please mark this answer as brainlest

Answer 2

The solute-like solids can dissolve in the solvent through the dissolution process. Powders have more surface area that permits more dissolution.

What is surface area?

The surface area is the amount of space covered or occupied by an object. It is directly dependent on the solubility and increases with an increase in the solubility.

The surface area of the powder is more compared to the solid pill and hence, the solubility of the scoop of powder is more than the pill.

Therefore, powder dissolves faster because option A. has more surface area.

The answer is probably tt

Well for parent 1 and parent 2 ( 1st parent of 2 ), parent 1 shows T so it forms Tt

Parent 1 and 2 ( 2nd parent of 2 ) ( parent 1 also has T and parent 2 has t ) so it forms Tt

Parent 1 ( 2nd parent of 1 ) and parent 2 has t and parent 1 is  normal which forms tt

So that leaves 2nd parent 1 and parent 2

tt i think is the correct if you get it wrong I’m sorry I’m trying my best
