Answer:
Each objective lens has a different magnification. Multiply the magnification of the eyepiece by the magnification of the objective lens to produce total magnification. For example, a 10X ocular lens and a 40X objective lens will produce a total magnification of 400X (10 x 40 = 400).
Answer:
Option C, ppAa is indicative of white axial flowers.
Explanation:
It is given that Purple color (P) is dominant over white color (p). Thus in order to have a flower of white color , the flower must be homozygous recessive with an allele pair having two recessive alleles.
Similarly, Axial (A) is dominant over terminal (a) flower. Thus, a flower can be axial in two cases -
a) when both the alleles are same i.e AA
or
b) when one allele is A and the other one is a i.e Aa
Considering the above cases, all possible allele combination that will produce white axial flower are as follows -
ppAA, ppAa
Thus, option C is correct
Cyclins
are the chemicals that regulate the cell cycle. Cyclins work by regulating the timing
of the cell cycle in eukaryotic cell. Cyclins activates cyclin dependent
kinases (CDKs) (an enzyme that works by adding <span>negatively charged phosphate groups to other
molecules in a process called phosphorylation) by binding to it to form a cyclin-Cdk
complex. This complex then functions by acting as a signal to the cell to move
to the next cell cycle phase. At the end of the event, the cyclin is degraded, Cdk
is deactivated, therefore signaling exit from a specific phase.</span>
