metabolic activity C. Energy required for mitosis is produced and stored in the cell during interphase D. Mitotic cells make factors that make them resistant to

Alveolar Surface Tension and Surfactant in the Compliance of the Lungs Alveolar surface tension is important for the lungs to function efficiently. Surfactant is a lining in the alveoli made of lipids and proteins. Surface tension of the alveoli are important to keep the alveoli shape‚ but surfactant is needed to regulate surface tension. Also surface tension promotes movement of fluids across the alveolar membrane‚ therefore the surfactant also regulates the movement of fluids. Attraction of

Introduction: Mitosis occurs in all eukaryotic cell tissues and produces genetically identical daughter cells with a complete set of chromosomes. In humans‚ mitosis produces somatic cells that are diploid‚ which means they contain two non-identical copies of each of the twenty-three chromosomes. One copy is derived from the person’s mother and the other from the person’s father. Meiosis‚ on the other hand‚ occurs only in testis and ovary tissues‚ producing sperm and ova (eggs). The gametes that
