An unidentified prokaryotic cell. Thus, option "4" is correct.
<h3>What atr prokaryotes and eukaryotes?</h3>
Prokaryotes are the unicellular organisms that do not contain nucleus and membrane bound organelle in their cell. Their genetic material is present in the cytoplasm.
On the other hand, eukaryotes have true nucleus that contains the genetic material (DNA). They also contain membrane bound specialised organelles (such as mitochondria, endoplasmic reticulum, golgi complex).
Thus, option "4" is correct.

Answer:
Higher pressure in glomerular capillaries than in the surrounding Bowman's capsule.
Explanation:
The renal corpuscle is composed of the capillary glomerulus and the Bowman's capsule that covers it, there is a space inside the capsule, Bowman's space, where the filtered liquid from the glomerulus passes. The glomerular pressure must be higher than in the surrounding Bowman's capsule, so in that way it forces the filtration and tends to expel fluid from the glomeruli, allowing the passage of water, small molecules of solute and ions.
