Answer: THEY ARE INVOLVED IN THE DISASSEMBLY OF THE NUCLEAR ENVELOPE
Explanation: The disassembly of the nuclear envelope is triggered by the cyclin‐dependent kinase at the onset of mitosis. At this point, Integral nuclear membrane proteins diffuse/move into the endoplasmic reticulum (ER) after nuclear envelope breakdown. The nuclear envelope reassembles around compact chromosome mass at late anaphase/telophase and the chromosomes condenses and become visible.
Answer:
The Marburg virus wasn't mutating this early on, therefore the Coronavirus is much more deadlier and almost impossible to get a cure for, due to the rapid change in pathogens!
Answer:
Filtration, Reabsorption, Secretion: The Three Steps of Urine Formation. The kidneys filter unwanted substances from the blood and produce urine to excrete them. There are three main steps of urine formation: glomerular filtration, reabsorption, and secretion.
Explanation:
There is only one measure of "evolutionary success": having more offspring. A "useful" trait gets conserved and propagated by the simple virtue of there being more next-generation individuals carrying it and particular genetic feature "encoding" it. That's all there is to it.
One can view this as genes "wishing" to create phenotypic features that would propagate them (as in "Selfish Gene"), or as competition between individuals, or groups, or populations. But those are all metaphors making it easier to understand the same underlying phenomenon: random change and environmental pressure which makes the carrier more or less successful at reproduction.
You will sometimes hear the term "evolutionary successful species" applied to one that spread out of its original niche, or "evolutionary successful adaptation" for one that spread quickly through population (like us or our lactase persistence mutation), but, again, that's the same thing.
