Final answer:

In biology, the null hypothesis is usually rejected if the p-value is less than 0.05. This suggests that the null hypothesis is false and supports the alternative hypothesis. If the p-value is not less than the significance level (a = 0.05), we do not reject the null hypothesis.

Step-by-step explanation:

In the biological sciences, the null hypothesis is usually rejected if the p-value is less than 0.05. When the p-value is less than the significance level (a = 0.05), it provides significant evidence to suggest that the null hypothesis is false, and we reject it in favor of the alternative hypothesis. However, if the p-value is not less than the significance level, we do not reject the null hypothesis.
