The correct answer is iron, because it is often not included in children's multivitamin/mineral supplements. Iron is an important element for our health. It is especially important for the proper functioning of our red blood cells and it is found in many foods. Although iron is essential, too much can lead to iron toxicity. Iron poisoning was the leading cause of death from the medicine overdose in children younger than 6 years until the ends of the 1990s. But the trend has since changed due to better warning labels, education of prescribers, changes in iron preparations, and consumer awareness.
Answer:
I think it is C 10percent.
Explanation:
Answer:
Producers are capable of photosynthesis, a process by which they covert light energy into chemical energy, while consumers use respiration. Producers generate complex organic molecules, while consumers break them down into simpler ones (say, sugars to carbon dioxide, etc.).

Answer:
Pros-
Geothermal energy is generally considered environmentally friendly and does not cause significant amounts of pollution.
Geothermal reservoirs are naturally replenished and therefore renewable (it is not possible to exhaust the resources).
Massive potential – upper estimates show a worldwide potential of 2 terawatts (TW).
Excellent for meeting the base load energy demand (as opposed to other renewables such as wind and solar).
Great for heating and cooling – even small households can benefit.
Harnessing geothermal energy does not involve any fuels, which means less cost fluctuations and stable electricity prices.
Small footprint on land – can be built partially underground.
Geothermal energy is available everywhere, although only some resources are profitably exploitable.
Recent technological advancements (e.g. enhanced geothermal systems) have made more resources exploitable and lowered costs.
Cons
- There are some minor environmental issues associated with geothermal power.
Geothermal power plants can in extreme cases cause earthquakes.
There are heavy upfront costs associated with both geothermal power plants and geothermal heating/cooling systems.
Very location specific (most resources are simply not cost-competitive).
Geothermal power is only sustainable (renewable) if the reservoirs are properly managed.

Answer:
B. GUC only
Explanation:
Transfer RNA (tRNA) is a special type of RNA molecule that plays a vital role during translation. It matches an mRNA codon with its corresponding amino acid. The tRNA does this through a set of three nucleotide sequences called ANTICODON, that it contains.
The tRNA reads the mRNA codon using its anticodon, which is complementary to the mRNA codon. The reading is done following the complementary base pairing rule i.e. A-U and C-G.
Hence, a mRNA codon with nucleotides CAG will be read by a tRNA codon with GUC nuceleotide, which is complementary to it. Note that, the complementarity of the anticodon sequence makes it oriented in the 3'-5' direction.
