lana [24]

Answer: No

Can the change in cyclin concentration during mitosis be explained by the fact that the cell divides in two and thus divides the material in the cell into two smaller volumes?

Explanation: The cyclin concentration is not halved but degraded during mitosis.

There is an increase in cyclin concentrations at interphase. These changes are caused by the presence of Cyclin Dependent Kinase (CDK) complexes. CDK being a substrate of cyclin catalyses cyclin, thereby increasing its concentration. During mitosis, cyclins are destroyed, signifying the end of mitosis and cytokinesis.

Without this process, it will be impossible for the cell to exit mitosis.

A compact disc (CD) is read from the bottom by a semiconductor laser beam with a wavelength of 790 nm that passes through a plas
Ad libitum [116K]

Answer:

The value is   t  = 110 nm

Explanation:

From the question we are told that  

   The wavelength of the beam is \lambda  =  790 \  nm  =  790 *10^{-9} \  m

   The refractive index is  n_r  =  1.80

Generally from the condition for destructive interference  the depth  of the pit  is mathematically represented as

     t  = [ m  + \frac{1}{2} ] *  \frac{\lambda}{n_r}  *  \frac{1}{2}

Here m which is the order of the fringe is zero because both beams cancel out

So

       t  = [ 0  + \frac{1}{2} ] *  \frac{790 *10^{-9}}{ 1.80}  *  \frac{1}{2}

=>     t  = 110 *10^{-9} \  m

=>     t  = 110 nm
