The anwser is true. Exposure to ultraviolet rays can cause skin cells to produce melanin which darkens the surface of your skin into a suntan.
The order that the nucleotides are arranged in form different "codes" to create traits. RNA in humans is used for transporting, and making the amino acid proteins. 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.
Answer:
a dominant mutation
Explanation:
A monohybrid testcross is a cross-breeding experiment used to determine if an individual exhibiting a dominant phenotype is homo-zygous dominant or heterozygous for a particular phenotypic trait (in this case, wing length). In a monohybrid testcross, a 1:1 phenotypic ratio shows that the dominant parental phenotype was a heterozygote for a single gene that has complete dominance. Moreover, a 3:1 ratio in the F2 is expected of a cross between heterozygous F1 individuals, which means that 75% of individuals with short wings have the dominant allele that masks the expression of the long-wing trait (i.e. the recessive allele).
Answer:
Having bacteria would produce organic molecules and defeat the whole purpose of the experiment which is to make organic molecules from inorganic molecules. The experiment was supposed to demonstrate the formation of the first organic molecules that initiated life on primordial earth. It is believed that lightning powered the formation of the first simple amino acids, like glycine, from the primordial atmosphere which was mainly composed of carbon dioxide and methane.
The individual who did not receive the same credit as Darwin was Alfred Russel Wallace.
<h3>What is the evolution theory?</h3>
The evolution theory is a scientific theory explaining how natural selection may change (evolve) phenotypes across generations.
Alfred Russel Wallace was an evolutionary biologist who understood the importance of natural selection on this process.
In conclusion, Alfred Russel Wallace did not receive the credit as Darwin.
