Hello!
The task that an average elementary-age girl would perform better than an elementary-age boy would be writing her name in cursive.
The incorrect statement is: C) It transports mainly sugars and amino acids.
Xylem together with floem is a plant tissue involved in the transport of substances through the plant.
Xylem’s role is to transport water (sometimes and nutrients) from roots to stems and leaves and to provide support to the plant. Xylem consists of a specialized, water-conducting cells - tracheary elements (tracheids and vessel) which are long, narrow and hollow.
The answer is simple dominant
<h2>The given statement is true</h2>
Explanation:
Iron absorption occurs in the duodenum and upper jejunum of small intestine
- At physiological pH ferrous iron is rapidly oxidized to the insoluble ferric form
- Gastric acid lowers the pH in the duodenum which enhances the solubility and uptake of ferric iron
- Once iron gets inside the enterocyte it can be stored as ferritin;Ferritin is a hollow spherical protein which helps in storage and regulation of iron levels within the body
- Ferritin molecule have ferroxidase activity which helps in the mobility of Fe2+ out of the enterocyte by ferroportin
- Transferrin is the major iron transport protein which transports iron through blood
- Fe3+ binds to transferrin so Fe2+ transported through ferroportin must be oxidized to Fe3+
- Fe2+ needs to be oxidized first so that it can be transported through ferroportin
- Once iron gets inside the cell it can be used for various cellular processes
