Answer:
When you inhale, muscles increase the size of your thoracic (chest) cavity and expand your lungs. This increases their volume, so pressure inside the lungs decreases. As a result, outside air rushes into the lungs. That's because a gas always flows from an area of higher to lower pressure.
Plants do not breathe, they only respire. No such respiratory organ os present in plants. The carbon dioxide produced in animals during respiration is released to the atmosphere, whereas the carbondioxide produced during plant respiration may be used by the plant for carrying out photosynthesis.
A
The Earths axis is tilted approximately 23.5 degrees (which is the reason the Earth experiences seasons).
The correct answer is filtration.
The small molecules can cross in and out of the capillaries through facilitated or simple diffusion. However, the majority of the flow of capillary and tissue fluid takes place through the process of filtration and reabsorption. Filtration refers to the movement of the fluid out of the capillaries and is mediated by the capillary hydrostatic pressure.
Answer:
The flooding of half part of the forest have successful separate the population of frogs in that ecosystem into two different set of frogs. This is an example of allopatric speciation, that is, the population become separated as a result of geographical barrier. This separation will make the two set of frog population to become new species. On the long run, the two species may become unable to relate sexually.
