Prologue: The prologue chapter introduces biology and it’s meaning. It states the difference between pseudoscience and testable science. For example, evil forces do not kill the living contents in the biosphere nor do the gods help keep it alive. Instead, the biosphere is based on scientific explanations from observations, inferences, and experiments. In these experiments, there are testable hypotheses, such as whether your plant will die or why the plant grew to the top of the bottle.…

Sejaphala M.D. Student No. 62399543 Unique Number: 770819 Introductory Microbiology MIB2601 Assignment 02 Due Date: 13 April 2018 QUESTION 1 1. Bacteria is stained using a primary stain called crystal violet and then fixed with a mordant which in most cases is iodine. While some bacteria have the ability to retain the primary stain, others discolor when exposed to the acetone and alcohol (95%). Hence, the Gram stain divides bacteria into two groups- these bacteria are grouped…

this disease manifest in the nuclear membrane or as many people refer to as, the nuclear envelope. The nuclear envelope comes from the eukaryotic cell; this nucleus contain two membranes that are near to each other, also has nuclear pores, laminas, ribosomes; anyway it contains what most cells has in; likewise, inside the nucleus you can find approximately 99% of DNA that is the genetic material of this type of cell.…

Introduction The drugs used in this experiment are Chloramphenicol and rifampicin. Both of these drugs are antibiotics however their methods of action are quite different. These drugs have different effects on the bacteria they are being used against. Rifampicin is a bactericidal drug and chloramphenicol is bacteriostatic. Bactericidal drugs interfere with the bacteria to such an extent that the bacteria die. They not only prevent new cells from growing but also cause a crucial aspect of the…

What is the central nervous system? It’s a system which consists of the nerves in the brain and spinal cord. It gathers information about and reacts to internal and external stimulus. Don’t Shoot the Messenger Much of the CNS is made up of neurons. Each neuron has a cell body, which includes a soma with a nucleus, a nucleolus, a cytoplasm called the perikaryon, and wide branching extensions called dendrites. Dendrites are like antennae which receive signals from other neurons or body cells.…

organisms are the prokaryotes and the eukaryotes. The prokaryotic is the simpler of the two and are the one-celled organisms such as bacteria and archaea. The interior of a prokaryotic cell consists of a main nucleoid, which contains the DNA, the ribosomes, which synthesize proteins, and the cytoplasm, which is a liquid cytosol that suspends the organelles. The cell is surrounded by a plasma membrane, which facilitates what enters or leaves the cell, a cell wall, which gives rigidity…

Deoxyribonucleic Acid better known as DNA is housed in the cell’s nucleus where the genetic material is. DNA is a long molecule that forms a double helix, folded inside of the nucleus of the cell. The double strand of DNA is held together by hydrogen bonds. The double helix of DNA run head to tail. DNA is typically millions of base pair long (Shier, Butler, Lewis, 2016, p.94). Deoxyribonucleic Acid is one type of nucleic acid with the sequence of building blocks that hold information that…

During initiation, RdRp employs an endonuclease activity to cleave and “snatch” the cap of host cell mRNA to prime viral transcription, the transcribed viral mRNA is later translated into structural and non structural viral proteins by the host ribosomes, after translation is completed, RdRp transcribes a positive strand RNA from the initial viral…

Humen is A human is way better at everything and I animal kills humans are really kill you already know how I feel yeah mister daddy animals they got us we don't got to pay we have food at stores so all we got to do is go Outdoors Right there and we have cars they don't we have Better Homes then And their bodies are made different or is it all we have orange left heading your way smarter than them we go to school they don't so that's how I'm going to put my story you understand meI said they we…

One debate that scientists have pushed and pulled upon ever since the study of virology began, is whether or not viruses should be classified as a living organism or not. Living things are highly organized, and have may other characteristics that accompany it. The general agreement among scientists is that there are seven main characteristics of life; cellular organization, metabolism and energy use, response to stimuli, regulation and homeostasis, growth and development, evolution, and…
