A. It goes back into the soil.

Explanation: Plant body is made of nitrogen elements which is the basic structural component of amino acids and enzymes present in the plants body. When the plants die, decomposers such as bacteria and fungi etc feed on these dead bodies and broken down into simpler substances. This nitrogen is converted into ammonia and mixes with the soil. This ammonia is again used by the plants through roots.

gametes or germ cells are haploid cells (example: sperm and ova) containing only one set (or n) number of chromosomes and autosomal or somatic cells are diploid cells containing 2n number of chromosomes.

answers are:

lysogenic     viral dna merges with host cell dna

lysogenic     no symptoms

lytic               viral dna takes over

lysogenic     virus does not destroy host cell

lytic               virus destroys host cell

lytic               induces symptoms of viral infection

lysogenic       cell reproduces and spreads provirus
