D.) Because the leaf is coated in lipid molecules

A is wrong because water is polar, an example of nonpolar is oil, and everyone knows that oil and water do <em>not</em> mix! Their molecules just aren't attracted to each other.

B is wrong because, like I said, water is polar.

C is wrong because cellulose is one of the most abundant organic compounds on the Earth, and it's a major component of the cell walls in plant cells.

construct a dichotomous key which can be used to identify the five antelopes shown in figure 1.1 use only visible features.​
Bas_tet [7]

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.
