Vitamin K is responsible for the coagulation of blood also known as blood clotting.
  • Vitamin K helps in the process of blood coagulation as it acts as a cofactor for the enzymes which are required for maintaining the blood clotting factors, namely Protein C, S, and factors VII, IX,and X.
  • Vitamin K is found in the following foods: Green leafy vegetables, such as kale, spinach, turnip greens, collards, Swiss chard, mustard greens, parsley, romaine, and green leaf lettuce.

  • c)
    6%
  • d)
    8%

YERUVA SAI answered  •  2 hours ago
Let the sum be ‘x’ and the rate be ‘r’
∴ According to the 1st given condition,

 
According to the 2nd given condition,
⇒ 40 = (x × 2 × r)
∴ xr = 20
Substituting in equation (1) we get,
⇒ 41 = 20 × (2 + r)
∴ r = 0.05
∴ The required rate is 5%

TUSHAR JALAN answered  •  2 hours ago
Answer: Option (4) is correct.
Solution: Labour laws and excessive regulations assumed to protect the labor are the cause of slow employment growth in high paying, organized sector. Companies find it difficult to pay the minimum wages and ask them to work only up to some time limit fixed by the respective country’s government. As a result, there is less foreign investment leading to a downturn of the economy. Therefore, assertion is completely false by definition only and reason, as stated above, is true. Therefore A is false but R is true.

A ladder 13 feet long stands upright against a wall. How far must the bottom of the ladder be pulled out so as to lower the top by a foot ?
  • a)
    6 feet
  • b)
    5 feet
  • c)
    3 feet
  • d)
    1 feet
Correct answer is option 'B'. Can you explain this answer?

ATUL RANJAN answered  •  2 hours ago
Let bottom B of the ladder be pulled out be x feet from the wall so that the top A is lowered by 1 foot.
BQ2 = AB2 – AQ2
⇒ x2 = 132 – 122
= 169 – 144 = 52
∴ x = 5 feet

ABHISHEK YADAV answered  •  2 hours ago
Simple multiplication 3 × 25 = 75. Bracket takes priority over division, multiplication, addition or subtraction.
Hence, (3 × 25 ) ÷ 5 - 20 × 4 + 75 = 75 ÷ 5 - 20 × 4 + 75 = 15 - 20 × 4 + 75.
Multiplication takes priority over addition or subtraction.
Hence, 15 - 20 × 4 + 75 = 15 - 80 + 75.
Addition takes priority over subtraction.
Hence, 15 - 80 + 75 = 90 - 80 = 10

Follow BODMAS rules to solve the equation
Step -1: The part of the equation containing 'Brackets' must be solved first, and in the bracket,
Step -2: Any mathematical 'Of' or 'Exponent' must be solved next,
Step -3: Next, the parts of the equation that contain 'Division' and 'Multiplication' are solved
Step -4: At last, the part of the equation that contains 'Addition' and 'Subtraction' should be solved.
⇒ 2112 + 692 × 2 – 1111 × 5 + 7324 × 8 = ?
⇒ 2112 + 1384 – 5555 + 58592 = ?
⇒ ? = 62088 – 5555 = 56533
∴ ? = 56533.

Given,
x + 4/x = 4
⇒ x2 + 4 = 4x
⇒ x2 - 4x + 4 = 0
⇒ (x - 2)2 = 0
⇒ x = 2
∴ (x6 + 1) = 26 + 1 = 64 + 1 = 65

Nature of bond present in the molecule of Nitrogen gas will be

  • b)
    Single covalent
  • c)
    Double covalent

    Triple covalent
Correct answer is option 'D'. Can you explain this answer?

TOMS THOMAS answered  •  13 hours ago
Covalent bonds are formed by atoms sharing electrons to form bonds that hold the atoms together in a molecule. This type of bond usually formed between two non–metallic elements. Nitrogen, being a non-metal, has 5 electrons is its outer shell. So to make the atom count 8 in order to get stabilized, 2 nitrogen atom would share 3 atoms each with each another, thus forming 3 pairs. These bonds which are then formed are known triple covalent bond.

Follow BODMAS rule to solve this question, as per the order given below,
Step-1- Parts of an equation enclosed in 'Brackets' must be solved first, and in the bracket,
Step-2- Any mathematical 'Of' or 'Exponent' must be solved next,
Step-3- Next, the parts of the equation that contain 'Division' and 'Multiplication' are calculated,
Step-4- Last but not least, the parts of the equation that contain 'Addition' and 'Subtraction' should be calculated.
Given expression is,
⇒ (756 + 62 × ?) ÷ 3 = 57 × 9 + 49
⇒ (756 + 62 × ?) ÷ 3 = 513 + 49
⇒ (756 + 62 × ?) ÷ 3 = 562
⇒ (756 + 62 × ?) = 562 × 3
⇒ (756 + 62 × ?) = 1686
⇒ 62 × ? = 1686 - 756
⇒ 62 × ? = 930
⇒ ? = 930 / 62
⇒ ? = 15
