Taste receptors on the tongue are not related to smell receptors of the nose.

tekilochka [14]

Answer:

<u>b. False</u>

Explanation:

As human has about 350 olfactory receptors and subtypes work in various conditions allowing us to sense about 10,000 doors. All senses of smell and tastes merge at the back of the throat.

As you taste something before smelling it the smell lingers on inside in the nose which makes you smell it. As both the smell and taste are chemoreceptors which means both have chemically same sensing environments.

In addition, the division of taste receptors within the nose coordinate with activities, although humans can distinguish between the tastes from the smells of the objects.

Working together to create a perception of flavor through the nasal passage.

Determine the proportion of offspring phenotypes that would result when two merle dogs mate, if both dogs are heterozygous (Ll)

Brut [27]

Answer:

75% would have the dominant traits for coat length, 25% would have recessive trait for coat length.

Explanation:

After completing a punnet square, we could find that our genotypes are 25% LL, 50% Ll, and 25% ll.

If these genotypes were to be physically expressed, LL and Ll would both be expressed as showing the dominant trait.

This means that 75% would have the dominant traits for coat length and 25% would have recessive trait for coat length.
