Answer:
The 5' and 3' polarity restriction
Explanation:
Discontinuous replication is when synthesis of new DNA molecule takes place as a series of short fragments that will subsequently be joined together.
These fragments are called the Okazaki fragments.
DNA synthesis takes place from 3' to 5' end. However due to 5' and 3' polarity. The replication has to be discontinuous due to the synthesis happening backwards and okazaki fragments being formed.
The bark of a tree is impervious to gases and water because bark cells are dead cells of the epidermis and compactly arranged without intercellular spaces. They contain a chemical called suberin in their walls that make them impervious to gases and water and it doesn't allow gases or water into the tree as bark cells are in the bark outer most layer of the tree.
Sample A most likely came from the left ventricle, as this is the portion of the heart that receives freshly oxygenated blood to be pumped to different parts of the body. Oxygenated blood is blood that has had oxygen bounded to it by hemoglobin (a pigment made of iron found in red blood cells). The oxidation of this blood by the iron in the hemoglobin gives it the RBC bright red look. This blood containing the bright RBCs in transported to the left ventricle from the lung, after which it is spread throughout the body. Hence, in normal conditions of the heart, the Sample A most likely came from the left ventricle.
A which country had the most cases of tbt
It isn’t sea anemone nor the beetle because they belong to the Animalia Kingdom so the answer would be AMOEBA and SEAWEED
