Viruses are not always classified as living cells because they cannot live independently. They rely on a host to provide all resources to live, without a host they are in a dormant, near dead like state. Therefore it has to define a virus as dead or alive as it may or may not have a host.

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.

IrinaK [193]
When atoms in a covalent bond share electrons unequally (one atoms pulls more than the other), the bond is said to be a polar bond is formed when electrons are unequally shared between two atoms. Polar covalent bonding occurs because one atom has a stronger affinity for electrons than the other (yet not enough to pull the electrons away completely and form an ion).
