The question, which is what the researcher wants to know, could be the following: <em>What is the effect of the change in </em><em>available</em><em> </em><em>food</em><em> </em><em>sources</em><em> on the</em><em> birds' feeding habits</em><em>?</em>

<h3>What are the steps of the scientific method?</h3>

There are different steps to follow in a scientific method

  • Definition and problem statement. The question for which there is no answer yet. A question the investigator wants to answer.

  • Goal specification. The goal is what the investigator wants to know.

  • Hypothesis formulation. The researcher hypothesizes in order to predict what is going on or what is expected to occur.

  • Experiment. Different variables influencing the project are considered. Data collection and analysis stages. This step involves testing the observations.

  • Results

  • Discussion and hypothesis verification. This step involves the deriving of the working hypothesis.

  • Conclusions.

In the exposed example, the experiment involves watching the birds feed, and then removing fruit to simulate an environmental change.

The independent variable here is the food source availability.

The dependent variable is the birds' response to the change.

The question, which is what the researcher wants to know, could be as follows,

What is the effect of the change in available food sources on the birds' feeding habits?

Earths four major spheres are the?
aleksklad [387]

Everything in Earth's system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called “spheres.” Specifically, they are the lithosphere (land), hydrosphere (water), biosphere (living things), and atmosphere (air)...

I hope this helps you with biology...

If a meal supplies 110 g of carbohydrates, 25 g of protein, 20 g of fat, and the equivalent of 5 g of alcohol, what % of the kca
mars1129 [50]

Answer:

0.058 % kcalories comes from carbohydrate.

Explanation:

1 g of carbohydrtes gives 4 calories, 1 g of protein gives 4 kcalories, 1 gm of fat gives 9 calories and 1 g of alcohol gives 7 calories of energy.

Thus in a meal  that contains 110 g carbohydrates gives 110 x 4 = 440 calories,  25 g protein gives 25 x 4 = 100 calories, 20 g fat gives 20 x 9 = 180 calories and 5 g alcohol gives 5 x 7 =  35 calories.

Total calories in a meal  440+100+180+35 = 755.

Therefore % of carbogydrate will be 440x 100 divided by 755 = 58.27 %

In kcalories % would be 58.27/1000 = 0.5827 %

To detect immunoglobulin m (igm)antibodies in an acute phase,blood should be collected in _____ days after the onset of infectio
Gnom [1K]

To detect immunoglobulin m (IgM)antibodies in an acute phase, blood should be collected 7 days after the onset of infection.

  • IgM and IgG antibodies to SARS-CoV-2 may both be found shortly after infection. IgG is typically detectable for extended periods of time, but IgM is most effective for diagnosing recent infection and typically becomes undetectable weeks to months after infection.
  • IgM antibody detection is frequently viewed as a sign of an acute infection. Due to cross-reactivity with IgM antibodies to other, closely related bacteria or other interfering chemicals, false-positive IgM findings are, nonetheless, frequently observed.
  • A positive IgM result may not always indicate an "acute" infection, and additional testing (such as IgG testing) may be required to interpret results because IgM antibodies may be detectable for 2-4 months (or longer) after disease resolution.
  • For many infections, the onset of a measurable antibody response is 5-7 days after the infection. If samples are taken before infection, the initial IgM test results may be negative. Antibody production Immunosuppressed patients may also continue to be seronegative.

Leigh has collected data and performed statistical
lana [24]

Answer:

She will obtain results to support -or reject- her working hypothesis. These results are subjected to statistical analyses in order to confirm that they are statistically significant

Explanation:

The scientific method is a rigorous process that consists of raising a working hypothesis, which is tested by experimentation or observational procedures and analysis of the results. The statistical analyses may have key roles during this procedure. In an experiment that involves statistical analyses, the results are subjected to statistical measures to evaluate the significance level and thus confirm (or reject) the statements made in the working hypothesis. The p-value is one of the most used statistical measures to determine if differences are due to randomness, or they are statistically significant.
