maybe A&C? not entirely sure, but thats my best guess!
Explanation:
The highest rate of cell division is a human embryo. Once the sperm finds a viable egg in fallopian tube, it travels to the uterus. Attaches to the uterus where it is called a zygote then begins to multiply rapidly, along with the placenta (from which the developing embryo gets o2, food source, all nutrients a fetus needs to grow,to develop the unborn fetus..
hope this helps..
Answer:
c. Parabasilids
Explanation:
Termites are unable to digest cellulose and lignin by themselves. They need microorganisms living in their guts to provide the necessary enzymes to break down these molecules. This relationship turns to be mutualistic, in which both organisms are beneficiated. The microorganism is an endosymbiont.
Parabasilids are unicellular flagellated protists, most of them symbionts with animals. Flagella are characteristics of this group, arranging into one or more groups in the anterior region of the cell. Many species are commonly found in the digestive tube of termites. Parabasilids help their hosts to digest cellulose through enzymatic action. They are anaerobic organisms and lack mitochondria, making them capable of living in an environment with no fresh supply of oxygen O₂. Termites gut provide all the necessary conditions for endosymbiont´s growth, reproduction, and development.

Answer:
1. Calcium
2. Calcium
3. Iodine
4. Sodium
5. Cobalt
Explanation:
Calcium is an essential nutrient which provide rigidity to skeleton by virtue of insoluble salts it form with phosphoric acid hydroxyapatite. It plays important role in muscle contraction, hormone release, nerve conduction, blood coagulation, bone and teeth growth and metabolic process like enzymatic reactions.
Iodine is important in the normal functioning of the thyroid gland, it is required for the synthesis of thyroxine (T4) and tri-iodothyronine (T3) which affect many metabolic processes.
Sodium is the most abundant positive ion, there are approximately 3000mmol of sodium in extracellular fluid. It account for the osmotic activity of the extracellular fluid compartment. It is also an important in the development of action potential for muscle and nerve conduction.
Cobalt is and important component of both vitamin B12 (cyanocobalamin) and red blood cells.
