Each colony is populated with the same number of mature fireflies. After 72 hours, you count the number of living fireflies in each colony. (a) Is this an experiment or an observation study? Explain.

What does the term in media res mean and how does it function in The Odyssey​
aksik [14]

The term 'In medias res' is a Latin phrase which means 'In the middle of things or events'.

Explanation:

The term 'In medias res' is a Latin phrase which means 'In the middle of things or events'.

In Homer's epic, Odyssey, he begins with the phrase In medias res. The story thus begins with the wanderings of Odysseus and then goes on with the Trojan War. Knowing the journey of Odysseus, it creates interest in the reader.  The story becomes enjoyable by the narration of Odysseus's journey rather than beginning with the winning of the Trojan war.

ratelena [41]

<u>Answer:</u>

<em>Serving a two or six year term is not the function of legislative branch.</em>

<u>Explanation:</u>

The <em>legislative branch of the US</em> is made up of the Senate and the House of Representatives respectively called the upper and lower house. The term of both the houses is 4 years. Thus the option which says it serves for a two or four year term is wrong

The legislative performs various functions like <em>making laws, maintaining interstate and national commerce regulations, formulating taxation policies etc.</em> Several organizations come under the legislative branch.
