Answer:
A metallic bond of copper atoms with metallic bond of tin atoms to form metallic bond.
Explanation:
Metallic bond is a type of bond that is formed between positively charged atoms in which there is sharing of electrons between them.
Metallic bonds are formed between metal atoms. When metal atoms unite, they share electrons among themselves and each one of them has valence electrons.
Bronze is an alloy of metals and it consist of copper and tin which makes them to be bonded by metallic bond.
I would choose answer choice D.
Sexual reproduction makes genetically diverse offspring, while asexual reproduction makes genetic clones of itself, and doesn't require another parent.
The answer is speciation by geographic isolation. When the population of a species gets separated due to reasons such as continental drift, mountains, canyons, etc. then each separated group of population may survive and adapt to their respective environment leading to speciation. These barriers do not allow the evolving populations to interbreed initially and over time when they evolve into different species they become completely reproductively isolated.
