The groups of small cells better than one large cell at moving material in and out because they have a greater surface-to-volume ratio.
<u>Option: A</u>
<u>Explanation:</u>
This happened so as these smaller cells, unlike bigger cells, can quickly and willingly enter and move through the membranes of other cell membranes and permeable coverings. For these smaller and mini cells, it is also important to penetrate and move effectively, distribute and transport products and materials such as nutrients, oxygen and waste across the body without requiring enough energy and saving less space. They are cheaper, more effective and use less room for simple reasons, and most notably deplete less resources.
Answer:
One could be in the cell. The cell respires, thus producing carbon dioxide in it. So the concentration builds up in the cell. Diffusion is the net movement of particles from a region of high concentration to a region of low concentration, and the carbon dioxide concentration outside the cell is less, therefore the carbon dioxide molecules moves outs of the cell.
Another scenario is when perfume is sprayed into the air. The perfume particles collides with the air particles (lower or no concentration of perfume). This process goes on and on. This is diffusion since the concentration perfume particles collides with the less concentrated particles of perfume.
As the head organ in the body which controls, monitors, supervises and influences the different organ system in the body and of the individual -characteristics, personality, traits, cognition, perception, intelligence, sensation and motor responses. The brain controls the endocrine system by its part, located somwhere in the medial temporal lobe called the hypothalamus, the master gland of the body. The hypothalamus influences every gland secretion and hormonal function that preceeds and proceeds in the body of an organism -growth, drives, sex, survival and etc.
The hypothalamus sends sgnals from the different gland organs in the body that either exhibits or inhibits the activity of that particular gland releasing hormone.
Diseases are the most deadly compared to water supply, tornados, and access to food. And more and more people are dying from diseases as the world gets worse .
