The correct answer of this question is : A) Radio waves have longer wavelengths, lower frequency, and lower energy than ultraviolet waves and x-rays.
EXPLANATION :
Before going to answer this question, first we have to know the electromagnetic spectrum.
Electromagnetic spectrum is the arrangement of electromagnetic waves in the ascending order of frequency or descending order of wavelength.
When the waves are arranged in the ascending order of their frequency, then perfect order is given below as such -
Radio wave < Micro wave < Infrared wave < Visible light < U.V ray< X-ray < Gamma ray .
Hence, we see that radio wave has the least frequency, and gamma ray has the most frequency.
We know that wavelength and frequency are inversely are inversely proportional to each other. Hence, radio wave has more wavelength and less frequency.
The wave having more frequency is more energetic. Hence, gamma is more energetic and radio wave is less energetic .
OK.
But first we need to know . . .

Answer:
Carbon will act as backbone for organic molecules
Explanation:
Life is based on carbon; substances in organic chemistry where carbon is a key element is the organic chemistry analysis. The characteristics of carbon make it the cornerstone of organic molecules that make up living substances. Carbon can create really lengthy interlocking chains of C-C bonds. It helps carbon to form the foundation of carbon-containing organic compounds, the base of all established organic livelihoods.
Answer:
Structures are determined by two principal factors: the relative sizes of the ions and the ratio of the numbers of positive and negative ions in the compound.
