HP TET TGT Medical Mock Test - 7 - HP TET MCQ

The sounds th, ph, ch are phonemes. The phoneme is the unit of sound.  A phoneme combines with other phonemes to give rise to meaningful words. Phonemes distinguish one word from another. These are established by the use of minimal pairs, such as pat vs bat or tap vs tab.
Hence, the correct answer is, 'Phonemes.'

In order to avoid gender stereotyping in class, a teacher should try to put both boys and girls on non-traditional roles. A teacher should take care of each child irrespective of their gender. He/she should ensure the students' maximum potential. Everyone has the right to education. A teacher should ensure that his/her students derive maximum benefit from education.
Hence, the correct answer is, 'Try to put both boys and girls in non-traditional roles.'

The teachers should allow students to make some decisions about what to learn and how to learn. It helps to increase their thinking ability in critical analysis. Also, it points out their strengths and weaknesses and the students can learn well through the diagnosis of the learning gap.
Hence, the correct answer is, 'Allowing students to take some decisions about what to learn and how to learn'.

Motivation is the process of learning that defines a reason for a person to do something or the desire a person has to do something. It creates interest in learning among young learners. If learners are motivated they will perform their work efficiently and effectively and if they are not motivated to do something then it will affect their performance.
Hence, the correct answer is, 'Creates interests for learning among young learners.'

Jean Piaget has proposed four stages in his cognitive development theory. The First stage is the sensorimotor stage which occurs from birth to 2 years, second is the pre-operational stage which occurs from 2 to 7 years of age, the third is the concrete operational stage which occurs from 7 to 11 years of age. This is the stage when a child begins to think logically about objects and events. Last is the formal operational stage which occurs above 12 years of age.
Hence, the correct answer is, 'Concrete operational stage.'

The 'insight theory of learning' was proposed by Wolfgang Kohler. During the time when he was studying the behaviour of apes, he has designed some simple experiments that lead to the development of the cognitive theories of learning which he referred to as insight learning.
Insight learning is the form of cognitive learning in which animals are used by Kohler to get the results. It occurs in human learning when people recognize relationships that can help them in solving problems.
Hence, the correct answer is, ''Gestalt theorists.'

Molecular mass of the gas = Molecular mass of N₂ = 28 g 

Molecular formula mass = n X (Empirical formula mass) 

Empirical formula mass of the gas = 12 + 2 = 14 g 

Therefore, n = 28/14 = 2 

Hence the molecular formula is (CH₂)₂ or C₂H₄. 

The correct answer is option D
Electrical resistivity (also called specific electrical resistance or volume resistivity) and its inverse, electrical conductivity, is a fundamental property of a material that quantifies how strongly it resists or conducts electric current. ... The SI unit of electrical resistivity is the ohm-meter (Ω⋅m).
 

1 mole = 6.023 × 10²³ atoms / molecules = X
1 mole = Molar volume =22.4 L at NTP = Y
1 mole = Gram atomic mass or gram molecular mass = Z
Hence, option B is correct.

• Cytological structure of all the above options revealed that they lack flagella. 
• Red alga is eukaryotic without flagella, centrioles, with phycobiliproteins and chloroplast lacking external endoplasmic reticulum and unstacked thyllakoid. 
• Cyanobacteria do not have organs for movement such as flagella, but some filamentous BGA exhibit gliding movement due to slime secretion along with contractile waves in the cells.
• In case of higher seed plants (Spermatophyta) like gymnosperm and angiosperm, flagella are absent since, presence of pollen grain eliminated use of water for fertilization. 

While bryophytes are primarily terrestrial plants, they require a moist environment for the process of fertilization. Their sperm are flagellated and need water to swim to the egg for fertilization to occur, similar to how amphibians need a water environment for reproduction. However, this does not mean they live in water; rather, they need water for a crucial part of their life cycle.

In the C4 pathway, initial carbon fixation takes place in mesophyll cells and the Calvin cycle takes place in bundle-sheath cells. PEP carboxylase attaches an incoming carbon dioxide molecul to the three-carbon molecule PEP, producing oxaloacetate (a four-carbon molecule).

Each NADH molecule theoretically yields 3 ATP molecules during chemiosmosis. However, in some tissues, NADH requires more energy to cross the mitochondrial membrane and some of its potential is lost.

1. Krebs cycle is also known as the citric acid cycle because this reaction starts with the six-carbon compound which is citric acid. It occurs in the mitochondrial matrix.
2. Krebs cycle is a closed-loop cycle. And each loop of the cycle generates a molecule of ATP. This cycle consists of eight steps which include redox, dehydration, hydration, and decarboxylation reactions. It is an aerobic pathway because NADH is produced and the electrons released are used up in the next cycle which uses oxygen.
3. The process of the cycle starts with the condensation of acetyl- CoA with oxaloacetate.
4. This reaction is controlled by the amount of ATP present.
5. If the ATP level increases then the rate of the reaction decreases and vice versa. After glycolysis, the pyruvate is then converted into acetyl CoA which enters the citric acid cycle.
6. The Krebs cycle is the pathway that all organisms use to generate energy. The intermediate compound that links pyruvate to the Krebs cycle is Acetyl CoA.
7. So, the answer is option (B) ‘the intermediate compound which links glycolysis with the Krebs cycle is malic acid’.

Photosynthetically Active Radiation (PAR) of solar radiation is a visible region. It consists of radiations having wavelengths between 400 to 700 nm.

Quantum yield is the number of Oxygen molecules released per photon or quantum of light. During light reaction of photosynthesis oxygen molecules are release during photolysis.

Photophosphorylation is the conversion of ADP to ATP using the energy of sunlight by activation of PSII. This involves the splitting of the water molecule in oxygen and hydrogen protons (H⁺), a process known as photolysis.

• Phylum is one of the major taxonomic ranks, and it represents a high-level grouping of organisms that share certain fundamental characteristics.
• Within a phylum, organisms are further divided into classes, which are more specific and share even more closely related characteristics.

Correct answer is B.
NCERT Reference: Topic - Taxonomy from chapter "The Living world" of NCERT.

A nucleoside is a compound which contains nitrogen bases i.e., purines and pyrimidines attached with the sugar molecule. When nucleoside attached with phosphate ion is called as a nucleotide. Thus, the correct answer is option A.

Carrying capacity of a habitat is the maximum number of individual that can survive in given habit. There is a limitation of food, water and space in a habitat so only limited numbers of individual survive.

The centrosome is present in the cytoplasm of the animal cell. It is made up of two centrioles and helps to organize microtubules and pull chromatids apart during cell division. So, the correct answer is option C.

Crossover is the exchange of genetic material that occurs between two homologous chromosomes (a set of one maternal and one paternal chromosome that pair up with each other inside a cell during meiosis) non-sister chromatids that results in recombinant chromosomes during sexual reproduction.

Endosperm cells are triploid as they are formed by triple fission of two polar nuclei and one male gamete. So, haploid cell will contain 8 chromosomes only. Root cells are diploid. Hence root cell will contain 16 chromosomes.

Interactions between different species living within a particular area may be useful as in case of mutualism, fatal as in case of parasitism or neutralin which no one is harmed.

The diatom shells piling up at the bottom of oceans over millions of years formed deposits called diatomaceous earth.These deposits may be thousand metres thick with as many as five million diatom shells in each cubic centimetre. This diatomaceous earth is used in many small and large scale industries.

F₁ particles are also known as oxysomes or elementary particles or F₁-F₀ particles. These particles are present in matrix side of mitochondrial inner membrane. In mitochondria, F₁ particles function in synthesizes ATP from ADP + Pi. F₁ particles comprise about 15% of the total inner membrane protein.

The European traveler "Moorcraft" visited Himachal Pradesh during the period 1820-1822 AD.

He was a veterinary surgeon who, after maintaining a veterinary practice for a time in London, was engaged in 1807 by the East India Company to manage its breeding of horses. He arrived in India in 1808 and took charge of the company’s stud operations at Pusa, Bengal.

In 1811 and 1812 he undertook journeys to the northwest in search of larger and better stud horses than he was able to find in India. In May 1819 Moorcroft received permission from the East India Company to travel to Bukhara (in present-day Uzbekistan).

Increase in carbon dioxide concentration in atmosphere takes place due to green house effect. The greenhouse effect is a warming of Earth’s surface and troposphere (the lowest layer of the atmosphere). It is caused by the presence of water vapor, carbon dioxide, methane, and certain other gases in the air.

Apart from India, Pakistan, and Sri Lanka, Nepal country has Rupee as its currency.
