Answer:
each of the two daughter DNA molecules contains one strand from the original DNA molecule and one newly synthesized strand.
Explanation:
DNA replication is a semi-conservative process. The two parental DNA strands are separated from each other by the action of helicases. The separated DNA strands serve as the template. Primase enzyme forms primers which are elongated by DNA polymerase enzymes. These enzymes elongate the primer by the addition of deoxynucleotides complementary to the sequence of the template DNA strand.
Therefore, DNA replication forms two DNA double helices from one parental DNA molecule. Each of the daughter DNA molecules contains one parental DNA strand and one newly formed DNA strand making the process semi-conservative.
Answer:
Explanation:
Homeostasis and Cell Transport Homeostasis is the process by which cells maintain the internal conditions that they need to support life. This can be generalized to the heat that our bodies generate to keep us warm and support chemical reactions or the microscopic movements of molecules across cell membranes.
Answer: Electrons positioned closer to the nucleus have a greater attraction to the protons and are more likely to be discharged from the atom than electrons farther away.
Explanation: The electrons being negatively charged repel each other due to like charges. The protons being positively charged are attracted towards the negatively charged electrons.
The electrons which are near to nucleus are more tightly held by the protons and thus are more difficult to remove from the atom. The electrons which are far from the nucleus are less tightly held and are easily removed from the atom.
Answer:
Bioremediation
Explanation:
Bioremediation means using living organisms to detoxify polluted ecosystems.
Answer:
Anthropogenic biomes, also known as anthromes, human biomes or intensive land-use biome, describe the terrestrial biosphere in its contemporary, human-altered form using global ecosystem units defined by global patterns of sustained direct human interaction with ecosystems.
