How do oceans influence climate? The oceans influence climate by absorbing solar radiation and releasing heat needed to drive the atmospheric circulation, by releasing aerosols that influence cloud cover, by emitting most of the water that falls on land as rain, by absorbing carbon dioxide from the atmosphere and storing it for years to millions […]
Can you donate 2 pints of blood a day?
Can you donate 2 pints of blood a day? Red blood cells are the most frequently used blood component and are needed by almost every type of patient requiring transfusion. If you meet certain criteria, Power Red allows you to safely donate two units of red cells during one appointment as an automated donation process. […]
How long is the human circulatory system?
How long is the human circulatory system? The circulatory system in the human body stretches 66,000 miles, more than two and a half times the circumference of the Earth. What is the main function of blood? Blood has many different functions, including: transporting oxygen and nutrients to the lungs and tissues. forming blood clots to […]
What happens to water when it freezes its mass INcreases?
What happens to water when it freezes its mass INcreases? The fact that water expands upon freezing causes icebergs to float. The fact that water reaches a maximum density at about 4°C causes bodies of water to freeze on the top first. The expansion upon freezing comes from the fact that water crystallizes into an […]
What does a 100 watt bulb mean?
How is beat perceived by human ear?
How is beat perceived by human ear? Binaural-beat perception originates in the inferior colliculus of the midbrain and the superior olivary complex of the brainstem, where auditory signals from each ear are integrated and precipitate electrical impulses along neural pathways through the reticular formation up the midbrain to the thalamus, auditory cortex … Can you […]
What happens when you put a straw in a glass of water?
What is an example of a closed system in thermodynamics?
What is an example of a closed system in thermodynamics? A closed system allows only energy transfer but no transfer of mass. Example: a cup of coffee with a lid on it, or a simple water bottle. Isolated systems allow neither mass nor energy to flow through their boundaries. Example: a thermos flask. Which of […]
How do deep sea producers differ from other producers?
How do deep sea producers differ from other producers? Deep-sea producers have adapted mechanisms to conduct photosynthesis with less visible light. Deep-sea producers have adapted to conduct respiration instead of photosynthesis due to lack of light. Is ocean bacteria a producer? Phytoplankton serve as the major primary producers in the marine ecosystem. These microscopic, single-celled […]
Does a heavier person slide faster?
Does a heavier person slide faster? The force due to gravity and frictional force are both proportional to the mass of the person so mass cancels out. Just because no one’s mentioned it yet, more mass would mean larger terminal velocity, so at peak speed heavier people will go down slides faster. Do heavier riders […]
