Answer:
the last one which I'm guessing is d......cause it kinda messed up
<span>1. taxonomy is a branch of science concerned with classification of organisms
hence (5) Classification matches with Taxonomy
2.Species is the biological term referring to the basic unit (smallest rank) of classification:
hence (1) smallest unit of classification matches with Species
3.Arthropods are animals which have an exoskeleton, segmented body and paired jointed legs
hence;
(2) segmented digestive system, appendages, matches with Arthropoda and Animal characteristics
4. Tracheophyta refers to green plants which have conductive tissues (vascular tissues) for conducting water and nutrients through them.
The description " (4) Green, conductive tissue, seeds, flowers, and (7) largest division of plants term, they match with Tracheophyta and Plant Characteristics
5. in taxonomy (organisms classification) the Order, ranks in between Class and Family, hence of families makes an Order.
Therefore, (6) groups of families matches with Order</span>
