Answer:

b. prostate gland

Explanation:

The main function of the prostate gland is to produce and store the prostate fluid, a light colored fluid with slightly alkaline properties (pH 7.29). This fluid is meant to nourish and protect sperm in the semen (making it more liquid).

Prostatic fluid, along with the seminal fluid produced by the seminal vesicles and the sperm produced in the testis, form semen. Prostatic fluid constitutes up to about 30% of the semen.

<h2>Smallpox Vaccine</h2>

Explanation:

The smallpox vaccine is the best way to forestall smallpox.
The immunization is produced using an infection called vaccinia, which is another pox-type infection identified with smallpox.
Immunization began as a technique for the anticipation of smallpox by conscious presentation of material from smallpox pustules into the skin.
This for the most part delivered a less extreme contamination than normally procured smallpox, yet at the same time initiated invulnerability to it.
It created insusceptibility as a rule, however it likewise murdered a few people and added to smallpox outbreaks.

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.
