Answer:
Allopatric speciation occur due to various environmental factors with in the environment.
Explanation:
Speciation occur when two population become so genetically different and the can not interbred to produce fertile off spring. The allopatric speciation occur when population become sepret and diverge over time due to natural selection,genetic drift,and mutation.Genetic drift is the sudden loss of gene from a population which cause the population evolvation. Mutation is also change in the genetic makeup of an individual.Natural selection is the phenomena selected by nature and natural forces are involve to select the trait in a living organism.
Answer:
The correct options are the need to take in oxygen for cellular respiration and the ability to transmit genetic information to an offspring.
Explanation:
Both prokaryotes and eukaryotes use oxygen to carry out aerobic respiration.The major byproduct of aerobic respiration in case of both prokaryotes and eukaryotes is Carbon dioxide(CO2).
Both prokaryotes and eukaryotes have the ability to transmit information to their off springs.Most Eukaryotes carry out the same by sexual reproduction and prokaryotes exhibit the same by binary fission.
Answer: The correct answer is silent mutation . In this type of mutation there is no change in the phenotype of the individual which means there occurs a mutation where two different amino acid codes for the same protein .There are sequences present in the body where a point mutation occurs but the protein formed is still the same .If you will see the genotype you can easily observe that the amino acid sequence is different but the protein formed is same. Example AAA codes for lysine and the amino acid lysine is formed by AAG .
