e Three - Research and draft 1 Question 1 1.1) Give a possible diagnose and name the etiological agent involved. Schistosomiasis caused by Schistosoma haematobium. 1.2) Name the intermediate and definite host of this particular parasites mentioned in 1.1 Intermediate host - Freshwater snails Definite host - Humans, primates (Tierney et al., 2007) 1.3) Discuss the life cycle of this parasite mentioned in 1.1. According to Weerakoon et al.(2015), the schistosome parasite has a life cycle…

Gram seeds embryo is called dicotyledons. Seed germination is the process i which the seed breaks a part and the embryo inside to grow with the help of water and a nutrients from the soil seed normally begins to germinates then they get an appropriate range of soil,temperature and when water and oxygen are available.During germination the seeds absorb water either through the micropyle(pore like opening) it is present or through the testa(outer seed coat) when it is permeable.The entry of…

Designer Babies are the Future Designer babies will help reduce the amount of children born with genetic diseases. What if one person has a trait that is immune to cancer? Wouldn 't we want to mass-produce that? Even if it was to insert it through a designer baby. Just as in Genetic engineering we can take out one gene and replace it with a better one. How that works: 1. Have an organism that naturally has that trait. 2. They take that trait out of the organism and clone it. 3. Fix it so that…

“a vast variety of organic substances are made, including sugars and apparently some of the materials from which proteins are build up”(Haldane, 1929). When the first living cell is synthetized, it will reproduce and create more cells. This hypothesis describe the procedure for chemicals on early earth to synthetize living cell hence challenge assumption made by theists that live must be reproduced by other living…

and not glowing under UV light. It ended up growing because the LB that was in the plate with it helped the bacteria grow and reproduce. The bacteria became resistant to the ampicillin because the DNA plasmid contained beta lactamase which made the cell resistant to ampicillin. It did not end up glowing under UV light because the gene for the green fluorescent protein was repressed by the araC gene found on the DNA plasmid. The hypothesis about the +pGLO plate containing LB, ampicillin, and…

Genetic engineering used to be the thing the scientists experimented on plants and animals but now humans. I dont think its right to change the way people live life just to either look a little better or be a little smarter. It's okay in some situations, for instance when someone has really bad pain and it is never ending. We need something to fix it that is not pain killers. Instead we should just have surgery and never feel that amount of pain again but just enough pain to the point where we…

Mary Shelley, in her Science Fiction novel Frankenstein introduces her ideas of technological advancement as a problem between the characters. These problems are considered to be monstrous; however, the modern world would not be where we are today without the advancement of our technology. New discoveries of technology originated in the emergence of the Nineteenth Century and influenced the writing of Frankenstein. Some of these inventions including the discovery of electricity and advancements…

Microbes - bacteria, archaea, fungi, algae, protozoa and viruses - have been around for at least 3,500 million years and were the only life forms on Earth for most of that time. Microbiology is the study of these small organisms. A microorganism or microbe is an organism that is microscopic. The development of the microscope, along with the observations of various scientists, led to the discovery of microorganisms. It is thanks to Van Leeuwenhoek who is largely credited with the discovery of…

250,000pg/µl = 250µg/ml 1mg/ml = 1000µg/ml ● 150,00µg/ml - HIGHEST CONCENTRATION OF DNA ● 1000µg/ml ● 250µg/ml ● 0.2µg/ml - LOWEST CONCENTRATION OF DNA 4. Sodium dodecyl sulphate is used as a detergent, which allows the cells to release DNA by disrupting the cell and nuclear membranes. It dissolves the proteins and lipids that hold the membranes together. 5. The isolated DNA can be used to diagnose genetic disorders, investigate forensic evidence…

Based on Mendel’s experimental observation and conclusion on pea plants, he proposed four postulates including one that each phenotypical characteristic are controlled by a pair of unit factors also known as alleles that separate independently in gametes. Although Mendel’s contribution to genetics isn’t wrong, there are some exceptions of inheritances that do not follow Mendel’s principles. Non-mendelian inheritance traits include maternal effects, epigenetics, and extranuclear genes. What makes…
