For an individual to detect an odor then molecules must first dissolve in the

mucus before they bind to the receptor sites of the olfactory hairs.

The nose is the organ responsible for smelling and it possesses key

components such as the mucus found in the olfactory epithelium and

receptors found in the olfactory hairs for processing the type of smell to the

brain.

When individuals inhale substances, they are <em>dissolved</em> in the mucus to aid

their binding to the receptors and their subsequent relay of the signal to the

brain for processing.

ancestors of giraffes with shorter necks could not reach branches high up in trees for food. this led to selection for longer-ne
hichkok12 [17]

With shorter necks, giraffe ancestors could not reach food-containing branches on tall trees. This resulted in the directional selection of giraffes with longer necks.

 

<h3>Why is choosing a direction necessary? </h3>

It nearly appears obvious that the giraffe's long neck developed as a result of a lack of food in the lower branches of trees. The giraffe has a significant advantage because it is taller than any other mammal and can feed where few others can. 

When compared to modern giraffes, the giraffe's ancient predecessors had a shorter neck. The plants that were lying at a higher level were inaccessible to them. Giraffe phenotypes have changed in various ways, and now have long necks to reach vegetation that is higher up. The extreme form is chosen above other features in directional selection. It was decided to choose the long-necked giraffe over the short-necked.

Which statement regarding the hypothalamus is FALSE?
Margarita [4]

Answer:

All the options are correct regarding hypothalamus.

Explanation:

The hypothalamus is the part of the forebrain. The diencephalon is divisible into 2 parts - thalamus and hypothalamus. It regulates various functions of the body.

This is the thermoregulatory center of the body. It gives the signal to sweat during a hot environment and shiver in winter. This maintains the water balance in the body by stimulating the secretion of ADH hormone in the kidney.

Hypothalamus also has regulated anterior pituitary hormone secretion. Thus it controls the endocrine secretion of pituitary glands.

This plays an important role in hunger and thirst. The feeding habits like the licking of lips, swallowing, and salivating by seeing delicious foods is due to hypothalamic activities.

The behavioral activities of individuals influenced by the hypothalamus.  It is worked along with the limbic system of the brain. The behavioral activities include fear, punishment and sexual desire.
