<span>Protected left turns are areas for turning that are controlled by a traffic signal or traffic sign. The traffic sign may be light.</span>
A green light means you may turn left. while <span>a red light means you must stop. Opposite to this, non protected left turns are not controlled by traffic sign.

Answer:
Active transport
Explanation:
The molecules are moving from a low concentration to a high concentration across a cell membrane via a protein. ATP is used in this reaction.
We know it cannot be diffusion, facilitated diffusion, passive transport, or osmosis, because these are all passive processes. In the picture, the molecules are moving against their concentration gradient and uses energy.
It cannot be endocytosis or exocytosis, as there are no vesicles.
Active transport is the movement of molecules from a low concentration to a high concentration across a cell membrane against their concentration gradient. ATP is used to supply the energy for this process.
Answer:
mRNA is produced in the nucleus.
Answer:
It causes global warming due to emission of carbondioxide gas.
Explanation:
Volcanic eruptions change the flow of energy on earth by emitting gases such as carbondioxide and sulfur dioxide gases. Volcanic gases like sulfur dioxide is responsible for global cooling by reflecting solar radiation back to the space, while on the other hand, carbon dioxide emitted from volcanoes, has the ability to promote global warming by blocking solar radiation. If the amount of carbondioxide gas is higher as compared to sulfur dioxide gas so global warming occurs.
Answer:
The flu is caused by influenza viruses that infect the nose, throat, and lungs. These viruses spread when people with flu cough, sneeze or talk, sending droplets with the virus into the air and potentially into the mouths or noses of people who are nearby.
