Which best matches the description with the genetic material? a. nucleotides form a helical structure that is called a gene. (incorrect) b. chromosomes are located in the cytoplasm. c. chromosomes create genes. d. dna is located in the nucleus.

The correct answer is option d, that is, DNA is located in the nucleus.  

DNA that is deoxyribonucleic acid, is a self-replicating substance located in the nucleus and is found in almost all the living species as the prime component of chromosomes. It is considered as the carrier of the genetic information.  

It is a molecule comprising of two chains, which coil around each other to produce a double-helix carrier of the genetic data that is used in the development, growth, reproduction, and functioning of all the known living species and various viruses.  

answer: land bridge theory. land bridge theory held that shifting portions of dry land explained the finding of identical species on different continents. plate tectonic theory eventually eliminated the land bridge theory.

answer: accepted answer: aquatic animals use the oxygen dissolved in water to carry out respiration. since the amount of dissolved oxygen in water is low as compared to the amount of oxygen in the air, therefore the rate of breathing in aquatic animals is much faster than it is in terrestrial animals.
