Consider the differential equation \(x d y=(x+y) d x\). Which of the following are true?
(A) It is a homogenous differential equation
(B) It is a differential equation of order 2
(C) The general solution of the differential equation contains 2 arbitrary constants
(D) Integrating factor of differential equation is \(\frac{1}{x}\)
(E) Degree of the differential equation is not defined
Choose the correct answer from the options given below:
- A (A), (B) and (C) only
- B (A), (D) and (E) only
- C (A) and (D) only
- D (B) and (C) only
Answer & Solution
Correct Answer
(C) (A) and (D) only
Step-by-step Solution
Detailed explanation
\(x dy = (x+y) dx \Rightarrow \frac{dy}{dx} = \frac{x+y}{x} = 1 + \frac{y}{x}\) (A) Homogeneous: \(f(x,y) = 1 + \frac{y}{x}\). \(f(tx,ty) = 1 + \frac{ty}{tx} = 1 + \frac{y}{x} = f(x,y)\). True. (B) Order: Highest derivative is \( \frac{dy}{dx} \). Order is 1. False. (C)…

Recombinant DNA Technology Asexual reproduction preserves the genetic information, while sexual reproduction permits variation. Traditional hybridization procedures used in plants and animals breeding very often lead to inclusion and multiplication of undesirable genes along with the desired genes. The techniques of genetic engineering, which include creation of recombinant DNA, use of gene cloning and gene transfer, overcome this limitation and allow us to isolate and introduce only one or a set of desirable genes without introducing genes into the target organism.
