A new DNA strand elongate only in the 5' to 3' direction during DNA replication because the "polarity of the DNA molecule prevents addition of nucleotides at the 3' end" .
DNA replication occurs in the 5' to 3' direction. DNA polymerase can only add nucleotides to the 3' OH group of the growing DNA strand, this is why DNA replication occurs only in the 5' to 3' direction.
DNA polymerase can only add to the 3' end, so the 5' end of the primer remains unaltered. Consequently, synthesis proceeds immediately only along the so-called leading strand.
Hence, the correct answer will be option (B)

Answer:
All of these examples show evidence for evolution because they show change over time and descent from a common ancestor
Answer:
a sense organ
Explanation:
this is because sense organs are part of nervous system
" a boat sails across the ocean" possess Kinetic energy. hence option d is correct.
<h3>
What is Kinetic energy?</h3>
- Chemical energy, thermal energy, electromagnetic radiation, gravitational energy, electric energy, elastic energy, nuclear energy, and rest energy are only a few of the many different types of energy that exist. Potential energy and kinetic energy are the two basic categories that can be used to group them.
- An object's kinetic energy is what drives its motion. Kinetic energy can be converted into other types of energy and transported between objects.
- The energy an object has as a result of motion is known as kinetic energy in physics. It is described as the effort required to move a mass-determined body from rest to the indicated velocity. The body holds onto the kinetic energy it acquired during its acceleration until its speed changes.

The correct answer is: ensure that all tubes are attached to collection devices
An adequately functioning nasogastric (NG) tube should prevent nausea and vomiting because stomach contents are continuously being removed. Using the NG after abdominal surgery is a routine postoperative procedure until gastrointestinal tract starts to function properly. The patency of the tube should be checked together with the amount and character of gastric drainage.
