Question Discussion & Solution

The first letter in each group is obtained by adding five letters to the first letter of the previous group.

W + 5 = B, B + 5 = G, G + 5 = L, L + 5 = Q, Q + 5 = V

The second letter in each group is opposite to the first letter of that group according to their positional value.

W ↔ D, B ↔ Y, G ↔ T, L ↔ O, Q ↔ J, V ↔ E

The numbers in in each group are obtained by adding two and its multiple at each step respectively.

4 + 2 = 6, 6 + 4 = 10, 10 + 6 = 16, 16 + 8 = 24, 24 + 10 = 34

The correct answer is Multiple fission.

• The ability of a cell to divide into several cells during reproduction in Plasmodium is called multiple fission.​

Key Points

• Cell- It is the structural and functional unit of life.
  • It is first discovered by Robert Hooke in 1665.
• According to Schwann and Schleiden, All new daughter cells are formed from pre-existing cells.
• Reproduction is a distinctive characteristic of Living Organisms.
  • Living organisms reproduce and give rise to similar organisms of the same species.
• Fission is the process in which a single cell divides into two or more than two cells.
  • When a single cell divides into two cells called Binary fission.
  • When a single cell divides into many cells called Multiple fission.

Important Points

• Plasmodium after feeding on RBCs undergoes asexual reproduction which is called schizogony or multiple fission. 
• In multiple fission, plasmodium divides into many cells.

​

• The Best example of Run time polymorphism is Function Overriding
• Function Overloading is the example of Compile time polymorphism
• Protected is an Access modifier  

Important Point

Compile-time polymorphism

It means binding is occurring at compile time It can be achieved through static binding. If a class has multiple methods having the same name but different in parameters, it is known as Method Overloading.

Run time polymorphism

At run time we came to know which method is going to invoke It can be achieved through dynamic binding. If subclass (child class) has the same method as declared in the parent class, it is known as method overriding

Access Modifiers

It specifies the accessibility or scope of a field, method, constructor, or class. There are three types of Access modifiers

• Public: The methods or data members that are declared as public can be accessed anywhere in the program.
• Private:  The methods or data members declared as private are accessible only within the class in which they are declared.
• Protected: The methods or data members declared as protected can accessible within the same class or class which is inherited from it.

The correct answer is Vitamin B1.

Key Points

• When rice is produced and not polished it is called brown rice. 
• Brown rice is rich in Vitamin B1. 
• When brown rice is polished, rice loses many vitamins and minerals including Vitamin B1 through the bran.
• Vitamin B1 also called thiamine is an essential vitamin, a deficiency of which is known to cause beriberi.

Additional Information

The correct answer is All of the above.

Key Points

• Living organisms share characteristics such as the ability to move and reproduce.
• There are different types of living organisms including plants, animals, fungi, bacteria, and protoctists.
• Characteristics of living organisms:
  • Movement - they can move and change their position.
  • Reproduction – they can make more of the same kind of organism as themselves.
  • Sensitivity – they can detect or sense stimuli and respond to them.
  • Growth - they can permanently increase their size or dry mass by increasing the number or size of their cells.
  • Respiration – they can create chemical reactions that break down nutrient molecules in living cells to release energy.
  • Excretion – they can excrete toxic materials, waste products of metabolism, and excess substances.
  • Nutrition - they can take in and absorb nutrients such as organic substances and mineral ions. These nutrients contain the raw materials or energy needed for growth and tissue repair.

  Additional Information

• Cells are the building blocks of every living organism.
• Two-thirds of a cell is composed of water and is made up of biological molecules such as proteins and lipids.
• They provide a definite structure to the body, help to break down food, and release energy which is used up by our body to perform multiple tasks throughout the day.
