Answer:

The process of dissolving is endothermic when less energy is released when water molecules “bond” to the solute than is used to pull the solute apart. Because less energy is released than is used, the molecules of the solution move more slowly, making the temperature decrease.

Explanation:

Is temperature decrease endothermic or exothermic?

Image result for A substance is dissolved in water, and the temperature of the surroundings decrease. Is this process endothermic or exothermic?

There are two methods for distinguishing between exothermic and endothermic reactions. When energy is released in an exothermic reaction, the temperature of the reaction mixture increases. When energy is absorbed in an endothermic reaction, the temperature decreases.

ipn [44]

Since the Pitx1 gene codes for a protein crucial im lower limns development, a mutation occurring near Pitx1 gene will affect refikjs around the lower limbs but not those far away from it.

<h3>What are mutations?</h3>

Mutations refers to alterations or error that occur which change the original sequence of nucleotides in a DNA molecule.

The Pitx1 gene is a gene that codes for a protein that involved in development of the lower limbs.

A mutation near but outside of the coding region of Pitx1 may cause a loss of pelvic fins without pleiotropic effects on the pituitary gland and jaw because the pelvic fins form part of the lower limbs whole the jaws and the pituitary gland are not found in the lower limbs.

Therefore, the mutation occurring near Pitx1 gene will affect regions around the lower limbs but not those far away from it.
