Answer:
1. Bats and cats: <em>Homology</em>
2. Whales and sharks: <em>Analogy</em>
Explanation:
In Biology, homology refers to <u>the similarity of features from different species of organisms that share a common ancestor</u>. This is the opposite of analogy, which refers to <u>a feature that has a similar function but is not derived from a common ancestor</u>.
In this case, bats and cats have forelimbs adapted for locomotion. This is a case of homologous characters because they both are descendants of tetrapods - four-limbed animals. Therefore, even though cats and bats look completely different, they both share a similar feature: forelimbs, a characteristic feature from their common early mammalian ancestors.
On the other hand, whales (mammals) and sharks (fish) do not share a common ancestor. So, the fins are analogous structures: both have a similar function because both have adapted to an aquatic environment but they have completely separate evolutionary origins.
The correct answer is short-term memory.
Short-term memory (STM) refers to our ability and capacity for retaining a small amount of information for a short period of time. Remembering an unfamiliar phone number entails the use of our STM. However, a phone number is difficult to retain in our STM because STM has a digit span of approximately seven units. This means that our STM can hold around seven digits of a phone number and not all (10+) of them.
Answer:
B
Explanation:
because it happened in 1846
The Persian Wars wound up strengthening Greece, particularly Athens and Sparta, and weakening the Persian army and navy to the point where Alexander the Great (of Macedonia) with a combined Greek army, was able to defeat Persia in his expedition two generations later.
