1 answer:

7 0

Muscles work by getting electrical impulses from the brain and the impulses signal them to contract by releasing calcium in sarcoplasmic reticulum of the muscle cells. When there’s fatigue, muscles are unable to generate force and it may caused by: nerve or muscle fibers limitations, which may be a result of tremendous workout or exercise. Nerves during neural fatigue are unable to generate signals to the muscles, while reduced activity in muscle fibers disable muscles to contract causing metabolic fatigue.

What is the biggest contributor to the Louisiana Wetlands/Delta Region?

Kryger [21]

Answer:

Wetlands House Oil and Gas Infrastructure along with many other natural factors are one of the leading contributors.

Explanation:

On the Gulf of Mexico, an area of about 300 kilometers is called Louisiana Wetlands. These are barrier islands.

The area of this place constantly suffers from digging of holes and pipelines which are being established underground. This promotes soil erosion.

The nutritive soil layer washes away with dirt or grime left behind.

Many plants get killed because of this phenomenon.

This region is already made up of marshes and swaps which are further elevated by natural forces like hurricanes, storms, floods etc.

The water from Mississippi River has formed an inlet and outlet in this area resulting in a mixture of brackish water.

Should the government place a special tax on fast food? eng4uv

kompoz [17]

This is an opinion question, so here is what I would answer with:

The government should not place special taxes on fast food as it is how some people survive. People with low income cannot simply run to the grocery store and get everything to make a burger and fries. They must rely on large fast food chains to give them healthy, enough, food for survival.

OR...

The government should place special taxes on fast food. This would increase the prices on foods sold. This said pricing could detour the public to making healthier, cheaper food choices.
