It should be a food web, because there are various producers and consumers, and the bears and humans eat each other
<span>The first-line treatment for the patient should be Omeprazole combined with metronidazole and clarithromycin. The combination of metronidazole, omeprazole and clarithromycin is an effective treatment for pylori infection and and that this regimen remains very effective in the presence of metronidazole-resistant strains.</span>
Answer:
A scientist's response to the increase in food poisoning sick patients should be examining the type and source within the foods consumed.
Explanation:
Food poisoning involves the effects that decomposed or contaminated food can have on a group of people who eat it, and can cause illness in all or most individuals.
Although patients' symptoms should be treated and preventive education provided, the best course of action for a scientist is to investigate the cause.
The response of a scientist to the increase in food poisoning cases is to determine the type and source of food, as well as the nature of the alteration it has -decomposition, contamination, bacteria- in order to <u>eliminate the source and avoid new cases</u>.
- <em>The other options may be valid in the face of the appearance of food poisoning cases, but they are not the best procedure with which a scientist would respond. </em>
Answer:
Conditioned response.
Explanation:
Conditioned response may be defined as a type of learned behavior used in the Pavlov experiment. This type of response mainly generated when the neutral stimulus get mixed with the strong stimulus.
The male quail can be sexually arouse by red light. The red light here acts as the conditioned response because the neutral stimulus (red light) when mixed with the unconditioned stimulus result in the presentation of the female quail and increases the response of the male quail.
Thus, the correct answer is conditioned response.
Answer:
There are several environmental factors that causes changes in the ecosystem and the population of that area such as invasive species, extreme weather, land use change, pollution and disease.
Lets take invasive species as environmental factor. Introduction of invasive species can cause a huge change in the ecosystem and affects the native population in that area. it increases the competition for food resources and decreases the survival rate of their preys.
For example: Water hyacinth (Eichhornia crassipes). It is an invasive plant species that has very bad impact of native population as well as other population, like it reduces biological diversity, oxygen loss, decreased phytoplankton productivity, eliminate plants that animals use for nesting, and alter animal communities by blocking access to the water.
Thus invasive population can affect population by reducing biodiversity, water shortages, decreasing availability and quality of key natural resources, disturb the food chain and can cause natural calamities.
Invasive species affect the resources that native species are using and that decreases the carrying capacity of the native population as it disturbs the whole food chain.
