Question

Study specimens B and C and answer questions 1(a) to 1(e). (a) (i) Name two biological processes that would take place in specimen B during digestion.

ScanSolve AI Tutor · Accepted Answer

Assuming Specimen B refers to the digestive system of a bird, based on the mention of "gizzard" and "stomach" in part (a)(ii).

a) (i)

Identify biological processes in digestion.
Two main biological processes that occur during digestion are mechanical digestion and chemical digestion.
- Mechanical digestion
- Chemical digestion
a) (ii)
Identify where these processes occur in a bird's digestive system.
In a bird's digestive system:
- Mechanical digestion occurs in the gizzard.
- Chemical digestion occurs in the proventriculus (glandular stomach).
  
  Mechanical digestion: Gizzard
  
  Chemical digestion: Stomach (or proventriculus)
b)
State two observable features adapting a bird's digestive system to its function.
Two observable features that adapt a bird's digestive system for digestion are:
- Presence of a gizzard for grinding food.
- Absence of teeth, with a beak and gizzard performing the function of mastication.
- Presence of a crop for temporary food storage.
  
  Presence of a gizzard
  
  Absence of teeth
c)
Name two digestive enzymes found in a bird's digestive system.
Two digestive enzymes that could be found in a bird's digestive system are:
- Amylase (for carbohydrate digestion)
- Pepsin (for protein digestion)
  
  Amylase
  
  Pepsin
d)
Identify the part for temporary food storage in a bird's digestive system.
The part of a bird's digestive system used for temporary storage of food is the crop.
- The part used for temporary storage of food is the crop.

Study specimens B and C and answer questions 1(a) to 1(e). (a) (i) Name two biological processes that would take place in specimen B during digestion.
