Answer:

The correct answer is B

Explanation:

A natural resource will always come from nature and it can be used for economic gain.

Yes, they can be used by people, but so can other resources, so the answer is not A.

Not all natural resources are unlimited, such as coal, are unlimited in quantity, so the answer is not C

Lastly, we do not leave natural resources untouched; we use them, so the answer is not D.

A spectacular marine animal has a network of glassy spicules that forms a sac-like structure. This animal does not have true tis
PolarNik [594]

Answer:

Sponges use <em><u>choanocytes</u></em> or <em><u>flagellated channels</u></em> to get nutrients from the feeding cells to other parts of their body.

Explanation:

Sponges are marine animals with a sac-shaped body. The epidermis is composed of polygonal flat cells called pinacocytes and pores protected by porocytes. Under the epidermis, there is a protein matrix called mesenchyme, which is composed of spicules and <em><u>amibocytes</u></em>. By the interior side of the sponge, there are the<em><u> choanocytes</u></em>. These are ovoid cells that can be shaping the spongocoele (internal cavity of the sponge), with an extreme attached to the mesenchyme and the other extreme projected to the spongocoele, or can be grouped in spaces called <em><u>flagellated channels</u></em>.

These animals depend on water to get oxygen and food to the inside of the sac and take excrements and reproductive cells to the outside. Sponges <em>feed on small detritus particles and suspending organisms</em> that get near the animal by water streams produced by choanocytes.

Particle size is essential. Only the small ones can get through the flagellated channels, where they get stuck to the choanocytes and are encapsulated by the cells. If the choanocytes are too small, the particle is transferred to the amibocytes for digestion. These last ones also act as food storages. Excrement products are dragged by a water stream.

Combining TCAs with warfarin creates a risk for bleeding, which should be addressed in the nursing care plan. There is no known interaction between TCAs and calcium supplements or bisphosphonates that would create a risk for hypocalcemia. TCAs do not heighten the risk of gastroesophageal reflux. TCAs can affect blood pressure, but this is unrelated to any known drug-drug interactions.
