The correct Answer is:
To determine which statements about the preen gland are true, let's analyze each statement step-by-step: 1. **Statement 1: Occur in birds** - The preen gland is indeed found in birds. It is located at the base of the tail and is responsible for secreting oil that helps in maintaining the feathers. This statement is true. 2. **Statement 2: Also known as uropygial gland** - The preen gland is also referred to as the uropygial gland. This gland produces an oily substance that birds use to coat their feathers, which helps in waterproofing and maintaining feather health. This statement is true. 3. **Statement 3: Occur in bats** - Preen glands are not found in bats. Bats are mammals and do not have feathers; therefore, they do not require a preen gland for feather maintenance. This statement is false. 4. **Statement 4: Help in digestion** - The primary function of the preen gland is not related to digestion but rather to the maintenance of feathers. It produces oil for feather lubrication and waterproofing. This statement is false. Based on the analysis: - The correct statements are: - (1) Occur in birds - True - (2) Also known as uropygial gland - True - (3) Occur in bats - False - (4) Help in digestion - False Thus, the answer is that statements 1 and 2 are true.
