Answer:
The answer is E.
Explanation:
An anabolic reaction is one that involves the building of complex substances from simple ones and it uses up energy. Photosynthesis is an anabolic reaction because It requires energy.
A catabolic reaction is one that involves the breakdown of complex substances into simpler ones and in the process energy is released. Cellular respiration is catabolic because energy is released during this process.
The gel should be placed in the correct direction so that the DNA bands can move.
- DNA is negatively charged due to the presence of phosphate groups, so it can only move towards the positively charged anode, otherwise, it will not move.
- So, when gel electrophoresis is done the side of the gel where the wells have been created and DNA samples have been loaded is placed at the side of the cathode, whereas the other side is connected to the anode.
- When the current flows, the DNA fragments also move from negatively charged cathode to positively charged anode as per their mass and size.

In prophase I of meiosis, homologous chromosomes form tetrads.
High frequency, short / small wavelength
Meiosis has two rounds of genetic separation and cellular division while mitosis only has one of each. In meiosis homologous chromosomes separate leading to daughter cells that are not genetically identical. In mitosis the daughter cells are identical to the parent as well as to each other.
