Answer:

CODIS stands for Combined DNA Index Systems and is a computer program that stores the DNA Fingerprint of convicted criminals and missing persons. This program is very useful in forensic science.

Explanation:

CODIS is a computer program maintained by the FBI, which operates databases across the country. These databases contain more than five million profiles. CODIS covers several different indices.

CODIS uses algorithms to compare 13 different locations in STRs, plus one that determines the gender of the person in question. The system has rules and safeguards to protect the privacy of people in the database. Algorithms that point to positive results - which must be confirmed by an analyst - can provide clues to the police or even identify a possible criminal. The downside of using CODIS is that it only covers the profiles it includes - and there are over a million profiles waiting to be included in the system.

The Combined DNA Index System (CODIS) is the United States national DNA database created and maintained by the Federal Bureau of Investigation. CODIS consists of three levels of information; Local DNA Index Systems (LDIS) where DNA profiles originate, State DNA Index Systems (SDIS) which allows for laboratories within states to share information, and the National DNA Index System (NDIS) which allows states to compare DNA information with one another.

Air pollution is caused the burning of fossil fuels, resulting in the formation of smog and acid rain.

<h3>What is air pollution?</h3>

Air pollution is the release of harmful substances into the air which makes it unfit and unhealthy for breathing.

Substance which pollute the air are known as air pollutants.

The burning of fossil fuels causes dangerous gases to enter the atmosphere. Heavy, dense fog caused by dangerous gases mixing in the atmosphere is called smog. Acid rain occurs when dangerous gases mix in the atmosphere and fall back to the surface in liquid form.

Therefore, air pollution is caused by releasing pollutants air.

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.
