The difference between a multicellular organism and a colonial organism is that colonial organism consists of individual one-celled organisms that can, if separated, survive on their own. On the other hand, cells from a multicellular life-form cannot live independently (they are all connected to function together).

Volvox is not considered multicellular because its cells are not aggregated into organized tissues and have no organ and organ systems.

The difference between a multicellular organism and a colonial organism is that individual organisms from a colony can, if separated, survive on their own, while cells from a multicellular lifeform (e.g., cells from a brain) cannot.

Volvox is indeed multicellular because they are a bunch of unicells forming colonies. But they did not give rise to land plants. Another group called the charophytes did! They are green algae, multicellular and possessing some similarities to land plants. For example, they have sporopollenin on their walls.

Cellular respiration is the process that converts nutrients into ATP (adenosine triphosphate), a storage molecule that provides

Genrish500 [490]

Answer:

Plants perform photosynthesis and cellular respiration.

Explanation:

Cellular respiration is the conversion of glucose into ATP and energy yielding molecules such as NADH and FADH2 along with water and oxygen and carbon dioxide as by-products.
Cellular respiration is a process that occurs both in autotrophs and heterotrophs.
Only the final stage of cellular respiration i.e. oxidative phosphorylation or electron transport chain requires oxygen as the final electron acceptor.
Heterotrophic cells don't take in carbondioxide, they utilize glucose obtained through food.

The body loses water in a variety of ways. Put the water output mechanisms in order from greatest contribution to fluid loss (1)

kirza4 [7]

The maximum to minimum body water loss occurs by: Urine production, Skin losses, Lung respiration and minimum by Feces

<h3>What are the ways in which body loses water ?</h3>

Through breathing, sweating, and peeing, the body continuously loses water. You become dehydrated if you don't drink enough water or other liquids.

The majority of fluid loss happens through the stools, sweat, and urine, but it's not only those things. The quantity of body fluid lost daily through the skin, respiratory system, and water in the feces that cannot be readily measured is known as insensible fluid loss.

Physical exercise also influences increased respiratory water loss due to the increased expiratory volume and frequency of breathing. Various environmental elements like temperature, humidity, radiation, and atmospheric pressure mostly affect sweating and urine water loss.
