Vacuoles are essentially sacs surrounded by a membrane. They are used by cells as temporary storage sites. They often store food, enzymes, and other materials needed by the cell, and some vacuoles store waste products.
Plutchik suggested we have 8 primary emotions that combine to form secondary emotions. Putchik identified ten postulates on which his evolutionary theory of emotions is based. Plutchik's wheel of emotion illustrates the relationships between his primary emotions and other related emotions. The eight basic emotions are joy, trust, fear, surprise, sadness, anticipation, anger, and disgust.
Answer:
The correct answer would be - 9 hours.
Explanation:
The half life of a drug is the time that is required to decrease or reduced to one half of the its original achieved level or the highest amount previously taken. The half life of drug is also known as the time a drug take to complete its action.
At a dose of 500 mg the Fluoxitine drug would be 250 mg in 3 hour as it is given that half life of this drug is 3 hours, 125 mg in 6 hours, and in the end 62.5 mg in 9 hours.
Thus, the correct answer is : 9 hours.
Answer:
Evolution
Explanation:
Evolution is a gradual change in a population that occurs overtime in a species.
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.
