Lava that hardens on the surface is called an extrusion. The rock layers below an extrusion are always older than the extrusion. ... There, the magma cools and hardens into a mass of igneous rock called an intrusion. An intrusion is always younger than the rock layers around and beneath it.
Answer:
Hypotonic solutions are those with less solute (again read as higher water potential). Isotonic solutions have equal (iso-) concentrations of substances. Water potentials are thus equal, although there will still be equal amounts of water movement in and out of the cell, the net flow is zero.
Answer:
strong acidic
Explanation:
the ph of solutions 10-8 is strongly acidic according to the ph scale hence a solution with [H+] of 10-8 is strongly acidic
Answer:
F = dominant, free earlobes
f = recessive, attached earlobes
father is "ff" then he has only two recessive attached earlobe alleles meaning he can only have attached earlobes. This is his phenotype, the visible trait produced by the genotype.
The mother is said to be "Ff". She has one dominant free earlobe allele (F) and one recessive attached allele (f). The dominant allele gets expressed as the visible trait (phenotype). = free earlobes
