Three adaptations in insects are:-
A) Small size- Their small size enables them to be moved easily by wind or water.
B) Exoskeleton- Diversity of insects also is enhanced by the hard exoskeleton that protects them and keep them from drying out in deserts and other dry areas.
C) Reproductive capacity- The reproductive capacity of insects ensures that they are successful in any areas they inhabit.
All galaxies have a dense core of stars. Spiral galaxies, however, have arms that are often visible. There are two kinds of spiral galaxies: barred, where there appears to be a line running from arm to arm through the core, and <span>ordinary, where there is no bar. @Badbunnyhunny</span>

Answer:
The cell will swell
Explanation:
water will move forward on the solution into the cell via semi-permeable membrane by osmosis.
Atrial natriuretic peptide released by certain atrial cells
in response to rising BP or volume, causes systemic vasodilation and inhibits
renin, aldosterone, and ADH release. Hence, it enhances Na+ and water
excretion, reducing BP and bv. Falling
arterial pressure promotes vasoconstriction and conserves Na+ and water.
