In the ear, the sound waves enter through the auditory canal and hit the eardrum (tympanic membrane). The eardrum amplifies the sound and the waves move on to the middle ear, where three bones called the ossicles (malleus, incus, and stapes) amplify the sound further and vibrate. Then, the sound waves go to the cochlea where tiny hairs and other receptors turn the sound waves into a nerve impulse. This impulse is sent to the brain via the auditory nerve and interpreted by the brain.

Impulses originating in the part of the brain called the medulla would most directly affect which body structure?
gtnhenbr [62]

The question is incomplete. The complete question is:

Question: Impulses originating in the part of the brain called the medulla would most directly affect which body structure?

a. A leg muscle

b. A ligament

c. An arm bone

d. The heart

Answer:

d. The heart

Explanation:

The medulla oblongata contains a number of reflex centers for regulating vital body functions such as heartbeat, breathing, and vasoconstriction. The medulla contains several nuclei, a collection of neuronal cell bodies.

For example, impulses originated in the cardiovascular center regulates the rate and force of the heartbeat and the diameter of blood vessels. Impulses from the cardiovascular center flow along sympathetic and parasympathetic neurons. An increase in sympathetic stimulation from the cardiovascular center of medulla increases heart rate and contractility while a decrease in sympathetic stimulation decreases heart rate and contractility.

This DNA molecule is replicating - write a complimentary strand to this template TAC GGG CAG CAT AAA ATC​
Firdavs [7]

Answer: The complimentary strand will read ATG CCC GTC GTA TTT TAG

Explanation:

The complimentary strand to the replicating DNA molecule is known as messenger RNA (mRNA).

The mRNA directs specific bases to pair the existing base on the replicating DNA strand:

- Adenine (A) pairs only with Thymine (T)

- Guanine (G) pairs only with Cytosine (C)

So, to obtain the complimentary strand of TAC GGG CAG CAT AAA ATC​, substitute each letter with its base pair.

Thus, the complimentary strand will read ATG CCC GTC GTA TTT TAG
