You go for another hike in the forest and wind up back at the same population of 100 flowering plants. you notice that one individual of the population grows in full shade, and all the others grow in at least partial sun. you take a leaf sample from the individual in the shade, sequence its dna, and notice that the individual is heterozygous. there is a mutation in the llt gene (the mutant is designated llt-s).what is the frequency of the llt-s allele in the population? a)1/100b)1/200c)1/1 (only one plant has it)d)it is not possible to determine from the information provided.

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
