Whats the role of the gastric caeca in a grasshopper Solution Grasshoper: Insects of the suborder Caelifera within the order Orthoptera. Role of the gastric caeca in a grasshopper: Gastric caeca are finger-like projections of the digestive tract found in many insects. These pouches extend from the mid-gut and contain protozoa or bacteria that aid digestion,Gastric caeca increase the surface area in the digestive tract increasing digestive enzyme secretion and nutrient absorption.The gastric caeca project at the transition from foregut to mid-gut. Insects feeding on difficult to digest materials, pouches called gastric caeca arise in the front of the midgut. Each gastric caecum often contains protozoa and/or bacteria that aid in digestion..

what does it takes to be a living organ? What does it take to be a living organism? Living things share 8 characteristics that are listed in Chapter 1 of your textbook on page 19 Think of an organism or cell in which all 8 characteristics are not obvious for example, coral looks like it does not move, red blood cells do not reproduce and have no DNA. frogs freeze in the winter therefore it seems as if they do not maintain homeostasis, and so on Focus your discussion on the following Make comparisons between living things and nonliving things that have some of the characteristics that define life Compare the following pairs and explain what the differences are using the 8 criteria A rock to a snail A rock to a tree A dog to a TV Explain why electricity is sometimes called line, or discuss some of the characteristics fire shares with living things (it can grow, it metabolizes, and so on) Solution The 8 characteristics of living organisms are: These 8 traits are generally used to classify organisms are either living or non-living. Things that do not exhibit all 8 traits are scientifically classified as non-living. However, there are many classified living things that do not visibly show all 8 characteristics. For example, trees are made of cells, grow, evolve, reproduce, etc, but they do not physically move. Bacteria and other single celled organisms do not show different levels of cellular organization. In ant colonies, only the queen reproduces, yet even the non-reproducing worker ants are considered living. Viruses are another hotly debated topic, as scientists continue to argue if they are living or non-living. While outside the host body they may seem dead, when they enter the host they stir to life, using the host\'s cellular machinery to reproduce, grow, assemble themselves before destroying the cell and continuing the infection. Sometimes, even non-living things seem to share a few traits of living things. For example, icicles may be non-living, but in cold weather they can visibly \'grow\' as water freezes and the icicle expands in size. Comparing the following pairs: Electricity and fire are often termed \'alive\' due to their behaviour, however, they are forms of energy, not living organisms. Uncontrollable electricity is often termed \'live\', it travels through conductive materials, it can even reproduce by distributing energy along various paths as it travels. Similarly, fire, when provided with the right materials, can grow and spread. It metabolizes fuel to maintain itself, and its movement and growth can be altered in response to external stimuli. However, neither electricity nor fire consist of cells, nor do they evolve, and being forms of energy, they cannot maintain homeostasis. Thus, they are classified as non-living..

ve targets. ball and sodket hinge joint condyloid joint saddle joint Ch 05 HW Ch 08 HW pivot joint Solution Ball and socket joint is between humerus and scapula. Hinge joint is between the humerus of the upper arm and the ulna and radius of the forearm. Pivot joint : Pivot joints allow for rotation, which can be external (for example when rotating an arm outward), or internal (as in rotating an arm inward).Example is proximal and distal radioulnar joint Condyloid joint : Oval shaped condyle of one bone fits into elliptical cavity of other bone. These joints allow biaxial movements i.e. forward-backward and side to side but not rotation. Example is the wrist joint. Saddle joint : The carpometacarpal joint of the thumb makes the human thumb opposable by allowing it to move across the palm to contact the other four fingers of the hand. Plane joint :Plane joints permit sliding movements in the plane of articular surfaces.

This one is for you - assume that this pedigree shows the inheritance of a rare autosomal condition. Note that the father (II-4) is a known carrier and that this couple has had 3 normal children. What is the probability that she is a carrier? Solution The disease is rare autosomal. In other words it is autosomal recessive disorder. Now the male and female in II-1 and II-2 have disease. Lets call their genotype as \"aa\". But Their parents in I generation are normal. This means they are carriers of the disease with genotype Aa and Aa. Their third daughter II-3 has no disease, Her genotype can be Aa or AA, so probability to carry a recessive allee a is 1/2. If she had had a diseased child, her genotype would have been Aa with 100%probability. But as has all healthy kids, probability of her being carrier is 1/2..

I finished most of the program, but having trouble with some key features. I bolded and italicized the parts I can\'t figure out, and included them below. I included my code at the bottom. Thanks! 1. I can\'t get my RemoveItem() and ModifyItem() functions to work. 2. GetNumItemsInCart() is returning the wrong value. For example, my cart has 5 chocolate chip cookies, 1 headphone, and 2 sneakers. GetNumItemsInCart() returns 3 instead of 8 when I output my shopping cart. 3. When PrintDescriptions() is called, the first letter of my item description is missing. For example, for the chocolate chip cookies, the description is Semi-sweet. When PrintDescriptions() is called, it returns emi-sweet, with the S gone. 4.

How will the rate of diffusion of an interstitial i Impurity atom Increases? CIRCLE THE BEST ANSWER Increase Decrease The rate of diffusion will be unaffected by changes In the size of the impurity species. impurity species change as the size of the impurity species. Solution The rate of diffusion will decrease as the size of the impurity atoms increases because greater the size of impurity atoms greater will be the difficulty in accomodating the impurity atoms at interstitial sites and also larger size will decrease its mobility and provide hindrance during its movement from one site to another. all these factors contribute in decrease in rate of diffusion..

Explain the use of the half year convention for MACRS deprecation for assets other than real estate and the exception to the half-year convention rule. Year of the acquisition Year of disposal Mid-quarter convention Solution An applicable convention, is an assumption about when property is placed into service. It is used to determine when property depreciation begins. There are three types of conventions. The first, the “half-year convention,” assumes that all property placed into service, or disposed of, during a taxable year was placed into service, or disposed of, at the midpoint of that year. The second, the “mid-month convention,” assumes that all property placed into service, or disposed of, during any month was placed into service, or disposed of, at the midpoint of that month. The third, the “mid-quarter convention,” assumes that all property placed into service, or disposed of, during any quarter of a taxable year was placed into service, or disposed of, at the midpoint of that quarter. Half-Year Convention This convention applies to all depreciable tangible personal property. Exemptions: Residential rental and non residential real property Property subject to mid-quarter convention Mid-quarter convention If more than 40% of the total basis of property is placed in service during the last three months of the tax year, the mid-quarter convention applies. Exemptions: Property that is being depreciated under a method other than MACRS..

Does the Theory of Evolution include statements of lineages for the evolution of humans? Provide scientific rationale for inclusion/exclusion. Solution The theory of evolution does not describe the process for every single species.The process of evolution is based on the principle of development of all species from a common ancestor.The theory of evolution is based on the scientific views of many scientists and not just one .From Darwin\'s theory of evolution to the emerging ideas of scientists over the last 150 years, a lot of expansion has taken place regarding the evolution theory.In this context it can be said that we can always propose a hypothesis as to how humans evolved.The hypothesis proposed by us could be wrong as well but then it is a part of science.The current agreement regarding the evolution of humans is that as per the theory of evolution humans belongs to order Primates and Family Homonidae.It has been hypothesised from fossil records in the evolution theory that humans have evolved from primate ancestors in the late Mesozoic about 14 millions years ago and those ancestors no longer exist now.The modern humans have been reported to have evolved 200,000 years ago in east Africa..

Describe the prevailing arguments of what constitutes a \"just war,\" and assess the justice of the Vietnam War in that context. Speculate on how the world would be different today if the U.S. had not become involved in Vietnam. Solution What is a Just War? Six conditions must be satisfied for a war to be considered just: It was not a just war because it did not justified any of the criteria o fa just war: a) President Lyndon Johnson did not make a declaration of war like he was supposed to. It states that in the Constitution in order to be at war with a country a declaration of war has to be administered. President Johnson launched an air attack on North Vietnam while circumnavigating Congress. He did not ask for their permission to launch the attack that killed many Vietnamese citizens. Because of this in 1973, the year the war ended Congress enacted the War Powers Act which requires the president to receive permission from Congress before putting Americans in forces overseas. Things that were happening because of the war with North Vietnam were starting to affect the laws of the United States. This war made it clear that something needed to be changed. President Johnson used an airstrike that he thought was the best and only option to change the tide of the war. It went to America barely being in the war to America launching air strikes on North Vietnam. This escalated the war very quickly and made it clear that America was in the war. Along with the air strikes President Johnson also committed troops to the ground. This was extremely unnecessary and unjust considering The United States barely had their feet wet in the war. Because President Lyndon Johnson acted extremely quickly and didn\'t think things through it costed the Vietnamese their lives and even made Congress change the president. An air strike is obviously something that should be thought through because of all the consequences of it. When Congress changed the law it only reassured that the air strike was something that didn\'t need to be done. Although there were no laws against it at the time the President did not have legitimate authority to launch the air strikes. b) There were widespread massacres and bombings against innocents: It was stated by administration officials that the only reason for the bombing is because they thought it might encourage North Vietnam to accept South Vietnam as non communist. The President actually said one of the reasons for the bombing was to boost the confidence of South Vietnam and destroy the North’s ambition. By doing so it would create a need for the North to regroup with South Vietnam. There were many different attempts to try and level the playing field between Southern Vietnam and U.S. One of the ways was to slow the flow of North Vietnamese soldiers and supplies into South Vietnam by sending American forces to destroy Communist supply bases in Cambodia. These many efforts were made to end the war after this action. The U.S. made the .

Define relative refractory period Solution Relative refractory period is a phase of action potential.It is the time period during ehich a stronger than normal stimulus is required to bring about an action potential. Right after the action potential has moved down the axon,there is a time interval during which it is difficult for a neuron to send another signal,this time period is called relative refractory period.After the absolute refractory period,sodium chanels become to recover from inactivation and if during this time period a stronger stimuli is given it can cause the generation of an action potential.During relative refractory period continuous potassium ions flow out of the cell. Therefore sodium channel inactivation and higher than resting pk values are responsible for relative refractory period.

Describe how microorganisms can gain access to the nervous system Solution The brain has its own defence, protecting itself against any pathogenic invasions, I.e. The blood brain barrier (BBB) and the blood cerebrospinal fluid barrier (BCSFB). Also, the cells of the CNS can produce immune response against invading microorganisms. All of these pathogens I.e. Bacteria, fungi, amoeba and viruses are capable of reaching inside the CNS, most of these infections are lethal. Viruses infect the brain via axonal transport. Bacteria can transport via nasal mucosa into the brain. Eg: meningitis which is the inflammation of the meninges with symptoms having headache, fever, and neck stiffness. Bacterial meningitis occurs via the route of nasopharyngeal or middle ear colonisation, with microbial invasion of the tissue and intravascularspace, thus causing penetration of BBB and BCSFB. Bacteria commonly causing meningitis express antiphagocytic capsular polysaccharide , thus it allows their survival. Some bacteria also survive by gaining resistance to complement, and have the ability to survive within the phagocytes. Burkholderia pseudomallei, the causal agent of melioidosis, also known as encephalitis, occurs via causing cranial nerve palsies, coupled with peripheral motor weakness. Different organisms have different modes of entering within the brain, by either breaking the BBB and then surviving within the same by either forming capsules or somehow compromising the immune system ..

Briefly explain the rules of debits and credits as they relate to assets, liabilities, equity, revenue, and expenses. URGENT: NEED ANSWER ASAP PLEASE RESPOND WITH COPY AND PASTE, NOT ATTACHMENT USE ORIGINAL CONTENT NOT USED BEFORE ON CHEGG PLEASE ANSWER THROUGHLY TO ALL ANSWER TO BEST ABILITES ORIGINAL SOURCE NEVER USED BEFORE!!! Solution Answer: Before understanding the rules you should know that there are three kinds of Accounts/Ledgers namely: 1. Real Accounts: Include Tangible & Intangible Assets like Fixed Assets, Investment, Cash, etc [for ONLY ASSETS] 2. Personal Accounts: Include all Assets & Liabilities that are PERSONAL in nature like Accounts receivables/Payables, Banks, Owner, etc. [ for ASSETS, LIABILITIES & EQUITY] 3. Nominal Accounts: Include all income/gains and expenses/losses [for REVENUES & EXPENSES] NOW There are basically three main rules that are conceptually considered for debiting and crediting an account. 1. First rule is regarding Real Account [ONLY some ASSETS] The Rule says: Debit what comes in, Credit what goes out. so like if Cash is coming in, it is DEBITED. If Fixed Asset is sold( it is going) it is credited. 2. Second Rule is regarding Personal Account [Other Assets, Liabilities and Equity] The Rule says: Debit the receiver, Credit the Giver So when inventory is purchased on credit, Supplier becomes \'giver\', and hence Accounts payable is credited. 3. Third Rule is regarding Nomincal Account [Income/Gain and Losses/Expenses] The Rule says: Debit all expenses and losses, Credit all income and gains. Like when asset is sold at a profit, such profit is therefore CREDITED, likewise, Losses on sale are DEBITED. Also, every expense is always DEBITED, Revenues/Incomes are always CREDITED..
