What type of gametes did Sutton predict? Mendel? (parental, recombinant, both) Solution 1. According to Mendel’s law of segregation : 2 . The Chromosomal Theory of Inheritance (Theodor Boveri and Walter Sutton --1903) was consistent with Mendel\'s laws and the basic postulates were: -----------------------These lead to the conclusion that both Sutton and Mendel predicted parental types of gametes because in case of parental type , gametes are produced in equal proportion but recombinant type produces gametes in unequal proportions. Besides this , In 1911, after observing that linked traits could on occasion be inherited separately, Thomas Hunt Morgan suggested that \"crossovers\" can occur between linked genes and crossover is the prime reason for recombination.

With reference to Barth (2014), discuss how the author assessed the extent to which unmodified historical cost, modified historical cost, and fair value measurement possess the qualitative characteristics specified in the IFRS Conceptual Framework. Solution The conceptual framework in IFRS states the qualitative characteristics of the financial statements to be useful which are as follows: 1. Fundamental : Fundamental qualitative characteristics are relevance and faithful representation. 2. Enhancing: Enhancing qualitative characteristics are comparability, completeness, verifiablity and understandability. According to Barth(2014), Historical cost does not possess the qualitative characteristics of the IFRS conceptual framework as it does not facilitates comparability and relevance but yes it is sometimes relevant. The historical cost should be modified to use in financial statements, it should be indexed for Inflation. Modified historical cost possess the qualitative characteristics of the IFRS. It is understandable, complete, accurate, but not considered as faithful representation. This is widely used but both modified historical cost and unmodified historical cost lack meaning. Whereas the Fair value presentation is more consistent with the new framework and hence it should be widely used. This paper concludes that assets and liabilities at large should be measured at fair value to provide the financial statements with the qualitative characteristics..

This kind of data is an example of: 2. In the video \"How Does Evolution Really Work?\", biologists described an example where the length of individual hummingbird beaks grew longer in response to changes in their food source (flowers). True False 3 The observation that the individuals possessing favorable traits are more likely to survive and reproduce than those possessing less favorable traits is the basis for: 4.

Due to ___________________, \"bad science” (e.g. fake data or fake results) is eventually discovered and revealed. powerful police forces 7. Darwin\'s Hypothesis of Evolution by Natural Selection included the observation that populations often grow faster than the food supply and therefore individuals need to compete for resources. Darwin borrowed this idea from the work of: 8. Lamarck\'s \"Inheritance of Acquired Characteristics\" can best be described as: disease and starvation are required to keep population size in check 9. Aristotle and other early philosophers believed that species were \"immutable\" or \"fixed\", which means: species are always changing species don\'t change over timeA.taxonomy B.artificial selectionC.empirical evidenceD.non-factual informationE.a belief Solution 1)B)Artificial Selection as it tells about the way birds survive and their mating. 2)True yes it is rightly stated. 3)D)Natural selection which says traits move from one generation to other. and the ones with more traits survive more than other here. 4)E)it must deal with evidence that is empirical (i.e. the kind that can be observed).

Write an algorithm that reads a list of integers from the keyboard, creates a list of them using linked list implementation, and prints the result Solution /* Algorithm: Implementation of linked list. Create a node type class which will hold an integer and next pointer to point to another node. Create a constructor which will construct an object of type node with the integer type data as the only parameter and initializing next pointer to NULL. Create LinkedList class which will only have head pointer. Create a constructor which will initialize this head pointer to NULL. Create a append method which will recieve an input of type integer from the user and append it to LinkedList using below steps: 1.Create a Node type object. 1.IF head is NULL assign a Node type object created in 1st step. 2.IF head is not NULL then traverse to the end of the linked list till you found a Node which has next pointer set to NULL. 3.Add Node type object created in first step to the next pointer of last node. Create a print method which will traverse the list from the head of the linked list to the last node(Node with next pointer NULL) and while traversing it will keep printing the node data.

Which of the following is a way in which meiosis differs from mitosis? In meiosis, a spindle of microtubules does not form. Meiosis produces only diploid daughter cells. Meiosis is found in asexual reproduction. In meiosis, the parent cell divides twice. Meiosis never produces gametes (sex cells). Question Part Solution Answer is 4 In meiosis parent cell divides twice whereas in mitosis parent cell divides only once. Meiosis is a reductional division which occurs in diploid cell to produce four tabloid cells whereas mitosis is a educational division which either occur in haploid or diploid cell to produce haploid or diploid daughter cells. Meiosis produces balloon gametes. Also, meiosis is not found in asexual reproduction. Meiosis and mitosis both involves formation of spindle of microtubules..

Phase contrast 4. Scanning (SEM) 5. Transmission (TEM) Solution The characteristics of each microscope is as follows: 1.COMPOUND MICROSCOPE In compound microscope the objective lens forms a real, inverted and magnified image of the object. The eye piece acts like a magnifying glass and forms a virtual erect and magnified image. Object is placed outside the principal focus of the objective lens. It consists of two convex lens, ocular, close to the eye and s3cond objective lens. It also reduces chromatic abberrations. 2. STEREO (DISSECTING) It is an optical microscope which is designed for low magnification, it uses light reflected from the surfacevof an object rather than transmitted through it. It forms three dimensional erect image as the prism under the eye piece reverses the image. 3. PHASE CONTRAST It is used to examine biological tissues (live microorganisms). It is a type of light microscopy that increases contrasts of transparent and colourless objects. This is achieved by influencing the optical path of the light. Thus contrast of light and dark makes the specimen visible to the human eye. 4. SCANNING (SEM). It is used for producing high resolution images of a sample surface. The images have 3-D appearance and best used to judge the surface structure of the sample. It produces image using focused beam of electrons. In SEM, the picture is shown on the monitor. 5.TRANSMISSION (TEM). It is based on transmitted electrons. It provides details of internal composition (show morphology, crystallisation, stress or even magnetic domains of the sample). In TEM, picture is shown on fluorescent screens. It provides 2-D picture of the sample. It uses electromagnetic lenses to focus the electrons into very thin beams..

The zygomycota produce... septate hyphae with solid septate coenocytic hyphae asexual spores that are the most desiccation-resistant stage of the life cycle multi-nuleate zygosporangia zygosporangia that are produced asexually two different types of spores: one through asexual processes and one through sexual processes septate hyphae with a central pore Solution Zygomycotina contain about 1050 species of fungi. These fungi live in soil as saprophytes or parasites on plants, insects and samll animals. The hyphae are coenocytic or multinucleate. The hyphae are not septate but sepat are formed at the site of formation of gametangia. The zygophores are produced during sexual reproduction and form zygosporangia by fusion of (+) and (-) hyphae. Asexual spores formed include mitospores and chlamydospores. These spores are dormant and desiccation resistant. Options 2, 3 and 6 are correct..

Political attitudes were found to be most conservative in the age-60 group and least conservative in the age-20 group. What type of method was used in this study? Can you conclude that people become more politically conservative as they get older? Why or why not? Propose alternative ways of studying this topic. Solution This is an observational study. If it is an experimental design, we need to perform Chi-square test, odds ratio, or one way ANOVA. Or simply, if the data is available for each age group, the coefficient of variation is used to determine which age group is conservative..
