A substance that releases hydroxyl ions in water is a base. Acids on the other hand release hydrogen ions when dissolved in water, while salts release sodium. To define acids and bases the Arrhenius definition is used by scientists---this describes what substances are produce by each type of solutions. Under the Arrhenius definition salt and water can be used to predict the result of the neutralization of an acid with a base.
In Chemistry, Bronsted-Lowry definition has superseded the Arrehenius definition.
Answer is A. Calvin cycle.
Calvin cycle reactions or light independent process of photosynthesis occurs in the stroma (Ground substance) of the chloroplast. In the stroma enzymes are present for the Calvin cycle reactions. Carbon dioxide (CO₂) enters into the leaves through stomata and diffuses into stroma of the chloroplast. In the stroma carbon atoms from CO₂ is fixed into sugar (carbohydrate) with the help of energy from ATP and NADPH.
Answer:
D. the law of crosscutting relationships
Explanation:
The law of cross-cutting relationships can help explain the age of the rock as it relates to the surrounding rock.
This law is one of the premise of relative dating. The relationship between the intrusion and rock body or country rock is used to discern their age.
- When intrusions cross-cuts the host rocks, they are usually younger.
- The host rock must haven emplaced before the intrusion sets in
- The intrusion utilizes weak planes within the rock body to cool and solidify.
- Now, when they are emplaced, then a vein or other intrusive bodies forms.
