Answer:
B.Active transport, because energy is being used to move molecules against the concentration gradient
Explanation:
Substances move in and out of living cells through various transport means. Some substances move passively (without energy) while others move actively (with energy). Active transport of substances involves the movement of molecules against the concentration gradient. 
Active transport moves against concentration gradient in the sense that the movement occurs from a region which is less concentrated to one which is more concentrated, hence, energy input in form of ATP is required for such transport to occur. This is the case of the cellular transport in the diagram. Therefore, it is an ACTIVE TRANSPORT because energy input (ATP) is required.
Note, Osmosis and facilitated diffusion are types of passive transport that requires no energy to occur.
 
        
             
        
        
        
Atropine would block the receptor called muscarinic acetylcholine receptors present in the eye.
Atropine is the Anticholinergic agent which is also known as parasympatholytics. The activity of neurotransmitters at the receptors leads to pupil constriction. 
Atropine is used to block these receptors that allow the pupillary muscles to relax. This causes the dilation of the pupil. 
Atropine is the mydriatics that is used for pupillary dilation to conduct a detailed examination of eye diseases. 
without this medication, the pupil will only dilate in the darkness. However, doctors cannot examine the eye problems as there is darkness as they need light for checkups.

The cell cycle or cell-division cycle is the series of events that take place in a cell leading to its division and duplication of its DNA (DNA replication) to produce two daughter cells. In bacteria, which lack a cell nucleus, the cell cycle is divided into the B, C, and D periods. The B period extends from the end of cell division to the beginning of DNA replication.

i will have another one but i need the five points to make the question so ill tell yall in a comment in this answer
 
        
                    
             
        
        
        
Answer:
2) End Triassic
Explanation:
End Triassic extinction occurred 201 million years ago. It was caused by the rifting of super continent Pangea. Pangea started to break and drift apart. When North america started to separate from Africa, volcanic activity increased. Lava and a large amount of gas was released into the atmosphere specially carbon dioxide. This led to global warming like condition which ultimately caused extinction of a large number of species.
