Answer:
on the surface rapidly
Explanation:
Obsidian glassy texture indicates that the rock formed on the surface rapidly.
Like every other magma, the condition of the environment determines how the magma cools and solidifies.
- When magma cools rapidly, nucleation centers will be difficult to come- by ..
- At nucleation centers, minerals aggregates and grows to form different grain sizes.
- When rapid cooling occurs, not enough time is given for the aggregation around the nucleus.
- This leaves a rock mass that is finely grained.
Answer:
B. Masturbation.
Explanation:
Mutual masturbation occurs when two people masturbate together with consent.
Coitus is sexual intercourse, so two people are needed and doesn't count as masturbation per se.

Cunnilingis is oral stimulation of a female's vagina.
Hope this helps :)
I think it could be letter B maybe I may be wrong I’m a beginner
The right answer to this question is option C. the traits acted upon natural selection were genes.
At the time Charles Darwin developed the evolution theory, there wasn't a single study about genes in all science scenery, that could be explained by the lack of technology to study them and even to know they existed in the first place.
So, his theory was basically talking about adaptation, if an organism can't survive a specific environment, he'll probably die until another generation comes in and this one can survive in this environment, passing their genes to the next ones. The lack of information was the knowledge about the genes we have today, that's why most scientists take only the new Darwin theory, that includes the study of genes.
Fungi are eukaryotic and saprophytic microorganisms that grow on dead and decaying matter. These organisms release digestive enzymes that break down leaves, fruit and other organic material into simple molecules. These can grow on wood, clothes, food, fruits, leather shoes, etc by breaking down complex organic matter into simpler forms with the help of extracellular digestive enzymes such as cellulases, proteases, phosphatases, etc.
