Chemicals can make mutations by a number of mechanisms. Base
analogs are incorporated into DNA and mostly pair with the wrong base.
Alkylating agents, deaminating chemicals, hydroxylamine, and oxidative radicals
change the structure of DNA bases, thus altering their pairing properties.
Introducing agents wedge between the bases and cause single-base insertions and
deletions in replication.
Answer:
Cells are so little, so they can maximize their ratio of surface area to volume.
Explanation:
Smaller cells have a higher ratio which allows more molecules and ions to move across the cell membrane per unit of cytoplasmic volume. Cells are so small because they need to be able to get the nutrients in and the waste out quickly.
The "Cranes" is a short story book written by Hwang Sunwon. The story is set in Korea during the Korean War and focuses on two childhood friends, Songsam and Tokchae, who are on opposite sides during the war. Songsam has two flashbacks of his childhood memories with his friend Tokchae, where he remembers how they used to climb the trees and catch cranes. These flashbacks act as a reminder of the times he had spent with his friend and the importance of this friendship. As a result, these memories motivate him to let Tokchae free.
