    The dry wallum is a harsh environment that is battered by the sun and wind every day and with a base of porous sand; water availability is very scarce and must be conserved. The abiotic factors in the dry wallum are that the area is exposed to high amounts of sunlight which causes a loss of water in the leaves through transpiration. Since the wallum is so dry and hot; bush fires play a major cycle in the dry wallum which the trees have adapted to cope with. The roots of the plant and tree species have to cope with the leeching of nutrients because of the high porosity sand in the dry wallum.…

    Yes there was a change because with the starting snail population there was a great variation from 1-7. After the crab began eating only the snails with the thickest shells survived. The snails with the thinnest shells were eaten by the crab. Only snails with shell thickness 4-7 were left after the crab had their meal. The original snails with thickness 1-3 were eliminated from the population by the crab. The crab will usually try to expend as little enrgy as it can to maximaize its happiness so the snails with thinner shells will likely be targeted first and eventually eliminated.…

    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…

    Gas exchange is a biological process that is essential for the survival of an organism. The purpose of this process is to obtain oxygen from the environment (which is necessary for cellular respiration, and to dispose of CO2, a bi product of respiration. An efficient gas exchange system has 3 requirements. It must have a large surface area over which the gases can diffuse. A large surface area maximises the amount of area available for the gases to exchange. It must also be moist. Oxygen must first dissolve into a fluid before it can diffuse into a cell. Having a moist gas exchange surface ensures the gases can be dissolved. Thirdly, the membrane through which gases diffuse must be thin. Gas exchange is driven by concentration gradients. Diffusion is the process which moves the gases. The rate of diffusion is determined by the concentration gradient and the distance so having a smaller distance for the gases to travel increases the rate at which gas exchange can occur. A thick membrane would mean a slower rate if diffusion because the gases have to travel further. In this essay I will discuss the diversity in structure and function of gas exchange systems of three animal groups, Insects, fish and mammals. I will also discuss how these gas exchange systems have allowed each animal group to be successful in their environment.…
