Explanation:

First and foremost, we should note that plasmids used in the delivery of DNA typically consists of genes which helps in antibiotic resistance.

Based on the question given, we should note that the genes for antibiotic resistance help the transformed bacteria survive in their environment.

Which describes the missing step?
Nimfa-mama [501]

Answer:

The missing step is oxygen is removed from the water after step 3.

Explanation:

The steps listed by Xavier are:

  1. <em>Water is drawn in trough pores and enters the central cavity. </em>
  2. <em>Food is filtered and digested. </em>
  3. <em>Water leaves trough an opening at the top of the body.</em>

Porifera or sponges are aquatic, immobile invertebrates whose structure is saccular with an upper opening, the osculus.

Sponges absorb water through their pores, where the porocytes are found, and through flagellated cells -the coanocytes- the movement that allows the entrance of water to the spongocele or atrium is produced, in addition to the phagocytosis of organic elements.

Once the water is in the interior chamber of the sponges, the organic particles are phagocyted to be digested, and the oxygen is removed from the water, and passes through diffusion into the cell.  The waste products, as well as carbon dioxide, are released into the water that will be expelled through the osculus.

<u><em>In Xavier's list, the missing step is the removal of oxygen from the water, before it is expelled from the body of the sponge</em></u><em>.</em>

Do you think water is an inexhaustible resource
Anna007 [38]
I think water is indeed an inexhaustible resource. We can keep using it, but it will always come back as rain, snow, ice etc. Water energy sources are one of the biggest renewable energy sources in the world.
