Q. At home my mother gives ___________ cooking lessons.
a)

Gunjan Lakhani answered |
To solve this question, we need to understand the meaning of the sentence and determine who is receiving the cooking lessons at home.
The sentence structure is "my mother gives _______ cooking lessons", which implies that the cooking lessons are being given to someone.
The correct option to fill in the blank is "C:
me
". Here is the explanation of why it is the correct option:- The pronoun "me" is the objective form of the first-person singular pronoun "I".
- In this sentence, "me" is the object of the verb "gives", indicating that someone is receiving the cooking lessons.
- Since the sentence is referring to "my mother" giving cooking lessons, it is logical to assume that the person receiving the lessons would be someone else, in this case, the speaker, who is represented by the pronoun "me".
In summary, the correct option to fill in the blank is "C:
me
", as it correctly identifies the person who is receiving the cooking lessons from the speaker's mother.‘सु’ उपसर्ग वाला कौन-सा शब्द नहीं है- a)सुपात्र

Gunjan Lakhani answered |
To find the median height, first arrange the heights in ascending order:
6000 m, 6500 m, 7500 m, 8200 m, 8600 m, 8800 m.
Since there are six values, the median is the average of the 3rd and 4th values:
(7500 + 8200) / 2 = 7850 m.

Step 1: Substitute the Value of x
To find the value of the expression 5x² + 2x - 3 when x = 5, first, substitute 5 in place of x:

Mehul Banerjee answered • Sep 30, 2024 |
Function of Aldosterone
Aldosterone is a crucial hormone produced by the adrenal glands. It plays a significant role in regulating blood pressure and maintaining electrolyte balance in the body.
Function of Angiotensin II
Angiotensin II is a peptide hormone that plays a key role in the body's blood pressure regulation and fluid balance.
In summary, both aldosterone and angiotensin II work together to maintain blood pressure and fluid balance, ensuring the body functions optimally.

- Maintains Blood Pressure: By retaining sodium, aldosterone helps increase blood volume, which in turn raises blood pressure. This mechanism is vital for ensuring adequate blood flow to organs.
- Stimulates Water Retention: As sodium is reabsorbed, water follows, leading to increased blood volume and further contributing to blood pressure regulation.
Function of Angiotensin II
Angiotensin II is a peptide hormone that plays a key role in the body's blood pressure regulation and fluid balance.
- Vasoconstriction: Angiotensin II causes blood vessels to constrict, which increases resistance and raises blood pressure.
- Stimulates Aldosterone Secretion: It triggers the adrenal glands to release aldosterone, further promoting sodium retention and potassium excretion.
- Enhances Thirst Response: Angiotensin II stimulates the thirst center in the brain, encouraging fluid intake to help restore blood volume and pressure.
- Promotes Antidiuretic Hormone (ADH) Secretion: It increases the release of ADH from the pituitary gland, leading to water reabsorption in the kidneys.
In summary, both aldosterone and angiotensin II work together to maintain blood pressure and fluid balance, ensuring the body functions optimally.

Which rational number should be added to -7/11 so as to get 4/7?
|
Nayanika Chauhan answered |
To find the rational number that should be added to -7/11 to get 4/7, you can use the following steps:
1. Write the two rational numbers as fractions with a common denominator:
-7/11 = -49/77 and 4/7 = 28/77
2. Add the two fractions:
(-49/77) + (28/77) = -21/77
3. Simplify the result, if possible:
-21/77 = -3/11
Therefore, the rational number that should be added to -7/11 to get 4/7 is -3/11.

In order to cut down expenditure, Jess decided to not stay in a hotel, but go camping instead.
Explanation:
The correct answer is option A, which states that Jess decided not to stay in a hotel but go camping instead. Here's why:
- Jess wants to reduce expenses, so she decides to find a cheaper alternative to staying in a hotel.
- Camping is usually more affordable than staying in a hotel, as it involves setting up a tent or using a recreational vehicle in a designated camping area.
- By choosing camping, Jess can enjoy nature, outdoor activities, and a lower cost of accommodation.
- Camping often allows individuals to immerse themselves in natural surroundings and have a unique experience compared to staying in a hotel.
- The other options (B, C, and D) suggest different accommodations such as a camp, resort, or boathouse, but none of these options align with Jess's goal of cutting down expenditure.
In conclusion, to reduce costs, Jess decides to forgo staying in a hotel and instead opts for camping.
