The medulla has the ascending and the descending tract which function to link the brain with the spinal cord.

<h3>What is the role of medulla?</h3>

Medulla oblongata is the lowermost part of the brain.
It is located at the place where the brain and the spinal cord connect thus it carries nerve signals between the brain to spinal cord thus help the entire body to communicate.
It controls biological processes like blood pressure, breathing and heartbeat.
Ascending tract functions to carry sensory information from the body (e.g.: pain) from the spinal cord to the brain (upwards).
Descending tract carry motor information (e.g.: instructions to move the arm) from the brain down the spinal cord to the body (downward).
Damage to medulla can lead to respiratory failure, paralysis, or loss of sensation.

Explanation:

(SIADH) or known as syndrome of inappropriate secretion of antidiuretic hormone is a disorder of impaired water excretion caused by the inability to suppress the secretion of antidiuretic hormone.

The characteristics that best describe SIADH is: Fluid retention, serum hypoosmolality, dilutional hyponatremia, and concentrated urine with normal intravascular volume .

Answer:

auditory cortex

Explanation:

Sensory information passes both the auditory and the limbic systems by the means of medial geniculate nucleus (MGN), a small oval mass that protrudes slightly from the underside of the thalamus, a big double-lobed structure buried under the cerebral cortex. Before the signal can travel on, however, it passes through another nearby structure called the thalamic reticular nucleus (TRN), which evaluates whether or not it should be passed on.

Adapt extinct mutation

lisabon 2012 [21]

That organism will survive in the future which adapt themselves according to the environment.

<h3>What is fitness?</h3>

Fittest is the term describes living things that are best suited to their environment.

Species that survive are the ones that adapt, make or meet changes.

Florida has a rich fossil record spanning from the Eocene to recent times. Florida fossils are often very well preserved.

Two examples of land animal fossils found in Florida are the giant sloth and the saber-tooth tiger.

Some animals unable to adapt to the changing environment became extinct .

Living things mutate over time to meet their changing environment.

This biologist, Darwin, studied evolution in the 1800s.

The glyptodont was a giant, armadillo-like animal with a spiked tail that once lived in Florida.

The Origin of Species is a book written in 1859 about natural selection.

Nature selects the fittest for survival because they have useful traits.

Changes may occur in animals due to changes in the sequence of base pairs in their DNA, and this is known as a mutation.

Oldfield mice show variation in the color of their fur.

The survival of the light-colored old field mice on Florida's Gulf Coast is an example of the process called adaptation.

Evolution is a controversial theory that has survived much criticism.
