Are the layers still horizontal or are they bent Why? Answer. Answer: Figure 10.6: Rocks that were originally deposited in horizontal layers can subsequently deform by tectonic forces into folds and faults. Folds constitute the twists and bends in rocks. How is horizontal unconformity formed? An angular unconformity is an unconformity where horizontally parallel strata […]
What is the main cause of ozone depletion?
What is the main cause of ozone depletion? Ozone depletion occurs when chlorofluorocarbons (CFCs) and halons—gases formerly found in aerosol spray cans and refrigerants—are released into the atmosphere (see details below). CFCs and halons cause chemical reactions that break down ozone molecules, reducing ozone’s ultraviolet radiation-absorbing capacity. Is inhaling ozone bad? Whether in its pure […]
What are all the structures in cytoplasm?
What are all the structures in cytoplasm? It is mainly composed of water, salts, and proteins. In eukaryotic cells, the cytoplasm includes all of the material inside the cell and outside of the nucleus. All of the organelles in eukaryotic cells, such as the nucleus, endoplasmic reticulum, and mitochondria, are located in the cytoplasm. Which […]
What is the line of symmetry on a graph?
Why do I feel like passing out when I poop?
Why do I feel like passing out when I poop? But straining lowers the volume of blood returning to the heart, which decreases the amount of blood leaving it. Special pressure receptors in the blood vessels in the neck register the increased pressure from straining and trigger a slowing of the heart rate to decrease […]
How do electrolytic cells work?
How do electrolytic cells work? An electrolytic cell converts electrical energy into chemical energy. Here, the redox reaction is spontaneous and is responsible for the production of electrical energy. The reaction at the anode is oxidation and that at the cathode is reduction. Here, the anode is positive and cathode is the negative electrode. What […]
What chemicals are needed for muscle contraction?
What chemicals are needed for muscle contraction? In order to perform the mechanical work of contraction, actin and myosin utilize the chemical energy of the molecule adenosine triphosphate (ATP). What are two ways that calcium is needed for muscle contraction to occur be specific? (1) Calcium binds to troponin C, causing the conformational shift in […]
Are rocks stronger under tension or compression?
Are rocks stronger under tension or compression? Rock is strong under compression but relatively weak under tension and shear. This is a result of the microscopic structure of rock: it contains microscopic cracks which are forced open and enlarged by tension and shear but which are forced closed by compression. What increases rock strength? The […]
What happens when a solid is dissolved in a liquid?
What happens when a solid is dissolved in a liquid? In the simplest case it involves mixing two materials together. The most common examples of dissolving involve a solid and a liquid, usually water. When a solid dissolves the solid (solute) and the liquid (solvent) form a very close intimate mixture called a solution. Why […]
What is the function of science and technology in development?
What is the function of science and technology in development? The role of S is to lead national development and to support socio-economic needs. The priority areas that have been identified are: – Development of electronics, information, and communication technologies. – Development of selected high technologies to lead the industrial structure adjustment. Is there a […]
