DMPQ- What are the different Steps of photosynthesis?

Steps of photosynthesis  Carbon dioxide in the atmosphere enters the plant leaf through stomata, i.e., minute epidermal pores in the leaves and stem of plants which facilitate the transfer of various gases and water vapor.  Water enters the leaves, primarily through the roots. These roots are especially designed to draw the ground water … Read more

DMPQ- List out the main Application of radioactivity.

Application of radioactivity: • Health: 1. Found extensive use in diagnosis and therapy eg. Phosphorous-32 is used to identify the cancerous cell. As cancer cell absorb more phosphorous, Iodine 131 is employ to determine cardiac output, plasma volume and fat metabolism and particularly to measure the activity of thyroid gland. 2. To treat cancer cells: … Read more

DMPQ-CNTs have unique thermal and mechanical properties that make them intriguing for the development of new materials. Discuss

Carbon nanotubes (CNTs) are cylindrical molecules that consist of rolled-up sheets of single-layer carbon atoms (graphene). They can be single-walled (SWCNT) with a diameter of less than 1 nanometer (nm) or multi-walled (MWCNT), consisting of several concentrically interlinked nanotubes, with diameters reaching more than 100 nm. Their length can reach several micrometers or even millimeters. … Read more

DMPQ- Explain the potential disadvantages of Transgenic crops.

A concern about what affect genetically modified material could have on human health. For example, transgenic crops have been suggested to cause allergies in some people, although it is uncertain whether transgenic crops are the source of this reaction. Furthermore the antibiotic resistance genes placed in these crops has been suggested to cause resistance to … Read more

DMPQ- Mention the uses and properties of Gaseous refinery products .

Gaseous refinery products include hydrogen, fuel gas, ethane, propane, and butane. Most of the hydrogen is consumed in refinery desulfurization facilities, which remove hydrogen sulfide from the gas stream and then separate that compound into elemental hydrogen and sulfur; small quantities of the hydrogen may be delivered to the refinery fuel system. Refinery fuel gas … Read more
