Answer:

  • <u>Medullary hormones</u>: the epineprhin and the norepineprhin. <u>Five different effects that these hormones produce are:</u> increase heart rate, produce cardiac muscle contraction, elevate blood preasure, increase breathing, dicrease digestive activity, increase metabolic rate.
  • <u>The most important mineralocorticoid secreted by the adrenal cortex: </u>aldosterone.
  • <u>Actions of the aldosterone: 1. </u>Conserves sodioum ions and water in kidneys. 2. Excrete potasium ions 3. Conserves H2O.

Explanation:

The epineprhin and norepineprhin are the most important medullary hormons. They are so important because of the functions that they have. They are responsable for the increase of heart rate and if it´s movement, along with digestive and metabolic activity.

Thanks to the aldosterone which is the most important secreted minaralocoricoid, kidneys conserve water and sodium and eliminate posatium.

Which picture should I use for supporting that my hypothesis was not supported? And please make a good explanation of the pictur
yanalaym [24]

Answer:

You should probably use the third picture to support that your hypothesis was incorrect.

Explanation:

I do not know what your project was, but it seems as though you were able to gather that the state of matter is liquid throughout the experiemnt using the last picture. If your hypothesis was that the state of matter would change, then the third picture would show that this is wrong, as it remains in a liquid state.

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.
