All of the plants in the groups with 5 seeds at least grew. This indicates that dependent variables such as competition and the environment itself has an influence on how a plant grows and develops. If the T-Stat>T-Critical‚ then we reject the null hypothesis and choose the alternative. The only one we actually accept the null hypothesis are the Leaves

The Red Queen Hypothesis The Red Queen Hypothesis was formulated by Van Valen in 1973‚ and its original purpose was to give an understanding of the adaptation dynamics between species (Vermeij and Roopnarine‚ 2013). The principles of The Red Queen Hypothesis is clearly formulated in McCune (1982)‚ that states ”all taxa are running on a treadmill powered by an environment which deteriorates at a stochastically constant rate. The result is that an ancient taxon is no better adapted than a younger

Low motivation‚ low self-esteem‚ and debilitating anxiety can combine to ’raise’ the affective filter and form a ’mental block’. Comprehensible input may not be utilized by second-language
