1.1-Compare and contrast the roles of the teacher and teaching assistant in assessment of learners achievements. Both the teachers and the teaching assistant main role is to monitor and assess pupils achievemnets in the class‚ but the main teacher has overall responsibility for recording and making the decisions that may be needed for example moving a child into a different group to match their ability levels. The teacher needs to be aware of the progression made by all the children in their class

are segments of DNA that code for proteins or RNA molecules. These genes are the genetic material that is passed down from generation to generation in all species. The individual DNA segments each individual carries are known as their alleles or genotype. When two alleles are identical they are homozygous and when they are different they are heterozygous. These alleles are expressed physically through what is known as the phenotype. An example of a phenotype of a gene is hair color‚ which may be

The Different Roles of Macromolecules in Biology.There are four types of macromolecules that I am going to describe: Proteins‚ carbohydrates‚ lipids and nucleic acid. I will also describe the functions and why they are important in our bodies. Proteins Proteins are polymers of amino acids that are joined head-to-tail in a long chain that is then folded into a three-dimensional structure unique to each type of protein. The covalent linkage between two adjacent amino acids in a protein (or polypeptide)

Currently‚ 4.5 million people in the United States approximately have Alzheimer’s disease. (Burns) Alzheimer’s disease presents the victim with a sharp decline in memory‚ language‚ visuospatial perception‚ executive functioning and decision-making. Because this disease is so harsh on

E) An organism that is homozygous for many recessive traits is at a disadvantage. 2) How many unique gametes could be produced through independent assortment by an individual with the genotype AaBbCCDdEE? Write down the gametes 3) Why did Mendel continue some of his experiments to the F2 or F3 generation? A) to obtain a larger number of offspring on which to base statistics B) to observe whether or not a recessive trait would reappear

Chapter 22 Descent with Modification: Darwinian View of Life Overview: Darwin Introduces a Revolutionary Theory On November 24‚ 1859‚ Charles Darwin published On the Origin of Species by Means of Natural Selection. Darwin’s book drew a cohesive picture of life by connecting what had once seemed a bewildering array of unrelated facts. Darwin made two major points in The Origin of Species: I. Today’s organisms descended from ancestral species that were different from modern species. II. Natural

mathematical equation created to predict genotype and phenotype frequencies in a population that is not experiencing any selective pressure‚ if model fails evolution must be occurring - Under Mendel’s model‚ the two alleles can be represented by... p + q = 1 (100% of the alleles in the population) where p is the dominant allele and q is the recessive allele - The genotypes can be represented by the equation (p+q)² = p² + 2pq + q² = 1 (100% of the genotypes in a population) where p² is homozygous dominant
