4. Answer

Pelvic floor muscles
Stomach muscles
Abdominal muscles
Perineal muscles
Uterine muscles

Explanation

Abdominal muscles are stretched to their limit by term. They greatly decrease the ability to perform strong contraction.
Pelvic floor is vulnerable to muscular and neurological injury during labor and delivery.
Perineal muscle tightening strengthens the pubococcygeus muscle and increases its tone.

Where do most of the nerve fibers of the sympathetic division of the autonomic motor pathways arise from?

Gnom [1K]

Most of the nerve fibers of the sympathetic division of the autonomic motor pathways arise from the inter-mediolateral horns of the gray matter of spinal cord.

<h3>What is sympathetic nervous system ?</h3>

The autonomic system is up two types such as the sympathetic and parasympathetic systems.

Both subsystem work antagonistically but in an integrated manner.

Sympathetic system is highly essential for preparing our body during emergencies for 3 F responses such as fight, fright and flight.

During this response, sympathetic system activates complex pathways for faster breathing, increased heart rate and blood pressure.

Hence, the inter-mediolateral horns of the gray matter of spinal cord is correct answer.

In an ecosystem, the herring population was reduced by fishermen. As a result, the tuna, which feed on the herring, disappeared.

Mkey [24]

Answer:

-------> Herring---------> Tuna

/

Sand eels ⇒/

\

---------> Cod -----------> Seabirds

Explanation:

Food Web is the complex interplay of interconnection between food chains and a graphical representation of what-eats-what in an ecological community.

From the question, the herring population was reduced by fishermen and as a result the tuna which feed on the herring disappeared. This implies that the tuna depends solely on the herrings for feeding. without they wont survive.

As we proceed, we were being told that the sand eels which are eaten by herring, increased in number.

If we pay close attention, we will understand that due to the reduction of the herrings made the sand eels to increased in numbers. The point is that herrings also feed on the sand eels, but as the herrings is being reduced by some anthropogenic factors caused by the fishermen the sand eels increased.

Also, the fishermen overharvested the sand eel population and the aftermath effect shows reduction in Cod and Seabirds. This implies that Cod feeds on sand eels and Seabirds feeds on Cod, but as the food chain is being disrupted by overharvesting of the sand eels, the effect was shown by a decreased in the Cod and Seabirds.

Therefore, the best diagrammatic representation that could fit best for this explanation is:

-------> Herring---------> Tuna

/

Sand eels ⇒/

\

---------> Cod -----------> Seabirds
