Haemoglobin is found dissolved in the plasma of
1 bird
2 man
3 frog
4 earthworm
Explanation:
D Annelids have haemoglobin dissolved in plasma because they don't have a proper respiratory system and the haemoglobin is dissolved in plasma for the diffusion of gases and other materials. - Blood glands are present on the \(4^{\text {th }}5^{\text {th }}\) and \(6^{\text {th }}\) segments They produce blood cells and hemoglobin which is dissolved in blood plasma. - Earthworm has no red blood cellsheaemoglobin remains dissoleved in Plasma through which oxygen transport take place.

The enteronephric nephridia of Pheretima is consists of the following parts : I. a nephrostome II. terminal nephridial duct III. septal excretory canal IV. supra-intestinal excretory canal V. long thick walled excretory canal
1 II, V
2 I, III, IV, V
3 III, IV, V
4 I, III, IV
Explanation:
A Enteronepheric nephridia (septal nephridia) are the largest nephridia of Pheretima. A typical septal nephridia consists of three main parts i.e, - Nephrostome: It is ciliated funnel communicating with the coelom. - Body of nephridia consists of two pansa short straight lobe and a long twisted lobe. - Terminal duct: Distal limb of nephridium ends in a short and narrow duct called terminal duct.

A transverse section of Pheretima taken through the \(1^{\text {th }}\) segment is observed in microscope. Which of the following structures can be observed in the section?
3 IntestineDorsal blood vesselVentral blood vesselSupra-oesophageal vessel and Septal nephridia
4 Stomachdorsal blood vesselsub neural blood vessel and Lateral hearts
Explanation:
A Stomachdorsal blood vesselventral blood vesselsupra-oesopnogeal vesselanteriar loopsring vessel and micronephridia. Explanation- Lateral hearts occur in \(7^{\text {th }}\) and \(9^{\text {th }}\) segment intestine-extends from \(15^{\text {th }}\) to last segment subneural blood vessel extends from \(14^{\text {th }}\) segment upto posterior end. - Pharyngeal nephridia occur in \(4^{\text {th }}5^{\text {th }}\) and \(6^{\text {th }}\) segments septal nephridia occur on both faces of each inter segmental septum behind \(15^{\text {th }}\) segment. - The digestive system of earthworm is complete the following parts - mouthbuccal cavitypharynxoesophagus stomachpretyphlosolar regioninterstinalcaeca which act like livertyphlosole which increases the absorption digested food.

Which process is related to the digestive tract of detrivores?
1 Pulverisation
2 Osmosis
3 Diffusion
4 Humification
Explanation:
B Detrivores are the animals which feed on dead remains of plants and animals. - The detrivores ingest dead organic compounds through their mouthshow intracellular digestion (breakdown of complex dead organic matter into the simpler forms inside the cell) and then excreted remain through the anus.
