Answer : 1. "epithelium"
Explanation :
The tissue that forms glands is:
(A) Epithelium
Explanation:
Epithelial tissue is responsible for the formation of glands. Glands are structures that produce and secrete substances such as hormones or enzymes. Epithelial cells can be organized to form glandular tissues, and glands can be classified into two main types: exocrine glands and endocrine glands. Exocrine glands release their secretions through ducts, while endocrine glands release hormones directly into the bloodstream. Epithelial tissue plays a crucial role in the formation and function of both types of glands.

Answer : 1. "Nitrogen"
Explanation :
The term "overdose" in the context of essential elements for plants suggests an excess or imbalance of nutrients, which can have negative effects on plant health. Among the options given:
(A) Nitrogen
Explanation: While all nutrients are essential for plant growth, an overdose or excessive application of nitrogen (option A) can lead to problems such as nutrient imbalance, environmental pollution, and increased susceptibility to certain diseases. Excessive nitrogen can cause rapid vegetative growth, but it may negatively impact other aspects of plant health, such as root development, flowering, and overall resilience.
Balanced nutrient management is crucial for optimal plant growth, and it's important to consider the specific requirements of each plant species and the soil conditions to avoid nutrient imbalances and potential negative effects on plant health.

They communicate with each other, work together for the common good of the colony, and have a complex social structure. In contrast, mosquitoes, bur (assuming it refers to burrowing animals), and domestic flies are not typically considered social animals in the same way as bees. Bees, especially honeybees, are well-known for their intricate social organization and cooperation within the colony.

Answer : 3. "Defense"
Explanation :
The main function of epithelial tissue is:
(C) Defense
Explanation:
Epithelial tissue serves as a protective covering for the body and its organs. It acts as a barrier that helps prevent the entry of pathogens and other harmful substances. Epithelial cells are tightly packed and form continuous sheets, providing a protective layer on the body surfaces, both internal and external. This protective function is essential for defending the body against infections and maintaining its integrity. Therefore, option (C) Defense is the correct answer.

Answer : 1. "Thrombin "
Explanation :
The substance that causes the clotting of blood is:
(A) Thrombin
Thrombin is an enzyme that plays a crucial role in the blood clotting process. It is responsible for converting fibrinogen, a soluble plasma protein, into insoluble fibrin threads. These fibrin threads form a mesh that helps in the clotting of blood, particularly at the site of injury or wound. Therefore, option (A) Thrombin is the correct answer.
