Karyotype examination needs to be done at metaphase.
In karyotype test, the examiner is trying to find whether the chromosome is having any abnormality. In metaphase, the chromosome is easier to count and observed.
A chemical (<span>colchicine) will be given to make the cells stuck at metaphase. </span>
Answer:
Explanation:
Each residue that is hydrophobic lies on one side forming amphipathic α-helix.This periodicity would allow the formation of hydrophobic surface on one face of the helix thereby allowing it to fold against hydrophobic region of the protein.
Answer:
A slope of 7, representing a speed 7 m/s.
Explanation:
Speed is defined as the distance traveled over time. Mathematically, it's calculated with the equation:
![speed = \frac{distance}{time}](https://tex.z-dn.net/?f=speed%20%3D%20%5Cfrac%7Bdistance%7D%7Btime%7D)
Slope of a graph is the rate at which the y and x axis change together, the "rise over the run." Slope can be simply calculated using this equation:
![slope = \frac{x_{2} - x_{1}}{y_{2} - y_{1}}](https://tex.z-dn.net/?f=slope%20%3D%20%5Cfrac%7Bx_%7B2%7D%20-%20x_%7B1%7D%7D%7By_%7B2%7D%20-%20y_%7B1%7D%7D)
Therefore, when graphing distance versus time, the change in distance is divided by the change in time to find the slope. This is the same as speed.
