A flatworm obtains oxygen needed for cellular respiration through simple diffusion. A human obtains oxygen by breathing it in from the air and into the lungs. Which system is the flatworm missing?

Answers

Answer 1
Answer: Flatworms are high-flattened organisms dependent on direct diffusion as means of oxygen intake and release of carbon. This small organisms lack "fully evolved respiratory tissues such as lungs or gills and complex circulatory system as means to transport oxygen through out the body. 
>Direct diffusion of gases through the outer membranes can be used by organisms such as flatworms as a means of respiration due to their small size and simplicity.

Glucose can be classified as both of the following terms

Answers

Glucose is a simple sugar that falls within the carbohydrate family. It's classified as a carbohydrate because of its similarity in structure to other carbohydrates and as a monosaccharide, indicating its status as a basic sugar unit. Glucose plays a significant role in providing energy to the body via ATP production.

Glucose can be classified as both a carbohydrate and a monosaccharide. Carbohydrates are organic molecules made up of carbon, hydrogen, and oxygen atoms.

They can exist as simple sugars, such as glucose and fructose, as well as complex sugars, like starch and glycogen. The term saccharide is derived from the Greek word for sugar and is often used to denote sugars. Monosaccharide refers to sugars that are the most basic unit like glucose and fructose.

Glucose, specifically, is a simple sugar that serves as a major source of energy for all cells. It's the most readily available form of energy for the body following the digestive process. It's transformed into ATP (Adenosine triphosphate), the main energy currency within a cell, via glycolysis.

Excess glucose is transformed into glycogen and stored in the liver for later usage. The fact that Glucose can be classed as a monosaccharide and carbohydrate stem from its structural properties and its role in providing energy to the body.

Answer:

hope this helps :)

Explanation:

Monosaccharides contain a single unit; disaccharides contain two sugar units; and polysaccharides contain many sugar units as in polymers - most contain glucose as the monosaccharide unit. Number of Carbons: Monosaccharides can be further classified by the number of carbons present.

T cells are programmed to provide humoral immunity true or false

Answers

Answer: False

Explanation:

Humoral immunity depends on B Cells whereas cell immunity depends on T Cells.

Final answer:

T cells are not programmed to provide humoral immunity, which is primarily mediated by B cells. T cells are involved in cell-mediated immunity where they directly attack and destroy infected cells.

Explanation:

T cells are not programmed to provide humoral immunity. Humoral immunity, also known as antibody-mediated immunity, is primarily mediated by B cells which produce antibodies specific to each pathogen. T cells, on the other hand, are involved in cell-mediated immunity where they directly attack and destroy infected cells. Memory cells are a type of B and T cells that form after exposure to a pathogen and mount rapid responses upon subsequent exposures.
