A scientist is using a microscope to examine a mature red blood cell. The scientist notices that the red blood cell does not have a nucleus. Describe the function of red blood cells in the human body. Then, explain how not having a nucleus helps mature red blood cells perform their function.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.

her next move would be to use agarose gel electrophoresis to separate the dna molecules of varying length and create a dna fingerprint.
