"Uncommon" or "emerging" pathogens are ones that are rarely seen in a clinical setting or are new to a geographic area. As a sci

entist, you will need to follow a logical pattern to determine what the unknown virus is. This logical process is one that all scientists are familiar with the scientific method. The scientific method is a process of determining what natural phenomenon is to be studied and developing a series of experiments to determine what is occurring. Order the steps of the scientific method as a virologist would implement them on the job.

Answer:

  • Observe a natural phenomenon or reaction.
  • Devise an explanation of what you have observed.
  • Experiment to support of refute your explanation.
  • Record the results of your experiments.
  • Determine whether your results support or refute your explanation.
  • Determine whether you need to rewrite your explanation or it has withstand testing.

Explanation:

The scientific method of research begins with an observation being made. To understand the observation, questions are made. A hypothesis is generated to answer the question. A hypothesis can be described as a tentative statement that can be proved either right or wrong. To test the hypothesis, experiments are performed. Results are generated and conclusions are drawn. If the hypothesis does not prove to be right, then another hypothesis can be tested.

If a DNA molecule is found to be composed of 40% thymine, what percentage of guanine would be expected.
Likurg_2 [28]

Answer:

10%

Explanation:

Chargaff postulated the complementary base pairing rule, where he stated that in the DNA molecule, Adenine (A) will always pair with Thymine (T) and Guanine (G) with Cytosine (C) i.e. A-T, G-C

Chargaff stated that the concentration of purines (Adenine and Guanine) is always equal to that of pyrimidines (Thymine and Cytosine) i.e. {A} + {G} = {C} + {T}

These equal concentration equals 100% in totality i.e. A+G+C+T= 100%

Thymine pairs with Adenine, if there is 40% of Thymine in the DNA molecule, it means there will be 40% of Adenine also. 40 + 40 = 80%. This leaves us with 100-80 = 20% for Guanine and Cytosine.

Since there will be an equal amount of Guanine and Cytosine too, Guanine will therefore, be 20/2 = 10%.

That is, 10% Guanine, 10% Cytosine.

What are new stars that are found in the spiral arms and formed from recycled dead star material known as?
Arada [10]

Answer:

population I stars.

Explanation:

A star is a giant astronomical or celestial object that is comprised of a luminous sphere of plasma, binded together by its own gravitational force.

It is typically made up of two (2) main hot gas, Hydrogen (H) and Helium (He).

The luminosity of a star can be defined as the total amount of light radiated by the star per second and it is measured in watts (w). Also, the apparent brightness of a star is a measure of the rate at which radiated energy from a star reaches an observer on Earth per square meter per second. The apparent brightness of a star is typically measured in watts per square meter.

Some of the examples of stars are; Canopus, Sun (closest to the Earth), Betelgeus, Antares, Vega etc.

New stars that are found in the spiral arms and formed from recycled dead star material are known as population I stars. Also, it comprises of association and clusters formed a million or billion years ago in the spiral arms of Milky Way galaxy.

A galaxy can be defined as a collection or group of many billions of stars and other planetary body which are existing independently.
