The answer is Dendroaspis Polyepis (according to Google)
Answer:
A pH indicator is able to tell what level of pH the substance is at. It can tell how acidic a substance is. If a substance has more hydrogen ions than hydroxide ions then it is acidic. If it has more hydroxide ions that hydrogen ions it is an akaline. the acidic scale is from 0 to 14. lower numbers means more acidic and higher numbers means it is an alkaline.
Explanation:
pH stands for potential Hydrogen.
Statistical power is the likelihood that a test (statistical test) will detect an effect when there is an effect there to be detected. Statistical power<span> is inversely related to </span><span>the probability of making a </span>Type II error (Type II errors<span>, or </span>false negatives, occur when you don’t see things that are there) = beta<span>.
statistical power = 1 – </span>β. The critical value<span> is the </span>value corresponding to a given significance level. The statistical power<span> is </span>influenced by the choice of significance level for the test (by the critical value). Larger critical value means increased power of the test: <span> the chance of obtaining a statistically significant result is increased (reduces the risk of a </span>Type II error<span> (false negative regarding whether an effect exists) is reduced) . </span>
Scientists have inferred that helium hydride was this first, primordial molecule. Once cooling began, hydrogen atoms could interact with helium hydride, leading to the creation of molecular hydrogen — the molecule primarily responsible for the formation of the first stars.
