What is an Obligate anaerobe? How do obligate anaerobes, like the bacteria C. Botulinum, get energy ?

Answers

Answer:

See the answer below

Explanation:

Obligate anaerobes are microbes that can only survive in oxygen-deficient environments. They are killed by the normal atmospheric level of oxygen and will only thrive in environments whose oxygen levels are lower than that of normal atmospheric level.

Obligate bacteria such as Clostridium botulinum obtain their energy through anaerobic respiration processes such as fermentation and anaerobic respiration. During this process of fermentation, the lactic acid pathway is mostly used but other fermentation pathways such as propionic acid, mixed acid, acetogenesis, and methanogenesis pathways can be used.

Determine which of the following statements is true about energy in ecosystems A. Consumers pass on 20% of the energy they get from a lower trophic level. OB. Primary consumers lose 60% of the energy they absorb from producers as urine and feces. C. 10% of the energy Primary consumers absorb is lost as heat. Ons Primary producers lose 20% of the energy they absorb as urine and feces.​

Answers

Answer: C. 10% of the energy Primary consumers absorb is lost as heat.

Explanation:

According to the ten percent law of energy flow only 10 percent energy is transferred from one trophic level to the next trophic level and rest of the energy is used to develop the biomass and lost as heat. As the loss of heat is an essential exothermic reaction after the digestion and assimilation of food the energy is lost as heat from the body of the primary consumers is 10%. Primary consumers are animals that are dependent on plants for their food requirements for example deer, goat and others.

Just after they taste a sweet liquid, mice are injected with a drug that produces an immune response. Later, the taste of the sweet liquid by itself triggers an immune response. This best illustrates

Answers

Answer:

This question lacks options, options are:

a) classical conditioning

b) observational learning

c) spontaneous recovery

d) operant conditioning.  

The correct answer is a.

Explanation:

The classical conditioning theory derives from the experiments of the Russian physiologist Ivan Pavlov, he hypothesized that when any stimulus predicts the occurrence of another stimulus that triggers an automatic response, that first stimulus would acquire the ability to trigger that response, in other words , is a type of learning according to which an originally neutral stimulus, which does not provoke a response, becomes able to provoke it thanks to the associative connection of this stimulus with the stimulus that normally provokes said response. The conditioning of the immune response is built on the same principles of the classical conditioning paradigm described by Ivan P. Pavlov in which an environmental stimulus that by itself does not produce any immune reaction (conditioned stimulus), is associated with substances that stimulate or they suppress immune function (unconditioned stimulus), and finally, by presenting the conditioned stimulus alone, trigger the appropriate immune response.

Which answer best defines what the Lotka-Volterra predator-prey model mathematically describes?-The competition among many predator species for a dingle prey species.-The simultaneous effect of a predator population on a prey population and a prey population on a predator population over time.-The effect of a predator population on a prey population.-The capture efficiency and assimilation rate of a predator, which is dependent on the number of individuals in a prey population.

Answers

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.

C. They have a greater surface-to-volume ratio.
O
D. They have a lower surface-to-volume ratio.

Answers

Answer:

C. They have a greater surface-to-volume ratio.

Explanation:

Because these smaller cells can access and pass through the membranes of the other cell membranes and permeable coverings easily and voluntarily unlike larger cells. It is also efficient for these smaller cells to penetrate and travel, delivering and transporting goods and materials such as nutrients, oxygen and waste throughout the body without consuming enough energy and conserving lesser space.

For simple reasons, they are faster, more efficient and consumes little space, and most especially depletes lesser energy. So, many small cells have more surface area than one large cell.

Answers

Answer:

There is no scientific evidence to prove that people with schizophrenia ingest dopamine capable of accumulating excess in the body.

Explanation:

Although you did not specify that your question is associated with the origin of schizophrenia in people, we can see that this is the main topic of your question, due to its context. This is because scientists have been striving to find the origin of this disease, in order to be able to combat it in the early stages. Although many scientists believe that the origin of this disease is associated with excessive intake of dopamine, there is not strong enough scientific evidence to show that this is true. Because of this lack of evidence, filmmakers have focused on associating the origin of the disease with the sensitivity of the dopamine receptor and not with the dopain itself.

Question 2 of 10
Which of the following should be included in a good conclusion?

Answers

Answer:

How to write a conclusion

An effective conclusion is created by following these steps:

Restate the thesis: An effective conclusion brings the reader back to the main point, reminding the reader of the purpose of the essay. However, avoid repeating the thesis verbatim. Paraphrase your argument slightly while still preserving the primary point.

Reiterate your supporting points: Aside from restating your thesis, you should also reiterate the points that you made to support it throughout the paper. But instead of simply repeating the paper's arguments, summarize the ideas.

Make a connection between your opening and closing statements: It's often effective to return to the introduction's themes, giving the reader a strong sense of conclusion. You can accomplish this by using similar concepts, returning to an original scenario or by including the same imagery.

Provide some insight: Your conclusion should leave the reader with a solution, an insight, questions for further study or a call to action. What are the implications of your argument? Why should anyone care? You'll want to answer these types of questions here and leave your audience with something to think about.
