The beneficial uses of bacterial toxins in medicine are more and more used lately. For example, Botulinum toxin is a toxic protein produced by the bacterium Clostridium botulinum which has paralytic effects (injection of this toxin into muscle relax specific muscles). Botulinum toxin accomplishes his effects on the neuromuscular junction where he prevents the release of the neurotransmitter acetylcholine (Ach). Utilization of this toxin is in the treatment of various muscle spasms. It is also used in the treatment of migraines. Diphtheria toxin is also one of the toxins used for medical purposes for the treatment of cutaneous and non-Hodgkin T-cell lymphomas. <span>Some bacterial toxins can be used in the treatment of tumours. For example, immunotoxin, which is protein made by fusion of modified antibody and toxin.The antibody binds to an antigen on the target cell, the toxin then enters via endocytosis and kills the cell. Commonly used bacterial toxins in immunotoxins are Diphtheria toxin and the Pseudomonas exotoxin.</span>
The Universe is defined to be the sum total of everything that we know about: stars, galaxies, clusters, superclusters, voids, etc.
Cosmology is the study of the structure and evolution of the Universe.
It is a subject of great current interest, as the Hubble Space Telescope and other new instruments have recently helped astronomers shed light on many important questions.
There have been many theories about the Universe, but they generally all share one fundamental postulate, the cosmological principle, which has two parts. First, the Universe must be isotropic (the same in every direction).
For example, the Hubble deep field images, extending 12 Gly away, for two completely different directions, are remarkably similar:
The childhood and early career of Charles Robert Darwin is discussed below.
<h3><u>Explanation</u>:</h3>
Charles Robert Darwin was born on 12 February 1809 in Shrewsbury, Shropshire. He was the fifth of six children of wealthy society doctor and financier Robert Darwin and Susannah Darwin. His grandfathers Erasmus Darwin and Josiah Wedgwood were both prominent abolitionists of the recent times.
Darwin started his career as an apprentice doctor, helping his father treat the poor of Shropshire, before he started to go to the University of Edinburgh Medical School. He found the lectures dull there and in his second year at the university he joined the Plinian Society, a student natural-history group. His father then sent him for a Bachelors of Arts degree which also he couldn't peruse.
After a long fight, he went on his famous voyage on HMS Beagle around the world where he collected his data and then gave his hypothesis in his book named '' On the Origin of Species by means of Natural Selection and Preservation of the Favoured Race in the Struggle for Life''
