The dichotomous key used to identify the antelopes might be based on the presence/absence of certain muscles, weight, etc.
<h3>What is a dichotomous key?</h3>
A dichotomous key is a system to classify species and/or taxonomic groups by using two different choices.
For example, the presence/absence of certain physical features can be used to identify the antelopes.
Moreover, the threshold in certain features such as weight/height can also be used to classify species.

Number of mole s of H
2
= 0.25 moles
number of molecules = moles * Avogadro’s Number
number of molecules = 0.25×(6.022×10
23
)
number of molecules = 1.505×10

single molecule of hydrogen contains two H-atoms. So,
number of atoms = 2×(1.505×10
23
) = 3.01×10

All LIFE as we know it on Earth is dependent on THE SUN.
Answer:
below
Explanation:
there are so many different kinds of living things that its so difficult to classify them as there would be too many classifications that it would become absurd to have only a few organsims in a single group. the role of classification is to organize as well as simplify so it proves to be a challenge when the subgroups branching from eukoryotes vs prokaryotes become too small and therefore it becomes a giant mess. even the current classification system (taxonomy) is flawed.
