Essentially, when you breathe in the lung take in oxygen and pass it along to the bloodstream, which brings it to your bodies cells. In return it picks up carbon dioxide, which the lungs dispose of. Every time you breathe this process is happening. That is why it's crucial to keep your lungs healthy.

I think the answer would be to to write observations about what the sky looks like or to count the number of visible stars in the sky.
In geology, a graded bed is one characterized by a systematic change in grain or clast size from one side of the bed to the other. Most commonly this takes the form of normal grading, with coarser sediments at the base, which grade upward into progressively finer onesI just learned about this in our rocks and minerals unit for science,
Answer:
1.To prepare compost, either a plastic or a concrete tank can be used. The size of the tank depends upon the availability of raw materials.
Collect the biomass and place it under the sun for about 8-12 days. Now chop it to the required size using the cutter.Prepare a cow dung slurry and sprinkle it on the heap for quick decomposition.Add a layer (2 – 3 inch) of soil or sand at the bottom of the tank.Now prepare fine bedding by adding partially decomposed cow dung, dried leaves and other biodegradable wastes collected from fields and kitchen. Distribute them evenly on the sand layer.Continue adding both the chopped bio-waste and partially decomposed cow dung layer-wise into the tank up to a depth of 0.5-1.0 ft.After adding all the bio-wastes, release the earthworm species over the mixture and cover the compost mixture with dry straw or gunny bags.Sprinkle water on a regular basis to maintain the moisture content of the compost.Cover the tank with a thatch roof to prevent the entry of ants, lizards, mouse, snakes, etc. and protect the compost from rainwater and direct sunshine.Have a frequent check to avoid the compost from overheating. Maintain proper moisture and temperature.

The correct answer is E. Vertebrates are all related to a common ancestor
Explanation:
According to biology and evolution, organisms from different species but that share similarities in morphology (body structures) as well as in genetics often have a phylogenetic relationship which means they descend from the same organism or share a common ancestor. This applies to multiple taxonomical levels including classes such as mammals or birds as it has been proved each of this derived from a common ancestor. Therefore, the similarity in the body structure (morphology) in all mammals suggest vertebrates are related to a common ancestor and as they evolved from this, they share similarities not only in terms of morphology but also in genetics.
