Which is the best indicator of a population's health and nutritional status? a) number and causes of death b) gender of newborn babies c) number of government food programs d) number of low-birth weight infants

D) number of low-birth weight infants

Explanation:

The number of babies with low birth weight makes it possible to make inferences of the health and nutrition of a population if, for example, many children with low birth weight are born, it is inferred that mothers have not had a diet based on the resources necessary for healthy growth of the fetus , in the same way if a baby is born with low weight it is very likely that during his life he presents several diseases as well as his offspring.

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.
