Answer: 3. researching the relationship between exposure to UV rays and skin cancer.
Applied research is an application based research as it utilizes the knowledge of scientific literature to solve the problems related to science. It is based upon the experimental procedure to find the cause of a natural phenomena.
Researching the ralationship between exposure to UV rays and skin rays. is the correct answer because it can be observed on the basis of experimental procedures the impact of UV under control conditions over the skin.
Carbon is a chemical element which exhibit an atomic mass of 12. It is a nonmetal. Carbon is the key ingredient which is present in all the organic molecules. As it is abundantly available in nature. It exists on earth in the form of solid, liquid and gas. It is present in the biomolecules such as fat, proteins and carbohydrates.
On the basis of the above explanation, the carbon is the element which is present in all organic compounds.
Option C, Carbon
Carbon is the most abundant non metal found in all organic matter. Be it protein, carbohydrates, fats, DNA, lipids or any any other organic compound, all have either simple or complex structures comprising of carbon molecule as a major building block.
In terms of organic chemistry , any molecule that has carbon as a central element along with several other elements such as hydrogen , nitrogen , phosphorus etc is an organic compound. Carbon is a versatile element and is able to form four covalent bonds. These properties make it more preferable element for organic substances.
Hence, option C is correct
The answer would be several broken plates in motion.
The answer is several broken plates
Because my test said so
option A, is the best technique for sampling the ocean floor
Ocean coring is a process in which sample of sea floor sediment is taken and studied to understand its composition. it is a common practice during the petroleum production from sea floor and hence is known as ocean sediment coring.
Usually a cylindrical sample is extracted beneath the sea floor by dropping a cylinder through the water. The sedimentary sample collected show the deposition of sediment (variation) with due course of time.
hence , option A is correct
Monocytes are the white blood cells that are found in almost all tissue in the human body. Monocytes move into tissues and engulf and digest cells and foreign substances in a process known as phagocytosis. After monocytes have ingested cells, hydrolytic enzymes that destroy pathogens is being secreted by lysosomes within the monocytes.
