It also showed the yeast respires at its lowest rate with sorbose and maltose was in between the rate of yeast respiration of glucose and maltose. Introduction In this investigation we are going to investigate the amount of respiration by how much carbon dioxide is produced‚ and how using sorbose‚ glucose and maltose sugar types affects rate of respiration.

Light and nutrients. Light is the key abiotic factor which controls the growth of woodland. It controls the spacing of the trees‚ shape of the trees and the shape and structure of the shrub and ground layers. If a trees branch does not receive enough light it will die. Irelands native woodlands are deciduous so there is a dramatic variation of the amount of light which reaches the forest floor through the seasons. In spring when the leaves have yet to grow and the temperature has begun to rise the

Reliability and validity are key concepts in the process of selecting among job applicants‚ since the main goal of selection is to make accurate predictions about which individuals will perform well on the job. Reliability is the consistency of measurement‚ or the degree to which an instrument measures the same way each time it is used under the same condition with the same subjects (definition from: www.technetium.cen.brad.ac.uk). For example if the applicants are given different selection tests it would

purpose of the study. To ensure that this was achieved‚ the survey needed to demonstrate validity and reliability. Validity‚ as described by Heale and Twycross (2015‚ 66)‚ examines whether the specific concept has been accurately measured. In contrast‚ according to Floss (2013‚1)‚ reliability refers to the consistency of the instrument to measure the concept. The instrument needed to feature external validity in order for the data collected to be generalised (Heale and Twycross 2015‚ 66). To ensure
