True, reddish-yellowish color on pH paper shows acidity
Answer:
Voltage-gated Ca2+ channels
Explanation:
Modulation of Ca+2 channel Epinephrine also causes an increase in cAMP that stimulates PKA that is protein kinase A, which in turn phosphorylates the voltage-gated Ca+2 channel that is the L channel. This phosphorylation results in a protein conformational change that enchances the channels activity.
Answer:
Somatic hypermutation is a process in which point mutations build up in the antibody V-regions of both the heavy and light chains.
This process occurs at rates that are about 106-fold higher than the background mutation rates observed in other genes.
It allows B cells to mutate the genes that they use to produce antibodies. This then ensures the B cells to produce antibodies that are better able to bind to bacteria, viruses and other infections.

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.
