Active and passive humoral immunity are both mechanisms of adaptive immunity that use antibodies. yes this is true

Our adaptive immune system protects us from infection-related mortality. An new-born born with a significantly compromised adaptive immune system may die shortly unless extreme steps are taken to isolate it from a wide range of infectious agents such as bacteria, viruses, fungi, and parasites.
The purpose of adaptive immunity is to eliminate invading infections as well as any harmful chemicals they create. Because these reactions are damaging, it is critical that they only occur in response to molecules that are alien to the host and not to molecules that are native to the host. The adaptive immune system's capacity to identify what is foreign from what is self is a fundamental feature.

What is the difference between embolus and thrombus

ryzh [129]

An embolus is anything which travels through the blood vessels until it reaches a vessel that is too small to let it pass through, and this causes the blood flow to stop. Basically, a thrombus is the blood clot itself, and the embolus is a fraction of the blood clot which travels through the blood vessels.

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:

Water is drawn in trough pores and enters the central cavity.
Food is filtered and digested.
Water leaves trough an opening at the top of the body.

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.

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.
