The smallest item in the list would be organelles. Organelles are tiny structures within a cell, that help it to function. Example of organelles are-- nucleus, mitochondria, cell membrane to name a few. Cells are the basic unit of structure and function of all living things, therefore, cells would have to be placed second. They are microscopic. A group of similar cells that work together to perform a specific function, is known as a tissue. Therefore, tissue is next largest. Examples of tissues include, muscle tissue, epithelial tissue, adipose tissue. When different types of tissues work together to perform a function in the body, this group of tissues forms an organ. An example of an organ is the heart. Inside the heart are many types of tissue-- cardiac muscle,nerve, blood, connective, etc. The job it performs is to pump blood. When various organs work together to perform a specific function in the body, this makes up a system. An example is the circulatory system. In this system are many organs that work together. Arteries, veins, capillaries and heart are all part of the circulatory system. Its job is to circulate blood containing nutrients and oxygen to cells and to pick up cellular wastes. All the systems of the body comprise the organism. An organism is a living thing. It can be as tiny as a microbe, or a complex as a human. When referring to a multicellular organism, the correct order from smallest to largest is-- organelle, cell, tissue, organ, system, organism
Option B) Water from the red blood cell will diffuse into the solution.
<h2>Explanation:</h2>
This is due to Osmosis.
<u>Osmosis</u> is the movement or transfer of water or other solvent through a plasma membrane from a region of low solute concentration to a region of high solute concentration, by which equal concentration is achived on the both sides. Osmosis is passive transport which means it does not require any energy.
The concentration of water is high and concentration of solute(Proteins and sugar) is low in RBC(red blood cell) as compared with solvent(i.e given Aqueous solution) and hence the the water will expel(comes out in the external solution) from the the RBC, due to Osmosis.
Result: Water will diffuse from RBC into the solution.
The astrocytes are components of the central nervous system that provide the necessary supports that the brain needs to perform vital tasks such as learning and other daily activities. They are typical cell types in the central nervous system that aid blood flow in the brain as well as the migration of neurons.
This cells primarily produce mucus and are frequently clustered into small glands found usually in the mucus membranes. They commonly lines the proximal and distal portion of the digestive tract. Large number of this cell can found in the mouth which moisten and keep the oral cavity moist. Stomach also have large number of mucous cells which help to protect the organ from the gastric juices it produce.
