  • From different wavelengths we can create a electromagnetic spectrum .
  • From spectral lines of that electromagnetic spectrum astronomers can determine the element in the farther universe (star).
  • They can also determine the temperature and density of that element in the star.
  • The spectral lines in the electromagnetic spectrum tell us about any magnetic field of the star.

A useful formula of wavelength:

\\ \sf\longmapsto \lambda=\dfrac{c}{v}

  • wavelength is the length 7 of wave having SI unit lambda

hershey and chase confirmed that dna, not protein, was the genetic material. how do the results of their two experiments support
Gwar [14]

Hi,

Harshey and Chase did a great experimentation which was basically a two step experiment to prove that DNA and not proteins are the actual carriers of genetic information from parents to offspring.

  • In the first part of their experiment, they used bacteriophages (virus that eat bacteria). They used radioactively labeled sulphur(35S) medium to grow bacteriophages and observed that all the bacteriophages had proteins with radioactive sulphur(35S).
  • In the next step they allowed these phages to infect bacteria and to their surprise, they found that the bacteria did not had radioactively labeled sulphur in them because the coat of bacteriophage stays outside the body of bacteria when it attacks it. This proved that DNA not proteins were the hereditary material.
  • To make their results more reliable, they did a second experimentation in which, they marked the DNA of the phage with radioactive phosphorus 32P. After labeling DNA, they repeated the same experiment and this time, they found radioactive phosphorus inside the bacteria.

<em>This meant that the bacteria had DNA of phage entered inside them and this again proved that DNA not proteins are the hereditary material. You can see attached image for better understanding. </em>

Hope it help!

The "lub" heart sound is due to the Select one: a. onward rush of blood to the heart. b. contraction of aortic muscle tissue. c.
adelina 88 [10]

Answer: Option D.

The lub heart sound is due to the closing of atrioventricular valves.

Explanation:

Heart sounds are noises that are generated from beatings from heart and from blood that flows through it. The heart sound reflect the turbulence generated when the heart valves snap shut. Lub is the first heart sound also called S1 and it is caused by turbulence and closure of the atrioventricular valves(mitral and triscupid valves) at the start of systole. The second sound is the dub sound which caused by the closing of aortic and pulmonic valves at the end of systole.
