Had to look for the options and here is my answer.
Basically, when we say eukaryotes, these are kinds of organisms which consists of cells that has DNA and other organelles that are enclosed by a membrane. In this case, the size of the primary transcript is generally THE SAME LENGTH the gene in the template of the DNA strand. Hope this helps.
I think, materials collided due to strong gravitational forces..
Answer: Natural selection is one of the forces of evolution and the enviroment where the species lives is the selection agent. For example, suppose a mosquitoes population in a environment free from insecticides, in this environment there's a high frequency of non-resistant mosquitoes because the environment is not exerting any pressure on the resistence trait. But when the environment changes and we use a insecticide upon the mosquitoes population, the populations changes because the non-resistant ones die but those resistant survive and beggin to reproduce more effectively. That's natural selection, differences in survival and reproduction between individuals with different phenotypes (traits) and this differences depend of environmental changes.
