1.The cell is the basic unit of life, and all living things are consists of cells and all cells develop from pre-existing cells. Cell theory primarily explains the functions and properties of cells. This theory states that the cell is the basic unit of life; it is the smallest unit that is still considered a living thing. The components of a cell, organelles and molecules, are not living.Every organism, no matter how complex, is made up of a complex system of cells. Some organisms are unicellular, comprised of a single cell.Earlier to the universal acceptance of cell theory, a common faith was that of spontaneous generation, the concept that life springs from abiotic factors. The biology department of the University of Miami identifies German philosopher Lorenz Oken as the first person to communicative this principle in 1805 when he stated that \"All living things originate from and consist of cells.\" 2. The common similarities of eukaryotic and prokaryotic cells are: a. DNA is called De-oxy ribonucleic acid consists of the genetic material contained in one or more chromosomes and located in a non-membrane bound nucleoid region in prokaryotes and a membrane-bound nucleus in eukaryotes. b. Plasma membrane consists with a phospholipid bilayer with different types of proteins that separates the cell from the adjacent environment and functions as a selective barrier for the export and import of materials. c. Cytoplasm, the rest of the organelles of the cell within the plasma membrane, excluding the nucleus or nucleoid region, that made up of a fluid portion called the cytosol and the organelles and other particulates positioned in it d. Ribosome’s, are the organelles involved in protein synthesis and 80s ribosome in eukaryotes and 70s ribosome’s present in prokaryotes. 3.The nucleus has mainly two functions in separating the DNA from the cytoplasm. a.Nucleus protects the DNA. It gives a location and store the genetic material from damage. It makes replication of a large genome and consists of linear chromosomes that must be replicated perfectly when the cell divides. b. It allows regulation of protein expression. Gene splicing permits multiple proteins to be made from a single gene with introns. PolyA tail adenylation and capping can control the mRNA life span. Nucleolus present in the nucleus where the ribosome specific RNA is transcribed and assembled as ribosomes. 4.Ribosomes are the organelles of protein biosynthesis, the process of translating mRNA into the protein molecule. The mRNA consists of a series of codons that states to the ribosome the sequence of the amino acids needed to make the protein. The mRNA acts as a template, the ribosome crosses each codon of the mRNA, pairing it with the suitable amino acid provided by a tRNA. The transfer RNA (tRNA) contains appropriate amino acid on one end and complementary anticodon on other end. In proteins synthesis, first, the small ribosomal subunit, bound to a tRNA containing the amino acid me.

In a Davis U-tube experiment, you add a different strain of auxotrophic bacteria to each side of the apparatus. After allowing time for growth, you transferred and grew the bacteria on a plate with minimal medium and noticed the growth of prototrophs. By which process did this genetic transfer possibly occur if... There was DNase enzyme (breaks down free-floating DNA) present in the medium? There was no DNase enzyme in the medium? There was DNase enzyme present in the medium and the sintered glass filter was removed from the U-tube apparatus (no separation between bacterial strains)? Answer the following questions with F^+, F^-, or Hfr. More than one of these three may apply to a single question. Bacterium that does not have an F factor. Bacterium that can donate an F factor. Solution Answer: 4. For DNA transfer to take place through conjugation between the two different bacteria, physical contact is necessary. a. When DNase is present, it can cleave any naked DNA present in the media. So, the only way that can transfer DNA from one bacterial auxotroph to the other is through transduction (if the media is contaminated with a bacteriophage) or through physical contact, i.e, conjugation (if the sintered glass filter is defective). b. When there is no DNase, the most probable mechanism of gene transfer is transformation (transfer of naked DNA). c. In this case, there can be physical contact between the two auxotroph strains. So, gene transfer probably took place through conjugation. 5. a. Bacteria that does not have a F factor: F- b. Bacteria that can donate a F factor: F+ ( Hfr strains cannot transfer the F-factor efficiently to the F- strain due to the short duration of conjugation tube formation).

I dont really know what two factor analysis is? All my study guid says is to know what two factor analysis, three factor anaylsis and tetrad anaylsis. Then it gives the things you should know in each topic. THis is for Genetics. Two factor analysis: 1) You should know how to determine the genotype (write it properly) of individuals based on phenotype and phenotype based on genotype. 2) You should know cis and trans organization of alleles in a diploid organism. 3) Determine map distance between genes based on recombination frequency 4) You should be able to determine progeny size of different genotypes based on genetic map and map distance. (distinguish between map position and map distance) 5) Know test cross and F2 analysis of linked and independently assorting genes. . 6) Show know how to do genetic analysis of organisms where recombination is seen in both male and female gametogenesis and organisms where recombination is absent in males. Solution 1. The phenotype means the external appearance of an organism. It is the observable characteristics of any indivudual. As if we say the plant is tall having green and round seeds and purple flowers, so the characters such as tall, green, round and purple are the phenotypic characters of that plant. Genotype refers to the genetic makeup of an individual. It constitutes the set of genes, whuch decides the phenotype of organism. Such as TTRR this is genotype of a homozygous tall plant having round seeds..

essay on elderly patients in rural areas having problems meeting health care needs due to transportation Solution Many elderly patients who are above 60 years old have been facing higher complex situations with respect to their health due to low transportation facilities across the country. This is due to lack of both federal and state \"transportation health care budgets\" to implement health care facilities including adequate rural transportation services finally making elderly people difficult to their health care access those who have been suffering from dementia, diabetes and neurodegenerative diseases. Therefore, the health care needs including accident and emergency services to the rural pediatric patients are lower compared to the urban health care facilities so that it is crucial to improve essential public transportation systems to bring these pediatric patients to provide them with essential care.

Define liquidity and why money is said to be the most liquid of all assets. Solution Liquidity is defined as the speed with which one asset can be converted into another asset that can be instantly used as cash (for transaction purposes). In this sense, money is the most liquid asset. Cash is already an asset that can be exchanged for any purpose, but other components of money, for example checking deposits, savings, certificate of deposits etc, can be concerted into cash at fastest possible time, therefore they are considered most liquid of all assets. In contrast we can consider a farm-house which is a salable asset, but selling it and getting cash for it takes much time, so it has very low liquidity..

Compare and contrast eukaryotic and prokaryotic cells. Why do you think their endomembrane systems are different, is evolution involved? Paragraph format please, be very detailed and the answer is expected to be long! Solution Prokaryote,relatively simple unicellular organism lacking a nucleus and other features found in the more complex cells of all other organisms,called eukaryotes.In 1938 American biologist Herbert Copeland proposed that unicellular organisms lacking nuclei be classified in their own kingdom, Monera, also called Kingdom Prokaryotae.All bacteria were categorized in this newly established kingdom. This scheme was the first to establish separate kingdoms for prokaryotes (organisms without nuclei) and eukaryotes (organisms with nuclei).In 1990 American microbiologist Carl Woese proposed that bacteria be divided into two groups,the archaea,or archaebacteria,and bacteria, based on their structural and physiological differences.In some classification systems,the archaea are considered prokaryotes;in others, they are classified in their own domain, the archaea.Archaebacteria consist of a small group of primitive anaerobes (organisms that do not require oxygen).They are found in a narrow range of habitats–often in extreme environments with high temperature,high salt,or high acidity.In contrast, bacteria live in a wide range of environments with or without oxygen, at various temperatures, and at various levels of acidity. In both prokaryotes and eukaryotes,the plasma membrane is composed of two layers of phospholipid molecules interspersed with proteins,and regulates the traffic that flows in andout of the cell.The prokaryotic plasma membrane,however,carries out additional functions.It participates in replication of deoxyribonucleic acid (DNA) for cell division andsynthesis of adenosine triphosphate (ATP),an energy molecule.In some prokaryotes,the plasma membrane is essential for photosynthesis,the process that uses light energy to convert carbon dioxide and water to glucose. Fossil records indicate that eukaryotes evolved from prokaryotes somewhere between 1.5 to 2 billion years ago.Two proposed pathways describe the invasion of prokaryote cells by two smaller prokaryote cells.They subsequently became successfully included as part of a now much larger cell with additional structures and capable of additional functions.They are Endosymbiosis and Membrane infolding.ProkaryotesEukaryotessize is 0.1-5.0 micrometressize is 5-100 micrometresnucleus is absentnucleus made of nuclear envelope,chromatin,nucleoplasm,nucleoliDNA is circularDNA is linearDNA is naked and not assosciated with histonesDNA is associated with histonesplasmids may occurplasmids are rare.cell membrane have in folding called as mesosomemesosome is absentmitochondria are absentpresentribosomes are 70S80Sgolgi apparatus,ER,lysosomes,centrosome absentall are presentsexual reproduction is absentsexual reproduction occurs.endocytosis and exocytosis are absentthey occur in e.

Which intermolecular porcess primarly drives the formation of a bilayer when phospholipids are added to water? Which intermolecular porcess primarly drives the formation of a bilayer when phospholipids are added to water? A-Lipids cause water to arrange in an ordered, unfavorable cage-like structure. B-Forcing lipids into a bilayer reduces this effect. C-The ordered arrangement of a bilayer is more favorable than the disordered state of individual free-floating phospholipids. D-A bilayer arrangement maximizes the strength of hydrophobic interactions among phospholipids. E-Phospholipids self-assemble inot a bilayer due to the strong affinity they have for each other. Solution Thanks for your query. As the lipid bilayer forms the surface of the cell. there is an important point that we have to understand here., That is the lipid cell is hydrophilic on one end and hydrophobic on the other end. Therefore, the hydrophobic ends of both cells join in the center of the lipid bilayer and the hydrophilic ends expose themselves to the outer surface and the inner surface. Since they are hydrophilic they can easily interact with the fluids they are exposed to unlike the hydrophobic ends. Therefore the correct option is D Thanks.

What is simplicity and how does it bear on the acceptability of a scientific hypothesis? Solution Simplicity - simpler means fewer assumptions. Consider Newtons mechanics and copernican hypothesis . They both stand as examples of generality and simplicity. Newton with help of previous general set of laws explained laws of motion for terrestial and heavenly bodies. Copernicus explained the same observational data with simpler assumptions. The virtues are not independent and in some cases it overlaps. In some cases generalisation will be simplification. Simplicity is used for describing philosophical theories . In general if a hypothesis is more simpler it can be confirmed . In some cases precision overlaps simplicity. The reality is part of quine pervasive scientific realism. Quine quotes for simplicity. Quine also quotes that different classes or groups can be clearly dealt only if is in simpler explanatory view and relative simplicity of the system. Hence a scientific theory should not be generalised but should be in simplified form..

What’s the difference between soluble and insoluble fiber? Why is fiber indigestible? After all, isn’t cellulose just a string of glucose molecules, similar to amylose? What are some of the benefits of increasing fiber intake? How does fiber confer these benefits? What are some of the potential pitfalls of consuming excess fiber? How does fiber confer these detriments? What are the general recommendations for fiber intake? We refer to some of our fibers as prebiotics. What does that term really mean? How does a prebiotic aid gut health? Solution What’s the difference between soluble and insoluble fiber? ANS: In short soluble fibres dissolve in water and insoluble fibres do not. Soluble fibre makes our food more viscous when in a digestive tract. Soluble fibre traps food components thus making them less absorbable. Insoluble fibre absorbs water for example how dry sponge expands after soaking up water. Insoluble fibres are helpful in treating constipation. Why is fiber indigestible? After all, isn’t cellulose just a string of glucose molecules, similar to amylose? ANS: What makes fibre indigestible is the lack of enzymes in humans to break down the glycosidic bond in fibre. What are some of the benefits of increasing fiber intake? ANS: Benefits of fibre intake include: gastrointestinal disorders lowering cholesterol levels lowering the risk of colon cancer weight loss How does fiber confer these benefits? ANS: fibre has three mechanisms of action, which are bulking, viscosity and fermentation. Fibres can use all three mechanisms or only one. Bulking fibres absorb water and increase stool weight and regularity. Bulking fibres can be minimally fermented or not fermented. Viscous fibres thicken the content of the intestinal tract . They mix with water and form a gelatinous mass. Depending on the type of viscous fibre, they are minimally, partially, completely fermented or not fermented at all. Fermentable fibres are used as food source for the microbes that exist on our large intestine. What are some of the potential pitfalls of consuming excess fiber? ANS: As fibre is not digested, too much fibre causes the digestive tracts to process it slowly, it can lead to bloating, constipation, abdominal discomfort and gas. If constipation is prolonged, it can lead to intestinal blockage. during intestinal blockage there can be malabsorption and accumulations of toxins in the body..
