Answer:
An organism's DNA affects how it looks, how it behaves, and its physiology. So a change in an organism's DNA can cause changes in all aspects of its life. Mutations are essential to evolution; they are the raw material of genetic variation. Without modification, growth could not occur. i hope this help
Explanation:
Every young corn plant will have the male straw-tassels at the top, the male part, and the silk tassels lower of the plant on the developing corn, the female part. The developing corn has ovules in its ears. The pollen from the straw-tassels will pollinate the silk tassels. The silk are the stigma and style of the female flower. When the pollen travels down the style and fertilizes the ovules, a corn(the seed) develops on the cob.
Each silk represents a corn seed. If particular silks are not pollinated, that corn will not be full of corn
The human body has 3.2 billion nucleotide pairs so the total length of the double helix in a human body cell is about 2 meters.
<h3>Two meters of DNA?</h3>
DNA from a human cell is almost two meters long. To facilitate the organization of DNA within the cell nucleus, it is divided into elements called chromosomes.
With this information, we can conclude that the human body has 3.2 billion nucleotide pairs, so the total length of the double helix in a human body cell is about 2 meters.
