HTET TGT Science Mock Test - 8 - HTET 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.

From Statement 1:

We have, D moved a distance of 40m towards north.

From there he turns to the right and walked for 30m and reached school.

Here, we can’t determine in which direction is D’s home from the school.

From Statement 2:

We have, D is facing south. He turns right and walk for 100m.

After that he turned to the left walk for 50m and reach home.

Here, we can’t determine in which direction is D’s home from the school.

Hence option B is correct.

X × 32 + 8 – 40  = X × 30
2X = 32
X = 16
Hence, Option A is correct.

1st term = 0.5
2nd term = 0.5 * 3 = 1.5
3rd term = 1.5 * 3 = 4.5
4th term = 4.5 * 3 = 13.5

Thus, the missing number is 5th term = 13.5 * 3 = 40.5

Echo -  the repetition of a sound caused by reflection of sound waves.

A reverberation, or reverb, is created when a sound or signal is reflected causing numerous reflections to build up and then decay as the sound is absorbed by the surfaces of objects in the space – which could include furniture, people, and air. 

Sonar is a technique that uses sound propagation to navigate, communicate with or detect objects on or under the surface of the water, such as other vessels. 

The concave surface of the sound board reflects the sound waves of the speaker towards the audience and hence prevents the spreading of sound in various directions. Due to this, sound is distributed uniformly throughout the hall and even the persons sitting at the back of the hall can hear the speech easily.

The instantaneous speed of an object is defined as the speed of the object at any given instant. The instantaneous speed of an object can be determined by determining the average speed over a short distance (and short time), and using this approximation as the instantaneous speed.

The excretory system in humans functions to remove waste products from the body.

Plants do not actively transport waste into the atmosphere; they primarily use methods such as transpiration, storage in vacuoles, and shedding of leaves for excretion.

Energy consumed by the household = 250 units
1 unit of energy = 1 kWh = 3.6 x 10⁶ J
∴ 250 units of energy = 250 x 3.6 x 10⁶ 
= 9 x 10⁸ J.

The earlobe variants found in human population are free and attached.
EXPLANATION:-

• When a pair of guard cells surrounding a stoma receives the signal to open the stomatal pore, it is filled with water, thus changing the cell's shape and opening the pore.
• When guard cells receive a signal to close the stoma, this initiates a loss of water and causes them to shrink and the pore closes.

Thus, option C is correct.

The word Science is derived from the Latin word Scientia which means to know.

• According to Campbell, "Science is a body of useful and practical knowledge and also a method of obtaining it. Science is a purely intellectual activity."

Key Points Mathematics is the branch of science that deals with numbers, involves calculations, and focuses on the study of quantity, shapes, measurements, etc.

• A scientific theory is expressed in mathematical language.
• Mathematics and science have a close relationship that is of crucial and growing importance for both.
• Mathematical knowledge is applied in the study of science.
• According to Roger Bacon, "Mathematics is the gateway and key of all sciences."
• Mathematics is a science of calculations. It is the science of measurement, quantity, and magnitude.
• It deals with quantitative facts and relationships. It is the abstract form of science.

Thus, it is concluded that science cannot be developed without mathematics.

Solutes and solvents are the substance not used only in chemical laboratories, but they are the part of the day to day life. A solution contains only two components, which are solute and solvent. Solvent has the capability of dissolving the solute in a homogenous solution.

Bohr’s Model of Atom

Neils Bohr, a Danish physicist, in 1913 proposed model of atom which rectified the problems left by Rutherford’s Model. He proposed that

(a) Electrons revolve round the nucleus in a fixed orbit.

(b) He called these orbits as ‘stationary orbit’.

(c) Each stationary orbit is associated with fixed amount of energy, thus electrons do not radiate energy as long as they keep on revolving around the nucleus in fixed orbit.
