zmey [24]3 years ago

Answer:

Meiosis

Explanation:

Gene recombination refers to the mixture of genes from different individuals that occurs during sexual reproduction. Gene recombination is responsible for mixing between genes, which results in genetic variation in a bacterial population.

Genetic variability in a bacterial population occurs through three types of mechanisms: transformation, conjugation and transduction. However this genetic variation does not occur through Meiosis.

Transformation is the incorporation of free DNA by the bacterial cell. Conjugation is the process of transferring DNA from one bacterium to another, involving contact between the two cells. Transduction is the transfer of genetic material between cells, mediated by bacteriophages.

Sophie [7]

Answer:

C.  Cnidarian tentacles have stinging cells, but Bryozoan tentacles are covered with cilia.

Explanation:

Cnidaria and Bryozoan, both teh phylum are classified under kingdom Animalia that contain aquatic animals found both in freshwater and marine environments.

They both use tentacles for feeding but there is diffference between there tentacles and feeding process.

Cnidarians tentacles are conist of stinging cells in the tips, which are called cnidocytes and a coiled thread-like stinger, called nematocyst. These stinging cells and nematocyst helps to capture and subdue prey. They feed over plankton or animals larger then them.

Bryozoan tentacles are covered with cilia and form an "O" or "U" shaped fold called lophophore, which helps to feed by sweeping the surrounding water. They generally feed on plankton, nudibranchs (sea slugs) and sea spiders.

Hence, the correct option is C.
