Answer:
The correct is B Hormones are chemical signals between cells transported in blood or hemolymph.
Explanation:
Hormones are called chemical messenger of the cell because they transmit chemical information from one cell to the target cell and regulating the functioning of that target cell by activating specific proteins related to the functioning of that target cell.
Hormone is secreted from its source gland such as Pituitarygland, thyroid gland,adrenal gland.After being secreted hormones are transported via the blood stream to the target cell and binds to receptor of that target cell thus allowing the target cell to exert its biological function.
All of the above are needed. Nucleotides are the basic building blocks of new DNA, ATP energy is needed because replication is an active process, and enzymes catalyze the reactions needed to carry it out (e.g. helicase to separate the strands to be replicated, DNA polymerase to build the new strands, and ligase to "glue" the fragments together).

Explanation:
Answer:
A. produce larger materials from the collision of smaller materials
Explanation:
The outcome of nuclear fusion reaction is that it produces larger materials from the collision of smaller materials.
- Nuclear fusion is the combination of small atomic nuclei into larger ones with the release of a large amount of energy.
- The energy released provides the needed temperature for another set of atoms to fuse.
- This process in turn yields a bulkier material accompanied with the release of a lot of energy.
