Answer: The answer is A
During mitosis (nuclear division), the chromosomes condense, the nuclear envelope of most cells breaks down, the cytoskeleton reorganizes to form the mitotic spindle, and the chromosomes move to opposite poles. Chromosome segregation is then usually followed by cell division (cytokinesis).
The nucleus is important to a living cell because <span> it serves the function of information storage, retrieval and duplication of genetic information. It is a double membrane‐bound organelle that harbours the genetic material in the form of chromatin.</span>
A pansy is a dicot as the plant has flower parts in multiples of 4 or 5 and the major leaf veins are reticulated.
Answer:

Explanation:
Let the frequency ,

Now the unit of frequency is hertz = s⁻¹ = T⁻¹ where T is time, tension T = kgm/s² = MLT⁻¹ and linear density m = kg/m = ML⁻¹.
So,
![T^{-1} = L^{x}[MLT^{-2} ]^{y}[ML^{-1} ]^{z}\\](https://tex.z-dn.net/?f=T%5E%7B-1%7D%20%20%3D%20L%5E%7Bx%7D%5BMLT%5E%7B-2%7D%20%5D%5E%7By%7D%5BML%5E%7B-1%7D%20%5D%5E%7Bz%7D%5C%5C)
collecting the like bases, we have
![T^{-1} = [L^{x + y -z}][M^{y + z} ][T^{-2y} ] \\L^{0} M^{0} T^{-1} = [L^{x + y -z}][M^{y + z} ][T^{-2y} ]](https://tex.z-dn.net/?f=T%5E%7B-1%7D%20%3D%20%5BL%5E%7Bx%20%2B%20y%20-z%7D%5D%5BM%5E%7By%20%2B%20z%7D%20%5D%5BT%5E%7B-2y%7D%20%5D%20%5C%5CL%5E%7B0%7D%20M%5E%7B0%7D%20T%5E%7B-1%7D%20%3D%20%5BL%5E%7Bx%20%2B%20y%20-z%7D%5D%5BM%5E%7By%20%2B%20z%7D%20%5D%5BT%5E%7B-2y%7D%20%5D)
Equating powers on both sides, we have
x + y - z = 0 (1)
y + z = 0 (2)
-2y = -1 (3)
From (3), y = 1/2
From (2), z = -y = -1/2
Substituting y and z into (1), we have
x + y - z = 0
x + 1/2 - (-1/2) = 0
x + 1/2 + 1/2 = 0
x + 1 = 0
x = -1
So,
