Answer:
The pneumatization of avian bones allows them to be much more efficient with respiration and provide an extraordinary amount of strength compared to their weight. This connection of air sacs to the bone does cause some complications if the bone is damaged or broken.
Answer:
Air moves into the lungs from atmosphere
Explanation:
As per the gas law, pressure of a gas is indirectly proportional to the volume of the gas. Thus, if volume increases pressure decreases.
Here, the volume of alveoli has increased due to which the pressure within the alveolar space reduces such that the atmospheric pressure outside alveoli becomes higher than the alveolar pressure within the alveoli. Due to this difference in pressure, the air gushes into the lungs.
Answer:
you could calculate the speed of a snail or a cheetah by measuring a distance and measuring the time it takes them to get there. direction would be considered if you were finding velocity.
Explanation:
Fatty acids are building blocks of lipids. The correct option is A.
Fats and oil are known as lipids.
Lipids are part of the classes of food which are made up of high proportion of carbon and hydrogen with very little oxygen.
Fats are solids and oils are liquids at room temperature. They serve the following functions to the body:
- They provide the body with energy
- They are solvents for fat-soluble vitamins and hormones.
Before lipids can be absorbed into the body, they must be broken down into fatty acids and glycerol.
Therefore, fatty acids are building blocks of lipids.
