Answer:
Primary active transport
Explanation:
Active transport may be defined as the movement of particles against their concentration gradient with the help of an energy source like ATP. Two main types of active transport are secondary active transport and primary active transport.
Primary active transport includes the sodium potassium pump because it directly uses the stored chemical energy in the form of ATP. Three sodium moves out of the cell and two potassium moves inside the cell with the help of ATP.
Thus, the correct answer is option (a).
Answer: 24 months
Explanation:
According to John Bowlby's Attachment Theory, infants go through 4 stages of attachment which are the Pre-attachment phase, Attachment-in-making phase, Clear-cut attachment phase, and Formations of reciprocal relationships phase.
Anna is in the <em>Formations of reciprocal relationships</em> phase which kicks in at around 24 months. At this stage, infants begin to take into account the feelings of others before acting. They are able to understand what refusal means and so can try to hide things they think are wrong so as not to get into trouble.
