Answer:
A. nucleus
Explanation:
The cell nucleus is a structure present in eukaryotic cells, being, precisely, the main characteristic that differentiates them from prokaryotic cells, those that have the nucleoid genetic material. It is in the nucleus that this is the instructions for cells to differentiate and different types of tissues.
To facilitate understanding, an analogy is possible. Let's say the cells are industries, each department within the company is responsible for performing a specific function. In this case, these departments would be organelles, such as the Golgi complex, mitochondria, among others. The core, in this comparison, would be the management or administration sector. This is because it is exactly in the nuclear region that the genetic information that coordinates and commands cellular functions is present.
Prokaryotes are the same as bacteria. So the answer is c., bacteria.
It is called a electron. A electron has a negative charge in atoms.

The relative densities of the water as solid and liquid differ from the subsequent densities of the other substances. The density of the solid form of water is less than the density of water in its liquid form. However, majority of other substances increases in density when they solidify. This is the reason that the ice (which is the solid form of water) floats on water (liquid form).
Hence, the correct answer is 'Water's solid form is less dense than solid form while the case in opposite in other substances'.
Modern radio tuners use a superheterodyne receiver with tuning selected by adjustment of the frequency of a local oscillator. This system shifts the radio frequency of interest to a fixed frequency so that it can be tuned with fixed-frequency band-pass filter
