(a) Total power of magnification 100x because ocular lens is 10x magnification maultiplied by 10x objective lens.
(b) Widht of the onion cell can be calculated as follows:
If the number of units observed for an onion cell through ocular micrometer (10x) under microscope is 'A'.
Then, the widht of the cell will become = A X 9.5 (Calibration factor of ocular unit and total power fo magnification is 100x)
So, for example if the observation through ocular micrometer is 13, then the widht of the onion cell will be = 13 X 9.5 = 123.5 μm
For the Y-linked gene, there is only one mode of inheritance. For X-linked dominant and recessive genes, there are two modes of inheritance. For the autosomal dominant and recessive, it depends on the origin of the genes. For homozygous dominant and homozygous recessive parents, there is only one mode of inheritance.
In strike-slip faulting, the intermediate stress is vertical. The largest and smallest stresses are horizontal. The shear fracture (fault) makes an angle of less than 45 degrees with the major (most compressive) principalstress direction, in this case again the horizontal. There is no vertical movement. ) Hope this helps
B if they cant find any population drops making it a limiting factor
hi!! i think the answer to your question is B. fertilization!!
i hope this helps, good luck!! <3
