The correct answer is 300%.

Key Points

• Crop rotation intensity refers to the number of times crops are planted and harvested on the same piece of land within a year.
• This specific rotation provides an effective balance of nutrients, improves soil health, and minimizes pest and disease buildup.
• The Maize-Potato-Mung bean rotation is commonly practiced in regions where conditions support all three crops in a single agricultural calendar year.
• Cropping intensity is calculated as the ratio of the total cropped area to the total cultivable area, expressed as a percentage. It indicates how intensively the land is being used for crop production over a year.
• The cropping intensity can be calculated by using the following formula:

$\text{Cropping Intensity} = \left( \frac{\text{Total Cropped Area}}{\text{Total Cultivable Area}} \right) \times 100$

In the case of Maize-Potato-Mung bean:

• Maize, Potato, and Mung bean are grown sequentially within a single year on the same field.
• This means the field is being used three times in a year.

So, for a given area of land, the total cropped area over the year would be:

$\text{Total Cropped Area} = (1 \text{ crop of Maize} + 1 \text{ crop of Potato} + 1 \text{ crop of Mung bean}) \times \text{Total Cultivable Area}$

$\text{Total Cropped Area} = 3 \times \text{Total Cultivable Area}$

Therefore, the cropping intensity would be

$\text{Cropping Intensity} = \left( \frac{3 \times \text{Total Cultivable Area}}{\text{Total Cultivable Area}} \right) \times 100$

Cropping Intensity = 300%

Additional Information

Given:

Side of hexagon (a) = 2√3 cm

Formula used:

Area of hexagon = (3√3/2) × a²

Calculation:

Area = (3√3/2) × (2√3)²

⇒ Area = (3√3/2) × (4 × 3)

⇒ Area = (3√3/2) × 12

⇒ Area = 18√3 cm²

∴ The correct answer is option (4).

Given:

2x + (2/x) = 3

Formula Used:

To find the value of x³ + (1/x³) + 2, we use the following identity:

[x + (1/x)]³ = x³ + (1/x³) + 3[x + (1/x)]

Calculations:

2x + (2/x) = 3

x + (1/x) = 3/2

⇒ Use the identity:

[x + (1/x)]3 = x3 + (1/x3) + 3[x + (1/x)]

⇒ (3/2)3 = x3 + (1/x3) + 3 × (3/2)

⇒ 27/8 = x3 + (1/x3) + 9/2

⇒ x3 + (1/x3) = (27/8) - (9/2)

⇒ x3 + (1/x3) = -9/8

⇒ Add 2 to the result:

x3 + (1/x3) + 2 = (-9/8) + 2

⇒ x3 + (1/x3) + 2 = 7/8

∴ The correct answer is option (4).

Given:

Quadratic equation: 2x² + px + 4 = 0

One root (x₁) = 2

Formula used:

If the roots of a quadratic equation are x₁ and x₂, then:

Sum of roots = -b/a

Product of roots = c/a

Calculations:

Given that one root is x₁ = 2, let the other root be x₂.

Using the formula for product of roots:

⇒ x₁ × x₂ = c/a

⇒ 2 × x₂ = 4/2

⇒ x₂ = 2 / 2

⇒ x₂ = 1

∴ The other root is 1, and the correct answer is option (3).

The correct answer is War.

Key Points

• According to Thomas Malthus, war is one of the key "positive checks" that limits population growth by reducing the population through mortality.
• Malthus categorized population control measures into two types: preventive checks (e.g., moral restraint, delayed marriage) and positive checks (e.g., famine, disease, war).
• War was emphasized as a natural and inevitable mechanism to bring population levels back in alignment with the available resources.
• Malthus argued that without such "positive checks," human population growth would outpace food production, leading to widespread scarcity and suffering.
• His theory is based on the principle that population grows geometrically while food supply grows arithmetically, creating a gap that needs to be corrected by such checks.

Additional Information

• Thomas Malthus and his Theory:
• Thomas Robert Malthus was an 18th-century British economist and demographer.
• In his famous work, An Essay on the Principle of Population (1798), he proposed that population growth, if unchecked, would lead to resource depletion.
• He introduced the concepts of "preventive checks" and "positive checks" to manage population growth.
• Preventive Checks:
• These are measures to reduce birth rates, such as moral restraint, delayed marriage, and birth control.
• Malthus supported moral restraint as the most ethical preventive measure.
• Positive Checks:
• These are natural and man-made factors that increase death rates, including famine, disease, and war.
• Malthus believed these checks were necessary to prevent overpopulation and maintain the balance between population and resources.
• Criticism of Malthusian Theory:
• Modern economists argue that technological advancements in agriculture and resource management have disproved Malthus's dire predictions of widespread famine and resource scarcity.
• Critics also highlight that social, economic, and political factors greatly influence population dynamics beyond Malthus's simplistic model.

• This method ensures high accuracy and is ideal for tailoring garments to fit individual body shapes perfectly.
• Drafting is widely used in professional sewing, fashion design, and clothing construction.
• Why it's the correct answer:
• Unlike other methods such as draping, drafting uses mathematical precision based on measurements rather than visual adjustments.
• It is considered one of the fundamental techniques in garment pattern-making.

Additional Information

• Draping
• Draping is a method of creating patterns by manipulating fabric directly on a dress form or mannequin.
• It is more artistic and visual compared to drafting, and it allows designers to experiment with fabric flow and fit.
• While draping is suitable for creative designs, it may not provide the same level of measurement precision as drafting.
• Clothing Construction
• Clothing construction refers to the process of assembling garment pieces to create finished clothes.
• It involves techniques such as sewing, hemming, and adding embellishments.
• While clothing construction is an essential part of garment creation, it is not a method of creating patterns.
• Pattern-making Techniques
• There are three primary methods of pattern-making: drafting, draping, and flat pattern making.
• Flat pattern making involves modifying existing patterns to create new designs, whereas drafting starts from scratch using body measurements.

The correct answer is - Structural design

Key Points

• Structural design
• A structural design refers to the inherent design or construction of an object, which does not rely on external decoration.
• In the context of clothing, it is the shape, fit, and structure of the garment itself, rather than embellishments like embroidery or prints.
• For example, a plain dress with no additional decorative elements falls under this category because its design is defined purely by its construction.
• Structural design focuses on the functional aspects of a garment, such as seams, darts, and pleats, which contribute to its form and utility.

Additional Information

• Decorative design
• This type of design refers to external additions or enhancements made to a garment, such as embroidery, appliqué, or lace.
• Unlike structural design, decorative design does not affect the actual shape or structure of the garment but enhances its aesthetic appeal.
• Surface design
• A subset of decorative design, surface design involves embellishments applied to the surface of the fabric, such as prints, painting, or embossing.
• Surface designs are typically added after the garment has been constructed to enhance its visual appeal.
• Difference between Structural and Decorative Design:
• Structural design is an integral part of the garment's construction and focuses on the shape and fit.
• Decorative design, on the other hand, is an added feature that enhances the appearance but is not essential to the garment's functionality.

The correct answer is - 28 days

Key Points

• Ovulation occurs on day 14 of a standard 28-day menstrual cycle.
• During this cycle, the ovum matures and is released for potential fertilization.
• This process is regulated by hormonal changes, particularly the surge in luteinizing hormone (LH).
• The 28-day cycle is considered the average duration for menstruation, although it can vary slightly among individuals.
• The release of the ovum, also known as ovulation, typically occurs 14 days before the next menstruation.

Additional Information

• Hormonal Regulation
• The menstrual cycle is controlled by the interaction of four hormones:
• Follicle-Stimulating Hormone (FSH): Stimulates follicle development in the ovary.
• Luteinizing Hormone (LH): Triggers ovulation and supports the development of the corpus luteum.
• Estrogen: Prepares the uterine lining for implantation and regulates the release of LH.
• Progesterone: Maintains the uterine lining post-ovulation for potential pregnancy.
• Phases of the Menstrual Cycle
• Follicular Phase (Days 1-14)
• Follicles in the ovary mature, driven by FSH.
• Estrogen levels rise, leading to thickening of the uterine lining.
• Luteal Phase (Days 15-28)
• After ovulation, the corpus luteum secretes progesterone to maintain the uterine lining.
• If fertilization does not occur, hormone levels drop, and menstruation begins.
• Variation in Cycle Length
• While 28 days is the average, cycles can range from 21 to 35 days.
• Ovulation typically occurs 14 days before the start of the next cycle, regardless of its length.

The correct answer is - 2, 4, 3, 1

Key Points

• Chronological order of events in human reproduction
• Ovulation: This is the release of a mature egg from the ovary. It is the first step in the process of reproduction.
• Fertilization: This occurs when the egg and sperm fuse in the fallopian tube to form a zygote.
• Sex determination: The sex of the baby is determined at the time of fertilization based on the type of sperm (X or Y chromosome) that fertilizes the egg.
• Implantation: The zygote develops into a blastocyst, which implants itself into the uterine wall. This is the final step in the sequence.
• The correct sequence is Ovulation → Fertilization → Sex determination → Implantation, as given in Option 2.

Additional Information

• Ovulation
• It is triggered by a surge in the luteinizing hormone (LH).
• Occurs approximately on the 14th day of a regular 28-day menstrual cycle.
• Fertilization
• Occurs in the ampulla of the fallopian tube.
• The zygote formed is a single cell that undergoes multiple divisions to form a blastocyst.
• Sex determination
• Determined by the type of sperm (X or Y chromosome) that fertilizes the egg.
• XX results in a female child, while XY results in a male child.
• Implantation
• The process by which the blastocyst attaches to the uterine wall.
• Occurs approximately 6-10 days after fertilization.

The correct answer is - stimulates breathing process

Key Points

• Role of the baby's first cry
• The first cry of a newborn is crucial as it stimulates the breathing process.
• During birth, the baby's lungs are filled with fluid. The first cry helps to clear the fluid and allows air to enter the lungs.
• This action initiates the process of independent breathing, which is vital for the newborn's survival outside the womb.
• The cry also helps to expand the alveoli (tiny air sacs in the lungs) for the first time, enabling oxygen exchange.
• Importance of oxygenation
• The newborn's body begins to rely on its lungs for oxygenation, replacing the oxygen supply it received through the placenta during pregnancy.
• Ensuring proper oxygen flow is critical for the baby's organs, especially the brain, during the initial moments after birth.

Additional Information

• Other functions of the first cry
• While the main purpose is to stimulate breathing, the cry also helps to:
• Increase blood flow to the lungs, aiding in oxygen exchange.
• Facilitate the closure of fetal circulatory shunts, such as the ductus arteriosus, which redirects blood flow to the lungs after birth.
• Misconceptions
• The baby's first cry is not an indicator of hunger or pain but a natural reflex to adapt to the external environment.
• This reflex is triggered by the sudden change in temperature and pressure as the baby exits the womb.
• Medical significance
• If a baby does not cry immediately after birth, it may indicate respiratory distress or other complications, requiring medical attention.
• Doctors may use techniques like suctioning or gentle stimulation to encourage the baby to cry and initiate breathing.

The correct answer is - law of multiple response

Key Points

• Thorndike's secondary laws are additional principles that supplement his three primary laws of learning (law of readiness, law of exercise, and law of effect).
