Meiosis is the process in sexually reproducing organisms where cells divide. The cells produced during meiosis have half the chromosome number as the original cell. There are two cell divisions in meiosis, meiosis l and meiosis ll. These cell divisions produce 4 hapolid daughter cells. Haploid cells contain only one …

Aerobic respiration provides the energy required by all living organisms to function normally, as muscle movement and certain cell reactions are reliant on energy the transport of oxygen to the cells of tissues and organs by blood vessels is vital for respiration to occur. Oxygen is carried in red blood …

The cell is the basic functioning unit of organisms in which chemical reactions take place. These reactions involve an energy release needed to support life and build structures. The cell consists of membrane bound organelles, which are responsible for the division of labour. There are two main classes of cells- …

The dry cell or Leclanche cell was the first commercial battery and therefore had a big impact on society. It is the most common and the cheapest of the commercially available cell and is most widely used in torches, portable radios and battery-operated clocks. It is best used for low …

Carrot tissue culture laboratory is an experiment designed to explore regeneration and the totipotency of carrot tissue through asexual reproduction. Tissue culture is used as a method for commercial and research applications through which a single plant cell can be modified and grown into a mature plant with either the …

Questions 1. Who was to blame for Iridium’s failure? Why? At what point could you have known Iridium would fail? 2. What is your evaluation of Iridium’s system design? What impact did the choices that were made have on subsequent evolution of the venture? 3. What is your evaluation of …

By early 1800s, the accepted idea was that plants and animals were composed of globules called cells. Robert Brown enhanced this idea by describing the nuclei in cells of orchid plants. In 1838, a German botanist, Matthias Schleiden suggested that cells were the basic structural unit of all plant matter. …

Beetroot samples: The same size beetroots will be used throughout the experiment this is to ensure that the impact of the temperature on every sample will stay the same, i.e. if having a bigger beetroot sample less pigments will be released into the test tube at lower temperature, or having …

Cancer cells are abnormal cells and they have characteristics that can be associated with their ability to grow uncontrollably. Cancer cells are non-specialized, and divide uncontrollably. Cancer in situ is a tumor located in its place of origin. Malignant tumors establish new tumor distant from the primary tumors. Cancer cells …

Aim: This experiment aims to determine what effect an increase in the surrounding temperature has on the plasma membrane of a typical plant cell structure. Hypothesis: An increase in temperature will damage and denature the plasma membrane and cause the cytoplasm and other substances contained within the membrane to leak …
