Answer: cytoplasm
Explanation:
A cytoplasm is a gel like liquid material that is present within a cell. It is enclosed by a cell membrane. All the organelles such as nucleus, endoplasmic reticulum, mitochondria in a typical eukaryotic cell are embedded inside this liquid material. Cytoplasm consists of molecules for example enzymes which are responsible for breaking down of cellular wastes. It is primarily made up of water and salts. It is responsible for giving the cell it's shape and keeping the organelles in their positions.

Many scientists believe that life on Earth started with simple, single-celled organisms. Therefore, the correct statement is option A.
Single-celled organisms are unicellular organisms that contain only one cell and form the most ancient part of life. They can be prokaryotic or eukaryotic organisms.
Life on earth began with simple, single-celled organisms which are usually prokaryotes, such as bacteria and constitutes the most abundant type of organisms on earth. Prokaryotes lack a nucleus and membrane-bound organelles.
By this time, these single-celled organisms evolved to form more complex organisms. Multicellular organisms first evolved around 1 billion years ago, but they are still considered simple to the organisms present today.
Therefore, simple, single-celled organisms are the first to live on earth billions of years ago.

Observation is the step in the scientific method that requires you to use your senses to obtain information.
In the scientific method, the step that requires you to use your senses to obtain information is called observation. It involves gathering data through your senses, such as seeing, hearing, smelling, tasting, and touching. Observation is important in order to gather accurate and objective information that can be used to form hypotheses and conduct experiments.
