As you saw in Part C, the body sizes of sympatric and allopatric P. cinereus and P. hoffmani are consistent with a hypothesis of character displacement resulting from interspecific competition. What additional information would strengthen the argument that character displacement is in fact responsible for body size evolution in these salamanders

Answers

Answer 1

Answer:

Divergence in the body size trait between both species occurred once they were living together. The evolution of the trait difference occurred after sympatry.

Explanation:

Close species, P. cinereus and P. hoffmani, mostly live in different regions. In allopatry, both species have the same -or very similar- body size. Body size in these species is a heritable trait.

However, there are some areas where P. cinereus and P. hoffmani coexist. When they are in sympatry, P. cinereus exhibits a smaller body size and feeds on smaller prey items than allopatric P. cinereus. On the other hand, sympatric P. hoffmani exhibit bigger bodies, feeding on bigger prey items than the allopatric P. hoffmani.

So, when both species are in sympatry, they develop different morphological traits to avoid competition between them and manage to coexist in the same area. Resource availability is limited, so P. cinereus became smaller and feeds on small prey, while P. hoffmani became bigger and feeds on bigger prey. Through this trait divergence, they got to live longer and reproduce more, decreasing interspecific competition and increasing their fitness.

Allopatric species feed on similar prey items and have similar body sizes, reflecting that the divergence occurred after sympatry. If species living in allopatry were places together in the same habitat, they would exhibit strong competition that, over time, would drive to character displacement.

do you think that the life of elderly people suffering from diabetes mellitus should be extended by giving them artificially produced insulin​

Answers

Explanation:

The prevalence of type 2 diabetes is increasing among older adults as is their diabetes-related mortality rate. Studies suggest that tighter glucose control reduces complications in elderly patients. However, too low a glycosylated hemoglobin (HbA1c) value is associated with increased hypoglycemia. Moreover, the appropriateness of most clinical trial data and standards of care related to diabetes management in elderly patients is questionable given their heterogeneity. Having guidelines to safely achieve glycemic control in elderly patients is crucial. One of the biggest challenges in achieving tighter control is predicting when peak insulin action will occur. The clinician’s options have increased with new insulin analogs that physiologically match the insulin peaks of the normal glycemic state, enabling patients to achieve the tighter diabetes control in a potentially safer way. We discuss the function of insulin in managing diabetes and how the new insulin analogs modify that state. We offer some practical considerations for individualizing treatment for elderly patients with diabetes, including how to incorporate these agents into current regimens using several methods to help match carbohydrate intake with insulin requirements. Summarizing guidelines that focus on elderly patients hopefully will help reduce crises and complications in this growing segment of the population.

In humans, ventilation, digestion, and blood flow are important biological processes. Explain the relationship between the structure of tissues or organs and one of these processes.

Answers

Answer:

I am assuming the question is asking how do the processes relate to one another.

Explanation:

Ventilation happens in the lungs, where carbon dioxide and oxygen are exchanged in the alveoli. This is done via cappilaries that surround the alveoli. Cappilaries are small blood vessels, which are collecitelvy part of the blood flow system (circulation) of the body. In reguards to the digestion, there are capillaries in the vili (which are tiny finger-like structures) so that they can pick up the nutrients during digestion. Another way blood flow and digestion are connected is because the stomach is a muscle, thus is moves and requires energy. That energy comes from the oxygen and nutrients that is supplied by the blood. These are just some examples.

Answers

Answer:

Natural selection.

Explanation:

Natural selection can be defined as a biological process in which species of living organisms having certain traits that enable them to adapt to environmental factors such as predators, competition for food, climate change, sex mates, etc., tend to survive and reproduce, as well as passing on their genes to subsequent generations.

Simply stated, natural selection entails the survival of the fittest. Therefore, the species that are able to adapt to the environment will increase in number while the ones who can't adapt will die and go into extinction.

In this scenario, the mechanism of evolution responsible for this was natural selection because after about 40 generations the evolution of reproductive isolation was under way for the fruit fly. Thus, the more the offsprings that are reproduced by the parent organism, the more likely are they to survive.

Additionally, there is a better chance of having good or beneficial traits being passed from the parent organism to her offsprings.

how does the energy of the reactants and products differ between an energy absorbing reaction and an energy releasing reaction

Answers

In an energy absorbing reaction, the energy of the products is greater than the energy of the reactants. In an energy releasing reaction, the energy of the reactants is greater than the energy of the products.

The mass of the products is larger than the concentration of the reactants in an energy absorption process.

The power of the reaction mixture is larger than the radiation of the outputs in an energy-releasing process.

As substances disrupt bonds, energy released, and then when outputs make new bonds, release energy

Exothermic processes release energy, whereas endothermic reactions consume it. There is no general change in the quantity of energy throughout a chemical process, whether it collects or releases it.

Where is amyglada located in a brain ? How does it function ?​

Answers

Short Answer: The amygdala is located in the brain and its functions are related to emotional learning.

Explanation

The amygdala is a brain structure located in the temporal lobe of the brain. Its functions are related to the emotional system of the brain, and memory. In addition, the amygdala has been shown to influence the emotional learning process. The amygdala is mainly responsible for the formation and storage of memories associated with emotional events, so external sensory stimuli reach the basolateral group of the amygdala, where associations are formed with memories of the stimulus (mainly related to fear).

Earth to change?

Answers

The change in the tilt of the Earth can affect the distribution of sunlight and thus influence temperatures on Earth.

Earth's tilt and temperature

The tilt of the Earth, known as obliquity, affects the distribution of sunlight and influences temperatures.

A greater tilt leads to more pronounced seasons, with hotter summers and colder winters, while a lesser tilt reduces the seasonal contrast. These changes occur over long timescales.

However, short-term climate variations are primarily influenced by factors like greenhouse gases, ocean currents, and atmospheric circulation patterns.

Organisms in the rainforest compete for biotic and abiotic factor by using resources that are available in the surrounding environment.

Competition occurs when the resources are available in scarce or limited amount. When there is an abundant amount of resources, there is no competition between organisms. The organism which is stronger than other organism can use more resources i.e. water, food and space etc and increase its population.

Those organisms which feed on similar food and other resources can compete with each other and the stronger organism will use the resources in large amount.
