Answer:
Your answer would be "B) They pass oxygen from the air into the blood."
Explanation:
They certainly don't coordinate the movement of the heart, so A isn't an option.
The lungs also don't pump blood through the body, that's the hearts job.
And the lungs do not filter carbon out of the air, which eliminates D.
Therefore your answer is B.
The lungs function in the human body by passing oxygen from the air into the blood.
Gaseous exchange in the lungGaseous exchange happens in the lung of humans. Oxygen is exchanged for carbon dioxide.
A mixture of air is taken through the mouth and the nose into the lung. On getting to the lung, the oxygen in the air dissolves on the surface of the lung and enters the blood by diffusion.
In exchange, carbon dioxide in the blood diffuses in the opposite direction and is breathed out.

what ways do we use patterns of classification in science? give examples
Answer:
Classification is the way scientists use to categorize and organize all of life. It can help to distinguish how similar or different living organisms are to each other
Explanation:
Patterns are used in science to classify objects or phenomena into groups. There are patterns of both similarity and difference.
What is classification?Classification is the way scientists use to group and categorize objects, phenomenon or life forms. It can help to distinguish how similar or different living organisms are to each other based upon the pattern of their structure and organization.
Patterns are regular and intelligible forms , sequences, or structure that found throughout nature. Scientific questions may be generated when scientists observe a pattern of events or when something does not match an established pattern.
For example, the frozen water in an iceberg is arranged into a regular, repeating crystal structure—a pattern of similarity. Young children can observe a common pattern of difference, the differences between adult animals and their offspring.
Thus, it is clear from above explanation, the ways to use patterns of classification in science.

The role of both factors within a nutrient cycle is very important because nutrients cycling through biotic and abiotic systems constantly.
Explain the role of both biotic and abiotic factors within a nutrient cycle?Plants, animals, microorganism and organic matter are the biotic locations of nutrients while on the other hand, the atmosphere, water, and soil represent the abiotic locations. Nutrients are constantly moving or cycling through biotic and abiotic systems.
So we can conclude that the role of both factors within a nutrient cycle is very important because nutrients cycling through biotic and abiotic systems constantly.

Describe the flow of energy to the lion using a food chain from the food web that includes a rabbit.
Answer:
10%
Explanation:
the sun gives energy to the grass (to make it easier to understand, say the sun gives 100un of energy to the plants)
from there, the rabbit eats the grass( 10% of 100 is 10, so the rabbit gets 10un of energy)
and the, a lion eats the rabbit (10% of 10 is 1, so the lion gets 1 un of energy)
every single time a predator consumes prey, it only gets 10% of what the prey gets from its prey.
