HP TET TGT Medical Mock Test - 9 - HP TET MCQ

All differences between individuals may be interpreted by the facts of heredity or nature, environment or nurture, and training. Individuals have various endowments, abilities and capacities, provided by heredity which decide the path of progress and development of an individual. Environment also plays a key role in individual differences. No person from birth to death get the same environment. Both nature (heredity) and nurture (environment) are strong contenders in order to distinguish one individual from another.

Girl students are as good at Mathematics as boys of their age. Abilities and skills are not limited to a particular gender. Capabilities in Mathematics is nothing to do with gender. Both are equally capable. Girls are not less than boys in any sector, field.
Hence, this is the correct answer.

• Gender inequality is the social phenomenon in which men and women are not treated equally.
• The treatment may arise from distinctions regarding biology, psychology, or cultural norms prevalent in the society.
• Gender inequality is experienced differently across different cultures. 
• In practice, it means discrimination against women in various aspects such as access to education, job or even free mobility. 

Therefore, the above example is of gender inequality. 

The teacher should focus on every child so that no one feels leftover, scolding weak students will discourage them, the teachers to support them so that they get motivation from their support. When children have positive support then they can work better than before and when we applause for someone and appraise for something then that children will boost up their morale.
Hence, the correct answer is "Applause and tell them to do work".

Classroom management is the responsibility of the class teacher as she is the one who manages children, she knows how to handle children, she knows how to control emotions, how to teach them, what is right or wrong for the children.
Hence, the correct answer is "Class-teacher".

Social interactions can help learners organize their thoughts, reflect on their understanding, and find gaps in their reasoning. Social interaction can also help increase participation, as it provides students with an environment where they can participate in learning activities and discussions. So, Learning is facilitated by social actions 

For reduction of 1 mol of Al³⁺ to Al, 3 mol of electrons are required so total charge will be 3F.

OF₂ Fluorine is most electronegative atom with oxidation number = - 1
x - 2 = 0
x = + 2
H₂O₂   2 + 2x = 0 ⇒ x = - 1 

The chemical formula for baking soda is NaHCO₃, which stands for sodium bicarbonate. Baking soda is commonly used in various applications such as in cooking, as an antacid, and as a water softener due to its alkaline properties.

H = T + V

Stronger oxidizing agent means more easily it undergoes reduction and thus have greater standard reduction potential.
Remember, Li is the strongest reducing agent and F is the strongest oxidizing agent

In the equation both side of reaction moles of atoms is conserved ie, both reactant and product contain 4H and 2O but there is 3 (2+1) moles of reactant molecules turns into 2 moles of product molecules. 

One molecule of sugar (C₁₂H₂₂O₁₁) = 45 atoms
Number of moles of sugar = 1000/342 = 2.92
Number of molecules = 2.92 x 6.023 x 10²³
= 17.60 x 10²³
molecules Number of atoms = 45 x 17.60 x 10²³ 
= 7.92 x 10²⁵ atoms

Krebs' cycle produces 2 GTP (or 2 ATP) through substrate level phosphorylation. Six molecules of NADH₂ and 2 molecules of FADH₂ for every two molecules of Acetyl CoA oxidised by it.

There is clear division of labour within the chloroplast. the membrane system is responsible for the light reaction ( trapping light energy and synthesis of ATP and NADPH) while dark reaction i.e., enzymatic reactions for the reduction of carbon dioxide into sugar using ATP and NADPH take place in the stroma.

• In ETS cytochromes (electron acceptors), ATP synthesis are arranged in series of Cyt b - c₁ - c - a - a₃.
• Cytochromes are the electron carriers in different electron transport complexes in the membrane of the mitochondria which help in the formation of ATP by the process of oxidative phosphorylation.
• The sequence of the movement of the electrons include cytochromes b, cytochrome c, cytochrome a, and cytochrome a₃.

• Red algae secretes and deposits calcium carbonate over their wall to contribute in producing coral reefs in sea water. They are called coralline algae e.g., Corallina. 

Hence, the correct option is C.

• Kelps are marine algae of class phaeophyceae.
• The body of kelp may be upto 100 metre long.
• They vary in colour from olive green to various shades of brown depending upon xanthophyll pigments.

Hence, the correct option is B.
NCERT Reference: Topic “Phaeophyceae” of chapter Plant Kingdom.

The evolution of oxygen during the light-dependent steps in photosynthesis (Hill reaction) was proposed and proven by British biochemist Robin Hill. He demonstrated that isolated chloroplasts would make oxygen (O2) but not fix carbon dioxide (CO2).

Hill's reaction or light reaction takes place in thylakoids and the end products of this reaction are ATP and NADPH2. Blackman's reactions or dark reactions take place in the stroma of the chloroplast. In dark reactions, sugars are synthesized from carbon dioxide by using ATP and NADPH2, which are end products of Hill's reaction.

Hence, the correct answer is Option D.

During reproduction of fungus through fragmentation, Mycelium separates into pieces which in turn grow to form new mycelium. Fragmentation is one of the most common modes of asexual reproduction in Basidiomycetes.

The mammary glands of the female undergo differentiation during pregnancy and start producing milk towards the end of pregnancy by the process called lactation.

Lactiferous glands present inside the mammary gland produce milk due to the release of the hormone oxytocin from pituitary glands.

Hence, the correct option is D.

NCERT Reference: topic “PARTURITION AND LACTATION” of chapter: Human Reproduction.

In a food chain, number of organisms reduce from producer to carnivores at each trophic levels. So, the number of carnivores will be less than the prouder which is less than 10 million.

Polyspermy

- Polyspermy occurs when more than one sperm cell successfully fertilizes an egg.
- This can lead to abnormalities in the resulting embryo, as multiple sets of chromosomes from different sperm can cause genetic complications.
- In most cases, polyspermy is prevented by the egg's zona pellucida, which only allows one sperm to penetrate and fertilize the egg.
- If polyspermy does occur, it can result in failed fertilization or the development of an embryo with too many chromosomes.
- Polyspermy is usually considered a detrimental outcome in fertilization, as it can lead to miscarriage or developmental issues in the resulting offspring.

During 1931, under Yadunandan Sharma leadership, did a strong Kisan Sabha Movement develop in the Gaya District of Bihar.

₹86,000 crore  budget estimate for the Mahatma Gandhi National Rural Employment Guarantee Program (MGNREGA) in the fiscal year 2024-2025.

Ecosystem: All organisms such as plants, animals, microorganisms and human beings as well as the physical surroundings interact with each other and maintain a balance in nature.

• All the interacting organisms in an area together with the non-living constituents of the environment form an ecosystem.
• The term ecosystem was coined by Tansley.

Persistent organic pollutants (POPs) are persistent, mainly lipid-soluble chemicals which bioaccumulate in fatty tissues and are biomagnified up the food web, and pose a risk to human health and the environment.

Dichlorodiphenyltrichloroethane, commonly known as DDT, is a colorless, tasteless, and almost odorless crystalline chemical compound, an organochlorine.

Originally developed as an insecticide, it became infamous for its environmental impacts.

So, DDT is a Persistent Organic Pollutant (POP).
