I believe the answer would be sedimentary rocks.
Answer:
Gamete C
Explanation:
During the formation of gametes, the DNA is first duplicated, and 2 separate cell divisions take place to make a haploid cell.
In the first division, the homologous chromosomes are separated
Before the first cell division, the homologous chromosomes align in the centre. In this cell, the light green and dark green chromosomes align, as do the light purple and dark purple chromosomes. These are then separated into 2 different cells, 1 gets either the light or dark green chromosome and either the light purple and dark purple chromosome. The other cell also gets either light green or dark green and light purple or dark purple.
Then, a second division takes place that separates the sister chromatids to produce what we see in the gametes A, B, C, and D.
The only one that is not possible in a healthy cell is C, because it has not received any of the green chromosomes and instead has two homologous purples.
The answer is; detecting stars that are behind nebulae that would normally block out other stars
Radio waves have large frequencies unlike the other waves of the electromagnetic spectrum. Due to their large wavelength, they are much larger than the size of an atom hence cannot be blocked or deflected by atomic nuclei. This is unlike gamma rays (and other short wavelength electromagnetic radiation) that are smaller than atoms and easily blocked and deflected by atomic nuclei. Such radiations are extremely attenuated when they pass the through nebula cloud. Radio waves hence overcome this challenge.
