Answer:
If damage is done to the human skeletal structure it cannot be healed or reversed: INCORRECT.
Explanation:
- Human DNA is capable of repairing itself: <em>CORRECT.</em> It has several ways to do it, repairing bases through excision, by photoreactivation, repairing mismatches, by repairing double-strand breaks and activating SOS responses.
- If damage is done to the human skeletal structure it cannot be healed or reversed:<em> INCORRECT.</em> The human body has a bone healing process that allows the creation of a cartilaginous scaffold than then becomes a bone matrix transforming the outer laminar bone into compact bone.
- The human skin is capable of self-heal due to the human cells: <em>CORRECT. </em> A wound in human skin is healed in a process that includes hemostasis, the creation of a blood clot, followed by an inflammatory phase and de successive creation of new epidermis. Many human cells are involucrated, such as fibroblasts and macrophages.
- When synthetic material gets damaged it's irreversible: <em>CORRECT. </em>These kinds of materials do not have a system to self-heal by itself.
- Biological material has the capability of healing due to vascularity and its cells: <em>CORRECT.</em> Vascularization is the growth of blood vessels, it is fundamental to have effective transport of oxygen, nutrients, and removal of cell-secreted waste for the survival of cells, this allows the biological material to heal.

Answer:
In conclusion, the net ionic equation for the reaction between calcium carbonate and hydrochloric acid is CaCO3 solid plus two H+ aqueous react to form Ca2+ aqueous plus CO2 gas plus H2O liquid.
As we know that
A<span>t STP
1 mole of any gas occupies 22.4L
so
15.7L / 22.4L/mole = 0.7moles Cl2
0.7moles x 6.022x10^23molecules/mole = 4.22x10^23molecules
hope it helps</span>
Answer:
Volcanoes, burning fossil fuels, and respiration of organisms.
Explanation:
Volcanoes, burning fossil fuels, and respiration of organisms releases carbondioxide that forms atmospheric carbondioxide. The carbon enters in the biosphere through the process of photosynthesis. In plants, carbondioxide enters in the plant body which is used as a reactant from which food is prepared. The carbon present in the plant body in the form of glucose which can be transferred into another organism due to feeding of organisms. The organism released this carbon in the form of carbondioxide when the eaten food is broken down for the release of energy. In that way, carbon moves from biosphere to the atmosphere whereas Volcanoes and burning fossil fuels releases carbon in the atmosphere, in this way carbon moves from lithosphere to atmosphere.
The amount of Al required will be 15.77 grams
<h3>Stoichiometric problem</h3>
First, the equation of the reaction:
The mole ratio is 2:3.
Mole of 63.0 g of FeO = 63/71.84 = 0.8769 moles
Equivalent moles of Al = 0.8769 x 2/3 = 0.5846 moles
Mass of 0.5846 moles Al = 0.5846 x 26.98 = 15.77 grams
