pleiotropy polygenic inheritance is a non-Mendelian form of inheritance in which a particular trait is produced by the interaction of many genes. Polygenic inheritance refers to the kind of inheritance in which the trait is produced from the cumulative effects of many genes in contrast to monogenic inheritancewherein the trait results from the expression of one gene (or one gene pair). In humans‚ height‚ weight‚ and skin color are examples of polygenic inheritance‚ which does not follow a Mendelian pattern

group MRSA also did the same practical but they used pH 2. The results that they obtained were that there were 45 cells present on the petri dish after five days. MRSA also obtained a value of 36000000 per litre. Bacteria grow by binary fission and yeast grows by budding but the patterns of growth for a population are the same. There are many phases of microbial growth. These are lag phase which is when the microbe starts

flow will occur and the resistance to flow will be independent of the pipe wall roughness (e). Meanwhile‚ turbulent flow occurs when the value of Reynolds number is exceeding 4000. For large viscous force‚ whereby Re value is less than 2300‚ viscous effects are great enough to damp any disturbance in the flow and the flow remains laminar. The flow is called laminar because the flow takes place in layers. Any combination of low velocity‚ small

Transpiration Formal Lab Report By Jessica Tran Introduction When water is transported from the roots to the mesophyll cells in the leaves‚ it is evaporates out the stomates‚ called transpiration‚ to create a lower osmotic potential. Osmotic potential is the part of the water potential of a tissue that results from the presence of solute particles. Even though the stomates open to release water‚ it also brings in carbon dioxide to produce sugar and oxygen through a process of photosynthesis

Determining the Effect of Light Intensity on Photosynthesis Avalon Pernell‚ et al Abstract: The purpose of this lab was to determine how light affected photosynthesis‚ specifically the production of O2 bubbles. It was predicted that when the light was more intense the O2 bubble production will be high. Conversely‚ when the light was less intense the O2 bubble production will be lower. Basically the plant that is closer to the light will produce more bubbles than the plant that is placed farther away

Planning Aim In this experiment I will be testing the effect of temperature on the plasma membrane of a beetroot. I will do this by measuring the percentage light transmission using a spectrophotometer. Once I have obtained my results‚ I will justify them using scientific knowledge explaining what I have observed whilst carrying out the experiment. Factors to be controlled "« The pH concentration "« Regular use of distilled water "« Ensuring that the surface area of each piece of beetroot is

figure 2. In figure 1‚ we can see that none of the plants were able to photosynthesize. Respiration rates happen during the night when there is no sun or light to fuel the plants energy source. We can also see that the blue light didn’t do to well and started conserving it’s energy and oxygen. In figure 3‚ we get the gross data which is the sum of the absolute value of photosynthesis in the light and respiration in the dark. We are able to see that the white light did far better than the

The Effects of Individuals’ Detection of Changes in Images on Reaction Time Abstract The purpose of this current study was to examine how individuals detected or noticed change when viewing images on their level of attentiveness. The experiment consisted of 22 participants who had to detect change across conditions for 20 minutes. These conditions were importance of change (marginal and central) and change type (color‚ location and disappearance and reappearance of images). These

Thermodynamics- Enthalpy of Reaction and Hess’s Law December 5‚ 2011 Kylie Case‚ Emma McKee‚ Rebecca Smith Purpose: In this lab‚ the purpose was to verify Hess’s Law. Theory: Four main topics were covered during this experiment including enthalpy of reaction‚ heat of formation‚ Hess’s Law‚ and calorimetry. The first being enthalpy of reaction‚ ΔHrxn‚ which is the heat or enthalpy change for a chemical reaction. The energy change is equal to the amount of heat transferred at a constant

CO2 Lab Report Intro Alka-Seltzer tablets are used to treat cold/flu symptoms as it produces CO2 when dissolved in water. The goal of this lab is to calculate the amount of NaHCO3 is needed to produce enough CO2 gas to fill the room. Experimental One Alka-Seltzer tablet was weighed on the analytical balance. Then a piece was measured out to be between 0.21 and 0.28 grams. 500mL of distilled water was added to a 600mL beaker. 80mL of water was mixed with 20mL of 6M HCl in a 150mL beaker. A
