Billions of years ago Earth was just a planet made out of rocks. After the Big Bang Theory, Earth was being formed. After it was formed it took years and years for life to even start on earth. What started life was when Earth started to produce it's own water then soon it made volcanoes which made islands which formed into gigantic places that we call home. Later on Earth started to produce it's own weather and atmosphere. As earth had it's first rainfall, the ground started to grow green leaves that we call grass and trees. With those changes, life was starting to be born. The first living things on Earth, singled-celled micro-organisms or microbes lacking a cell nucleus or cell membrane known as prokarotes. Later on the the organisms starting producing more organism which evolved later into human and animal life.
Hope this helped <span />
Answer:
C. Using the scientific method
<span>A hydrophillic amino acid will have it's functional group positioned where the water is. Generally this will be outside of the polypeptide, and the amino acid will interact with polar entities, this will include other amino acids that match it's polarity.</span>
Maximum Thrift is a method / philosophy that considers the shortest tree (in number of transformation steps) the best hypothesis about the phylogenetic relationship of a given set of terminals. Transformation step is the cost attributed to the change of character state in a given branch of the tree, be it the change from one nucleotide base to another, amino acids, or the color of an animal's iris. The fewer transformations, the shorter the tree, and therefore the more parsimonious. In this method, what programs do is to investigate as many alternative topologies as possible (or all if their array has less than 25 terminals; see more details below) given their character array. Each will be measured, and the shorter (optimal) trees will be retained as the most parsimonious result.
Answer:
c.
