Is DNA a blueprint? DNA is called the blueprint of life because it contains the instructions needed for an organism to grow, develop, survive and reproduce. DNA does this by controlling protein synthesis. Proteins do most of the work in cells, and are the basic unit of structure and function in the cells of organisms. […]

What is molecule Short answer? A molecule is defined as two or more atoms of the same element different element that are bound together. A molecule may be homonuclear, which means, it consists of atoms of one chemical element, as with oxygen (O2); or it may be heteronuclear, a chemical compound composed of more than […]

What will the atmosphere be like in 2025? They found that by 2025, atmospheric carbon dioxide (CO2) levels will very likely be higher than they were during the warmest period of the last 3.3 million years. Dr. A striking result we’ve found is that the warmest part of the Pliocene had between 380 and 420 […]

Does pressure affect mass flow rate? Doubling the line pressure halves the volumetric flow rate, and decreasing line pressure increases the volumetric flow rate. However, the number of molecules of air that flow (mass flow rate) does not change. What is the relation between pressure and area? The relation between pressure and area is that […]

Is dropping out a good idea? Is it a good idea to drop out of high school? No, it is not a good idea to drop out of high school. Most people do not live happy, fulfilling lives without a high school diploma. In fact, the data show that most dropouts live in poverty that […]

What is the most important part of the electromagnetic spectrum? Infrared (IR) radiation – also referred to as thermal radiation – is the portion of the electromagnetic spectrum lying between visible light and microwaves. The most important natural source of infrared radiation is the sun. What is the order of increasing wavelength? The electromagnetic spectrum […]

What does Saturn stand for? “Saturn is about maturity, responsibility, discipline, and stewardship,” says Jennifer Freed, PhD, psychological astrologer and author of Use Your Planets Wisely. “Look at each sign and what it means to be mature using its archetypal energy.” What does Saturn mean spiritually? Saturn is associated with the higher chakras and specifically […]

What are 2 types of kinetic friction? In general, the friction is of the following two types: (1) Static friction. It is the friction, experienced by a body, when at rest. (2) Dynamic friction. It is the friction, experienced by a body, when in motion. (a) Sliding friction. (b) Rolling friction. (c) Pivot friction. 14.7. […]

How can we reduce CO2 in the atmosphere? Here are six options for removing carbon from the atmosphere: 1) Forests. 2) Farms. 3) Bio-energy with Carbon Capture and Storage (BECCS) 4) Direct Air Capture. 5) Carbon Mineralization. 6) Ocean-based Concepts. The Future of Carbon Removal. How is carbon dioxide returned to the atmosphere? Returning carbon […]

What is the law of vector algebra? Vector algebra in geometric form Two vectors u and v are equal if they have the same magnitude (length) and direction. The Negative of a Vector The negative of the vector u is written -u, and has the same magnitude but opposite direction to u. If u = […]
