Correct Answer: DNA fingerprinting
Correct Answer: Urochrome
Correct Answer: Mitral
Correct Answer: Green plants
Correct Answer: Nucleus
Correct Answer: O
Explanation:
The persons with 'O' blood group do not have antigens in the red corpuscles. So that blood will not cause agglutination of corpuscles if mixed with any type of blood. So group 'O' persons are called universal donors.
Correct Answer: Cell biology
Explanation:
The branch of biology that studies the different structures and functions of the cell is called Cell Biology or Cytology.
A cell is the smallest unit of life that can replicate independently, and cells are often called the "building blocks of life"
Cell Biology deals with :
Correct Answer: Breaking down food
Explanation:
Nutrients are necessary for break down the food and supply energy to the organisms and to carry out essential life functions.
