Answer:
Speed of the bicycle= 2 m/s
Time taken by Salma to reach school from her house = 15 minutes = 15 × 60 s = 900 s
We know that speed = distance / time
Hence Distance = Speed × time
= 2 m/s × 900 sec
= 1800 m
=1.8 km
Distance between Salma's house and school =1.8 km
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.
I think the correct answer would be that when <span>people feel the need to escape,they may move to another area. When people are persecuted, they definitely would feel danger in their lives and to protect the lives they would tend to migrate to other place where they are safer.</span>

Explanation:
Mindy's experience best illustrates <u>mood-congruent memory</u>.
<u>Explanation</u>:
Fear is an unpleasant feeling which occurs due to danger or insecurity.
Mood-congruent memory is the place where humans store their memory. It is evident that when we store memory, we not only store the event, but we also store the mood of the event.
So when we recall our memory, we are able to recall the mood at the time of event. If we are happy we will be able to recall the happy memories.
