Question

A zygote develops into a multicellular organism
through
(1) mitosis and specialization
(2) mitosis and meiosis
(3) recombination and communication
(4) genetic engineering and natural selection

Answer 1

Mitosis and Specialization

Mitosis is a process that occurs during cell cycle which involves the division of a cell to produce two new cells that are identical to itself. Also, it is the splitting of DNA in the cell’s nucleus into two equal sets of chromosomes. Furthermore, mitosis consists of four basic phases which were prophase, metaphase, anaphase and telophase.

Cell Specialization is a process where generic cell changes into specific cells for the purpose of specific task within the body. Furthermore, they are very important in the development of embryos.

Answer 2

Answer:

The correct answer is option A, mitosis and specialization

Explanation:

Mitosis causes the cells to divide and multiply in numbers. The cell produced are similar to the parents cell and have same number of chromosome. The major role of mitosis is to allow the body to grow fast and also it replaces the dead cells with the new ones.  

Cell specialization is the arrangement of cells in a way that they form special structures /tissue and organs that are important to perform specific body functions.
