Naphthol AS-D chloroacetate esterase (specific) is usually positive in <u>Granulocytic</u> cells, and alpha naphthyl acetate esterase (nonspecific)is useful for identifying blast cells of <u>monocytic</u> lineage.
- White blood cells known as granulocytes have tiny granules. Proteins are present in these granules.
- Granulocytes can be classified as neutrophils, eosinophils, or basophils. The body uses granulocytes, particularly neutrophils, to fight bacterial infections.
- A monocyte is a subtype of phagocyte and a type of white blood cell.
- The role of the monocyte-macrophage cell lineage in acute and chronic allograft immunopathology is becoming more widely acknowledged.
- It is linked to lower graft performance and survival when this lineage of cells predominates in tissue that is rejecting an allograft.

Cigarette smoking and environmental chemicals
Tobacco smoke and certain environmental chemicals are known carcinogens (substances that can cause cancer in living tissue). The tobacco smoke from cigarette smoking contains harmful chemicals such as hydrogen cyanide, arsenic, ammonia, benzene, and many more. In fact, from 2009 to 2013, three out of 10 cancer deaths in the U.S have been attributed to cigarette smoking or exposure to tobacco smoke.
The statement 'many scientists helped developed it over many decades' describes the development of our understanding of DNA and inherited traits.
<h3>What is the DNA?</h3>
Deoxyribonucleic acid or DNA is a double helix molecule that stores the genetic information inherited across generations.
This molecule (DNA) contain genes and regulatory sequences that indicate the specific proteins an organism can produce.
In conclusion, the statement 'many scientists helped developed it over many decades' describes the development of our understanding of DNA and inherited traits.
Complete Question:

- B. Many Scientists helped develop it over many decades.
- C. Frederick Griffith figures it all out in 1928.
- D. One scientist working alone discovered it over a few years

Patrick has to learn the correct way to jump rope for his boxing match. Since he already knew how to jump rope, learning the correct way would be called transfer. The correct answer is D.
Answer: It is called Marine snow.
Explanation:
Marine snow is the particulate matter that originate from the ocean. It is formed by collisions and combinations larger molecules(macromolecules) on surface water which later settles at the bottom. Marine snow may also be formed from decaying organic materials such a salp calony and house of a larvacean. Marine snow contains larger molecules of microorganism and protistans.
