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:
Fluid friction
Explanation:
It is known as drag force it cant be static friction because it cant move cant be rolling friction because its not rolling its in the sky its not sliding friction because its not going down a hill or a slide

Answer:
vaccine
bacteria
pathogens
cells
toxins
antibiotics
Explanation:
Bacterial meningitis is a serious disease that is caused by an infection which results into Inflammation of brain and spinal cord membranes.
It is generally caused by virus but also caused by fungus and bacteria. A vaccine is required to fight against the bacterial meningitis. Symptoms include fever, stiff neck and headache. This disease is carried by the bacteria present in the throat of infectious person and can transmit through coughing, sneezing and kissing. The bacteria are the pathogens, releases a toxin which destroy cells and surface components of nervous system.
This disease is treated with intravenous antibiotics and corticosteroids (sometimes).
Hence, the correct answers for blanks are vaccine, bacteria, pathogens, cells, toxins, and antibiotics in sequential order.
Answer:
Option (B)
Explanation:
A river that is diverted to the irrigating farmland during a drought is an example of the human-caused disturbances to an ecosystem.
An ecosystem refers to a particular community within which the organisms exist and interact with each other. For example, fresh water ecosystem, desert ecosystem and forest ecosystem.
In the given situation, the river channel is disturbed by changing its flow direction. This is caused by the human activity, that changes the course of the river channel to the farmlands during a flood, so that the water can provide nutrient to the soil and prevent the soil from getting eroded.
Thus, by doing this, the river ecosystem gets affected, as a result of which the organisms existing in this ecosystem such as fishes are affected.
Hence, the correct answer is option (B).
