Answer:
1. Tonga (/ˈtɒŋ(ɡ)ə/; Tongan: [ˈtoŋa]), officially named the Kingdom of Tonga (Tongan: Puleʻanga Fakatuʻi ʻo Tonga), is a Polynesian country, and also an archipelago comprising 169 islands, of which 36 are inhabited.
2. Tonga is the only kingdom in the Pacific since Taufa'ahau (King George) in 1875 declared Tonga a constitutional monarchy, he also gave Tonga its first constitution. In 1970 the former British protectorate acquired its independence and became a sovereign nation.
in the course of fish evolution, two of the gill slits slowly advanced into the jaws.
The evolution of fish started about 530 million years in the past at some point during the Cambrian explosion. It become during this time that the early chordates advanced the cranium and the vertebral column, main to the first craniates and vertebrates. the first fish lineages belong to the Agnatha or jawless fish.
The earliest fish, corresponding to living hagfish, developed about 550 million years in the past. Diversifications that in the end advanced in fish include an entire vertebral column, jaws, and an endoskeleton manufactured from bones in preference to cartilage. Fish live in the course of the sea and in freshwater lakes and streams.
New studies have uncovered the genetic foundation of gill covers in fish, which came about over 430 million years ago. It sheds light on one of the most essential evolutionary traits for fish, in addition to over vertebrates.
In jawless fishes, a sequence of gills opened behind the mouth, and those gills became supported by way of cartilaginous elements. the primary set of these elements surrounded the mouth to shape the jaw.

Nowhere was that diversity more evident in pre-Revolutionary America than in the middle colonies
Answer:
Mammals
Birds
Explanation:
The Organs which perform same function and looks but they are different in their structure from each other are called as analogous organs.
Organs are the structures that made up of two or more tissues organized to carry out a particular function.
An organ or bone that appears in different animals with same function is called homologous structure.
Homologous organs have similar origin n basic structure but perform different functions in different organisms. Analogous organs are different in basic structure but perform same functions.
Different animals have bones that appear very similar in form or function and seem to be related.
Examples
The arm of a human, the wing of a bird or a bat, the leg of a dog and the flipper of a dolphin or whale are homologous structures. They are different and have a different purpose, but they are similar sharing common traits.
The forelimbs of all mammals have the same basic bone structure.The structures are similar because they evolved to do the same job. For example, the wings of bats and birds.

Answer:B. Procedural
Explanation:
Procedural memory is part of our long term memory which equips us with the ability to understand how to do things , which is also referred to as motor skills. Procedural memory restores procedural Information that will let us know what is the procedure we need to take in order to walk ,talk or play.
It tells us how to hold a golf stick and we need to do after that, so it gives us a set of procedures that are required to perform daily tasks.
