Answer:
Birds require high levels of oxygen and, therefore, high rates of gas exchange due to flight demands. Avian resting oxygen consumption is high compared to that of mammals and other vertebrates, and this increases even more during the flight.
Explanation:
Compared to mammals, birds have specific adaptations of the respiratory system that result in higher levels of oxygen exchange.
Answer:
The correct answer is - option B. ducks and swine.
Explanation:
Influenza virus is capable of the genetic reassortment. This reassortment involves the reassortment of genetic parts in between two influenza strain. This takes place due to the ability of influenza virus to alter or modify the structure of Hemagglutinin (HA) and neuraminidase.
Some other characters also helps them to develop different strains for different host such as mutation, antigenic drift and many other conditions. Influenza virus subtype A are belongs to the avian host so they affect the birds such as duck, swan, gesse. Other than avian variants there is another strain that affect pigs known as swan variants. These strains are virulent if reassorted with human strains.
Thus, the correct answer is - option B.
Answer:
<em>Steps of photosynthesis:</em>
<em></em>
Step 1: Energy is captured from sunlight.
Step 2: Light energy is converted to chemical energy,
which is temporarily stored in ATP and the energy
carrier molecule NADPH.
Step 3: The chemical energy stored in ATP and NADPH
powers the formation of organic compounds, using carbon
dioxide (CO2
).
