Answer: Memory cells.
Explanation:
Vaccines are effective because they lead to the production of memory cells which remembers the experience when the body got an exposure to the antigen for the first time.
When the antigen get exposed to the body, B cells of the body are activated. They further get divided into two parts, one part forms plasma cells and the other part forms memory cells.
The plasma cells secrete antibodies in the blood to fight disease and other part gets stored in the lymph until it is exposed for the second to antigen which will convert them into plasma cells.
The reserved cells are known as memory cells.
Answer:
The answer is: nasal conchae
Explanation:
The nasal conchae, also known as turbinates, are the elongated curled shelf of bone that protrudes into the nasal cavity. It is present on the lateral surface of the nasal cavity.
It is responsible for the directing the airflow direction, heating, filtering and humidification, of the air inhaled through the nose.
Answer:
Inflammation is a response triggered by damage to living tissues. The inflammatory response is a defense mechanism that evolved in higher organisms to protect them from infection and injury.

b) None of these
c) All of these
d) Renal tubule
e) Glomerulus
Answer: Option C
Explanation:
The nephron is the microscopic structure found in the kidney. It is the structural and functional unit of kidney.
It is composed of renal tubule, glomerulus and Bowman's capsule. The renal corpuscles consists of a tuft of capillaries which is known as glomerulus.
Bowman's Capsule can be defined as a sac like structure that lies at the starting of the tubular part of a nephron in a kidney. It performs the first step of filtration of blood that reaches the kidney.
Hence, the correct answer is all of these.
The nephron, the functional unit of the kidney, is comprised of the Bowman's capsule, the Renal tubule, and the Glomerulus. The Glomerulus initiates the filtration process, and the filtered blood enters the Bowman's capsule. The renal tubule takes part in reabsorption and secretion.
The functional unit of the kidney, known as the nephron, is comprised of different elements, each playing its unique role in the process of ultrafiltration and urine formation. These elements include the Bowman's capsule, the Renal tubule, and the Glomerulus. Therefore, the correct answer to this question is c) All of these.
The Glomerulus is a network of tiny blood vessels where the filtration of blood plasma begins. This filtered blood then enters the Bowman's capsule, a cup-like sac that surrounds the Glomerulus and collects the filtrate. The renal tubule, on the other hand, is a tube where necessary substances are reabsorbed back into the blood, and unwanted substances are secreted into the urine.

b. False
Answer:
The answer to the question: The membrane potential seeks the equilibrium potential of the ion whose permeability is dominant, would be, True.
Explanation:
When a cell needs to prepare to activate itself, or start what is known as an action potential, there needs to be a change in the polarity that is constant over the cell membrance. Usually, this polarity tends to be primarily negative on the inside thanks to the anions, and positive on the extracellular side, thanks to the concentration, particularly of sodium ions. In general, and without stimulus, this resting membrane will not activate or generate anything. However, when the cell activates, several channels, both leakage and gated, will activate to allow the two most important ions, sodium and potassium, to leak in and out of the cell to generate an electrical gradient. In order to restore this, and return to resting, the cell´s membrane must restore its potential, and thus, it will activate the channels of the dominant ion, to restore the balance. In fact, normally, there are leakage potassium channels in the cell membrane that allow potassium to leak out of the cell, helping to maintain the negativity of the cytoplasm, and the stability.
Recent research has shown that using over-the-counter drugs containing ibuprofen can potentially reduce the risk of developing certain types of cancer.
Specifically, studies have suggested that regular use of non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen may lower the risk of developing colon, breast, and prostate cancers. This is because NSAIDs work by blocking an enzyme called cyclooxygenase (COX), which is involved in inflammation and also plays a role in the development of certain cancers.
By inhibiting COX, NSAIDs may help prevent the growth and spread of cancer cells. However, it is important to note that regular use of NSAIDs can also have side effects and risks, such as gastrointestinal bleeding and kidney damage.
Therefore, it is important for individuals to consult with their healthcare provider before using NSAIDs for long periods of time or on a regular basis. Therefore ibuprofen can reduce the risk of the disease cancer.
