Answer:
B. The molecules are evenly spread out
Explanation:
salt is completely soluble in water. Na+ will be surrounded by OH- and Cl- will be surrounded by H+
Answer: Option D
Explanation:
None of the characters are true regarding bacteria and archaea. Both of the species have different composition of cell wall. The cell wall of bacteria is made of peptidocglycan and archaea's cell wall lack peptidoglycan.
Bacteria and archaea both are very diverse and are found in variety of environment. They both are found in the extreme environmental conditions.
Archaea and bacteria both are not derived from the eukarya. According to the endosymbiotic relationship the eukaryotes are developed from the prokaryotes.
hence, none of the statements are true.
The genetic variation of organisms has three sources they are mutation, gene flow and sexual reproduction.
Explanation:
Genetic variation are caused by mutation , random mating, random fertilization and recombination between homologous chromosomes during meiosis.
It is a variation in alleles and genes, among the populations. There is a genetic variation within the family of closely- related individuals. If it is a neighborhood there are many families and there is also genetic variation among that group.
An exact genetic copy of the parent organism is produced in asexual reproduction. It only introduces the genetic variation into the population if a random mutation in the organism's DNA is passed on to the offspring.
