I personally selected a maroon clownfish with two anemones. I also chose 5 sergeant majors‚ 2 bleenies and a yellow tang. 2. What changes did you make to your reef tank during the 12 weeks and why did you make them? After I selected my fish‚ I noticed that the tank

Investigating Effects of duration of heating on permeability of beetroot cell membrane Introduction: Cell membranes contain many different types of molecules which have different roles in the overall structure of the membrane. Phospholipids form a bilayer‚ which is the basic structure of the membrane. Their non-polar tails form a barrier to most water soluble substances. Membrane proteins serves as channels for transport of metabolites‚ some act as enzymes or carriers‚ while some are receptors

Interphase: DNA has formed already‚ but it remains in the simple form of chromatin. Chromatins are structures that are loosely coiled in the cell.3 I also observed during my lab that this was the only stage where I could still see a nucleus and nucleolus intact within the cell; this is because it’s the only stage where the nuclear membrane has

is a known stimulant increasing blood pressure‚ heart rate‚ and myocardial contractility by activating the release of catecholamine by binding to nicotinic acetylcholine receptors on the adrenal medulla and postganglionic sympathetic nervous system [1]. Several possibilities may help explain this aberration. For one‚ the sample size may simply have been too small to accurately determine the effects of nicotine on heart rate. This possibility is supported by the experimental data of a larger sample

In Lab 8‚ we had analyzed remains found at a wooded area near Jonesburg and tried to determine if the bones belonged to a 28-year-old woman who had been reported missing from a city within the vicinity. Upon analysis‚ it was determined that they did belong to a female. However‚ it was not possible to determine if the bones did belong to the missing women. Lab 12 presented the opportunity to genetically analyze the remains found. DNA profiling‚ also referred to as typing and fingerprinting‚ uses genetic

the presence of sugar at room temperature or in an incubator? | -Observing Cellular respiration in yeast cells. | Yeast Lab Background Information: Yeast is a tiny unicellular fungus that obtains energy from outside sources (a heterotroph) mostly sugars in order to grow and reproduce. Yeast is often used in bread dough to make the dough rise. With the presence of oxygen a yeast cell creates energy by performing cellular respiration and producing a high amount of ATP‚ but when in bread
