Answer:
D. There isn't enough information to determine which is the coding strand
Explanation:
In this protein, it would be necessary to observe a start codon (ATG) and one-stop codon (either TAA, TAG, or TGA) which should be separated by six (6) intern codons. It is not observable this nucleotide sequence in any of both DNA strands.
Dependent on both the mineral assemblage of the protolith and the temperature and pressure of formation...
Or
both minteral content of the prolith and the temperature and pressure formation..
I really don't know my answer wrong or right....if it's wrong pls forgive me....
Answer:
they give the lungs a really big surface area. they have moist, thin walls (just one cell thick) they have a lot of tiny blood vessels called capillaries.
The walls of the alveoli are only one cell thick. This makes the exchange surface very thin - shortening the diffusion distance across which gases have to move. Each alveolus is surrounded by blood capillaries which ensure a good blood supply.Adaptations of the alveoli:
Thin walls - alveolar walls are one cell thick providing gases with a short diffusion distance. Moist walls - gases dissolve in the moisture helping them to pass across the gas exchange surface. Permeable walls - allow gases to pass through.
