The correct answer is human beings do not have cellulose-digesting enzymes.

Explanation:

• Cellulose-rich food substances are a good source of roughage for human beings because human beings do not have cellulose-digesting enzymes.
• Cellulose is a polymeric polysaccharide consisting of only one type of monosaccharide i.e., glucose.
• Cellulose plays an important role in the human body because it is an excellent source of fiber.
• Except for cellulose, enzymes secreted from the human mouth, liver, and stomach can digest any type of sugar.
• Cellulose is digested by the enzyme cellulase which is absent in human beings.
• Humans do not have the cellulose-digesting enzyme (cellulase) to degrade the beta-1, 4 glycosidic bonds of cellulose.
• Thus, it cannot be digested by humans and acts as a good source of roughage.
• Roughage helps our body to get rid of undigested food.

Additional Information

• A balanced diet provides all the nutrients that our body needs, in the right quantities, along with an adequate amount of roughage and water.
• The major nutrients in our food are carbohydrates, proteins, fats, vitamins, and minerals.
• In addition, food also contains dietary fibers and water.
• Carbohydrates and fats mainly provide energy to our body.
• Proteins and minerals are needed for the growth and maintenance of our body.
• Vitamins help in protecting our bodies against diseases.

Concept:

According to Blaise Pascal, a French scientist observed that the pressure in a fluid at rest is the same at all points if they are at the same height and it is termed Pascal’s Law.

i.e., the pressure exerted by the fluid on an object at a certain height will be the same in all direction

and hence it can be expressed as

From the above fig. we can see that the force against area within a fluid at rest will always experience pressure perpendicular to their surface area, and the object will experience equal pressure throughout the surface.

And there are a number of devices, such as hydraulic lift and hydraulic brakes, are based on Pascal’s law. these devices used fluids for transmitting pressure.

In a hydraulic lift, as shown in the figure below, two pistons are separated by the space filled with a liquid

Now as Pascal suggested both the platform will have some pressure although the platform has a different surface area hence the force exerted on surface 2 will be much greater than on force one

$i.e.,P_1=P_2\Rightarrow \frac{F_1}{A_1}=\frac{F_2}{A_2}$

Here,

F1, F2 = force exerted on areas A1 and A2 respectively

P1, P2 = Pressure exerted on areas A1 and A2 respectively

Calculation:

Given:

Mass of car = 2000 kg

Area of cross-section of the piston = 375 cm², g = 9.8 m/s²

Force = Weight of car

⇒ Force on bigger piston = mg

= 2000 × 9.8 = 19600 N

∴ Pressure = 19600 /(375 × 10^-4)

⇒ Pressure, P0= 5.22 × 10⁵ Pa

Pressure 2 m below = P₀ + ρgh

= 5.22 × 105 + 800 × 9.8 × 2

⇒ Pressure 2 m below = 5.37 × 10⁵ Pa

CONCEPT:

• Artificial magnet is the type of magnets that are produced by man under influence of an external magnetic field. Bar magnet, Horseshoe magnet & Electromagnet are examples of artificial magnet.
• Permanent magnets are materials where the magnetic field is generated by the internal structure of the material itself The magnetite of Lodestone is an example of Natural magnets
• When an electric field passes through a conductor it generates a magnetic field
• The hence induced current is used to produce a Temporary magnet
• Earth is a giant magnet with north and south magnetic poles and a magnetic field called the magnetosphere
• It is believed that this magnetic field is produced because of the motion of charged particles due to the convection current inside the earth’s core.

EXPLANATION:

According to the given condition:

• Artificial magnet loses its magnetic field gradually with time hence we can say it is short-lived
• Unlike artificial magnet, the magnetization of Permanent magnet last for a large period of time hence it is Long-lived
• A temporary magnet or electromagnet produces a magnetic field only until the current is induced through the conductor.
• Earth acts as a magnet and it lasts for an infinitely long period.
• Hence the correct option is A.

CONCEPT:

• Stress: Stress is the ratio of the load or force to the cross-sectional area of the material to which the load is applied.
  • The standard unit of stress is N/m2.
• Strain: Strain is a measure of the deformation of the material as a result of the force applied.
  • The strain is a unitless quantity.
• Hooke's law states that within the elastic limit the stress applied on a body is directly proportional to strain produced.

⇒ Strain ∝ Stress

⇒ Strain = E × Stress (Where E = modulus of elasticity)

where σ = stress, F = applied force, A = cross-sectional area, dl = change in length, l = initial length and E = young's modulus of elasticity

CALCULATION:

• We know that the change in length of the material by an externally applied force,

Gravitational force is a weak force. This force exists between each and every object but cannot be felt until the mass of the bodies are not extremely high like planets.

Concept-

• Enzymes are a substance that acts as a catalyst in organisms it regulates the rate at which chemical reactions proceed without itself being altered in the process.
• A catalyst is a substance that is added to increase the reaction rate of the reaction without getting consumed in the process.
• They are high molecular weight compounds made up principally of chains of amino acids linked together by peptide bonds.
• Enzymes can be denatured and precipitated with salts, solvents, and other reagents.
• Enzymes function as organic catalysts. A catalyst is a chemical involved in, but not changed by a chemical reaction. The enzyme speeds up the reaction by lowering the activation energy needed for the reaction to start.

Explanation-

• Vitamins are called micronutrients because they are needed in only very small quantities.
• Vitamins are made up of carbon, hydrogen, and oxygen.
• Vitamins are of two types:
  • Water-soluble vitamins - B, C
  • Fat-soluble vitamins - A, D, E, K
• Vitamins are small organic molecules that make up a part of an enzyme cofactor.
• For the protein's biological activity, a non-protein chemical compound that is required are cofactors of enzymes.

Thereby vitamins act as a part of biological catalyst in the human body.

Additional Information

• Protein is known as the Building Block of our body. Because the main function of the protein in the body is to build and repair cells and tissues. This includes supporting muscle development and all other cells in the body.
  • Sources of protein- Milk, Egg, Meat, Fish Nuts, Pulses, Soyabean, Apples, Apricots, Blueberries, Cherries and Grapefruit. etc.
  • Protein deficiency leads to Kwashiorkor and Marasmus diseases in children
• Carbohydrates are the main source of energy in our body.
  • Sources of Carbohydrates- Cereals, Banana, Mango, Pineapple, Apple, Potato, Sweet potato, Beetroot, etc.
• Fat helps move the vitamins A, D, E, and K through your bloodstream and absorb them into your body and also provide our body energy and provide storage spots for energy into our body, helps in the regulation of body temperature by filling adipose tissue. Hence, fats are important for the overall physiological action of our body.
  • Sources of Fat- Oil, Butter, Ghee, Meat, Fish, Nuts, etc.
  • Excessive fat in our body leads to obesity, high blood pressure, and heart diseases.
• Sugar is soluble carbohydrates. They are sweet-tasting, many of which are used in food.
• There are mainly two types of sugar, i.e simple sugars, and compound sugar.
  • Simple sugars, also called monosaccharides, includes glucose, fructose, and galactose.
  • Compound sugars, also called disaccharides or double sugars, are molecules composed of two monosaccharides joined by a glycosidic bond. Common examples are sucrose, lactose, and maltose.

Solution:

Given, S1 = {x ϵ R ∶ x2 + | x | - 2 = 0} and S2 = {x ϵ R ∶ x2 + x - 2 = 0}

For S₁ : x² + |x| - 2 = 0

Case 1: x ≥ 0

x² + x - 2 = 0

⇒ x² + 2x - x - 2 = 0

⇒ x(x + 2) -1(x + 2) = 0

⇒ (x - 1)(x + 2) = 0

⇒ x = 1 and -2

But according to case 1, x ≠ -2

x = 1

Case 2: x < 0

x² - x - 2 = 0

⇒ x² + x - 2x - 2 = 0

⇒ x(x + 1) -2(x + 1) = 0

⇒ (x - 2)( x + 1) = 0

⇒ x = 2 and -1

But according to case 2, x ≠ 2

x = -1

Hence, S₁ = {1, -1}

For S₂: x² + x - 2 = 0

⇒ x2 + 2x - x - 2 = 0

⇒ x(x + 2) -1(x + 2) = 0

⇒ (x - 1)(x + 2) = 0

⇒ x = 1 and -2

Hence, S₂ = {1, -2}

So, S₁ ∩ S₂ = {1, -1} ∩ {1, -2}

= {1}

∴ The correct option is (4)
