What factors facilitate erosion by wind? a. heat, low water table and low humidity
b. ocean currents, La Niña and El Niño
c. drought, plant die-off and wind
d. increased solar flares, close solar orbits and sunspots

because the light is a great source of energy for the plants to survive. (i hope this )

any abiotic or biotic factor in an ecosystem that causes a population's size to slow or decrease is a limiting factor.

ans.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
