Make drawings of both organisms stained in each staining procedure. Label each drawing with the organism name, the total magnification and the name of the staining procedure. For each drawing, record your observations, including the staining result (acid-fast or non-acid-fast; spores present or spores absent), cell shape, cell arrangement and cell size. Explain the mechanism by which the acid-fast stain differentiates between acid-fast and non-acid-fast organisms. Explain why endospores stain one color and vegetative cells stain a different color in the endospore stain. Be thoughtful and complete in your explanation. Would you expect to see endospores in a fresh (24 hour) culture of a Bacillus species? Explain your answer. Suppose you prepare a Gram stain using a 7-day old culture of a Bacillus species. You suspect endospores might be present. What would you expect the spores to look like in a Gram stain and why? Explain when, why and/or how the acid-fast and spore stains are important or useful. In other words, how do we use that information? (Go farther than just stating that these procedures identify acid-fast and spore-forming organisms, respectively.) Solution 1) It is totally dependent on your lab observations. 2) Acid fast staining involves, primary staining with Carbolfuchsin followed by decolourisation with Acid-alcohol and at last counter staining with Methylene blue. In primary staining both acid fast and non-acid fast bacteria stained red. But in second decolourisation step non-acid fast bacteria loses red colour whereas acid fast bacteria remain red. In third counter staining step non-acid fast bacteria who initially lost red colour in decolourisation step will be counter stained blue with methylene blue whereas acid fast bacteria retain its red colour (Carbolfuchsin). Acid fast bacteria: Mycobacterium and many Nocardia species 3) When vegetative cell of certain bacteria is exposed to harsh conditions, to protect cell forms an endosperm to survive and as the favourable conditions come again cell behaves like vegetative cell. Endospore staining has following major steps: 1. Making bacterial cell smear on slide 2. Heating slide gently for fixing it 3. malachite green staining along with heating gently 4. Rinsing slide with tap water 5. Counterstain with safranin Spores resist staining. Therefore heating is done to allow stain to penetrate in endospore. Malachite green is a water soluble dye which is removed easily in washing step from cell wall of vegetative cells but not from the spores. And that’s why spores appear blue (due to primary dye malachite green) and vegetative cell retain the secondary stain safranin and appear pin/red. 4) A 24 hour culture will not show any endospore. Endospores forms when cell exposed to harsh conditions like harsh temperature, lack of nutrients etc. But as it faces favourable conditions of temperature and nutrition, it again gains its vegetative characteristics. As bacteria are in culture from 24 ho.

Find the total cost of making a triangular sail that has a base dimension of 14 feet and a height of 30 feet if the price for making the sail is $17.50 per square foot. Solution Given that , height = 30 base = 14 , price of making the sail is 17.5 per square foot , so we need to calculate the total surface area so the area of the traiangle is given as 1/2 * base* height = 0.5 * 14* 30 = 210 square foot so total cost is calculated by multiplying the per square foot cost with the total area 210 * 17.5 = $3675.

Explain Charge, Current, Volta Power and Energy. Also explain relation between all of them. Solution CHARGE: Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field. There are two types of electric charges: positive and negative. Like charges repel and unlike attract. An object (one not made of antimatter) is negatively charged if it has an excess of electrons, and is otherwise positively charged or uncharged. The SI derived unit of electric charge is the coulomb (C). In electrical engineering, it is also common to use the ampere-hour (Ah), and, in chemistry, it is common to use the elementary charge (e) as a unit. The symbol Qoften denotes charge. Early knowledge of how charged substances interact is now called classical electrodynamics, and is still accurate for problems that don\'t require consideration of quantum effects. CURRENT: An electric current is a flow of electric charge. In electric circuits this charge is often carried by moving electrons in a wire. It can also be carried by ions in an electrolyte, or by both ions and electrons such as in a plasma. The SI unit for measuring an electric current is the ampere, which is the flow of electric charge across a surface at the rate of one coulomb per second. Electric current is measured using a device called an ammeter. Electric currents cause Joule heating, which creates light in incandescent light bulbs. They also create magnetic fields, which are used in motors, inductors and generators. The particles that carry the charge in an electric current are called charge carriers. In metals, one or more electrons from each atom are loosely bound to the atom, and can move freely about within the metal. These conduction electrons are the charge carriers in metal conductors. VOLTAGE Voltage, electric potential difference, electric pressure or electric tension (formally denoted V or U, but more often simply as V or U, for instance in the context of Ohm\'s or Kirchhoff\'s laws) is the difference in electric potential energy between two points per unit electric charge. The voltage between two points is equal to the work done per unit of charge against a static electric field to move the test charge between two points and is measured in units of volts(a joule per coulomb). Voltage can be caused by static electric fields, by electric current through a magnetic field, by time-varying magnetic fields, or some combination of these three. A voltmeter can be used to measure the voltage (or potential difference) between two points in a system; often a common reference potential such as the ground of the system is used as one of the points. A voltage may represent either a source of energy (electromotive force), or lost, used, or stored energy (potential drop). POWER: Electric power is the rate at which electrical energy is transferred by an electric circuit. The SI unit of power is the watt, one joule per second. Electric power is usua.

Describe how a third-generation language (3GL) programming language is used in conjunction with SQL to develop database applications. Solution Conjunction of third generation languages with SQL for developing database applications: There are different alternative of languages that can be used for developing database applications along with the SQL such C,C++,Java, COBOL, Python and etc. These are known as third generation languages. All these languages contain the functionality of the databases. Developers choose the language which is most suitable for the task. A series of pre-compilers are provided by Oracle to set in SQL or PL/SQL with any language such as C/C++,Java and etc. Oracle call interface(OCI): a. It is an Application Program Interface(API) that helps create applications that use function calls of some third generation language for accessing database of oracle along with controlling different phases of SQL statement for execution. OCI supports datatypes ,conversions, syntax and etc. b. It provides consistent interfaces and authentication ,access to external databases. Manipulation of data and schemas is done through the conjunction of C and SQL . Oracle C++ Call Interface(OCCI): 1. It lets the object-oriented features,native classes and various methods of C++ programming language to access the database. 2. It is also used on the JDBC interface through integration to achieve higher performance. 3. Using this access to database is provided for SQL as these are run on the server to run,create and manipulate. 4. They can access arrays,references and various objects. 5. To lock ,delete and flush objects,the navidational interface is used. Oracle type translator(OTT): 1. This generates C language structures automatically through it’s declarations for object types. 2. It provides C++ classes to the pre-compiler to the server to access package. Pro* C/C++ Precompiler: 1. This lets the SQL statements to be embedded in high-level program.It takes in the input and translates the embedded SQL statements into Oracle run-time library calls to generate a program which can compile and run normally. 2. It embeds SQL statements in C or C++ as input and outputs a C/C++ file that replaces the embedded SQL statements. 3. Automatic type conversion takes place from database type to C. 4. Using the EXEC SQL syntax,it destroys objects ..

According to the figure below, which of the following statements regarding endosymbiosis is correct? D) Both red algae and dinoflagellates have three different genomes in a single cell.A) Cyanobacteria are a common ancestor of red and green algae.B) The red algae have two genomes, while the apicomplexans will have three.C) A heterotrophic protist that engulfed a green alga is the common ancestor of the euglenids and chlorarchiniophytes. D) Both red algae and dinoflagellates have three different genomes in a single cell. Part A According to the figure below, which of the following statements regarding endosymbiosis is correct? Cyanobacteria are a common ancestor of red and green algae. The red algae have two genomes, while the apicomplexans will have three. A heterotrophic protist that engulfed a green alga is the common ancestor of the euglenids and chlorarchiniophytes. Both red algae and dinoflagellates have three different genomes in a single cell Submit Hints My Answers Give Up Review Part Provide Feedback Continue Solution (A) The chloroplasts of red algae, green algae, and plants evolved from an endosymbiotic cyanobacterium living within a mitochondria-containing eukaryotic host cell. The evidence for this theory is as follows- (B) The unicellular red alga Cyanidioschyz lacks introns in all but 26 genes. There are only three copies of ribosomal DNA units that maintain the nucleolus and two dynamin genes that are involved only in the division of mitochondria and plastids. The Apicomplexa are a large phylum of parasitic alveolates. Most of them possess a unique form of organelle that comprises a type of plastid called an apicoplast, and an apical complex structure. Their nucleus is haploid. Hence B is false. (C) A protist is a eukaryotic organism that is not a fungus, plant or animal. Heterotrophic protists decompose organic material, feed on smaller organims such as bacteria or live inside the bodies of larger species. Euglenids are one of the best-known groups of flagellates, which are Excavate Eukaryotes of the phylum Euglenophyta. They are commonly found in freshwater, especially when it is rich in organic materials, with a few marine, and endosymbiotic members. Most euglenids are unicellular. They have descended from an ancestor that took up green algae by secondary endosymbiosis. Chlorarachniophytes are unicellular marine algae with green chloroplasts surrounded by four membranes,found in tropical oceans and are typically mixotrophic, ingesting bacteria and smaller protists as well as conducting photosynthesis. A mixotroph is an organism that can use a mix of different sources of energy and carbon, instead of having a single trophic mode on the continuum from complete autotrophy at one end to heterotrophy at the other.The ancestor of chlorarachniophytes is thought to have been a chromalveolate, a eukaryote with a red algal derived chloroplast. Hence C is false. (D) Dinoflagellates are important marine primary producers.They are a lar.

3. A plant breeder crosses an inbred soybean cultivar with herbicide tolerance (recessive allele) and susceptibility to a fungal pathogen (dominant allele) to an inbred soybean cultivar that is susceptible to herbicides (dominant allele) but is resistant to the fungal pathogen (recessive allele). The plant breeder generates F2 individuals and evaluates these individuals for herbicide tolerance and resistance to the fungal pathogen. The plant breeder generates thousands of F2 individuals which he inbreeds to generate purelines. The plant breeder finds that almost every plant that has herbicide tolerance is susceptible to the pathogen. What term is used to describe this phenomenon? A few of the F2 individuals described in question 3 are both herbicide tolerant and resistant to the fungal pathogen. What likely happened to the DNA in these plants in order for this to occur? Solution The phenomenon produced can be termed as epistatis where herbicide tolerance (hh, recessive allele) and susceptibility to a fungal pathogen (F(F/f),dominant allele) interact to show a mixed Dominant recessive epistasis i.e The F along with h masked the susceptible to herbicides (H,dominant allele) but is resistant to the fungal pathogen (ff, recessive allele). Therefore, most of the offspings of F2 generation were showing herbicide tolerance is susceptible to the pathogen F masked the effect of H . The plans with ff only showed both herbicide tolerant and resistant to the fungal pathogen.The DNA of these plants expressed the protein needed to express the reistant to fungal pathogen in absence of F..

Which is a common trait among all land plants? Vascular tissues transport water and nutrients, and provide support Seeds facilitate survival and dispersal of the species Flowers facilitate cross-pollination The embryo is protected within maternal tissues The haploid phase of the life cycle is the dominant phase Flowers facilitate cross-pollination The embryo is protected within maternal tissues The haploid phase of the life cycle is the dominant phase Solution First we see common traits of land plants and then see listed traits in details one by one: 1. Ability to withstand desiccation. Extant land plants have a cuticle and guard cells. 2. Ability to withstand the effects of more intense radiation, particularly DNA-damaging radiation. Extant land plants have several compounds in their vacuoles that absorb UV. Since the vacuole of a plant occupies most of a mature cell, this helps protect the DNA in other organelles. 3. Ability to protect their spores from desiccation. Early land plants have spores that are encased in a sporopollenin wall. Sporopollenin is a very resistant polymer, resistant to UV and almost everything including desiccation, squashing, etc. To remove sporopollenin from spores, one boils them in a mixture of acetic and hydrochloric acid. 4. Ability to move solutions from the ground to portions of the plant that are not in contact with the ground, and from the photosynthetic portions of the plant to non-photosynthetic portions. Some land plants do this better than others. 5. Ability to support themselves. Aquatic plants float; terrestrial plants cannot do so. Most terrestrial plants have lignin in some of their conducting cells. There is some debate as to whether this was selected for by the advantages of growing tall or the need to protect against embolism in the conducting cells. Since both are important, it seems most realistic to accept that both contributed to the success of plants with the ability to manufacture lignin, the tracheophytes or vascular plants. 6. Ability to acquire the carbon dioxide required for photosynthesis from the atmosphere. This ability is associated with stomatal cells, specialized cells that surround openings (stomates) in the outer cell layer of land plants. Now we see Options given one by one: Vascular tissues transport water and nutrients, and provide support Transport of Water and Minerals: The xylem tissue transports water and minerals. It consists of interconnected vessels and tracheids organized into continuous conducting tubes stretching from the roots to the leaves. These tubes carry water and minerals to all parts of the plant. Plants absorb water from the soil through the root and transport it to the stem, leaves and flowers. Roots have root hairs that are unicellular, thin-walled outgrowths of the epiblema (skin of the root). The root hairs are in close contact with the thin film of water surrounding the soil particles. There are mineral salts such as nitrates, chlorides, sulphates, phos.

what role(s) played by the Equatorial Segment Protein 1 (ESP1) during fertilization. Solution The structure of a spermatozoa consists of three parts. They are, Acrosome is the elongated head region of the sperm containing 2/3rd of the nucleus. The enzymes present in the acrosome are essential for the penetration of a sperm into a secondary oocyte (egg). The acrosomal layer necessary for the fusion and penetration into the oocyte is deficient in mice lacking Equatorial Segment Protein 1 (ESP1). This indicates that ESP1 is necessary for the development of \"fusion-competent sperm.\".

What does it mean if a human female oocyte is no longer arrested in metaphase II of meiosis? Solution Answer: Primary oocytes forms prenatally and remain suspended in prophase of meiosis I until it reaches puberty. An oocyte completes meiosis I as its follicle matures resulting in a secondary oocyte and the first polar body. After ovulation, each oocyte continues to meiosis II metaphase. Meiosis II is completed only if fertilization occurs. This results in a fertilized mature ovum and the second polar body. Thus, the human female oocyte is arrested in metaphase II until fertilization by a sperm takes place..
