The mechanisms and processes which lead to new species

Biology
1 answer:
Liula [17]4 years ago
3 0

Answer:

Natural selection and speciation: 'Ecological speciation'.

Natural selection is generally recognized as a central mechanism of evolutionary change within species. ... Thus, the populations cease exchanging genes, thereby diverging into separate species because of the adaptive changes that occurred via natural selection.

Question 5 of 30
djyliett [7]

Which type of society is most likely to have a great number of factories?... Industrial

What is society?

A society is a group of people that regularly contact with one another or a significant social group that inhabits the same physical or social territory and is typically under the control of the same governmental authority and prevailing cultural norms.

A given society may be defined as the sum of all of these relationships among its constituent members. Societies are characterised by patterns of relationships (social relations) between people who share a particular culture and institutions. In the social sciences, subgroup domination or stratification patterns frequently appear in bigger societies.

By designating particular behaviours or ideas as acceptable or unacceptable, societies create patterns of behaviour. The term "societal norms" refers to certain behavioural patterns within a particular community. Societies and their standards are constantly and gradually changing.

Hence the correct answer is OC. Industrial

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.

The papillae located mainly on the tip and sides of the tongue that contain only a few taste buds each are the _______ papillae
liraira [26]

Answer:

Fungiform

Explanation:

The papillae located mainly on the tip and sides of the tongue that contain only a few taste buds each are the Fungiform papillae.

The fungiform papillae are broad flat structures that house taste buds in the central portion of the dorsum (back) of the tongue. These papillae were thought to resemble a fungus: a little mushroom. The literal meaning of Fungiform is mushroom-shaped.
