How many neuromuscular junctions are in each muscle cell

Biology
1 answer:
yuradex [85]3 years ago
5 0

Answer: One

Explanation:

A neuromuscular junction is a chemical synapse between the muscle fibre and the motor neuron. It helps the motor neuron to send a signal to the muscle fibre, triggering contraction in the muscle.

One Muscle Fiber has one neuromuscular junction in most skeletal muscles. A mature neuromuscular junction is innervated by one motor nerve terminal ; thus, the relationship between a given muscle fibre and motor neuron is one-to-one.

Humans store excess polysaccharides in the form of
Nuetrik [128]

Humans store excess polysaccharides in the form of glycogen.

Polysaccharides are carbohydrates. They are generally used to generate energy in the form of ATP for the body's metabolic activities.

Carbohydrates are broken down during respiration to generate energy. Excess carbohydrates are generally converted to glycogen through the actions of an enzyme in the liver.

Glycogens are converted back to simpler carbohydrates when there is inadequate carbohydrate in the body.

Which answer best defines what the Lotka-Volterra predator-prey model mathematically describes?-The competition among many preda
yanalaym [24]

Answer:

The simultaneous effect of a predator population on a prey population and a prey population on a predator population over time.

Explanation:  

The mathematical models of Lotka-Volterra equations explain the existing interaction between species in which prey and predator influence and affect each other. The model follows a few assumptions,    

  • The ecosystem is isolated and closed. There is no migration.
  • The whole individuals are reproductively equivalent.
  • In the absence of the predator, prey shows an exponential growth rate. The prey is in the ideal environment.  
  • When there is no prey, the predator population decreases exponentially because of the lack of food. The predator environment is ideal, but it is limited by prey density.  
  • The predation rate is proportional to the encounters rate, which also depends on density.  
  • The predators affect the prey populations, inducing its decrease proportionally to the number of prey and predators present.  
  • The prey population also influences the predator population proportionally to the number of encounters between the two species.  

In these equations, the variable D is the number of predators, and P the number of prey items.

The parameters are always constant:  

• r1: prey growth rate.  

• a1: predator hunting success.  

• r2: predator growth rate.  

• a2: the success of the predator in hunting and feeding.

In nature, many factors affect interactions, such as dense-dependent factors and dense-independent factors. Also, in reality, there are stochastic factors. Stochasticity refers to the variability in the system involving those factors that are affecting or influencing population growth. Stochasticity might be related to good years and bad years for population growth.

In real situations, the compliance of the whole assumption does not occur. The previously mentioned constants might vary, constantly changing the interaction between the predator and the prey. These parameters change in different degrees, resulting in varying circumstances for both species.
