You are a researcher interested in a rare, highly endangered bird species that lives in a very remote area of the Amazonian rain

forest. Almost nothing is currently known about this species’ diet, behavior, life-span, breeding system, or its interactions with other species. Use your knowledge of the definition of ecology, the scales at which ecological research is conducted, and experimental design.
1. Which ecological level (or levels) would you focus on in your research? Justify why you would choose this level (or levels), and explain why you would not choose the others.
2. Would you use an observational, experimental, or modeling approach to study this rare bird species? Why would the approach you chose be a better choice than the others for your study?

Answer:

- Ecological levels to consider in this study: organism, population and community

- Approach: I would use an observational approach to study this bird species

Explanation:

The levels of the ecological organization include the organism, population, community, ecosystem, and biosphere (from simplest to most complex). In this exploratory study, it is imperative to consider: 1-morphological, physiological and behavioral adaptations of the bird species (i.e., organismal-level), 2- size/density/structure of the bird population (i.e., population-level), and 3-interactions between bird population and other populations (i.e., community-level). The higher ecological levels, i.e., ecosystem-level (relationships between the community and abiotic factors ) and biosphere-level (biosphere =  planet Earth), can be in this case disregarded because this study is centered on a focus bird species. Moreover, it is expected to apply an observational strategy because nothing is currently known about the focus bird species. The experimental and modeling approaches seem more suitable to test a particular hypothesis being discussed (it is not the case for this study).

Some microbial control agents are able to _____ cell proteins by breaking bonds that maintain the native state, three-dimensiona
Igoryamba

Answer: option A - denature

Explanation:

Microbial control agents are KNOWN to DENATURE cell proteins as a step in pathology of many diseases.

And because PROTEINS ACTIVITY depends on their three dimensional configuration, microbe attack and BREAK the bond in order to penetrate the cell membrane.

So, the ONLY right option is A

Simone is training for a swim race. How can she make sure she always trains at the same speed of 2 miles per hour? Check all tha
Kipish [7]

Answer:

B. Every point on the line is an equivalent ratio.

C. As the line goes up, the speed increases.

D. Simone can pick any ratio on the line and she will be swimming at a rate of 2 mph.

Explanation:

If the line on the graph has equivalent ratio, it shows that the Simone swim at the speed of 2 mph. If the line on the graph goes up , it means the speed of swimming increases while when the line on the graph goes down, the swimming speed decreases so maintaining the speed of 2 mph, the line have to go horizontally in straight line. If Simone can pick any ratio on the line present on the graph so she has to swimming at a rate of 2 mph.

In our bodies, enzymes in our saliva and pancreas hydrolyse polysaccarides like starch and dissacharides (sucrose) to produce gl
Stolb23 [73]

Explanation:

The enzymatic digestion of starch by amylase can be performed in the laboratory by several ways. But below there is an example of it

In order to have the best protein performance we have to set the temperature of the reaction to 37 celsius degrees.

  • Prepare a starch solution and spread into tubes
  • Prepare an amylase solution and spread into tubes
  • Adjust the pH to the optimum range with buffers, that is about 6.7 to 7.
  • Adjust the temperature of the tubes reaction to 37 celsius degrees.

The wrong temperature and the pH can unfold the enzymes and make the binding site inefficient.

  • Pipette the starch solution in the tubes with enzymes.

By the final step the glucose will be produced by the enzymatic digestion of amylase.

It's attached the scheme of the hydrolyzation of a starch strain

marshall27 [118]

Answer:

The options

a. sympatric speciation; vicariance

b. allopatric speciation; vicariance

c. sympatric speciation; dispersal

d. allopatric speciation; dispersal

The CORRECT ANSWER IS d.

d. allopatric speciation; dispersal

Explanation:

Allopatric speciation takes place either via dispersal, when some members of a species shifts it's habitat to a separate geographical area which leads to differentiation of the initial group into separate diverse varieties or species(as in our case study).

Allopatric speciation through dispersal could results in multiple speciation leading to an individual original species producing diverse new species; this occurrence is called adaptive radiation.

In some scenario, a population of an individual species disperses all over a region with each locating a separate niche or isolated habitat. In the course of time, the diverse demands of their just formed lifestyles causes multiple speciation events that comes from a singular species.
