Answer:
45.45 ml of dimethyl sulfoxide
Explanation:
density of dimethyl sulfoxide is 1.10 g/10⁻³L which is 1.10 g/mL
now we devise the next reasoning:
If 1.10 g of dimethyl sulfoxide have a volume of 1 mL
Then 50 g of dimethyl sulfoxide have a volume of X mL
X = (50 × 1) / 1.10 = 45.45 ml of dimethyl sulfoxide

Answer:
The answer is D. New African violet plants can grow from leaves cut off of existing
Keeping your arm straight in front of you, you rotate 90° to your left, and see the left side of the circle lit while the right side is dark. Half the ball is still lit up, but you can see only part of the lit area. As you continue to rotate, you see a different amount of the ball.
Explanation:
Scientific evidences abound of the occurrence of plastic pollution, from mega- to nano-sized plastics, in virtually all matrixes of the environment. Apart from the direct effects of plastics and microplastics pollution such as entanglement, inflammation of cells and gut blockage due to ingestion, plastics are also able to act as vectors of various chemical contaminants in the aquatic environment. This paper provides a review of the association of plastic additives with environmental microplastics, how the structure and composition of polymers influence sorption capacities and highlights some of the models that have been employed to interpret experimental data from recent sorption studies. The factors that influence the sorption of chemical contaminants such as the degree of crystallinity, surface weathering, and chemical properties of contaminants. and the implications of chemical sorption by plastics for the marine food web and human health are also discussed. It was however observed that most studies relied on pristine or artificially aged plastics rather than field plastic samples for studies on chemical sorption by plastics.
