The many branches leading into the human lungs become smaller until they end in small sacs called alveoli. Each alveolus is surrounded by a net of tiny capillaries.
How does the finely branched structure of the capillary nets relate to their function in the respiratory system?
A. The branching capillaries allow the flowing blood to warm all of the surfaces of the alveoli.

B. The branching capillaries attach to the walls of the alveoli to keep them expanded and full of air.

c The branching capillaries Join bundles of alveoll together and keep them separated from other bundies.

D. The branching capillaries provide many points where the capillaries and alveoli touch and exchange gases.

yes it is   dangerous

explanation:

because that foot is discusting and could get you sick

weathering - colorado river carves land in arizona to form the grand canyon. cracks form in a sandstone wall surrounding a house. a marble statue near the science museum is changing color due to rainfall

erosion - after a rainstorm, soil and rock piees litter the roadways. the sand dunes in the sahara desert are changing shape.

here's your answer.

answer: zinc is the substance which has a volume of 1.38 .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e.

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula .

hence, the volume of aluminium will be = which comes out to be 1.703 .

similarly, volume of zinc, chromium, and nickel will be 1.378 , 0.869 , and 0.356 respectively.
