Question Discussion & Solution

The correct option is, i.e. Brain.

• Hypothalamus-
  • The Hypothalamus is a part of Brain that plays a crucial role in many important functions of the Human Body.
  • The hypothalamus is located below the thalamus in the brain.
  • The hormones from the hypothalamus govern physiological functions such as temperature regulation, thirst, hunger, sleep, mood, and the release of other hormones within the body.
  • Hypothalamus regulates the pituitary gland.

Concept

Size of element:

• The atomic size of an element is determined by the atomic radius of an element.
• Atomic radius is the distance between the center of an atom to its outermost (valence) shell having electrons.
• The atomic size of any element is mentioned in form of Atomic radius.
• Unit of Atomic radius is Amstrong (A^o).

Valency of an element:

• Valency is the combining capacity of an atom of an element.
• It is otherwise the valence electrons an atom uses to form a chemical bond.

The molar mass of the element:

• It is defined as the mass of one atom of an element.
• The unit is g/mol.
• For all substances, the molar mass of in g/mol is numerically equal to the formula mass in atomic mass units.

Explanation:

• The maximum number of univalent atoms that may combine with an atom of the element is the Valency.
• The valency of an element is always an integer.
• With regard to covalent compounds, the term valency describes the number of bonds usually formed by each element.
• In ionic compounds, often, the number of positive or negative charges that appear on the atom in its ion helps to state its valency.
• The chemical behavior is largely influenced by the valency of the element.

Hence, Valency of an element is the property that determines an element's chemical behavior.

The correct answer is- ​Jammu&Kashmir.

Key Points

• Chashma Shahi or Chashma-i-Shahi is one of the Mughal gardens built in 1632 AD around a spring by Ali Mardan Khan, a governor of Mughal emperor Shah Jahan
• As per the orders of Emperor Shah Jahan, gifted to his elder son Prince Dara Shikoh.
• The garden is located in the Zabarwan Range, near Raj Bhawan (Governor‘s house) overlooking Dal Lake in Srinagar, Kashmir.

Additional Information

• There is a total of 22 districts in Jammu and Kashmir. 
• Jammu and Kashmir are one of the newly formed 8th Union Territory of India. Jammu is the summer capital of the territory and Srinagar is the winter capital of the territory.
• It was a Region formerly administered by the Government of India as a state from 1954 to 2019.
•  It has been a disputed part between India, China, and Pakistan. After the Independence of India in 1947, the Jammu and Kashmir were divided between India which controlled the regions of (Jammu, Kashmir Valley, and Ladakh) and Pakistan which controlled (Gilgit–Baltistan and Azad Kashmir).
• Jammu and Kashmir was the only state in India with a mostly resident of Muslim Majority.
• It was the only state in India that had special autonomy under Article 370 of the (Constitution of India), according to which no law enacted by the Parliament of India. But on 31st October 2019, Article 370 was scrapped by the Government of India, and Jammu and Kashmir become the Union territory of India.

Here the pattern is,

4320 ÷ 6 = 720,

720 ÷ 5 = 144,

144 ÷ 4 = 36,

36 ÷ 3 = 12,

12 ÷ 2 = 6

The correct answer is the Pie Chart.

• In Ms-Excel, pie charts show percentages adding up to 100%.

​Key Points

• Pie charts
  • ​Pie charts are used to show parts of a whole.
  • Specifically, pie charts illustrate meaningful relationships between percentages or parts of 100%.
  • If the data which we want to display add up to 100%, a pie chart is the best choice.
  • When creating a pie chart, the description of each section is called the category, and the number connected to the category is called the value.

Additional Information

• Column Chart
  • ​A column chart is a graphic representation of data. 
  • Column charts display vertical bars going across the chart horizontally, with the values axis being displayed on the left side of the chart.
  • Column Charts are Used to Compare Data.
• Bar Chart
  • ​Bar graphs are used to compare things between different groups or to track changes over time.
  • A bar chart is a way of summarizing a set of categorical data (continuous data can be made categorical by auto-binning).
• Bubble Chart
  • ​Bubble charts are often used to present financial data.
  • It is an extension of the scatter plot used to look at relationships between three numeric variables.
