Answer;
A. Blood
Explanation;
The main organs of the Circulatory system are the heart, the brain, the lungs. There are other key things like arteries, veins, and capillaries but they are not organs.
The major tissues in the circulatory system are the epithelial, muscle, nervous, and connective tissues.
Blood is the main connective tissue in the circulatory system, but it's a liquid connective tissue. Blood tissue is in the same family as bone and cartilage, but instead it has a liquid medium that holds it together.
Tha main components in blood are the plasma, red blood cells, white blood cells, and blood platelets.
Plasma is like the main component that makes up most of the blood. It has a light yellow color and it carries many substances including nutrients, waste, hormones and more.
Red blood cells are the reason why blood is red in color. They have a hemoglobin inside them which can help carry oxygen for the tissues and organs. In order to maximize the oxygen carrying capacity, they don't have a nucleus.
White blood cells can be divided into phagocytes and lymphocytes. Their main function is to protect us from diseases. Phahocytes and engulf and digest bacteria, while lymphocytes can produce antibodies.
Blood platelets can cause blood clotting which can stop us from bleeding forever. They're not cells, but just fragments of cells. They also don't have nucleus since they're not complete cells.
Answer:
Bacteria
Explanation:
Bacteria constitutes large group of unicellular organisms that lacks membrane bound organelles and constitute cell wall. Bacteria are used for the production of recombinant proteins.
Bacteria can be selected easily for the recombinant protein formation. The plasmid of bacteria is helpful for the integration of desired genes and the production of protein. The bacteria culture can be maintained easily in the laboratory. The different strains of bacteria with different traits can be used for the production of different recombinant proteins at low cost.
Thus, the correct answer is option (1).
West Coast water temperatures are much lower than those along the East Coast. ... This means Atlantic waters travel to the U.S. East Coast from the south and are relatively warm compared with West Coast Pacific waters that arrive from the north out of the chilly Gulf of Alaska.
The air above the cold Benguela current and upwelling region along the west coast is relatively dry and cold, contributing to the dry climate of the west coast. Moist air from the warm Indian Ocean and Agulhas Current is frequently transported into eastern South Africa by easterly winds.
