7 0

Answer:

This is because of how reproduction works in humans. Male and female sex cells are formed by a process called meiosis, where the diploid chromosomes divide and separate. And so the ratio of male to female births is also 50:50.

Describe the path blood takes through the circulatory
ratelena [41]
Ooh this will be good

So blood let’s say starts in the left atrium where it goes down through the mitral valve into the left ventricle. From the left ventricle of the blood is pushed through the aorta and from there through the various branches of the body eventually allowing oxygen rich blood to flow all across the body. Once this blood is picked up by veins as deoxygenated blood it goes back to the heart through the inferior and superior vena cava. From there the deoxygenated blood is sent into the right atrium, through the tricuspid vale into the right ventricle, through the pulmonic valve into the pulmonary artery and into the lungs for re-oxygenation. The re-oxygenated blood (oxygen rich blood) now goes through the pulmonary veins into the left atrium and the cycle beings again.


Remember this, Left side of heart is for oxygenated blood, Right side of heart is for deoxygenated blood.

Artery takes oxygen rich blood away from heart itself
Vein takes oxygen poor blood back into the heart

Exceptions, Pulmonary Artery takes oxygen poor blood away from heart and into lungs

Pulmonary vein takes oxygen rich blood into the left atrium to be pushed to the rest of e body.

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>
