2. Some mutant corn plants start seed germination while the kernels are still on the cob, a condition known as 'vivipary'. Researchers found that the mutants can't regulate abscisic acid (ABA) and can be of two types: one that can overcome this condition by exogenous application of ABA and another type that cannot. Explain why ABA absence would promote vivipary and how the two types could be explained in terms of gene expression? In 2010 NASA cont Arabidoncic coods to the IntornationaIS.

3. In 2010, NASA sent Arabidopsis seeds to the International Space station and grew them under zero gravity conditions. To their
surprise, the plants germinated and developed shoot and root systems growing in opposite directions and the root showed patterns of
normal root growth behavior. What might this suggest about gravity's role in plant seed germination and develonment and how do
