Water molecules consist of 2 Hydrogen and 1 Oxygen atom. They are bonded by a polar covalent bond, meaning the electrons shared by the covalanet bonds are not evenly distributed. Oxygen is more electronegative than Hydrogen and will pull the electrons from its bonds with Hydrogen closer to itself. Thus results in a partial positive dipole on the Hydrogen of the water molecule and a partial negative dipole on the Oxygen of the water molecule. These partial charges allow water to hydrogen bond with one another through a process called cohesion.
Answer:
Inter-rater agreement
Explanation:
The extent to which two or more raters (or observers, coders, examiners) agree is termed as Inter-rater agreement. It addresses the issue of consistency of the implementation of a rating system.
A high inter-rater agreement value refer to a high degree of agreement between two examiners, vice-versa
Answer:
D) Competition between organisms
Explanation:
Random mating between organisms, absence of any factor of evolution (mutation, recombination, gene flow, migration etc.) and a large population size serve to maintain the allele frequency and thereby the phenotype frequency over generations. However, competition between organisms for any natural resource leads to natural selection of "better competing organisms" and increases their phenotype frequency in the population.
