Australia's animal populations adapted to a unique ecosystem after separation from other plates.

Answer: Option D

<u>Explanation:</u>

Australia has unique species of animals compared to the rest of the world because of it's long time separation from the other continents which led to the adaptation of the animals on this continent to the unique ecosystem of Australia resulting in some unusual Australian animals. The animals which were originally on Australian landmass had no more contact with the animals in other part of the world, thus they developed independently.

ra1l [238]

Answer: c. Margaret may claim her mother as a dependent if her sister agrees in a multiple support agreement.

How does the author’s discussion of code-breaking contribute to an understanding of Grotjan’s skills?
mario62 [17]

Answer:

In understanding Grotjan's skills, the author's discussion of code-breaking revealed that coded messages are made up of numbers and letters in a pattern. Each of the symbol in the pattern usually represent a letter. Whenever the machine moves, a letter tends to move and a symbol stands out for something different. This makes such code difficult to solve, decipher and decode.

In order to break the codes, cryptanalysts use guess work. They try out a combination of letters.

For example, in cracking Japan's diplomatic coded messages, cryptanalysts used a combination of letters from this Japanese popular saying: "I have the honour to inform Your Excellency".

They tried out a combination of letters through guessing.

Explanation:

Grotjan's discovery in World War II led to the development of a Purple Cipher machine which was built by SIS and the U.S Navy. It was used to read and decode Japan's most diplomatic messages. People saw the breaking of Japan's diplomatic coded messages as a "magic".

"Cracking Code Purple" is an informational text written by Ann Ouchychy. It reveals the impact of Genevieve Grotjan, a female code breaker during World War II.
