Question
1. Receptor -based endocytosis depend on the surface receptor to enter in the cell. Hence it is a true statement.
29. As in this cell, sucrose would move from low concentration to high concentration, means against it's concentration gradient. Therefore it will use active transport which requires ATP to get transport. Hence option c is correct.
3. In the phospholipid layer, head are hydrophilic and tails are hydrophobic. Hence option a is correct.
4. RNA primer is required to initiate the DNA replication because DNA polymerase could not start with new strand. Hence option c is correct.
33. The central dogma define the flow of genetic information from DNA to protein via mRNA. Hence option c is correct.
