The diagram below shows how biotechnology can be used to produce a cow with a desired characteristic.

here are the answers to the biotechnology questions:

QUESTION 3.2

3.2.1 What is meant by biotechnology?
Biotechnology is the use of living organisms or their products to create or modify products for specific uses, often involving genetic engineering.

3.2.2 Name the biotechnological process represented in the diagram above.
The process represented is cloning (specifically, somatic cell nuclear transfer).

3.2.3 Give ONE reason why an ovum is used during this process.
An ovum (egg cell) is used because its cytoplasm contains essential organelles and factors required for the development of an embryo.

3.2.4 Why is an electric shock applied to the 'ovum' at Z?
The electric shock is applied to stimulate the fusion of the inserted nucleus with the enucleated ovum and to activate the cell to begin dividing, mimicking fertilization.

3.2.5 State why the offspring produced is phenotypically different to the surrogate mother.
The offspring is phenotypically different from the surrogate mother because its genetic material (DNA) comes entirely from the donor nucleus of Cow B, not from the surrogate mother (Cow A).

3.2.6 Give ONE possible disadvantage of having all the cows on a particular farm produced through this process.
A possible disadvantage is the lack of genetic variation among the cloned cows, making them all susceptible to the same diseases or environmental changes, which could lead to a widespread loss of livestock.
