Ecological niche modelling is used to predict the distributions of species. As a general rule, which of the following statements is true?

#Unit 10. Ecological Principles
  1. Distributions of species do not reflect the range of physical conditions that support the survival and reproduction of individuals

  2. The more suitable the conditions for a species, the denser its population, and the greater its productivity

  3. Changes over time in conditions such as temperature, precipitation, and salinity have not been shown to affect the distribution of marine fish species
  4. Global climate change always results in a decline in the number of species inhabiting a given area

Choose the incorrect statement regarding the Van der Waals interactions & Hydrogen bonds
1. In Van der Waals interactions greater the area of contact the stronger the interaction.
2. In Van der Waals interactions greater the area of contact the weaker  the interaction.
3. Hydrogen bonds Relative strength is inversely proportional to the polarity More polar atoms form weak H bonds.
4. Hydrogen bonds Relative strength is directly proportional to the polarity More polar atoms form stronger H bonds.
