Correct Answer: C. merit system

Correct Answer: D. manufacturing account

Explanation

Carriage inwards on raw materials is recorded in the manufacturing account. It is added to the opening stock of raw materials and purchase of raw materials.

Correct Answer: D. 14

Explanation

T₁, T₂, T₃

2, -9, -20 .... -141

l = a + (n - 1)d

first term, a = 2

common difference d = T₃ - T₂

= T₂ - T₁

= -20 - (-9) = -9 -2

= -20 + 9

= -9 -2

= -20 + 9

= -11

-11 = -11

d = -1

last term l = -141

-141 = 2 + (\(\cap\) - 1) (-11)

-141 = 2 + (-11 \(\cap\) + 11)

= 2 - 11\(\cap\) + 11

-141 = 13 - 11\(\cap\)

-141 - 13 = -11\(\cap\)

-154 = -11\(\cap\)

\(\cap\) = \(\frac{-154}{-11}\)

\(\cap\) = 14

Correct Answer: D. 8

Explanation

5x + 3y=4

5x-3y= 2

Using elimination method

5x + 3y=4 → 5x + 3y=4

-[5x-3y= 2] → -5x +3y= -2

6y = 2

y → 1/3 and x = 3/5

solving (25x\(^2\) -9y\(^2\))

25 * [3/5]\(^2\) -9 * [1/3]\(^2\)

25 * \(\frac{9}{25}\) - 9 \(\frac{1}{9}\)

9 - 1 = 8

Correct Answer: D) mitochondrion

Explanation

In Biology, respiration is the process by which cells produce energy. The question is asking us which organelle is responsible for tissue respiration. The options given are endoplasmic reticulum, ribosome, golgi body, and mitochondrion. The correct answer is Option D, mitochondrion. Mitochondria are often referred to as the powerhouses of the cell because they are responsible for producing most of the energy required by cells. They do this by breaking down glucose and other nutrients through a process called cellular respiration. This process takes place in the mitochondria and generates energy in the form of ATP. The other options given, such as endoplasmic reticulum and golgi body, are also important organelles in the cell, but they are not directly involved in tissue respiration. The ribosome is responsible for protein synthesis, not energy production. It's important to understand the functions of different organelles in the cell to have a good grasp of how cells work. Mitochondria are involved in various cellular processes, including cell signaling, cell differentiation, and cell death. For more information on this topic, please see the recommended textbooks.

Correct Answer: A) chyme

Explanation

After food is swallowed, it travels down the esophagus and enters the stomach. In the stomach, the food is mixed with digestive juices and broken down into smaller particles. The resulting mixture is called chyme. Chyme is a partially digested, semi-liquid substance that is ready to leave the stomach and enter the small intestine for further digestion and absorption of nutrients. Option A, chyme, is the correct answer to the question. Options B, C, and D are incorrect. Curb and paste are not terms used to describe partially digested food, while glycogen is a form of glucose stored in the liver and muscles. It is important to note that the stomach plays a crucial role in the digestive system. It not only breaks down food into chyme but also kills harmful bacteria and viruses that may be present in the food. The stomach also releases hormones and signals to regulate the digestive process and appetite.
