Answer:
D. / 4 - Phosphorescents
Explanation:
Phosphorescence occurs when light is absorved by a material, and when the material is in the dark we can see how radiation is emitted from the object, in the form of light. Phosphorescent materials are called phosphorescents.
Facts/notes:
- This does not occur immediately
- It occurs from a longer time than fluorescence (because electrons take longer to slow down their movement)
- It is a photoluminescence
- Remember that bioluminescence is not strictly related to phosphorescence. It's a type chemiluminescence.
- For a more detalied understaning you should read about excitation, types of excitation and how this causes/affects phosphorescence.

Answer:
A
Explanation:
Radioactively labelled amino acids will be found in the ribosomes. These are the organelles that are the site of protein synthesis.
Amino acids are taken up into the cytoplasm from the surrounding cell culture medium. Amino acids are then bound to tRNAs (with the enzyme aminoacyl-tRNA synthetases) and taken to the ribosome, where they are assembled into a polypeptide chain by the translation machinery.
Tadpoles has gills ...and after metamorphosis frog gets lungs and an additional skin / cutaneous respiration !
so answer is A
Answer:
Protista, Plantae
Explanation:
Protists are a diverse group of organisms with microscopic and unicellular cell structure. It includes the plant-like protists (algae), the animal-like protists (protozoans) and fungi-like protists.
Earlier Algae was classified as protista but they were unable to represent evolutionary relationship accurately and the classification was insettled. Modern taxonomy has rearranged the group and placed it under kingdom plantae on the basis of mode of nutrition is naturally autotrophic mode and mode of reproduction can be either asexual mode or sexual mode or vegetative mode.
Hence, the correct answer is Protista and Plantae in sequential order.
