Which is the strongest heart valve? The left ventricle is the largest and strongest chamber in your heart. The left ventricle’s chamber walls are only about 1.0 to 1.3cm, but they have enough force to push blood through the aortic valve and into your body. How does the blood get around the body? Two types […]
What does the 84 in krypton 84 mean?
What is the difference between dynamics and kinematics?
What is the difference between dynamics and kinematics? Traditionally, motion studies have been divided into two categories: kinematics and dynamics. Kinematics is the study of motion without regard to forces that cause it; dynamics is the study of motions that result from forces. What are kinematic properties? To describe motion, kinematics studies the trajectories of […]
Does lowering a car increase drag?
Does lowering a car increase drag? Lowered vehicles are more aerodynamic. There’s less air hitting the wheels and tires (that are not streamlined shapes). This makes these cars faster. BUT, lowering a car too much will actually increase wind drag. Why is it important to reduce vehicles drag? Automotive manufacturers are placing a growing emphasis […]
What enzyme digests proteins?
What enzyme digests proteins? The enzyme pepsin plays an important role in the digestion of proteins by breaking down the intact protein to peptides, which are short chains of four to nine amino acids. In the duodenum, other enzymes— trypsin, elastase, and chymotrypsin—act on the peptides reducing them to smaller peptides. Where does the digestion […]
Is Jade worth money?
Is Jade worth money? As one of the most expensive gems in the world, it can sometimes be priced at millions of dollars. The second most expensive form of jade is that which exhibits a lavender hue. This color will be more expensive than other types of non-Imperial green jade, such as those with a […]
Why are healthy root nodules pink in Colour?
Why are healthy root nodules pink in Colour? The pink color is from leghemoglobin, a protein that carries oxygen—similar to the hemoglobin in human blood. The nitrogenase enzyme involved in N fixation is sensitive to oxygen and the leghemoglobin helps reduce oxygen concentrations in the area of the nodule where the nitrogenase enzyme is active. […]
How are electric charges created?
How are electric charges created? A. Electrons can be removed from atoms and accumulated to produce a negative charge. Atoms from which electrons have been removed produce positive electric charge. … What is range of electric force? The electric force is operative between charges down to distances of at least 10-16 metre, or approximately one-tenth […]
How do plants return water back into the environment?
How do plants return water back into the environment? Plants soak up large amounts of water through their roots. The water then moves up the plant and evaporates from the leaves in a process called transpiration. The process of transpiration, like evaporation, returns water back into the atmosphere. What’s it called when plants lose water […]
Can you use a 50mm lens for macro?
Can you use a 50mm lens for macro? 50mm lenses work best in capturing typical macro shots. However, these types of macro lenses have their drawbacks. 50mm lenses make subjects appear half “life-size” since they usually feature a 1:2 ratio, and require shooting at a much closer distance. But a 50mm lens is a must […]
