Who were the contributing scientists that discovered how muscle contraction worked​

Biology
1 answer:
Contact [7]4 years ago
5 0

Andrew Huxley and Niedergerke are the scientists that discovered the sliding filament theory.  

<h3><u>Explanation:</u></h3>

They said that the muscle filaments are made up of proteins like actin and myosin. Actin is the thinner protein that is formed of two subunits – G actin and the F actin. They together form the actin filament.

Myosin filament is formed of the units Heavy meromyosin and light meromyosin. These together make the myosin filament. These filaments slide over each other and attach themselves to make the muscle contract.

2.Terms in this set

  • acetylcholine. A neurotransmitter used by neurons in the PNS and CNS in the control of functions ranging from muscle contraction and heart rate to digestion and memory.
  • norepinephrine.
  • serotonin.
  • dopamine.
  • GABA.
  • glutamate.
  • endorphin.

3.Neurotransmitters are made of the following :

  • The amino acid neurotransmitters glutamate, GABA (γ-aminobutyric acid), and glycine. All of these are amino acids, though GABA is not an amino acid that's found in proteins. ...
  • The biogenic amines dopamine, norepinephrine, epinephrine, serotonin, and histamine, which are made from amino acid precursors.

4.Neurotransmitters can impact a specific area of the brain, including behavior or mood, their malfunctions can cause effects ranging from mood swings to aggression and anxiety. ... Understanding the way neurotransmitters function in the brain could lead to better treatments for mental disorders.

What is the main type of weathering in deserts?
Whitepunk [10]

<u>Answer:</u>

The major type of weathering that takes place in a desert in Physical Weathering.

<u>Explanation:  </u>

Physical weathering also known as mechanical weathering takes place in deserts. This weathering takes place due to physical or mechanical forces. Frost chattering, temperature fluctuation also causes physical weathering.

In the desert, there is a fluctuation in temperature. In deserts, the temperature during the day will be very high and at night the temperature will be very low. As a result, the rocks expand during daytime due to heating and at night the rocks undergo contraction due to the reduction in temperature. Hence the rocks are weakened followed by the disintegration or breaking of rock.

Why the bass and crayfish benefit from an increased level of phosphate, initially, but then die off
omeli [17]

Answer:

Increased levels of phosphate are beneficial to phytoplankton and aquatic plants. In the short-run, this means increased micronutrients for herbivorous and omnivorous fish.

The phosphate, however, reacts with the water to reduce the oxygen levels obtainable in the water. Without oxygen, the fishes die off.

It is not unusual to find that with increased phosphate in water, healthy fishes begin to die off without any other plausible explanation.

The solution is to clean the water or treat it with solutions that impact positively whilst reducing the phosphate levels.

Cheers!
