body‚ there are billions of cells that are essential to living – these are called nerve cells. Nerve cells‚ also known as neurons‚ “are the basic information processing structures” (Stufflebeam). There are about 100 billion of these neurons in our nervous system and are the most essential cell in it. Located in brain as well as the spinal‚ there are different types of nerve cells; including: sensory neurons‚ motor neurons‚ and interneuron (Boeree). The neuron is a cell that is structured similarly

roles of mitotic cell division‚ meiosis‚ and fertilization in the human life cycle. Mitosis allows for growth and repair from the fertilized egg to the adult. In reproductively mature individuals‚ meiosis creates gametes with half the genetic material. The male gamete then fertilizes the female gamete during sexual reproduction‚ forming a zygote with a full set of genetic material. 2. Why are both cell division and apoptosis necessary for the development of an organism? Cell division is needed

increase in size as their cells grow and divide. Almost all cells complete a full cell cycle that includes interphase and cell division. In interphase‚ cells serve their specialized functions‚ grow‚ and copy their genetic material. Mitosis is the first stage of cell division‚ in which the copied chromosomes are separated into two new nuclei. Then in cytokinesis the cell divides into two daughter cells. If no mutations or errors occur‚ the genetic material in each daughter cell is identical to what was

The part of the pancreas with endocrine function is made up of approximately a million[3] cell clusters called islets of Langerhans. Four main cell types exist in the islets. They are relatively difficult to distinguish using standard staining techniques‚ but they can be classified by their secretion: α cells secrete glucagon (increase glucose in blood)‚ β cells secrete insulin (decrease glucose in blood)‚ delta cells secrete

A two party system would be much better for the future of our country than a multiparty system. A two party system has two major political parties in the country. Such a system does not mean there are no other political parties. Other minor parties exist‚ but two parties dominate the government. A multiparty system has more than two main political parties .In a multiparty system‚ the people have a variety of choices to choose from when deciding their political opinion. However there are so many

Cell Respiration Respiration is the process by which organisms burn food to produce energy. The starting material of cellular respiration is the sugar glucose‚ which has energy stored in its chemical bonds. You can think of glucose as a kind of cellular piece of coal: chock-full of energy‚ but useless when you want to power a stereo. Just as burning coal produces heat and energy in the form of electricity‚ the chemical processes of respiration convert the energy in glucose into usable form. Adenosine
