Compare and contrast essays are a common type of academic writing in which a student is asked to identify and analyze the similarities and differences between two or more subjects. These types of essays can be used to examine a wide range of topics, from historical events and political ideologies to scientific concepts and artistic movements. Some possible compare and contrast topics might include:
Political systems: This could include comparing and contrasting different forms of government, such as democracy and autocracy, or different political ideologies, such as conservatism and liberalism.
Historical events: Students could compare and contrast major events in history, such as the American Revolution and the French Revolution, or the world wars of the 20th century.
Scientific concepts: Students could compare and contrast different scientific theories or discoveries, such as the theories of evolution and intelligent design, or the laws of thermodynamics and gravity.
Artistic movements: Students could compare and contrast different artistic styles or movements, such as impressionism and expressionism in painting, or classical and romantic music.
Technology: Students could compare and contrast different technological innovations, such as the personal computer and the smartphone, or online and traditional education.
Regardless of the specific topic being addressed, a compare and contrast essay should begin with a clear introduction that identifies the two subjects being compared and the purpose of the comparison. The body of the essay should then present a series of points of comparison and contrast, using specific examples to support each point. Finally, the essay should conclude with a summary of the main points of comparison and contrast and a discussion of the implications or significance of those differences.
Chapter 14: Mendel and the Gene Idea Flashcards
Answer: Yes, variations that confer an advantage to an individual organism are inherited. Which of the terms correctly describes this type of mutation? E Alexis inherited the hemophilia gene from Nicholas II. One of two alleles from each parent is randomly transmitted to offspring. Out of 3 tall plants one would be pure homozygous tall TT and two would be heterozygous tall Tt. B each daughter cell receives exactly half the genetic information in the parent cell. A Neither of the parental genes is dominant over the other.
Independent assortment of alleles for height during meiosis can produce offspring with varying degrees of height at maturity. Very Long Answer Questions 5 Marks 1. Flower color and seed color assort independently. Females can be black X+X+ , orange XOXO or a mixture of orange and black called tortoiseshell X+XO. This suggests that the genetic make-up of the tall parent can be depicted as a TTWW b TTww c TtWW d TtWw Answer: c Genetic make-up of tall plant can be depicted by TtWW.
NCERT Solutions for Class 10 Science Chapter 9 Heredity and Evolution
What is the genotype of the yellow-seeded parent? Will geographical isolation be a major factor in the speciation of a self- pollinating plant species? Black color results from an independently assorting allele B that is dominant over an allele for gray b. A DNA strand of E. Answer: The variations provide stability to the population of various species by preventing them from getting wiped out during adverse conditions. A person who is heterozygous for long ear lobes mates with a person who is homozygous for normal ear lobes. Only variations that confer an advantage to an individual organism will survive in a population. The predicted outcome of the F2 is diagrammed in the Punnett square shown in the figure, where 1, 2, 3, and 4 represent the genotypes corresponding to each box within the square.
MCQ Questions for Class 10 Science Heredity and Evolution with Answers
Both: - Mutations can be caused by an alteration in the DNA sequence. B Sickled cells help prevent vitamin A deficiency among African populations. Is this information enough to tell you which of the traits — blood group A or O is dominant? Determine the probability that their offspring will have small fingers. Multiple genes control the behavioral pattern of an individual. The mutation observed with the loss of object X can either be guanine or adenine. If black colour is dominant out of every 4 dogs, 3 will be black and if white colour is dominant 3 out of 4 dogs will be white. When Mendel crossed heterozygotes for flower color and seed color, what proportion of the offspring had both dominant phenotypes? Maria's maternal uncle suggested that Maria create a pedigree to track the disease in her family.
A form of intermediate inheritance in which one allele for a specific trait is not completely expressed over its paired allele. Given the sequence shown, what would NOT be the resulting DNA strand once replicated? If you have any query regarding CBSE Class 10 Science Chapter 9 Heredity and Evolution Multiple Choice Questions with Answers, drop a comment below and we will get back to you at the earliest. Match the most likely genotypes for each relative in his family below. Recessive alleles typically encode nonfunctional proteins. Answer: No, because different designs are the product of evolution and different species have different body design to suit or adapt to their environment. Determine the gene order of the chromosome by placing each gene on the outside of the circular chromosome map. They have the same genotype and phenotype.
Gregor Mendel: dominance :: DNA from the Beginning
Human diseases like cystic fibrosis show similar patterns of inheritance as that of Mendel's garden peas. The dominant allele refers to the allele, which shows the physical expression visible on the human body because of its dominance. The sugar below it has purine labeled 'Y' attached. Now, you might wonder how something like that is possible. Thus, sex is determined at the time of fertilisation. Purple flowers are dominant to white flowers.
Each is controlled by an independently assorting gene and has dominant and recessive expression. Select the incorrect statement. During meiosis, the behavior of homologous chromosomes can contribute to the separation of the alleles into distinct gametes for each genetic locus. D The child has one more chromosome than either of the parents. PART 1: Which statement explains the results of this cross? In a single individual variety, the desired characteristics carried in different combinations can be coupled and maintained.
C Prokaryotic chromosomes are not contained in a membrane-bound organelle. It is likely to have arisen earlier and has now spread to 60% of the population. C Feed the patients the missing enzymes in a regular cycle, such as twice per week. C They are found only in embryos and in the bone marrow of adults. Beneficial mutations: - A mutation confers antibiotic resistance in bacteria. They cannot revert to wild type.
