Host A and B are communicating over a TCP connection, and Host B has already received from A all bytes up through byte 100. Suppose Host A then sends two segments to Host B back-to-back. The first and second segments contain 200 and 300 bytes of data, respectively. In the first segment, the sequence number is 101, the source port number is 2000, and the destination port number is 3000. Host B sends an acknowledgment whenever it receives a segment from Host A. a. If the first segment arrives before the second segment, in the acknowledgment of the first arriving segment, what are the acknowledgment number, the source port number, and the destination port number? b. If the second segment arrives before the first segment, in the acknowledgment of the first arriving segment, what is the acknowledgment number?

In normal cells, when insulin binds to its receptors on the target cell, glucose transporters get activated which then allow glucose to get into the cell from the blood vessels. Insulin is a protein hormone, so its receptor would be ___________ . Glucose transporter is a/an ___________. If insulin receptor is absent, glucose will __________to enter the cell. Insulin binds to the normal insulin receptor but the glucose transporter is nonfunctional, in that case, glucose will __________ into the cell.
