D. Both partners need to br treated at same time.
Answer:The discovery of the "distal-less," or Dll, gene in many different phyla.
Explanation: Appendages of animals are any external attachment or extension of one or two body parts of an organism in order for it to be able to effectively perform its responsibilities.
The morphological and functional changes or evolution of appendages is responsible for the adaptive radiation of tetrapods, arthropods and winged insects. Recent studies tends to show that all animal appendages may be homologous through the discovery of the "distal-less," or Dll, gene in many different phyla.
<span>the lacrimal bone helps form the nasolacrimal canal necessary for tear translocation. A depression on the anterior inferior portion of the bone, the lacrimal fossa, houses the membranous lacrimal sac. Tears or lacrimal fluid, from the lacrimal glands, collect in this sac during excessive lacrimation. The fluid then flows through the nasolacrimal duct and into the nasopharynx. This drainage results in what is commonly referred to a runny nose during excessive crying or tear production. Injury or fracture of the lacrimal bone can result in posttraumatic obstruction of the lacrimal pathways</span>
Answer:
No
Explanation:
Because the xylem transports the water to the plant therefore cutting it off will make it fall to its death
