The number in the station’s upper right is the air pressure, which is measured in millibars (mb). The circle symbol indicates the percentage of cloud cover, as shown in the table at right. Use the information above to complete this table for station A on the Gizmo.
Mass at start was 100 g, decreased to 96 g due to oxygen lost (1). ii Half this mass = 2 g (1). This loss in mass occurs by (approximately) 0.5 minutes / 30 seconds (1). iii At the start there are a lot of enzyme and substrate molecules, so there are a lot of successful collisions (1). As the reaction proceeds, the

18 cze 2022 · (b) The availability of oxygen in the air is lower at high altitudes because of the lower air pressure. Populations of humans that have lived at high altitude for many generations have adapted to these conditions. One adaptation these people have is a larger thorax than people living at lower altitudes. A student made the following hypothesis:
Generally, there are two types of flight adaptations in birds: Morphological Adaptations. Anatomical Adaptations. Morphological Adaptations Body Contour. The birds have a spindle-shaped body to offer less air resistance during flight. This helps the birds to conserve energy and become more efficient at flying. Compact Body
Alveoli have thin walls and a large surface area. The concentration of oxygen in the blood is higher than in the alveoli. 10 The diagram illustrates changes in air pressure taking place inside the lungs during a complete cycle of breathing. Atmospheric pressure is 101 kPa.
