  2. Small hairlike structures present on the unicellular organisms

  3. Long, tube like structure coming out of the mouth

A Correct answer
Explanation

Pseudopods which translates to "false feet" are temporary cytoplasm-filled parts of the cell wall that are able to change their form in order to move. They are used in some eukaryotic cells to move around or to eat. Most cells that do this are called as amoeboids. The Amoeba is a common example. Proboscis, cilia and tongue are absent in Amoeba. 

Therefore, the correct answer is option A.

Digestion within a digestive tract is

  1. Incomplete

  2. Extracellular

  3. The same as absorption

  4. Intracellular
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
  • Extracellular digestion is a process in which saprobionts feed by secreting enzymes through the cell membrane onto the food.
  • The enzymes catalyze the digestion of the food into molecules small enough to be taken up by passive diffusion, transport or phagocytosis.
  • Intracellular digestion is a form of digestion wherein the breaking down of materials into smaller components takes place inside the cell.
  • An incomplete digestive system has only one opening. The food goes in the same opening that the waste comes out.

Therefore, the correct answer is option B.

Cartilage matrix is digested during its osteogenesis through

  1. Intracellular autophagic activity

  2. Extracellular lysosomal activity

  3. Intracellular heterophagic activity

  4. Both B and C.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

During osteogenesis, the degradation of the cartilage matrix is mediated by enzymes secreted into the extracellular space, characterizing it as an extracellular lysosomal activity.

Assertion  :  Trypsin helps in blood digestion of predator animals.

Reason  :    Trypsin hydrolyzes fibrinogen


  1. If both the assertion and the reason are true and the reason

    is a correct explanation of the assertion

  2. If both the assertion and reason are true but the reason is

    not a correct explanation of the assertion

  3. If the assertion is true but the reason is false

  4. If both the assertion and reason are false

  5. If the assertion is false but reason is true
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Trypsin is protein digesting enzyme present in the intestine of animals. Though it cannot digest casein (a milk protein), in predator animals drinking the blood of their prey, trypsin hydrolyzes fibrinogen of blood into fibrin, leading to blood coagulation thus help in blood digestion. It also activates other pancreatic proteases.
