Crystalline silica is a natural compound in the earth's crust and is a basic component of sand and granite. Silicosis is an incurable disease of the lungs caused by breathing crystalline silica dust. This dust can cause scar tissue to form in the lungs.
Answer:
1250 g=1.25 Kg
Explanation:
We are given that Jason has five fishes of equally massed lead fish weights.
Weigh of each fish =250 grams
We have to find the value of total mass of the five lead fishing weights
Total number of fishes=5
In order to find the total mass we will use unitary method
Total mass is obtained by multiplying the total number of fishes with weight of one fish
Total mass=
Total mass of five fishes=1250 g
1 kg =1000g
Then 1250 g=
Hence, total mass of five lead fishing weights=1250 g=1.25 Kg
Answer:
the answer is A. E. coli B
Explanation:
The multiplicity of infection (MOI) refers to the ratio between the numbers of viruses used to infect <em>E. coli</em> cells and the numbers of these <em>E. coli </em>cells. Benzer carried out several experiments in order to define the gene in regard to function. Benzer observed that <em>E. coli </em>strains with point mutations could be classified into two (2) complementary classes regarding coinfection using the restrictive strain as the host. With regard to his experiments, Benzer observed that rII1 and rII2 mutants (rapid lysis mutants) are complementary when they produce progeny after coinfect E. coli K (where neither mutant can lyse the host by itself). The rII group of mutants studied by Benzer does not produce plaques on <em>E. coli</em> K strains that carry phage λ (lysogenic for λ), but they produce plaques on <em>E. coli</em> B strains. This study showed that rIIA and rIIB are different genes and/or cistrons in the rII region.
