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

Evaluation is a systematic process of collecting and analyzing data in order to determine whether, and to what degree, objectives have been, or are being, achieved. It leads to decision making. 

Key Points

Specifically, there are three types of evaluation used in the classroom. These are summative evaluation, formative evaluation and diagnostic evaluation. 

• Formative Evaluation-
  • It is done during the course of instruction with a view to improving students' learning.
  • The purpose of this evaluation is to provide feedback regarding the students' progress, by finding out the learning gaps and the weak points. The teacher can then organize remedial programmes for them. 
  • It also provides the teacher feedback regarding the efficiency of the teaching methods, so that the teaching can be improved.
• Summative Evaluation-
  • It comes at the end of the term, course or programme of teaching. It involves formal testing of a pupil's achievement.
  • Annual examinations and half-yearly examinations in schools, public examinations are the example of such evaluation.
• Diagnostic Evaluation- 
  • The purpose of the diagnostic evaluation is to find out the underlying cause of weaknesses in a student's learning, but it is also needed even prior to instruction in order to place the student properly by looking at a higher level of achievement. Thus, diagnostic evaluation provides a starting point to carry out the instruction. 

Thus from above-mentioned points, it is clear that formative Evaluation provides the teacher feedback regarding the efficiency of the teaching methods so that the teaching can be improved. 

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.'

A student of any class having a problem of  'visual deficiency' should be treated normally within the classroom and provided support through audio CDs. Children suffering from 'visual deficiency are unable to see, in that case, they should be provided adequate support through audio lectures so that they also gain the same level of understanding as other students.
Hence, the correct answer is, 'Treated normally in the classroom and provided support through audio CDs.'

A teacher should possess some qualities to teach at the primary level such as she should have the patience to deal with all sorts of questions arising in the minds of the students. Students at the primary level ask very silly questions she should not get frustrated with them and reply in a very calm manner. Apart from this, a teacher should also have a quality of perseverance she should stick to her plans and not lose hopes even if she is facing many difficulties in achieving them.
Hence, the correct answer is, 'Patience and Perseverance.'

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. 

A + B → AB divide given moles of each reactant by their stoichiometric coefficient , the one with least ratio is limit reagents divide with their co efficient A=2/1 =2 B=3/1 =3. So A is the limiting reagent.

In 1913, Henry Moseley showed that the atomic number of an element is a more fundamental property than its atomic mass.

2NaN₃ → 2Na + 3N₂
As above reaction is already balanced we can write:
2 moles of NaN₃ ≡ 3 moles of N₂ 
So, moles of NaN₃ ≡ 8.75 moles of N₂
8.75 x 2/3 = 5.83 moles of NaN₃. 

Arsenic is a chemical element with the symbol As and atomic number 33.
Arsenic occurs in many minerals, usually in combination with sulfur and metals, but also as a pure elemental crystal.
Arsenic is a metalloid. It has various allotropes, but only the gray form, which has a metallic appearance, is important to the industry.

Let atomic weight of element X is x and that of element Y is y.

Correct Answer : b

Explanation : (a) It represents R2 vs r for 1s

(b) It represents R2 vs r for2s

(c) It represents R2 vs r for 2p

• The strongest oxidizing agent is one having more positive or less negative reduction potential.
• For the strongest oxidizing agent, the oxidizing potential should be the least.

Here, the oxidizing potential of Fe⁺² is less than that of [Fe(CN)₆​]⁴⁻. Therefore, Fe⁺² is a stronger oxidizing agent than [Fe(CN)₆​]⁴⁻.

• Also, the stronger oxidizing agent should easily reduce itself.

Here, Fe⁺³ is easily reduced than Fe⁺². Therefore, among all the four, Fe⁺³ is the stronger oxidizing agent.

Calcium carbonate reacts with sulphuric acid to form calcium sulphate and carbon dioxide which turns lime water milky.

CaCO₃ + H₂SO₄ → CaSO₄ + CO₂ + H₂O

Moles of CO =8 moles Moles of Fe₂O₃= 2.5 moles.

3 moles of CO is needed for 1 mole of Fe₂O₃ so 8 moles of CO will require 2.66 mole of Fe₂O₃ so Fe₂O₃ is limiting reagent.

1 mole of Fe₂O₃ produce 2 mole of Fe so 2.5 mole of Fe₂O₃will produce 5 mole of Fe = 280g of Fe.

Also 1 mole of Fe₂O₃ also produce 3 mole of CO₂ so 2.5 mole of Fe₂O₃ will produce 7.5 mole of CO₂=330g.

Pipes are made of Iron. Iron can be oxidised toFe²⁺.
Fe → Fe²⁺ + 2e^-
but when connected to Mg, which is more electropositive that Fe, Mg is oxidised to Mg²⁺ and in turn reduces Fe²⁺ (rust) to Fe

It is called cathodic protection but at the cost of Mg (sacrified anode).

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.

During aerobic respiration, pyruvic acid which is formed during glycolysis enters mitochondrial matrix. It undergoes oxidative decarboxylation to produce CO₂ and NADH. The product combines with sulphur containing coenzyme A to form acetyl CoA. This reaction is catalysed by an enzyme complex pyruvate dehydrogenase. This step is called link reaction or gateway step as it links glycolysis with Krebs' cycle.

Protonema represents the juvenile stage of moss (funaria). It is much-branched, green filamentous structure formed by the germination of spores, under favourable conditions.
The protonema consists of:
(a) some slender rhizoids.
(b) a number of aerial green prostrate branches bearing small lateral buds which grow up into new moss gametophores.
Hence, the correct answer is Option B

In the leaves of C4 plants, bundle sheath cells are present in the form of rings around the vascular bundle. The arrangement is called kranz and the anatomy is called kranz type of anatomy.
So, the correct option is ‘Leaves’.

• Due to their reduced rate of photorespiration and high rate of photosynthesis, C₄ plants are more efficient than C₃ plants. 
• So the yield of C₃ plants is lower as compared to C₄ plants.

The work of Melvin Calvin is the discovery that the first CO₂ fixation product was a 3-carbon organic acid. He also contributed to working out the complete biosynthetic pathway; hence it was called the Calvin cycle.

Plants follow different pathways in response to environment or phasesof life to form different kinds of structures. This ability is called plasticity. This phenomenon of heterophylly is an example of plasticity.

Skoog and Milleridentified and crystallised the cytokinesis promoting active substance that they termed kinetin.

Each turn of DNA spirals contains 10 base pairs. So, in five turns of DNA total number of Base pair is 5×10=50 base pairs.

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.

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.

• Glucose, fructose, galactose and ribose are all monosaccharides.
• The monosaccharide contained in nucleic acid is ribose and deoxyribose.
• They are pentose sugars.
• Ribose sugar is present in RNA while deoxyribose sugar is present in DNA.

The All India State People's Conference was formed on December 05, 1927, with the efforts of R. Ayyangar, Magillal Kothari and Balwant Rai Mehta.
