Common Diseases In Human Beings

The correct answer is (C): Cannabis sativa
Skeletal Structure of Cannabinoid Molecule:
The "skeletal structure" refers to the basic arrangement of atoms in a molecule, which provides the underlying framework for the molecule's chemical composition. In the context of the statement, it is indicating the specific arrangement of atoms in the cannabinoid molecule.
Source of the Cannabinoid Molecule:
The source of the cannabinoid molecule is specified as "Cannabis sativa." Cannabis sativa is a plant species known for containing various compounds called cannabinoids, which have significant biological effects on the human body when consumed
Connection Between the Skeletal Structure and Source:
The statement implies that the cannabinoid molecule's skeletal structure is characteristic of those found in Cannabis sativa. In other words, the unique arrangement of atoms in the cannabinoid molecule is a distinguishing feature that is commonly present in compounds derived from Cannabis sativa.
Correct Answer:
Given the context, the correct answer to the question "Which is obtained from Cannabis sativa" is indeed "Cannabis sativa." This means that the specific cannabinoid molecule being referred to in the statement is sourced from the Cannabis sativa plant."

The correct answer for the statement regarding IgE is (C) : Giving immune response to allergens
IgE, or Immunoglobulin E, is a type of antibody that plays a critical role in the immune system's response to allergens. When the body is exposed to certain allergens (such as pollen, pet dander, or certain foods), it triggers an immune response. During this process, B cells, a type of white blood cell, encounter the allergens and produce specific antibodies, including IgE. IgE antibodies bind to the allergens and attach to the surface of mast cells, which are a type of immune cell found in tissues throughout the body. When the same allergen is encountered again, it binds to the IgE antibodies attached to the mast cells. This triggers the release of histamine and other chemicals from the mast cells, causing the symptoms of an allergic reaction, such as sneezing, itching, hives, or even more severe reactions like anaphylaxis. The other options in the statement are incorrect: - Inhibits the secretion of histamine and serotonin from mast cells: This is not accurate. IgE actually promotes the release of histamine and other mediators from mast cells, as explained in the explanation above. - Does not stimulate B cells: This is also incorrect. IgE is produced by B cells and plays a significant role in stimulating B cells during the immune response to allergens. - This antibody is received from the mother to the fetus through the placenta during pregnancy: This statement is incorrect as well. While IgG antibodies are the main type of antibodies transferred from the mother to the fetus through the placenta, IgE is not typically transferred in significant amounts during pregnancy. IgE levels in a fetus are generally low and increase after birth as the immune system develops and the child is exposed to various allergens.

One of the key symptoms of pneumonia is the lack of sufficient oxygen in the blood, which can cause the lips and fingernails to appear gray or blue, a condition known as cyanosis. This occurs when the lungs are unable to effectively oxygenate the blood due to infection or inflammation. Cyanosis is a significant indicator for doctors to suspect pneumonia.

Cirrhosis is a progressive liver disease where healthy liver tissue is replaced by scar tissue, impairing the liver's ability to function. One of the leading causes of cirrhosis is excessive alcohol consumption over an extended period. Chronic alcohol abuse can lead to liver damage, resulting in cirrhosis.
