During the last stage of mitosis (telophase), the nucleus membrane reappears around the two groups of chromosomes created. Thus forming two nucleoli (two nucleus). I hope this helped, this is what i have from notes i took for that subject last year.
Answer:
a,c,d
Explanation:
Crossing over occcur when genetic material is exchanged between homologous chromosome this leads to formation of new genes that creates diversity.
homologous chromosome assort imdependently i.e seperate from each other leading to the formation of an entirely new gene that creates diversity.
Genetic recombination when gene recombines together to produce a unique type. It occurs between different species.
The precise value is still not known, <span>but it is believed to be between 1.5 and 3 solar </span>masses<span>.
In short, Your Answer would be Option A
Hope this helps!</span>
Answer:
Grade of metamorphism
Explanation:
Gneiss forms at a higher grade of metamophic slate. Slate forms at low metamorphic conditions just about a few temperature and pressure.
From the prolith materials exposed to metamorphic conditions, transformations begins as metamorphic changes begins to take place. First, a sediment is transformed into slate, from slate to phyllite, from phyllite to schist, schist to gneiss, gneiss to migmatite and migmatite goes back to melt. These transformation of sediments is controlled by the nature of the prolith materials and the prevailing metamorphic conditions.
