DNA a double-helix like structure, containing multiple nucleotide sequences consisting of a phosphate group, a sugar group, a nitrogenous base, and a hydrogen bond between two nucleotides. The hydrogen bond is weak so the double-helix can "unzip" and make RNA. I hope this helps!
The answer is: In recent years, scientists have discovered fossils from long ago that glaciers have hidden
Answer:
- force people to flee their homes
- cause massive earthquakes
- pollute the air with volcanic smoke
- make airplanes fly around ash clouds
Explanation:
The volcanoes can be seen as both creative and disruptive force. The disruptive side of the volcanoes includes numerous things. Because of the big pressure that the volcanoes make on the crust, it is very common that they create earthquakes, some being very strong. They release enormous amounts of gases, ash, and pyroclastic material, resulting in pollution of the air. The gases and ash can stay in the atmosphere for longer period of time, as well as travel over long distance, making the airplanes change their routes and go around them, or stop their flights until the air clears out. The volcanic eruptions themselves are very dangerous for the people, be it calm with lava flows, or with explosive eruptions, the people a forced to flee their homes and leave everything behind in order to save their lives.
Two organisms have the same phenotype but different genotypes when One organism is purebred dominant, and the other organism is heterozygous. So, the correct option is B.
<h3>What do you mean by Genotype?</h3>
Genotype may be defined as the ultimate combination of those alleles which are selected for specific studies.
When an allele is dominant over others, its purebred dominant and heterozygous (hybrid) may have different genotypes but the same phenotype.
Therefore, the correct option for this question is B.
