Answer:
A
Explanation:
The structure of ATP is such that there are three (3) phosphate moelcules in sequence attached to the 5’ carbon of the ribose sugar ring. The O- groups of each phosphate are close to each other and are negatively charged. They, therefore, repel each ohtehr electrostatically and make ATP very unstable – hence considered weak bonds. ADP is more stable than ATP. Nonetheless, phosphoanhydride bonds between the phosphate have high energy of ΔG of -30.5 kJ/mol. These characteristic make ATP ideal as ane energy currency since it is easy to hydrolyze while producing much energy.
Mass does remain constant. A is true.
Only the form changes. ( I take that means that a solid is different from a liquid) and that is also true.
Kinetic energy changes. This one is kind of iffy. that means that the temperature will change. Temperature is a measurement of KE. If the change is so much as 1 degree or 1/2 a degree or a millionth of a degree, this is true. It's not very likeable though.
The last one is false. Chemical reactions produce new things. State change only produces something going (say) from a liquid to a solid. There's nothing new being created.

There are two sphincters in the human body
Vegetation bordering a river bank is termed riparian vegetation. It is thought that the land immediately bordering a river is ecologically sensitive and changes in land use in this zone can have disproportionately large effects on the river. Riparian vegetation may play a role in binding soils of a river bank, and their removal can cause bank erosion, which can change the course of a river or exacerbate the impacts of flooding. Changing land use in the riparian zone, such as farming, can affect the water quality of the river, as return from from irrigated crops of livestock will readily enter the river from this zone,
