permeability of the cell membrane: The question being answered from doing this experiment is ‘How do different temperatures affect the permeability of the plasma membrane of beetroot?’ Beetroot contains red pigments called betalains‚ located within the cell vacuole. Normally the pigments cannot pass through membranes but they leak out when the beetroot is cooked or placed in alcohol. The aim of this practical is to use beetroot to examine the effect of temperature on cell membranes and relate the effects

a) Explain Aristotle’s theory of four causes (25 marks) Aristotle’s interest in explaining why things exist as they do led to his theory of Four Causes. He rejected Plato’s theory of Forms and was more intrigued by the particular form in which an object took‚ as opposed to the ‘ideal‚ perfect’ form.

Although many of us studying behavior want to accept the hypothesis; taking vitamins causes crime‚ there are many possible factors we need to consider before confirming the hypothesis to be true. By avoiding the “correlation versus causation fallacy‚” illustrated in the textbook‚ the newspaper article lacks sufficient evidence to conclude vitamins as a cause to the increase in crime reports. By conducting an experimental design‚ researchers can test if there’s any correlation between the two variables

increase in cystolic calcium concentration causes contraction in myocardium. Calcium from the extracellular fluid enters the cardiomyocyte through the L-type Ca2+ channels after being propagated by the cardiac action potential which depolarises the cell. This flood of calcium triggers more calcium release from the sarcoplasmic reticulum via Calcium-Induced Calcium Release (CICR). Calcium binds to the ryanodine receptor on the sarcoplasmic reticulum which then causes vast release of more calcium. This calcium

Why add two years? This is the question everybody is asking. “We need to add two years to our basic education. Those who can afford pay up to fourteen years of schooling before university. Thus‚ their children are getting into the best universities and the best job after graduation. I want at least 12 years for our public school children to give them an even chance at succeeding. ”President Benigno S. Aquino” These are the words that really made a great impact to me.
