The most used instruments for the determination of free-living physical activity and energy expenditure are; whole-room indirect calorimeter, Accelerometers and pedometers and also the Doubly-Labeled Water. Indirect calorimetry measures gas exchange from which energy expenditure can be estimated, Double labeled water is the most relevant method for measuring free-living energy expenditure in animals and humans, it is based on exponential disappearance from the body of the stable isotopes (H and O) after a bolus dose of water. Accelerometers and pedometers provide an inexpensive overall measure of physical activity, however they are unable to asses the intensity, frequency and duration of activity or to estimate energy expenditure.
Answer:
A green ball is used for the sets which were then replaced with CGI with a human
using cars that get lower gas mileage
Answer: The percentage of the helium will increase with the decrease in the percentage of the hydrogen.
Explanation:
The conversion of the hydrogen into helium occurs by the nuclear fusion of the hydrogen atoms. This process reduces the hydrogen density and reduces the energy production inside the core region. Typically, in the core region of the hydrogen is converted into the helium by nuclear fusion. Four hydrogen atoms are collectively fuse to form one atom of helium. This process involves the production of heat energy.
1. Passage of a sperm through the corona radiata of the oocyte.
2. Penetration of the zona pellucida.
3.Fusion of the plasma cell membranes of the oocyte and sperm. after fusion the sperm head and tail enters the oocyte but plasma membrane of sperm doesn't.
4. Completion of the second meiotic division of the oocyte. this creates female pronucleus and polar body 2.
5. Formation of the male pronucleus (nucleus of sperm enlarges)
6. Breakdown of the pronuclear membranes and restoration of diploid number of chromosomes.
