Answer: 92 Chromatids
Explanation: A chromatid is one of the two strands that form when a chromosome duplicates itself during cell division. Before DNA replication, the somatic cell has 46 chromosomes. Subsequently after the DNA replication, each chromosome will possess two physically attached sister chromatids, the chromosomes will condense to form compact structures (though it'll still be made of two chromatids). Thus, after replication, there would be 92 chromatids.
The concept of the photon emerged from experimentation with thermal radiation, electromagnetic radiation emitted as the result of a source’s temperature, which produces a continuous spectrum of energies.The photoelectric effect provided indisputable evidence for the existence of the photon and thus the particle-like behavior of electromagnetic radiation. However, more direct evidence was needed to verify the quantized nature of energy in all matter. In this section, we describe how observation of the interaction of atoms with visible light provided this evidence
The organism listed that is correctly with its metabolism is;
Human-heterotroph
Heterotrophic mode of nutrition is a type of nutrition in which organism depend upon other organisms to survive. Mainly non-green plants and all animals including humans are heterotrophic. These organisms have to acquire and take in all the organic substances they need to survive.
