Answer:

A

Explanation:

Isotopes are atoms of the same element with the same number of protons and electrons but different numbers of neutrons.

Isotopes can also be defined as atoms of the same element with the same atomic number but different mass numbers e.g isotopes of chlorine, oxygen and so on.Oxygen for instance has three isotopes with the same atomic number,8 and different mass numbers,16,17 and 18.

Tanzania [10]

Answer:

A.  Herbivores have longer digestive systems than carnivores have.

Explanation:

We can conclude that the herbivores have longer digestive systems compared to carnivores.

Carnivores feeds on other animals whereas herbivores eats plants.

  • Most herbivores have a four stomach compartment system that helps them process and digest their food.
  • This is because they have to process cellulose in plants which needs to be properly broken down.
  • Flesh eating carnivores do not require this arrangement.
  • The four stomach compartment of most herbivores includes Rumen, Reticulum, omasum and abomasum.
  • They also chew the cud whereby they regurgitate food materials.

Functional groups create active sites in molecules. The polar part of a molecule that can hydrogen bond to water is said be hydr
VMariaS [17]

Answer:

Polar/Hydrophilic

Explanation:

Fluorine, Nitrogen and Oxygen are strong electronegative atoms and by definition, Electronegativity is the amount of pull or the high affinity of an atom to electrons.

Polar bond occurs when there is a high difference between the electronegativity value of both atoms that take part in the bond.

A polar molecule has a net dipole from the distribution of its positive and negayive charges. Hydrophobic and Hydrophilic (in chemistry, Polar) are terms dependent on the overall distribution of charge in its molecule.

Therefore, bonds between C-N, C-O and C-Cl are polar covalent bonds a d this is because of the jigh electronegativity possessed by Nitrogen, Oxygen and Chlorine.
