Hindbrain Outline The introduction briefly talks about the hindbrain‚ its location‚ structure and highlights its main functions. It also talks about how the hindbrain is divided. The next topic is about Structure and Function. It first starts with the functions of the hind brain and then mentions each and every function of the brainstem‚ that it‚ the medulla‚ pons and the cerebellum. It also mentions the functions of the cranial nerves. The next section is on Injury and Disorder. Here it is mentioned

accurately describes the primary structure of a polypeptide? A) The primary structure of a polypeptide is the number and sequence of nucleotides read from the N-terminus to the C-terminus B) The primary structure of a polypeptide is the number and sequence of amino acids read from the N-terminus to the C-terminus C) The primary structure of a polypeptide is the number and sequence of monosaccharides read from the N-terminus to the C-terminus D) The primary structure of a polypeptide is the number

Chemistry plays an important part in studying Biology. It answers some questions that Biology could not explain alone. Questions like: How does an organism convert foods for energy? How do plants use sunlight and water into all the things that cells needed to grow and reproduce? How does the basic unit of life passed through generation to the next? Here are some contributions of Chemistry in Biology: • Within atomic theory‚ chemistry contributes towards biology in the understanding of atoms and elements

CELL THEORY – STEM CELLS Stem cells are a large focus of study in today’s biomedical world. “They are cells that exist in an undifferentiated state‚ and transform into differing tissue types depending on what the cells surrounding them are‚“ (National Institute of Health‚ 2012). Stem cells have the remarkable potential to develop into many different cell types in the body during early life and growth. In addition‚ they also serve as an internal repair mechanism inside many tissues‚ dividing without

that decreasing levels of carbon dioxide correspond to increasing pH. Which cellular structure in elodea carries out the process that is most likely to result in increasing pH? Which structures‚ if found in a cell‚ would provide the best evidence that the cell is eukaryotic? Where in the cell do the following occur? Calvin cycle‚ glycolysis‚ Kreb’s cycle‚ electron transport chain. Students in a biology class tested the effects of antibiotics on the growth of bacteria. They cultured bacteria

MATERIAL AND METHODS 1. Materials: 1.1. Experimental animals: The experiment was carried out on 30 adult healthy female rats weighing 190 20g and 10 young (6-7) weeks –old male albino rats from which bone marrow mesenchymal stem cell (MSCs) were isolated. Animal were purchased from the animal house of the faculty of Medicine Mansoura University. The animals were housed in standard stainless steel cages at room temperature 25-28ﾟC‚ humidity of (50-60%) and maintained at 12 hrs alternating day

List down the contribution(s) of the following philisophers/scientists to the science of Biology Pre-historic people: The earliest humans must have had and passed on knowledge about plants and animals to increase their chances of survival. This may have included knowledge of human and animal anatomy and aspects of animal behavior (such as migration patterns). However‚ the first major turning point in biological knowledge

Discuss the chain of events that led to the discovery of DNA as the heritable substance and the discovery of the structure of DNA. Ans> The chain of events led to the discovery of DNA as the heritable substance and the discovery of the structure of DNA. In the late nineteenth century‚ a German biochemist Friedrich Miescher found the nucleic acids which are long-chain polymers of nucleotides‚ and are made up of sugar‚ phosphoric acid‚ and several nitrogen-containing bases. Later it was found
