Answer:
B. In the real world, random and unpredictable events occur, so the Lotka-Volterra parameters vary over time
Explanation:
Lotka-Volterra equations are mathematical models that explain biological prey-predator interactions among two species, considering the following 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.
- In the absence of the prey, the predator population decreases exponentially. The predator environment is also ideal, but it is limited by the prey density.
- The predation rate is proportional to the encounters rate, which also depends on density.
- The predators affect the prey populations, making it decrease proportionally to the number of prey and predators present.
- The prey population also influence 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 preys.
The parameters are always constant:
- a1: predator hunting success.
- r2: predator growth rate.
- a2: the success of the predator in hunting and feeding.
In nature, there are many factors affecting interactions. Dense-dependent factors and dense-independent factors. Also in reality there are stochastic factors. <em>Stochasticity refers to the variability in the system involving those factors that are affecting or influencing the population growth. Stochasticity might be related to good years and bad years for population growth.</em>
In a real situation, the compliance of the whole assumptions does not occur. The previously mentioned constants might vary, changing continuously the interaction among the predator and the prey. These parameters change in different degrees, resulting in different circumstances for both species.
<span>I could only imagine that the nurse would be a bit taken aback that the paitent is using mineral oil and shoving it up their own buttocks. The nurse would report this to the doctor on call or the RN of which she can discuss proper remedy for the client. Proper responses from the nurse would also include the how to's in doing this correctly if this indeed is what the paitent is wanting to continue as far as short term relief over finding out what is causing the problem in the first place.</span>
Answer:
The correct answer will be option-C.
Explanation:
A karyotype is the visual representation of the chromosome numbers present in a cell of an organism.
The karyotyping is a technique performed to prepare the karyotype of the organism which plays an important role in analyzing the chromosomal abnormalities of the organism.
The analysis of the chromosomal abnormalities helps us study the genetic disorder and diagnose genetic disease. The karyotyping is performed during pregnancy which helps visualize the disease in a family with a history of genetic disorders.
Thus, Option-C is the correct answer.
<span>The nurse should assure the client that the
condition of her baby is normal. The fundus should be at xiphoid process of the
sternum by 36 weeks and measurement of fundal height is use as tool for gauging
fetal growth. Moreover, the nurse should remind the mother to take care of
herself and should consult a doctor if she may experience sudden sharp
abdominal pain or vaginal bleeding.</span>
Answer:
C. Genetic material composed of nucleic acid
Explanation:
The information needed by every organism to perform life functions like reproduction, growth etc are held in the genetic material that the organism carries in its genome. Every genetic material of organisms is composed of nucleic acids, which are only two in nature i.e. Ribonucleic acid (RNA) and Deoxyribonucleic acid (DNA). This is a common feature of all organisms including bacteria and viruses that they contain genetic material which must be in form of a nucleic acid.
The viruses do not undergo a cell division, neither do they contain protein synthesis structures called Ribosomes because they do not have the ability to reproduce or perform any living process outside a living host cell. This means that they strictly depend on another organism's transcriptional, translational, replicational ability to survive.
