The answer is; UV (ultraviolet)
The security pens use UV light to illuminate some marking on an object,such as a watermark, to identify its authenticity or owner. The markings are usually invisible to the naked eye under visible light. The marks are only visible when illuminated with UV light. This is because the marking is made of a fluorescent material that absorbs light of a shorter wavelength (this case UV) and emits a longer wavelength (this case visible light).
I think the propositions are :
Which organisms and set of characteristics are correctly paired?(1) fungi—carry out photosynthesis and heterotrophic nutrition(2) plants—carry out respiration and autotrophic nutrition(3) decomposers—carry out photosynthesis and autotrophic nutrition(4) animals—carry out autotrophic nutrition and heterotrophic nutrition
1): False because fungi do not have photosynthesis.
3) False because decomposers do not have photosynthesis.
4) False because animals do not have autotrophic nutrition.
2) is true because animal carries out respiration like other living organisms, and carry out autotrophic nutrition by photosynthesis.

Considering this info, and since we don't have any other clue about the mass of water we're talking about, I'd go for the B, is formed when water carries minerals into the ocean.</span>
Answer + Explanation :
1) Sperms have only one set of chromosomes i-e they are haploid while other cells are diploid.
2) Sperm cells come from embryo's gut while other cells can be found in blood , connective tissue , skin , bones etc.
3)Sperm cells are produced through meiosis while other cells are produced from mitosis.
4) Sperm cells are involved in reproduction while other cells have their specific functions in their specific locations.
5) Sperm cells are present is reproductive part or body while other cells are located everywhere.
6) Sperm cells originate from germ cells while other cells originate from stem cells.
7) Sperm cells are smaller then other cells of body.
8) Sperm cells are no more than a nucleus with small amount of cytoplasm and some mitochondrion while other cells follow normal symmetry.
