Considering that we are all made up of the same 4 nucleotides in our DNA, the same 4 nucleotides in our RNA, and the same 20 amino acids in our proteins, why are we so different from each other?

Answers

The order that the nucleotide are arranged in form different 'codes' to create traits.RNA in human is used for transporting,and making the amino acids proteins.

The order of amino acid proteins also changes the polypeptide formed, changes more traits and characteristics.

Nucleotide in DNA contains four different nitrogenous bases-

Thymine
Cytosine
Adenine
Guanine

Pyrimidines: Cytosine and thymine each have a single six-member ring.

Purines:Guanine and adenine each have a double ring made up of a five-atom ring attached by one side to a six atom ring.

Therefore,they are different, due to nucleotide of our DNA contains four different nitrogenous bases.

The order of amino acid proteins also changes the polypeptide formed, and changes more traits, and characteristics. Basically, it's like reading a book. Each book is made up of the same 26 letters, but their all arranged in different orders. You can find the some of the same words in another book, but no two books are exactly alike. All the letters and words are arranged in different ways, even though other books have the same letters and words.

Which includes the physical characteristics of an organism? gene allele genotype phenotype

Answers

The physical characteristics are the attributes that are visible on the outside. They are included in the phenotype of the organism. Thus, option d is correct.

What is phenotype?

A phenotype is an observable characteristic that can be in the form of morphology, structure, appearance, and behavior. The phenotypical traits are defined and caused by the expression of the genotypical traits that are controlled by the inherited genes.

The phenotype includes hair color, eye color, height, weight, blood cells, earlobes, freckles, etc. It differs from a genotype as it is not a genetic code but an expressed or visible characteristic. It is controlled by the expression of genes and environmental factors.

Therefore, option d. the phenotype is the physical characteristics of an organism.

If the earth's differentiation were any different, it may have affected its gravitational pull and . Both of these factors were essential to creating our atmosphere.

Answers

If the Earth's differentiation were any different, it may have affected its gravitational pull and tectonic activity. First, it must be clarified that differentiation refers to the geological process that resulted in the Earth's interior structure. This means that tectonic activity such as volcanic activity are also essential to creating our atmosphere by participating in the various atmospheric cycles.

The chemical process for respiration

Answers

In a scientific sense, a chemical process is a method or means of somehow changing one or more chemicals or chemical compounds. Such a chemical process can occur by itself or be caused by an outside force, and involves a chemical reaction of some sort.

A group of paleobiologists were studying sedimentary rocks in the Rocky Mountains of North America. What order of organisms would they find in the layers of these sedimentary rocks? All organisms are arranged randomly in the layers of sedimentary rocks./ Newest organisms are at the bottom and the oldest organism is in the top-most layer of the sedimentary rocks. /Oldest organisms are at the bottom and the newest organism is in the top-most layer of the sedimentary rocks.

Answers

Sedimentary rocks are rocks that are formed by the deposition of the weathered remains of other rocks. These are mixed sand, mud and pebbles that are laid down in layers and even fossils are found in these rocks. The order of organisms that they would find in the layers of these sedimentary rocks is, oldest organisms are at the bottom and the newest organisms are in the topmost layer of the sedimentary rocks.

The order of organisms that they would find in the layers of these sedimentary rocks is; Oldest organisms are at the bottom and the newest organism is in the top-most layer of the sedimentary rocks.

Sedimentary rocks are rocks that are made by the deposition and compression of other rocks or pieces of organic matter (dead plants and animals). According to the law of superposition which states that in a sequence of undisturbed sedimentary layers, the youngest layer is always at the top while the oldest layer is always at the bottom of the sequence. From the question, the organisms are components of the rocks. The oldest organisms will be found at the bottom layer of the sedimentary rocks while the newest organisms are in the topmost layer of the sedimentary rocks.
