Answer:
is the surface where the water pressure head is equal to the atmospheric pressure
Explanation:
is the upper surface of the zone of saturation. The zone of saturation is where the pores and fractures of the ground are saturated with water.
Answer:
Relative dating is the technique to calculate the age of an ancient materials in comparison to another material's age. Layer A is less older, if layer B lies beneath it. Layer A may be 2.5 to 3 million years old.
Explanation:
Before discovery of radioactive carbon dating method, geologists make use of relative dating method in order to determine the age of rock or fossils. The relative dating procedure often referred to as stratigraphy. Though this procedure is not capable of predict absolute age or dating. In relative dating, is mainly based on the fact that the older rock layers will be deeper in respect to the less older rock layer.
The correct answer is parasitism.
Parasitism, in the field of evolutionary biology, refers to an association between species, where the parasite, the organism, lives on or in another species, the host, creating some kind of harm in it, and is amended structurally to this way of life.
The parasites include protozoans, like as the agents of sleeping sickness, malaria, and amoeba dysentery; animals, like lice, hookworms, mosquitoes, and vampire bats; fungi, like the agents of ringworm, honey fungus; and plants, like dodder, mistletoe, and the broomrapes.
Answer:
True
Explanation:
A gene pool is all of the genes present in a particular population. Each type of gene within a gene pool may exist in one or more alleles. The prevalence of an allele within the gene pool is described by its allele frequency. ... If it is polymorphic, each allele has a frequency that is between 1 and 99%.
