I think this view is NOT compatible with either of these hypothesis illustrated above. This is because each hypothesis presents prokaryotes as two separate groups. Prokaryotes are unicellular organism that lacks a membrane-bound nucleus, mitochondria, or any other membrane bound organelle unlike the eukaryotes which has the membrane bound nucleus and other organelles.
The skeleton of an embryo is made up of cartilage and collagen

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.
Answer:
The correct option is this: AN INCREASE IN FLUID TAKEN BY MOUTH WOULD REDUCE THE AMOUNT PRODUCED BY METABOLISM.
Explanation:
Generally, the amount of water consumed by a person normally leads to increase in the amount of urine that the person will excrete, that is, the higher the quantity of water consumed, the higher the quantity of the urine that will be excreted under normal circumstances. Thus, the statement given in option B is false. The statements given in Option C and D are right; during exercise the quantity of sweat produce and lost by the body is higher than the one that is produced when one is not exercising. Also, diarrhea usually lead to loss of water from the body.
