The end of unit test in Genetics will be on Monday (10TM) or Tuesday (10BC). Work through the tutorials at your own pace stopping the video to answer questions before moving on to view the correct answers Make sure that you ask about any difficulties you experience during your study. You will need to prepare thoroughly to achieve the best result. This topic contains a lot of material.
We have used a lot of terms in the study of ecology. Watch the short video on niche and communities then read over the glossary of other terms. Try the test at the end. Chose a word from a list beside each question that best fits the description.
Brief glossary of other terms you have met:
Communities: all organisms found in a particular area
Ecology:The study of relationships between organisms
Herbivores: Eat plants only
Adaptations: features of a species which enable members to survive and produce offspring
Carnivores: eat animals only
Decomposers. Organisms such as bacteria which break down dead bodies of other organisms
Parasites: Feed off living organisms
Ecosystems; Study of interactions between the community and the physical environment. Focus on energy flow
Population: The study of groups of organisms belonging to the same species, e.g.the brown crabs in the mangroves at Rutherford
Consumers: Eat other organisms
Environment: Factors which can affect a species, physical and biotic.
Year 10, writing fully balanced chemical equations homework
A whole lot of the chemistry you have studied this year comes together in this exercise.
ions and how they are formed.
naming ionic compounds and writing their formula
…….. and finally the last piece in the jigsaw writing a fully balanced chemical equation.
If you study NCEA chemistry at level 1 next year a rough guide is
Achievement: writing word equations.
Merit: Inserting chemical formulae into an equation.
Excellence: producing a fully balanced chemical equation.
Revise what we did today by watching the video then do the short exercise. In your notebook write down the word equation and complete it (achievement) Underneath the word equation insert the chemical formula of each substance (merit). Finally balance the equation (excellence) NOTE this usually involves sticking 2 in front of something
