When plants make flowers, gene A is expressedin whorls 1 and 2, gene B is expressed in whorls 2 and 3 and gene C in whorls 3 and
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.

Why are 4 H+ needed for every ATP synthesized and exported by mitochondria, even though only 3 H+ need to be translocated by the
kykrilka [37]

Answer: One H⁺ ion ie required in converting ATP and inorganic phosphate to ATP

Explanation:During oxidative phosphorylation, high energy electrons released by hydrogen carriers are shuttled through the electron transport chain. The released energy is used to translocate 3 H+ ions from the matrix, creating an proton motive force, which will cause 1 H+ ion to move down the electrochemical gradient and diffuse back into the matrix (chemiosmosis) which is facilitated by ATP synthase. As the H+ moves through the ATP synthase this triggers the molecular rotation of the enzyme, synthesizing ATP
