Answer:
Biennial
Explanation:
Biennial are those crops which takes two years to complete its life cycle i. e. vegetative stage and reproductive stage. First stage is the vegetative stage in which vegetative parts such as roots, stems, leaves and branches are formed. Second stage is reproductive stage in which flowers formed first and after that seeds are produced due to fertilization. Seeds are the babies of plants.

Answer:
The creation of the limbs is carried out by AER and ZVP. AER stands for apical ectodermal ridge and ZVP stands for polarising activity line.
Explanation:
- AER is responsible for the developmental progression in the distal to the anterior region and the ZVP is liable for the progressive advancement in the posterior to a backward region.
- AER and ZVP are interconnected on one another in the secretion of a sonic hedgehog, which eventually assists throughout the hox speech to promote the growth of the arm.
- The hypothesis that the new short-arm gene inhibits the effect of FGF (fibroblast growth factors) on AER can be tested and use a template of cultured cells.
- The AER may be disrupted in the model and the impact of the gene encoding on FGFs may be examined. If in the existence of a viral vector, the role of the FGFs is to trigger correct growth, then the hypothesis is incorrect, or else the hypothesis is right. The FGF8 is by far the most powerful of all as the result.
