Answer:
White
Immune
Explanation:
White blood cells, also called leukocytes, are one of the cells that are involved in the body's immune system. They protect the body against various infections diseases and other invaders. Leukocytes are produced in the bone marrow (hematopoietic stem cells). They are not the only cells that are important for the defense of the body but are important.
Answer:
Signal transduction pathways
Explanation:
Plant hormones act by directly affecting the activities of signal transduction pathways.
Signal transduction pathways are involved in the transfer of signals from outside of the cell to the inside of the cell for the regulation of various cellular activities. For this, the extracellular signalling molecules bind to the receptors that are located on the cell membrane. After their binding due to some change in the receptor molecule, a signal is triggered in to the cell and thus information from outside of the cell is transferred to the inside of the cell through these transduction pathways.
Plant hormones affect these pathways and as a result membranes, enzymes, and genes are also influenced by the plant hormones.

ANSWER:
Index Fossils can be used to identify a specific period of time
Answer:
Interphase within sequences of cellular processes After the successful completion of mitosis and cytokinesis, both resulting daughter cells re-enter G1 of interphase. In the cell cycle, interphase is preceded by telophase and cytokinesis of the M phase.
