Answer:
One of the RNA molecules has experienced gene duplication as the result of translocation.
Explanation:
Translocation and duplication are some of the structural abnormalities in the chromosomes that may even cause certain genetic disorders. Duplication is the presence of a genetic segment for more than one time in the chromosome. The repeated genetic segments are mostly present in the tandem pattern. When a chromosome fragment breaks off and attaches to a non-homologous chromosome, it is called translocation. It leads to the deletion of a genetic segment in one chromosome and duplication in the other.
According to the given information, a genetic segment bearing two genes is detached from one RNA and gets attached to the other RNA molecule of the HIV genome. Therefore, the RNA molecule has undergone translocation and has lost a genetic segment while the other has gained a genetic segment (duplication) due to translocation.

That would be the chloroplast.
Answer:
1. Apoplastic
2. Symplastic
3. Symplastic
4. Apoplastic
Explanation:
The interconnected porous cell walls of plant cells make apoplast along which water is allowed to move freely. Symplast refers to the path made up of interconnected cytoplasm of many plant cells connected by plasmodesmata. Therefore, water and dissolved minerals enter the root cortex from the epidermis in the solution can move through symplast and apoplast till endodermis.
Water and dissolved minerals present in the cytoplasm of cortical cells move from one cell to next via plasmodesmata (the symplast) while the ones present in their cell walls and intercellular space move through apoplast. The presence of casparian strips in the endodermal cell wall does not allow the movement of water and minerals through the apoplast.
