Women’s Brains Summary
Women’s Brains by Stephen Jay Gould discusses how inferior women are to men, based on scientific data. George Eliot, in the prelude of Middlemarch, grieved over the unfulfilled lives of talented women. She wrote in 1872 that the leaders of European anthropometry or measurement of the human body, scientifically measured the inferiority of women. But it was craniometry or measurement of the skull, led by Professor Paul Broca, which got more attention. Broca argued that women had smaller brains than…...

Transpiration Lab
When water is transported from the roots to the mesosphere cells in the leaves, it is evaporates out the stomata, 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 stomata open to release water, it also brings in carbon dioxide to produce sugar and oxygen through a process of photosynthesis. The water absorbed by the roots is moved…...

Human Traits Lab
There are two types of genes, the dominant and the recessive genes. The dominants, often represented by a capital letter, are that when present, the living thing will have the characteristic. Recessive genes, represented by a lower case letter can be together with a dominant gene or another recessive gene. For example: suppose that in bees, the shape of their body is dominant when shaped as a cone (S), and recessive when shaped as a sphere (s). In this case…...

Digestion Of Starch By Salivary Amylase
The role of salivary amylase in the digestion of starches remains controversial. In the absence of pancreatic amylase, the key enzyme for starch digestion, salivary amylase may well represent a potential compensatory alternate pathway for the digestion of amylose, amylopectin, and glycogen. Clinically significant depression of pancreatic amylase occurs in chronic pancreatitis, pancreatic resection, pancreatic neoplasm, cystic fibrosis, and other causes of pancreatic insufficiency. Quantitation of salivary amylase in these diseases has yet to be performed. It is also unclear…...

The misinformation effect is a memory bias that occurs when misinformation influences people’s reports of their own memory; this reveals the pliability of memory. There is a general acceptance, supported by research, for the misinformation effect: The introduction of misleading post event information will impair the memory of an original event (Toland, Hoffman & Loftus, 1991). In exploring the factors that enhance susceptibility to misinformation, it was discovered that allowing time to pass after the event, so that the original…...

Temperature affects the fermentation of the yeast
The chemical reactions within yeast are facilitated by enzymes; most enzymes optimal temperature range is warm. The warmer the water, the more the enzymes are in their optimal temperature angle and the more efficiently they catalyst chemical reaction; this makes the fermentation proceed more quickly. In this experiment, the effect of variation of temperature on the fermentation of yeast was tested. If temperature affects the fermentation of the yeast, then the rate of yeast fermentation will change with the different…...
