Answer:
When comparing homologous structures, we are comparing the anatomy of one part of an organism to another and finding it to be structurally similar but functionally may be different. Let’s compare a couple of tetrapods, specifically a human arm and a cat arm.
Both the human arm and the cat arm have a single bone in the upper arm, which we call the humerus, followed by two bones in the forearm–the radius on the more medial side and the ulna on the more lateral side. Both arms also have a common wrist structure followed by a grouping of metacarpals and phalanges. All of these structures are similar; however, these structures do not have the same function. Cats are quadrupeds that use their arms for walking and maybe a little climbing and hunting for outdoor cats. Humans, on the other hand, use their arms and hands for gross motor movement like grabbing, hugging, and lifting, as well as fine motor movement like using tools or even communicating.
A whale flipper and a bat wing are also homologous structures in the same sense as a human arm and cat arm with a humerus, radius and ulna, and so on. But the whale’s “arm” is actually a flipper that it uses to swim while the bat uses its wing to fly.
Answer:
Atoms of the same chemical element do not always have the same mass because, although the number of protons in the nucleus is the same for all atoms of the same element, the number of neutrons is not. Most elements as they occur naturally on earth are mixtures of several isotopes.

Answer:
The majority of the research shows that the plates move at the average rate of between approximately 0.60 cm/yr to 10 cm/yr. Some sources state that in the North Atlantic, the rate of movement is only about 1 cm (about 0.4 in) per year, while in the Pacific it amounts to more than 4 cm (almost 2 in) annually, while others say that plates, in general, travel from 5 to 10 cm/yr.

The Eurasian Plate is moving away from the North American Plate at a rate the is about 3cm per year. That is about the same rate at which your fingernails will grow.

The distance from New York to London is in 3459 miles (5567 km). What will the distance be in 5 million years?.


The distance from New York to London in 5 million years will be 3552 miles (5717 km). So if today it takes us 7 hours and 30 minutes to fly to London at a speed of 460 miles per hour, in 5 million years at the same rate of speed will take us close to 8 hours.
