It might be. In general, parental or guardian permission should be sought before seeking the assent of a child, particularly in more than minimal risk research, unless the requirement for obtaining parental or guardian permission can be waived. There might be some cases, however, involving minimal risk research, where it would be reasonable to seek child assent prior to seeking parental permission.
You didn't provide a lot of information so I did some research on your question. If this context looks right then this is the answer! :D
Question that I think you got:
"A geologist finds a metamorphic rock and notices that it has grains that formed in parallel layers. The geologist pries at the rock, and it splits apart along the bands formed by the layers.
<em>Which type of rock did the geologist most likely find?</em>
gneiss
limestone
marble
sandstone"
Answer:
Gneiss
Explanation:
Metamorphic rocks are classified based on their grain arrangement into foliated rocks and non-foliated rocks. These foliated rocks are the ones in which the grains are arranged in parallel layers bands which allows them to split apart along these band. Some common examples of foliated metamorphic rocks are slate, schist, and gneiss which gives us our answer of geniss. (some of the answer from "podgorica" on Brainly)
Answer:
The activation energy depends on reactive species.
Explanation:
The minimum amount of energy required by the reacting species in order to start a specified reaction is called activation energy. Without activation energy, the reaction can be started so activation energy is very important for occurring of a chemical reaction. There are different amount of activation energy is needed to start different chemical reactions so we can conclude that activation energy depends on the type of reactive species and on the reaction.
