Which characteristic do all protists have?
myrzilka [38]

Answer: They all survive in any environment.

Explanation: Protists have the ability to survive in any environment, even extreme environment. They can live in the ocean, desert or extremely hot environment, or even a extremely cold environment.

I'll explain why the others aren't correct.

Protists can be both unicellular and multicellular, they're not always unicellular. Kingdom Protista contains all eukaryotics, so they're not always unicelluar.

Protist cannot make or consume food. Animals consume food, and plants make food, not protista. Yes they're many plant-like protists out there, such as algae, they get their food from the sun above. So all protists cannot make or consume food.

Protist does have flagella, but not all protists. Protists that are motile and generate movement have flagella, meaning they move. Not all protist move, like plants can't move. So, not all protists have flagella, meaning they can move.

Let me know if you have any questions.

Because it is difficult to excrete iron once it is in the body, iron balance is maintained primarily through absorption. The iro
Rzqust [24]
<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
