Sati [7]

Answer:

The correct answer would be option D) no gametes.

Explanation:

The ABC model of the flower was formulated to describe the collection of genetic procedures that determines floral organs in several plants. These species consist of four whorls which are sepals, petals, stamens, and carpels. These whorls are expressed by the expression of a number of genes present in each whorl or verticli.

Gene A is solely responsible for the sepals while the co-expression of A and B genes are responsible for the petals. The identity of the stamens is expressed by B and C and the carpels require C and D genes to be active.

The homozygousity for a normal mutation in gene C will lead to inactive or lack stamens and carpels, which are male and female reproductive organs. These are an important structure for forming gametes.

Thus, the correct answer would be option D) no gametes.

Phantasy [73]
Pinching in of fluids by a unicellular organism is the process of pinocytosis or fluid endocytosis. The cell takes in surrounding fluids, including all of the substances available, without differentiating. It is a non-specific process. The membrane of the unicellular organism elongates, captures the fluid and small vesicles are pinched off intracellularly. These vesicles then are processed by the organelles of the cell.
