1. How will the location of sun on the diagram change when the sun becomes a red gant
it will move to the cooler and dimmer part of the diagram.
It will move to the cooler and brighter part of the diagram.
it will move to the hotter and dimmer part of the diagram
I will move to the cooler part of the diagram with the same luminosity

The sun will move to the cooler and brighter part of the diagram.

Explanation:

When the sun becomes a red giant, it means it is fusing hydrogen in its outer shells and the inner core has exhausted its hydrogen fuel. Because the sun has a  smaller mass relative to other big stars, its does not have enough gravity to fuse helium. Therefore, the radiant and thermal pressure from the contraction of the core overpowers the gravitational pull causing the outer shells to grow and move away from the core. The general temperatures of the sun slightly decreases (hence is cooler) but luminosity (brightness) increases because of the increase in star size.  The star grows to over 250 time is current size 'swallowing' the earth too.

answer; i believe the correct answer is (replication is not conservative);

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.
