Answer:
Explanation: Even though frogs don't look much like people on the outside, their skeletons are similar to people's skeletons, especially when it comes to their limbs. Just like in a person's arms, in a frog's front legs are bones called the humerus, the radius and the ulna. However, a frog's radius and ulna are fused into one bone.
The similarities between sharks and dolphins are : Analogous
<h3>What are analogous structures ?</h3>
Analogous structures are similar structures present in different species that do not share the same/common ancestor.
The similarities between sharks and dolphins are streamlined bodies and the possession of fins and they are analogous structures because they evolved differently for sharks and dolphins as they do not share a common ancestor.
Hence we can conclude that The similarities between sharks and dolphins are : Analogous

Answer:
A
Explanation:
Condensation is the process of vapor turning into liquid water
Answer:
The diversity of species
Explanation:
Darwin investigated the diversity of species by observing the physical differences between them. He concluded that all the species came from the same ancestor in common. And that the evolution is given by natural selection (or adaptation to the environment). Only specimens more adapted to the environment could survive, reproduce and pass their genetic traits to their offspring.
For example, the long neck of the giraffes is due to the fact that only the highest ones reached the leaves of the trees for food and with that they managed to survive.
B: the gravel on the bottom of the aquarium, because it is not a living thing like the algae, plants and fish.
