Krafft-Ebing's book was so popular among both laymen and doctors that the terms "heterosexual" and "homosexual" became the most widely accepted terms for sexual orientation. Many modern style guides in the U. Gay especially refers to male homosexuality, [28] but may be used in a broader sense to refer to all LGBT people.

This allows students to focus on the process and techniques of investigation and the subsequent reporting. However, in Year 12 students are often given freedom to choose a topic or research question from the work covered over the whole of the course.

These "Open Inquiry" EEIs may provide more ownership, engagement and deeper understanding for the students but do place a bigger demand on resources and laboratory management. However, many teachers have found strategies to manage this should they choose to opt for a Open EEIs.

A Materials Requisition Form accompanies this document. My thanks to Biology teachers from Nanango for sharing this. Examples of Risk Assessment forms can be found in the tasks available on this page. A comprehensive form developed over several years by Urangan SHS can be found here: It is only an example and should not be assumed to necessarily meet the legal and safety obligations of any particular school or situation.

The method of artificial variation: The method of concomitant variation: This is also called a "correlation method". You can think that nature has manipulated the variables but it is still appropriate to class one as dependent and one as independent.

For example, do young leaves have the same density and distribution of stomata as older leaves; or how does temperature IV in a natural environment affect stoma opening DV?

Remember Me?

In this second case you do not need you to control the environmental temperature, but you do need to measure the DV at different temperatures.

The difficulty with the second approach is the control of other potentially influential variables such as humidity - as you have to take what you get. However, that does not preclude the variables in relationship being considered the IV and DV or being graphed as such. One way to address the confounding variables eg humidity is to collect data on the other variable as well.

You can run the statistics on each pair separately, but, for students who are not that "stats-savvy" then they could look for interactions between them at a visual level.

DEADLY EEI IDEAS

Although some micro-organisms are deliberately used to make foods such as yoghurt and cheese, other microbes 'spoil' food. Food, as well as meeting the nutritional requirements of humans, will also meet the nutritional needs of a vast range of micro-organisms.

These microbes will multiply rapidly in food, given the appropriate conditions such as temperature, pH and moisture.Flashcard Machine - create, study and share online flash cards My Flashcards; Flashcard Library; About; Contribute; Search; Help; Sign In; Create Account.

Biology also includes the study of evolutionary relationships among organisms and the diversity of life on Earth. It considers the biology of microorganisms, plants, and animals, for example, and it brings together the structural and functional relationships that underlie their day-to-day activities.

In chemistry, an ester is a chemical compound derived from an acid (organic or inorganic) in which at least one –OH (hydroxyl) group is replaced by an –O–alkyl group. Usually, esters are derived from a carboxylic acid and an alcohol. Glycerides, which are fatty acid esters of glycerol, are important esters in biology, being one of the main classes of lipids, and making up the bulk of.
