Small intestine is the organ which has villi contains large surface area for absorption.

The small intestine has a tendency to be the region of finest absorption ability for most drugs due to its large surface region, the presence of both energetic and passive absorption mechanisms, and close to neutral pH.

But, about ninety five percent of nutrient molecules are absorbed inside the small intestine. The absorption of most people of these molecules takes area in the second a part of the  small intestine, called the jejunum. Absorption refers to the movement of nutrients, water and electrolytes from the lumen of the small gut into the mobile, then into the blood.

The small intestine is right for absorption since it has a huge inner surface location. That is shaped due to the plicae circulates which undertaking many tiny finger-like systems of tissue called villi. The character epithelial cells also have finger-like projections, which can be referred to as referred to as microvilli.

sweet-ann [11.9K]

Mold is considered a multicellular organism, made up of many fungi cells. Thus the correct answer is option (C) Multicellular Organism.

Multicellular organisms are made up of many cells thus it is different from unicellular organisms.

Some organisms, such as slime molds and social amoebae of the genus Dictyostelium, have both uni- and multicellular structures. These include every type of animal, as well as most fungi, terrestrial plants, and algae.

Colonies of identical individuals that come together to form organisms are called colonies. However, it can be difficult to distinguish between "colonial protists" and "real multicellular organisms" because the terms are interchangeable (colonial protists are occasionally referred to as "pluricellular").

A fungus with many cells is called mold. It is made up of hyphal filaments, which can group together to form mycelia. A mycelium is a collection of mycelia, and these structures make up the thallus, or body, of the mold.

The complete question is:

Mold is made up of many fungi cells. Mold would be considered what type of organism?

A. unicellular

B. prokaryotic

C. multicellular
