Please help I think the answer is B, but I\'m not too sure. A. Amniotic eggs evolved before hinged jaws. B. Tuna are more closely related to salamanders than they are to turtles. C. The most recent common ancestor of salamander and turtle had amniotic eggs, but not four walking legs. D. The most recent common ancestor of all of the species shown had a vertebral column. E. Lamprey are more closely related to leopard than they are to lancelet. A. Amniotic eggs evolved before hinged jaws. B. Tuna are more closely related to salamanders than they are to turtles. C. The most recent common ancestor of salamander and turtle had amniotic eggs, but not four walking legs. D. The most recent common ancestor of all of the species shown had a vertebral column. E. Lamprey are more closely related to leopard than they are to lancelet. Vertebral column Hinged jaws Four walking legs Amniotic egg Hair Lancelet (outgroup) Lamprey Tuna Salamander Turtle Leopard Solution Lets see one by one each Option E. Lamprey are more closely related to leopard than they are to lancelet. are not true as the distance is more for Lamprey to leopard than lancelet. D. The most recent common ancestor of all of the species shown had a vertebral column.also wrong because ancestor were not having verebral column. A. Amniotic eggs evolved before hinged jaws. not very sure if it is true. B. Distance between Tuna and salamanders are far less than they are to turtles. so option B is right C option is also not very convincing as not sure that ancestor of salamander and turtle were not having four walking legs..

Dolphins and fish Analogous structures (convergent evolution) are not found in the common ancestors but the same structure or similar structure with the same function can be found in one or more groups. In such cases, it is not clear to tract the ancestry but the homologous structures are helpful to track the ancestry. For example, both the dolphins and sharks share the fins but the dolphins are mammals, while the shark are fish..

What is stock split? How is it equivalent to paying a dividend? Solution Stock Split is a corporate action in which a public company devide one share in different parts, like 5 for 1 stock split mean for each of existing of investor receive five share. Stock split does not affect market capitalization, that market capitalization remains constant before and after stock split. as number of increase after stock split, stock price of company in same proportion. The primary reason of stock split is to increase the liquidity of the stock. So by reduce the market value of stock company makes the stock tradable more frequently..

Understanding Risk Terms and Definitions Solution What is Risk? Risk is part of every human endeavor. From the moment we get up in the morning, drive or take public transportation to get to school or to work until we get back into our beds (and perhaps even afterwards), we are exposed to risks of different degrees. What makes the study of risk fascinating is that while some of this risk bearing may not be completely voluntary, we seek out some risks on our own (speeding on the highways or gambling, for instance) and enjoy them. While some of these risks may seem trivial, others make a significant difference in the way we live our lives. On a loftier note, it can be argued that every major advance in human civilization, from the caveman’s invention of tools to gene therapy, has been made possible because someone was willing to take a risk and challenge the status quo. In this chapter, we begin our exploration of risk by noting its presence through history and then look at how best to define what we mean by risk. By equating risk management with risk hedging, they have underplayed the fact that the most successful firms in any industry get there not by avoiding risk but by actively seeking it out and exploiting it to their own advantage. A Very Short History of Risk For much of human history, risk and survival have gone hand in hand. Prehistoric humans lived short and brutal lives, as the search for food and shelter exposed them to physical danger from preying animals and poor weather.1 Even as more established communities developed in Sumeria, Babylon and Greece, other risks (such as war and disease) continued to ravage humanity. For much of early history, though, physical risk and material reward went hand in hand. The risk-taking caveman ended up with food and the risk-averse one starved to death. The advent of shipping created a new forum for risk taking for the adventurous. The Vikings embarked in superbly constructed ships from Scandinavia for Britain, Ireland and even across the Atlantic to the Americas in search of new lands to plunder – the risk-return trade off of their age. The development of the shipping trades created fresh equations for risk and return, with the risk of ships sinking and being waylaid by pirates offset by the rewards from ships that made it back with cargo. It also allowed for the separation of physical from economic risk as wealthy traders bet their money while the poor risked their lives on the ships. The spice trade that flourished as early as 350 BC, but expanded and became the basis for empires in the middle of the last millennium provides a good example. Merchants in India would load boats with pepper and cinnamon and send them to Persia, Arabia and East Africa. From there, the cargo was transferred to camels and taken across the continent to Venice and Genoa, and then on to the rest of Europe. The Spanish and the Dutch, followed by the English, expanded the trade to the East Indies with an entirely seafarin.

Thomas Townsend has an embarrassing criminal past. In 1985, he was convicted of pedophilia, having had sexual relations with a 15-year-old child (at the time, Townsend was 29 years old.) By all accounts, Townsend has led a relatively uneventful life over the years since 1985, spending most of his time building and selling musical instruments to earn a living, and reclusively “keeping to himself” on his property on the edge of town. Local police investigators are curious whether Townsend has truly learned from “the error of his ways.” The local sheriff has received a number of complaints from area citizens, who are appalled that a child sex offender is “among their midst.” Working in collaboration with the Federal Bureau of Investigation (FBI,) local police authorities devise and implement a plan to determine whether Thomas is leading an innocent life. Over the course of an eighteen-month period, police investigators mail Townsend a circular they have created, advertising a fictitious publication called “Lustful Lads and Lasses.” Among other pronouncements, the circular entices readers to “order now before publication ceases; see young boys and girls aged 12-16 engaged in all sorts of acts only big boys and girls should be allowed to do!” Having received the circular each month and having declined on seventeen occasions, Townsend finally responds to the circular on the eighteenth occasion, mailing in the $39.95 purchase price. Local, state and federal authorities immediately intervene, arresting Townsend for solicitation of child pornographic materials. At Townsend’s arraignment hearing, his attorney moves for immediate dismissal of the charges, arguing entrapment. Do the police efforts described constitute entrapment? Does entrapment justify dismissal of all charges against the accused? Rather than dismissal of charges, why not simply sanction those authorities responsible for the entrapment? Solution Entrapment is a situation in which law enforcement agents lures a person to commit a criminal offense that the person would have otherwise been unlikely to commit. Townsend had declined the circular seventeen times. But on the 18th occasion, he gave in and responded to the circular. So yes, the police efforts described constitute entrapment. Looking at the \"objective\" test - Townsend was not ready and willing to commit crime. This test ignores the accused personality and predisposition to commit the crime. Thus using the objective test, all charges will be dismissed. Authorities responsible for entrapment will not be penalized. There is no such precedence in law..

Surgeons have sometimes cut the corpus callosum as a treatment for which disorder? schizophrenia bipolar disorder epilepsy outbursts of excessive violence schizophrenia bipolar disorder epilepsy outbursts of excessive violence Solution Cutting of Corpus callosum or \'corpus callosotomy\' is a procedure used for the treatment of Epilepsy. Explanation:The two parts of brain i.e., right and left hemisphere are connected by the corpus callosum. It has the largest content of white matter within the brain with high myelin content. It helps in communication of different parts of brain with each other. Again, Epilepsy or epileptic seizures is a chronic disorder characterized by recurrent and strange seizures (fits). It happens due to the malfunctioning of electrical impulses of the brain. The seizures may spread from one part of brain to the other rapidly through corpus callosum. That is why corpus callosotomy is used for the treatment of Epilepsy. On the other hand, Schizophrenia is a mental disorder that affects the person\'s ability to think, feel and other behaviours such as hallucinations, delusions start occuring. It occurs due to the malfunctioning of neurotransmitters (dopamine, glutamate.) in the brain. Mostlly the patient is treated with antipsychotics and other therapies. Bipolar disorder also known as manic- depressive illness, a disorder in brain which results in depression, extreme mood swings, many times occurence of suicidal tendencies. Mainly treated with antipsychotics, antidepressents and healing therapies. Outbursts of excessive violence also known as Intermittent explosive disorder characterised by outrage of sudden unwarranted anger mainly treated with medication..

Recall that E. coli can grow in glucose-salts medium, which contains only glucose and a few inorganic salts. This means the glucose is serving what two purposes in the cell? Starting point from which all cell components are made Energy source Source of nitrogen A monosaccharide from that the cell can assemble into polysaccharides such as cellulose for its cell wall Source of phosphate Solution The answer is E.coli, mainly uses glucose as the energy source Escherichia coli is a heterotrophic organism, carbon is very important to E. coli because the bacterial cell is composed almost entirely of carbon molecules bound to other important elements. E. coli\'s main source of carbon comes from glucose molecules. This is then broken down into useable carbon by means of central metabolism, which consists of three steps: 1. Embden-Meyerhof-Parnas (EMP) Pathway: converts glucose to pyruvate 2. Tricarboxylic Acid (TCA) cycle: oxidizes Acetyl CoA to CO2 3. Pentose Phosphate Cycle (PPP): oxidizes glucose to CO2.

Every day epople ahve t use this concept and in several situation. Every day people have to ask several questions before taking into consideration various factors before telling a lie, that whether the lie outweighs its consequences. Moral disengagement Moral disengagement is a term used to define a process wherein one convinces that ethical standrds do not apply to the person in a particular situation, by separating moral standrads from the inhumane conduct. Moral imagination Moral imagination is a term which implies that men and women are human beings and that the power of imagination enables the human being to imagine beyond appearances, a heirarchy of worth and truth.

Explain how the structure and function are linked together for the following organs of the digestive system: 1) Mouth 2) Oesophagus 3) Stomach 4) Small intestine 5)Large intestine 6)Rectum 7) Anuss Solution I.Mouth: It is the first organ of the digestive system and food is first taken into the body via the mouth. It consists of tongue, teeth and saliva. These three elements work together to aid the procedure of swallowing. Teeth are used for the process of mastication to make the food smaller is size which is softened by the saliva and turned into bolus by the tongue for aiding the process of swallowing. Saliva is used for softening the food and digesting starch by the salivary amylase. Swallowing occurs bytwo involuntary actions - the soft palate, the back of the roof of the mouth, closes off the nasal cavity, and the epiglottis, a flap of cartilage, tilts downwards to seal the trachea. II.II. Oesophagus – the food passes through the throat and enters the food pipe or trachea. The walls of the oesophagus are muscular and elastic and helps propel the food towards the stomach by rhythmic muscular contractions called peristalsis. Just before the opening to the stomach is an important ring-shaped muscle called the lower esophageal sphincter (LES). This sphincter opens to let food pass into the stomach and closes to keep it there. LES prevents regurgitation. III.Stomach – the food is propelled into the stomach where it stays for upto five hours. The food along with the gastric juices of the stomach is converted to chyme by the churning action of the stomach walls. The stomach walls secrete strong acid (HCl) to make the food acidic in order for the enzyme pepsin to work. Pepsin is important for the breakdown of proteins. Once the contents of the stomach are properly processed they are released into the upper small intestine through the pyloric sphincter. IV.Small intestine – Small intestine is the longest organ of the digestive system and its composed of three segments called the Duodenum, Jejunum and ileum. The food is released into the duodenum from the pyloric sphincter where the pancreatic juices are released along with bile juice from the bile duct. The bile turns the food alkaline so that the pancreatic enzymes can process the food. These enzymes require a alkaline medium to digest the fats and lipids. Contents of the small intestine start out semi-solid, and end in a liquid form after passing through the organ. Water, bile, enzymes, and mucous contribute to the change in consistency. The duodenum is largely responsible for the continuous breaking-down process, with the jejunum and ileum mainly responsible for absorption of nutrients into the bloodstream. Once the nutrients have been absorbed and the leftover-food residue liquid has passed through the small intestine, it then moves on to the large intestine, or colon. The small intestine has a folded lining to absorb nutrients; the lining of the large intestine is flatter V.Large intestine -.
