Answer:
Electronegativity values between atoms in a polar covalent bond have differences that lie between 0.4 to 1.7 which is clearly less than 1.7.
Missing term : Less
Explanation:
Electronegativity as we all know is the capability of holding the valence electrons by the atoms while forming bonds with one another. Now, when two atoms come together to form any kind of bonds, they tend to either lose their electrons, gain electrons from the other atom or collaborate to share them together.
To know at what instinct, the atoms are going to either form a covalent or an ionic bond, we need to know the difference between the electronegativity of both the atoms. this difference in electronegativity, defines the nature of the bond between them.
If the difference in electronegativity of atoms lies between 0.4 to 1.7, they tend to form a polar covalent bond and acquire a partial positive and negative charge, the electron being more biased to one of the atom.
On the other side, when the difference come greater than 1.7, the atoms tend to have a non-polar bond where they share the electrons with each other. Water is a good example of non-polar covalent bond.

Answer:
D. has a wide variety of plant and animal life
Explanation:
Biodiversity means the variety of plant and animal life in the world or in a particular habitat, a high level of which is usually considered to be important and desirable.
Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. For example, A larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all life forms.
It has been estimated that more than 50 million species of plants, animals and micro-organisms are existing in the world. ... Biological diversity or Biodiversity is defined as the variety and variability among the living organisms and the ecological complexes in which they occur.
