Statement D. Is not true.
Water is a polar molecule because its opposite ends have opposite electric charges.
The amount of water reabsorbed during the formation of urine can be changed by hormones, enabling the creation of either concentrated or diluted urine. The duct serves this purpose.
In heating, ventilation, and air conditioning (HVAC), air is delivered and removed by ducts, which are conduits or passageways. Examples of the necessary airflows include supply air, return air, and exhaust air. As part of the supply air, ducts frequently deliver ventilation air as well. As a result, air ducts are one way to guarantee both thermal comfort and adequate interior air quality. The brain releases a substance called antidiuretic hormone (ADH), which makes the kidneys release less water and reduces the volume of urine generated. The body makes less pee when its ADH level is high. A low

Answer:
True.
Explanation:
Antigen may be defined as the chemical that has the ability to evoke the and immune response and can harm the living organisms. The specific antibody are produced against the immune response.
The antigens has evolved different mechanisms to prevent themselves from them the immune system of the host. The antigenic shift is the most common change that might occur in viruses that helps the antigen to protect itself by changing its genetic material. No anti viral drugs are available for the viruses.
Thus, the answer is true.
Answer:
By doing more research.
Explanation:
The cell theory change with the passage of time by doing more research about the cell. The final modification of the cell theory done by Rudolf Virchow in 1855 on the basis of his new research and findings about the cells. With the passage of time, modification occurs in microscope which enable the scientists to find different parts, organelles and features of cell on the basis of which scientists modify cell theory with the passage of time.
