Light is a form of EM radiation.
EM radiation has no mass (it's just energy packets called photons).
EM radiation can travel through a vacuum. (The speed of light in a vacuum is called c and is around 300,000 m/s).
Hope this helps!
Answer:
deoxyribonucleotides consist of a nitrogenous base and a pentose sugar with the nitrogenous bases covalently bonded to make the primary structure
Explanation:
A deoxyribonucleotide is a nucleotide that consists of a nitrogenous base (i.e., purine or pyrimidine) that binds to deoxyribose (i.e., a pentose sugar-containing five carbon atoms), and one phosphate group attached to the nitrogenous base. In the DNA, there are four types of nitrogenous bases: two purines (Adenine and Guanine), and two pyrimidines (Cytosine and Thymine). All these bases are attached to 1' carbon (C1') of deoxyribose by a glycosidic bond. A nucleoside is a nitrogenous base linked to ribose (in RNA) or deoxyribose (in DNA).
Answer:
It is well known that the three main sources of demographic and social statistics are censuses, surveys and administrative records. These three data sources are the principal means of collecting basic demographic and social statistics as part of an integrated programme of statistical data collection and compilation.
Explanation:
Answer:
In a population, a specific gene has two alleles, 'A' and 'a.' Individuals with
genotype 'aa' die in early childhood. Individuals with genotype 'Aa' have a
higher rate of surviving and reproducing than individuals with genotype 'AA.'
This phenomenon is called survival of the fittest, Darwins law which entails the fittest organisms survives while the ones that could not would go into extinction
