Mariella Hines is a 9 year-old African-American girl attending the 3rd grade in the JFK School. She was referred to the School Psychologist because she has recently become very withdrawn during class, refusing to speak to anyone, including her teacher and peers. Previously she seemed to have age-appropriate social skills, interacting well at school. Her withdrawal started suddenly. Mariella’s teacher, Mrs. Levine, called Mariella’s mother to find out more information, but her mother said that Mariella seems fine at home.…
6. Briefly describe the two meiotic events that contribute to genetic diversity in a population. Each gamete (sex cell) is unique due to a process during meiosis called cross-over which (simplified) swaps around some genes to create unique chromosome combinations. meiosis helps to create a population that is not only physically and genetically different but also one, which is perfectly fit to survive.…

Both of these show the distribution of phenotypes. In directional selection, the distribution of phenotypes forms a "bell curve." Selection against one of the extreme phenotypes causes the distribution to move in one direction or the other. An example might be plants whose flower color is determined by incomplete dominance: white, pink, or red. Pink flowers may be the average phenotype, but if we start to remove red flowers from the population, the "mean" phenotype will be shifted toward white flowers.…

I think that free earlobes is the dominant trait (Because none of the 20 people I surveyed had attached earlobes). I think that no hair on knuckles is the dominant trait (Because 75% of the people I that surveyed had it). I think that straight hair line is the dominant trait ( Because 75% of the people I that surveyed had it). I don't know whether straight hair or curly hair is the dominant trait (Because it was an even split). I think that no cleft chin is the dominant trait (Because 90% of the people I surveyed had it). I don't seem to exhibit any of the recessive traits shown here. I shared the same chin shape, earlobes and amount of hair on knuckles. I didn't exhibit any trait that was not exhibited in my parents. If an offspring exhibited a recessive trait that neither parent exhibited, it would mean that both parents carried it. I was surprised that none of the 20 people had attatched earlobes. Yes, It is possible that a recessive trait…

LAB 4: KIRCHHOFF’S RULES DIY Lab This section is adapted from reference 1. Objective In this experiment, you will experimentally verify Kirchhoff’s rules by measurement and by mathematical analysis. Apparatus (Lab Kit* or NIC Lab) 5 resistors one 6V battery or power supply (each under 1.5 kΩ each, not all equal) digital multimeter 12 connecting wires *If you do not have the Lab Kit, you can use equivalent items. Contact your instructor regarding equivalent items to ensure that the objective of this experiment is maintained. Introduction The most basic of electrical circuits contains a single resistor connected to the terminals of a battery. This is a complete circuit, forming a continuous path between the battery terminals. The resistor is called the load and the battery is the source of emf. We assume that all wires used as connectors are ideal, with Rwire 0 . In analyzing a circuit, we make use of a representation of the circuit termed a schematic. You are already familiar, after experiment the Basic Electric Circuits Lab, with the representation of resistors and batteries; the only new symbol we introduce is that of the node, shown in Figure 4.1 below. It is simply a point where the current divides or joins. We are now ready to analyze circuits. To analyze a circuit we do two things: 1. find the current in each component, and 2. find the potential difference across each component. The rules of circuit analysis are called Kirchhoff’s rules. The Loop Rule This rule asserts that the net change in electric potential around any closed loop in a circuit is zero. This is a statement of energy conservation, since a charge that moves around any closed DIY First-Year Physics Laboratory …
