I need help with question 5.

Answer;

-Single

All organisms begin life as a single cell

Explanation;

-Every living organism begins life as a single cell. Unicellular organisms may stay as one cell but they grow too. Multicellular organisms add more and more cells to form more tissues and organs as they grow. Growth and development of living organisms are not the same things.

-In unicellular organisms such as bacteria, mitosis is a type of asexual reproduction, making identical copies of a single cell. In multicellular organisms, mitosis produces more cells for growth and repair.

The complete statement will be "All organisms begin life as a single cell."

How to complete the blank?

The statement highlights the concept of cellular reproduction and development in living organisms. Every organism, regardless of its complexity or size, originates from a single cell, commonly referred to as a zygote.

Sexual reproduction, which involves the fusion of sperm and egg cells, is one method by which organisms begin life as a single cell. During fertilization, the sperm and egg cells combine their genetic material, resulting in the formation of a zygote. This zygote then undergoes a series of cell divisions through a process called mitosis, giving rise to multiple cells and initiating the development of a new organism.

In the case of asexual reproduction, a single parent organism produces offspring without the involvement of gametes (sperm or egg cells). This can occur through various mechanisms such as binary fission, budding, or fragmentation. Regardless of the method, a single parent cell is responsible for initiating the development of the offspring.

From this single cell, subsequent cell divisions and differentiation processes occur, leading to the formation of various tissues, organs, and ultimately, a fully developed organism. The cells generated during development specialize and take on specific roles, such as forming tissues, muscles, nerves, and organs, enabling the organism to function and grow.

Therefore, regardless of the species or reproductive mode, all organisms initially begin their life cycle as a single cell, from which they undergo complex processes of cellular reproduction, growth, and differentiation to reach their fully developed state.

Then the complete statement is  "All organisms begin life as a single cell."
