The controversy surrounding the nucleic acids and proteins, regarding which one of them was formed first is the most popular controversy in the biology world today. The nucleic acids stores and the genetic information. The proteins essential for all the life processes are encoded by the genes formed of the nucleic acids (DNA and RNA). But proteins (enzymes) are required for the formation of proteins from the genes. The inter-dependency of the nucleic acids and proteins on each other possesses a dilemma to the question 'which of them arrived first'.
The answer to this dilemma was answered when it was discovered that RNA was capable of not only carrying the genetic information, but also acting as catalyst to the chemical reaction. This finding supported the notion that the RNA evolved first serving the purpose of both the nucleic acids and emzymes.
Answer: The vascular plants are set apart in two main ways: Vascular plants have vascular tissues, which circulate resources through the plant. This feature allows vascular plants to grow to a larger size than non-vascular plants, which lack these specialized conducting tissues and are therefore restricted to relatively small sizes.
Answer:
in a certain population of red squirrele, a mutation causes several squirrels to
be bom with darker coats. These coats make the squirrels nearly inweible
when they are foraging on the forest floor
, According to the theory of evolution by natural selection, what is likely to happen to this trait after several generations?
After several generations, this trait is likely to be much more common because individuals with the trait will have a greater chance of passing it on to their offspring,
Explanation:
It would later turn to what is termed as germline mutation which are mutations passed from parent to offspring, as time progresses the trait would be more and increases the chance of being transferred to their offspring
Answer:
28 day orbit around Earth.
Explanation:
This is called the Lunar phase. The lunar phase or phase of the Moon is the shape of the directly sunlit portion of the Moon as viewed from Earth.
