professor190 [17]

Metanephridia differ from protonephridia in that selective reabsorption of materials occurs via cells lining the tubules in protonephridia and via capillaries in metanephridia is true.

<h3>What are the Metanephridia?</h3>

Metanephridia gather the liquid from the celomatic hollow space via a funnel-like shape known as nephrostome. The coelomic fluid enters the tubulus, water and vitamins are reabsorbed, and the metabolic waste inclusive of ammonia, urea, or uric acid is excreted.

The principal distinction among protonephridia and metanephridia is that protonephridia are a community of dead-give up tubules with out inner openings, while metanephridia are a kind of excretory glands with a ciliated funnel starting into the frame hollow space.

Two parallel electrodes that are typically separated by 3cm with a 5V potential difference across them.
Romashka-Z-Leto [24]

Answer:

166.7 V/m or 166.7 J/C

Explanation:

The formula for electric field is

volts/distance

Given

volts = 5V

Distance =0.03m

= 5V / 0.03m

= 166.7 V/m

Recall

1 V/m = 1 J/C

The magnitude of the electric field between the two electrodes in ionization type detectors = 166.7 V/m or 166.7 J/C
