Explanation:
<em>Tracheophytes are distinguished from bryophytes by their highly developed vascular systems, which facilitate the transport of water and nutrients to all parts of the plant. This vascularization adaptation has allowed tracheophytes to become more fully terrestrial than bryophytes, which are still dependent upon moist environments for many reproductive and nutritive functions, as discussed in Bryophytes. Tracheophytes can be broken down into three classes: ferns, gymnosperms, and angiosperms. Ferns are the least evolved of the tracheophytes; they have vascular systems, and specialized leaf and root structures, but are still dependent on moist environments for reproduction. Gymnosperms (coniferous plants) and angiosperms (flowering plants), known together as the seed plants, have evolved reproductive processes that are independent of water. In addition, tracheophyte seed plants all produce embryos that are encased in tough coats. These seed coats prevent desiccation in a terrestrial environment and protect the seed until conditions are favorable for growth. Angiosperms can be further classified as monocots and dicots, depending on their embryonic development and other factors.</em>
Parasites are organisms that live in the gastrointestinal tract of animals, including humans. They can cause diarrhea
ATP is an energy source for cell processes and its made during respiration
The atomic number would be 80.
Answer:

Explanation:
When DNA is copied the process is called replication since the DNA is being copied.
