Answer:
b. RuBisco
Explanation:
Ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisco) is an enzyme that is used by chloroplasts to convert carbon dioxide from the atmosphere to glucose.
The continental places around the Pacific Ocean have lot of volcanic activity.
Explanation:
The Pacific plate is an oceanic plate. It borders several continental plates. On all sides, the Pacific plate is subducting below the other plates. The subduction zones have resulted in intense geological activity along the boundaries, which are right next to the continental edges. Along the sides of the continents that are having a boundary with the Pacific plate there are lot of volcanoes and earthquakes.
- The boundary between the Pacific plate and the other plates around it makes up the Ring of Fire.
- The Ring of Fire stretches mostly on the edges of the continents, surrounding the Pacific Ocean, and it is the place where most of the volcanoes on Earth are located.
- The formation of volcanoes has influenced the topography of the edges of the continents, and all of them are mountainous along the coastlines.
- All of the volcanic activity and the subduction result in cracking of the crust and adjustment of it, resulting in release of lot of energy, or as we know it - earthquakes.

Chargaff's law and Rosalind Franklin's discoveries
Answer:
If cytokinesis did not occur during mitosis the cytoplasm wouldn't be divided and there wouldn't be two identical daughter cells as a result.
Dopamine
On a biochemical level, cocaine blocks the reabsorption of the neurotransmitter dopamine.
Dopamine is a neurotransmitter (chemical) released by nerve cells in the body to transmit information from one neuron to another. Dopamine performs various important roles in the brain and body. Cocaine, which is a drug of abuse, blocks the reabsorption of dopamine. Cocaine acts by binding to the dopamine transporter, and stops the removal of dopamine from the synapse. Dopamine then increase in the synapse to form an amplified signal to the receiving nerve cells. This result in euphoria (feeling of intense excitement) experienced immediately after administering the drug.
