Limestone is composed largely of the minerals calcite or aragonite. Some limestones do not consist of grains and are formed by the chemical precipitation of calcite or aragonite. This is how limestone can be classified as chemical.
Over time, rain and weathering causes rocks to release phosphate ions and other materials. This inorganic phosphate is then distributed into the soil and water. plants take up inorganic phosphate from the soil. the plants may then be consumed by animals. Once in the plants or animal, the phosphate is incorporated into organic materials that break down organic matter to inorganic forms of phosphate. this process is known as mineralisation. Phosphate in soil can end up in waterways and eventually oceans. once there, It can be incorporated into sediments over time.

Answer:
Because gene therapy procedures are still in their infancy, some hazards are unknown; nonetheless, medical researchers, institutions, and regulatory authorities are attempting to make gene therapy research, clinical trials, and approved therapies as safe as possible.

Answer:
The absorbency will be 0.6 (letter C)
Explanation:
A process that decreases the amount of a solute in a solution is called dilution. Dilutions are made by adding more solvent to the solution (the universal solvent is water).
In this case, we have a 0.5 ml of a solution with a specific concentration that the absorbency is 1.2. We dilute this solution adding 0.5 ml of water (the same amount of our solution or initial volume). Then we have the double (1 mL) of the initial volume (0.5 ml), this means that the concentration will be the half (0.6) of our initial concentration (1.2).
In mathematical terms, we can use the next formula
:
(C1)(V1) = (C2)(V2)
Where:
C1: initial concentration
V1: initial volume
C2: final concentration
V2: final volume
We now that:
C1: 1.2
V1: 0.5 ml
C2: ?
V2: 1 ml
Using the formula, we have:
(1.2)(0.5 ml)=(C2)(1 ml)
As the 1 ml is multiplying, pass to the other side dividing
C2= (1.2)(0.5 ml) /(1 ml)
C2= 0.6 /1
C2 : 0.6
