Biology – Preliminary – Evolution of Australian Biota 1. Evidence for the rearrangement of crustal plates and continental drift indicates that Australia was once part of an ancient super continent identify and describe evidence that supports the assertion that Australia was once part of a landmass called Gondwana‚ including: ▪ − matching continental margins ▪ − position of mid-ocean ridges ▪ − spreading zones between continental plates ▪ − fossils in common on Gondwanan continents

Half of these people‚ living in Sub-Saharan Africa‚ survive on below $2.00 a day. On the other hand‚ the income inequality that arrived with the advent of the industrial revolution has been steadily increasing in most developing and developed nations (UN‚ 2016). While it is tempting to think that the two completely correlate with each other‚ Dr. Sachs argues otherwise. Poverty in places like Sub-Saharan Africa is‚ he says‚ not because of rising income inequality

The Judicial branches are separated into three departments or branches and are disclosed to separate bodies of magistracy. The branches are divided in three‚ which are legislature‚ executive‚ and judicial system. The most powerful among the three branches of government in Texas is the legislature. Though‚ none of the three branches are particularly strong. When described what branch is the strongest than others‚ the legislature branch is described as the strongest. Conversely‚ just like the other

Giraffe are browsers and mainly eat buds on trees‚ shrubs and leaves They also eat herbs‚ climbers and vines‚ and prefer flowers and fruit when in season Acacia leaves and shoots form the bulk of a giraffe’s diet in most areas. Giraffes have more than one stomach Giraffes are ruminant Giraffes have four stomachs and the

enzyme-catalyzed reaction is called a substrate. The area of the enzyme that binds to the substrate is called the active site - where the action takes place. * Cofactors and coenzymes are small molecules or ions that help enzymes to act. HSC Biology Notes – Hugh Phillips Maintaining a Balance 1.Most organisms are active in a limited temperature range: Identify the role of enzymes in metabolism‚ describe their chemical composition and use a simple model to describe their specificity on substrates:

Michelle Gordon‚ TJ (Group 4) Section 33 Yeast Cell Respiration 10/04/2010 Part B: Explanation of Results All cells carry out the process of cell respiration in order to meet their energy needs. It is advantageous for cells to have the ability to metabolize different substrates. In this experiment‚ we investigated each sugar’s (glucose‚ lactose‚ sucrose‚ fructose‚ and lactose/lactaid) cell respiration rate. When referring to my group’s graph and data‚ glucose ended up with the highest

Title: Grass Growth Effect Jessica Suarez Option A: Observation: During the winter‚ you spread salt daily on your driveway to melt the snow. In the springtime‚ when the lawn begins to grow‚ you notice that there is no grass growing for about 3 inches from the driveway. Furthermore‚ the grass seems to be growing more slowly up to about 1 foot from the driveway. Question: Might grass growth be inhibited by salt? My hypothesis is that the grass growth in being inhibited by salt. A typical

Essay Question 1 Explain how changes in habitat can lead to habitat fragmentation. How does this affect the population of animals in that area? Species lose their habitats when those habitats are destroyed outright‚ but habitat loss also occurs when habitats are altered through more subtle processes‚ including fragmentation and other forms of degradation. The sudden and complete elimination of habitat is uncommon at large scales; instead‚ what we usually witness is gradual‚ piecemeal degradation

Photosynthesis - The process by which an organism uses the energy from the sun to produce its own food C. Autotrophs - Organisms that are able to produce their own food D.
