This image shows the Hox genes for a fruit fly, and which parts of the fly embryo and adult they code for. Describe a possible developmental problem in the fruit fly if the fifth (yellow) Hox gene was mistakenly activated in the head area.

Mutations in this Hox gene cause a small, malformed jaw in mice, “split-hand/foot malformation” in humans, and legs and antennae popping up where they don't belong, or missing where they do belong, in flies

Explanation:

The Yellow is the problem.

The head the thorax and abdomen.

answer: tributaries flow into rivers.

wetland is a biome that develops when the water gets accumulated in a land exhibiting a huge depression. these form either seasonally or permanently. the water in the wetland comes from rivers, lakes, ocean, flood, rain or other sources. the wetlands includes mangroves, marshes and peatland.

tributaries flow into the rivers develops a wetland because such water will get deposited in the depression and will restrict the original flow of tributary water. hence, water with low drainage current combines with the river water.
