Uni cellular organisms remove their waste directly through the cell membrane by the process of diffusion while multi cellular organisms remove waste from excretion
Because an organism with a genetic variation may have better chances of breeding and passing on that trait if the trait is beneficial to the survival of that organism. This leads to that trait being passed on and becoming wide-spread over generations of reproduction; natural selection.
"Anaphase I" is the phase of meiosis among the choices given in the question that tetrads are separated as homologous chromosomes are pulled to opposite poles of the cell. The correct option among all the options that are given in the question is the second option, or option B.
I hope it helps you!
<h2>Succession </h2>
Explanation:
Succession is a phenomenon in which older communities are replaced by advanced and newer communities
- Primary succession is the one in which succession occurs at newer area where none of the community previously evolved
- Secondary succession is the one in which the substrate has already been prepared by the older communities so that the newer community which will arrive grow faster that is why secondary succession has faster pace
- Glacial retreats leave behind nothing but bare rock as they retreat from an area, leaving barren land from which primary succession can occur which enables scientist to study plant succession
