B, cold with a high salt content, I believe.
Since density is mass divided by volume, adding salt would increase mass.
Temperature is related to kinetic energy and the distance between molecules/atoms of a substance. The hotter the substance, the more distance there is between particles.
Generally cold water is more dense. Hope i helped :D
Answer:
none of the above
Explanation:
input would be carbon dioxide and output would be oxygen
All the steps of GPCR signaling would be prevented in the presence of a beta-blocker drug.
<h3>What is Beta-blocker?</h3>
Beta-blocker may be defined as a kind of medication that chokes the activity of substances, such as adrenaline, on nerve cells and provokes blood vessels to relax and dilate.
Adrenergic receptors choke the attachment of catecholamine that is epinephrine to the G-protein. G-protein activates adenylyl cyclase which in turn activates protein kinase A.
But when the beta-blocker drug is subjected to this pathway, it blocks the attachment of the hormone to their receptors, hence none of the pathway or steps would be carried forward. This is because signaling is not initiated.
Therefore, all the steps of GPCR signaling would be prevented in the presence of a beta-blocker drug.

The event was volcanic eruption.
The second largest volcanic eruption took place in June 1991. The volcanic eruption took place in the Mount Pinatubo (a chain of volcanoes along the Luzon arc) on the island of Luzon in the Philippines. After the millions of tons of sulfur dioxide were discharged into the atmosphere, resulting in a decrease in the temperature worldwide over the next few year.
The carbon cycle is a cycle the reuses carbon ( Carbon is never used up )it is constantly being reused and added to but never decreases.
