The Constitution plays a vital role in promoting the struggle for equality among people. The Constitution is a set of fundamental principles and laws that govern a country’s political and social system. It enshrines the basic rights and freedoms of citizens, irrespective of their caste, creed, gender, religion, or social status.
The Constitution provides a framework for promoting and protecting equality among people. It lays down the foundation for a democratic and egalitarian society, where every individual has an equal opportunity to participate in the political and social affairs of the country.
Furthermore, the Constitution sets out the framework for the functioning of the government and the judiciary, which are responsible for ensuring that the principles of equality and social justice are upheld. The Constitution provides for the establishment of independent institutions like the National Commission for Scheduled Castes, the National Commission for Scheduled Tribes, and the National Commission for Women to safeguard the rights and interests of marginalized communities.
In case of any violation of the principles of equality enshrined in the Constitution, the judiciary plays a crucial role in upholding the rights of the citizens. It provides a platform for people to seek redressal for any violation of their rights and to hold the government accountable for its actions.
Therefore, the Constitution acts as a catalyst for promoting the struggle for equality among people. It provides a framework for a just and equitable society, where every citizen has equal rights and opportunities, regardless of their social status or background.

Chrysophytes are a type of plankton.
Plankton are organisms that drift or float in aquatic environments, and they can be classified as either phytoplankton (photosynthetic) or zooplankton (non-photosynthetic). Chrysophytes are a type of phytoplankton that are characterized by their yellow or brown pigmentation, which is due to the presence of carotenoids in their cells.
Chrysophytes are unicellular organisms and can be found in both freshwater and marine environments. They are important members of the food chain, as they serve as a food source for many aquatic animals, including zooplankton, fish, and crustaceans.
In summary, chrysophytes are a type of planktonic organisms, specifically phytoplankton, that are found in both freshwater and marine environments. They play an important role in the aquatic food chain as a food source for many aquatic animals.

The option that does not increase while moving down the group of the periodic table is (c) valence electrons.
As we move down a group of the periodic table, the number of shells in the atoms increases. This is because new shells are added as we move from top to bottom. Therefore, option (d) is incorrect.
The atomic radius also increases while moving down the group of the periodic table. This is because the number of shells increases, leading to an increase in the distance between the nucleus and the valence electrons. Therefore, option (a) is incorrect.
The metallic character of elements also increases while moving down the group of the periodic table. This is because the valence electrons are farther away from the nucleus, which means that they are held less tightly and can be more easily shared with other atoms in a metallic bond. Therefore, option (b) is incorrect.
However, the number of valence electrons in the outermost shell of an atom remains the same while moving down the group of the periodic table. This is because all the elements in a group have the same number of valence electrons, which is equal to the group number. Therefore, option (c) is the correct answer.

The modes referred to in the question, Ahars, Kattas, Bhundhis, and Khadins, are all related to water harvesting, which is option (c).
Water harvesting is the practice of capturing and storing rainwater for later use. This is an important technique for regions that experience water scarcity or face challenges in accessing reliable water sources. Ahars, Kattas, Bhundhis, and Khadins are all traditional techniques of water harvesting that have been used in different parts of India for centuries.
Ahars are small earthen dams that are built across seasonal streams or small rivers to impound water. Kattas are low embankments built across a stream to impound water for irrigation or domestic use. Bhundhis are small check dams constructed across a nullah (a small rivulet) to store water. Khadins are a series of check dams built across a stream or river to recharge the groundwater table.
All of these techniques are designed to capture and store rainwater and prevent it from flowing away. They help to recharge groundwater aquifers, reduce soil erosion, and support agriculture and other water-dependent activities in the region.
In conclusion, Ahars, Kattas, Bhundhis, and Khadins are all modes of water harvesting, and this technique is essential for water management in regions that face water scarcity or have unreliable water sources.

The answer is: 1) Blood capillaries and lacteal
The description given in the question is that of villi, which are small finger-like projections found in the lining of the small intestine. Villi play an important role in nutrient absorption from the digested food. The surface of the villi is covered with numerous microscopic projections called microvilli, which further increase the surface area for absorption.
Blood capillaries and lacteal are the two types of vessels that are present in the villi. Blood capillaries are small blood vessels that are responsible for the absorption of nutrients such as glucose and amino acids, which are transported to the liver and other tissues through the bloodstream. Lacteals are specialized lymphatic vessels that are responsible for the absorption of dietary fats and fat-soluble vitamins. The absorbed fats are transported by the lymphatic system and eventually enter the bloodstream.
The network of blood capillaries and lacteals in the villi is an example of the close relationship between the circulatory and digestive systems. The nutrients and other substances that are absorbed by the villi are transported to the rest of the body through the bloodstream. The lymphatic system also plays an important role in maintaining fluid balance and immunity.
Therefore, the correct answer is that the small finger-like projection in the small intestine, which produce numerous microscopic projections, are supplied with a network of blood capillaries and lacteal.

The alimentary canal is the long, muscular tube that runs from the mouth to the anus and is responsible for the digestion and absorption of food.
Among the given options, herbivores (option 1) typically have longer alimentary canals. This is because plant material is more difficult to digest than animal material, and therefore requires a longer time in the digestive system to break down and absorb nutrients. Herbivores also tend to have more complex stomachs and digestive systems with multiple compartments, such as the rumen in cows and sheep, which help to break down the tough plant material.
Carnivores (option 2) have shorter alimentary canals as their diet consists mainly of animal material, which is easier to digest and absorb. They also have simpler stomachs and digestive systems with fewer compartments as they do not need to break down tough plant material.
Insectivores (option 3) have relatively short alimentary canals as their diet consists mainly of small, easily digestible insects.
Omnivores (option 4) have intermediate-length alimentary canals as they eat both plant and animal material. Their digestive systems are more complex than carnivores but less complex than herbivores.
Therefore, the correct option is herbivores (option 1) which typically have longer alimentary canals to facilitate the digestion of plant material.

Gemmae are asexual reproductive bodies that are found in certain plant groups. These structures are responsible for vegetative propagation and allow for the production of new individuals without the need for sexual reproduction.
Among the given options, gemmae are found in mosses and liverworts.
Mosses (option 2) produce gemmae cups which contain small, multicellular gemmae. These cups are often found at the tips of the gametophyte plant and can be dispersed by raindrops, allowing the gemmae to settle and grow into new individuals.
Liverworts (option 3) also produce gemmae cups, but the gemmae are single cells or small groups of cells. The cups are often found at the base of the gametophyte plant and can be dispersed by water or wind, allowing the gemmae to grow into new individuals.
Brown algae (option 1) and red algae (option 4) do not produce gemmae. These groups of algae reproduce through the production of spores or the alternation of generations between haploid and diploid forms.
Therefore, the correct options are mosses and liverworts (options 2 and 3).

The activation of pro-carboxypeptidase into carboxypeptidase is brought about by the enzyme called Trypsin.
Pro-carboxypeptidase is the inactive form of carboxypeptidase that needs to be activated to perform its function. Trypsin is an enzyme that is responsible for the activation of pro-carboxypeptidase into carboxypeptidase. Trypsin cleaves the peptide bond located at the C-terminus of the Arginine or Lysine amino acids in the pro-carboxypeptidase molecule, thus removing the propeptide and activating the enzyme.
Enterokinase, endopeptidase, and exopeptidase are not involved in the activation of pro-carboxypeptidase into carboxypeptidase. Enterokinase is an enzyme that activates trypsinogen into trypsin. Endopeptidase is an enzyme that breaks peptide bonds within the protein molecule, whereas exopeptidase is an enzyme that cleaves peptide bonds from the end of the protein molecule.

The correct answer is A-glottis, B-trachea
The nasopharynx is a part of the pharynx or throat that lies above the soft palate and connects the nasal cavity to the oropharynx. The glottis is a part of the larynx or voice box that consists of the vocal cords and the opening between them. The trachea is a tube-like structure that connects the larynx to the bronchi of the lungs.
Therefore, option 1) A-trachea, B-lungs is incorrect because the nasopharynx does not open into the trachea, but rather the oropharynx does. Option 2) A-trachea, B-glottis is also incorrect because the nasopharynx does not open into the glottis, which is a narrow opening in the larynx that leads to the trachea. Option 3) A-glottis, B-lungs is also incorrect because the nasopharynx does not lead to the lungs.
Option 4) A-glottis, B-nasal cavity is correct because the nasopharynx opens through the glottis region of the larynx into the nasal cavity, which is the passage behind the nose and above the roof of the mouth. This allows air to pass through the nasopharynx and into the respiratory system.
