Correct answer is (D. Once created in bone marrow, they circulate for our lifetime)
I do believe the answer is B
<span>The answers are the substances found in the
simple compounds of Hydrogen</span><span>, ammonia, methane and water and when they will undergo melting or boiling, there are weak
'intermolecular forces' that break them which is the reason why it is not a strong

Answer:
A. They center on the motives of wrongdoers as well as on the amount of damage done when assigning blame.
Explanation:
The Concrete Operational Stage, according to Piaget, refers to a stage that begins around age 7 and ends around the ages of 11 or 13.
During this stage, children are now capable of thinking in a more logical manner and their moral judgement has become subjective as <u>they now center on the motives of wrongdoers as well as on the amount of damage done when assigning blame</u>. For instance, they are able to judge another child according to the amount of damage she/he has done and whether it was done in purpose or accidentally.
They can also center on two dimensions of a problem at once and have thoughts that involve tangible objects instead of abstract ideas.
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.
