## What is the biological significance of lipids?

The lipids of physiological importance for humans serve as structural components of biological membranes; provide energy reserves, predominantly in the form of triglycerides, serve as biologically active molecules exerting a wide range of regulatory functions, and the lipophilic bile acids aid in lipid emulsification

## What is the biological significance of water having high surface tension?

High surface tension and cohesion: Water has a higher surface tension than any other liquid. The high cohesion of water molecule is important in cells and in translocation of water through xylem in plants. Many small organism rely on surface tension of water to settle on water or to skate over its surface.

## What’s a significant p-value?

Article. The p-value can be perceived as an oracle that judges our results. If the p-value is 0.05 or lower, the result is trumpeted as significant, but if it is higher than 0.05, the result is non-significant and tends to be passed over in silence.

## What does P 0.05 level of significance mean?

P > 0.05 is the probability that the null hypothesis is true. A statistically significant test result (P ≤ 0.05) means that the test hypothesis is false or should be rejected. A P value greater than 0.05 means that no effect was observed.

## What does a significance level of 0.05 mean?

The significance level, also denoted as alpha or α, is the probability of rejecting the null hypothesis when it is true. For example, a significance level of 0.05 indicates a 5% risk of concluding that a difference exists when there is no actual difference.

## What does significance mean in history?

Historical significance is a decision that modern people make about what is important from our past. In assigning historical significance, we can choose specific events, people, locations and ideas as being particularly important to us.

## What do you mean when you say there is significant difference?

## How do you know if there is a significant difference?

You may be able to detect a statistically significant difference by increasing your sample size. If you have a very small sample size, only large differences between two groups will be significant. If you have a very large sample size, both small and large differences will be detected as significant.

## How do you find the significance level?

To find the significance level, subtract the number shown from one. For example, a value of “. 01” means that there is a 99% (1-. 01=.
