Answer:

the time that cell spend in prophase is 30 minutes

Explanation:

The computation is shown below:

= Number of cell ÷ sample

= 25 ÷ 100

= 1 ÷ 4

Now it takes two hours

So,

= 1 ÷ 4 × 2 hours

= 0.5

This 0.5 represent the 30 minutes

Hence, the time that cell spend in prophase is 30 minutes

lord [1]
The correct answer is to obtain a thorough history of the seizure type and incidence. The patient is already taking phenytoin for 10 years so there must be an underlying seizure disorder. The type of the seizure (absence, tonic-clonic, etc.) should be characterized as this will affect the management of the patient. Placing an airway in a patient without respiratory distress is unnecessary and may even produce traumatic injury to the patient. Asking to remove dentures and eyeglasses is also unnecessary.
