12.What did Chargaff said about DNA molecules?
Drupady [299]

Answer:

Chargaff rule: The rule that in DNA there is always equality in quantity between the bases A and T and between the bases G and C. (A is adenine, T is thymine, G is guanine, and C is cytosine.) Named for the great Austrian-American biochemist Erwin Chargaff (1905-2002) at Columbia University who discovered this rule.

In air, the 57 GHz radio wave has a shorter<br> wavelength compared to the 64 GHz radio wave.
dalvyx [7]

Answer:

False

Explanation:

Higher frequency signals have shorter wavelengths. Hence, the 64 GHz signal will have a shorter wavelength than the 57 GHz signal.

Frequency and wavelength are inversely proportional meaning as frequency increases wavelength decreases and as frequency decreases wavelength increases.

Cheers.

Two vectors A and B are added to give a resultant R. The components of A are Ax = -8.0 units and Ay = 6.0 units and the componen
Georgia [21]

Answer:

<em>10.09 units</em>

Explanation:

For the A

Ax = -8.0 units

Ay = 6.0 units

The resultant vector = Ra = \sqrt{A^2_{x} + A^2_{y}  }

Ra = \sqrt{(-8)^2 + 6^2  } =  10 units

For B

Bx = 1.0 units

By = -1.0 units

The resultant vector = Rb = \sqrt{B^2_{x} + B^2_{y}  }

Rb = \sqrt{1^2 + (-1)^2  } = \sqrt{2} units

Adding these two vectors A and B together, magnitude of vector R is

R = \sqrt{R^2_{a} + R^2_{b}  }

R =  \sqrt{10^2 + (\sqrt{2} ) ^2} = <em>10.09 units</em>
