Answer: Option A.
Polar ice cap in Antarctica.
Explanation:
Scientist drill ice cores from inside the polar ice cap in Antarctica to study variability of climate and differentiate that variability From global climate change. Each layer of the ice tells about weather and what the Earth was like when the first snow fell.
For example, Le grande says that as snow deposits into a growing glacier, the temperature of the air imprints on water molecules.
Icy layers hold particles,aerosols, sea salts, trace elements that were in the atmosphere before and they abide for thousands of years and provide evidence of past events.
The purpose of spindle fiber is to divide the chromosomes in a parental cell to make them into two daughter cells.
Answer:
Electron carriers can be in oxidized or reduced form. NAD+ is the oxidized form of electron carrier. FAD is another example of electron carrier. In regards to analogy, laundry basket with warm laundry.
Explanation:
The electron carriers travels from higher energy or higher electron level to lower energy or lower electron level. The laundry basket which contains warm laundry shows astonishing analogy to the process of electron carriers. The laundry basket here is represented by the electron carrier. The electrons in higher energy level are represented by the warm laundry that have undergone through a process of highly energy generative movements.
